Abstract
This package provides a flexible and easy interface to page dimensions. You can change the page
layout with intuitive parameters. For instance, if you want to set a margin to 2cm from each edge of
the paper, you can type just \usepackage[margin=2cm]{geometry}. The page layout can be changed
in the middle of the document with \newgeometry command.

1 Preface to version 5
• Changing page layout mid-document.
The new commands \newgeometry{· · ·} and \restoregeometry allow users to change page dimen-
sions in the middle of the document. \newgeometry is almost similar to \geometry except that
\newgeometry disables all the options specified in the preamble and skips the papersize-related
options: landscape, portrait and paper size options (such as papersize, paper=a4paper and so
forth).
• A new set of options to specify the layout area.
The options specified for the area, in which the page dimensions are calculated, are added: layout,
layoutsize, layoutwidth, layoutheight and so forth. These options would help to print the specified
layout to a different sized paper. For example, with a4paper and layout=a5paper, the geometry
package uses ‘A5’ layout to calculate margins with the paper size still ‘A4’.
• A new driver option xetex.
The new driver option xetex is added. The driver auto-detection routine has been revised so as
to avoid an error with undefined control sequences. Note that ‘geometry.cfg’ in TEX Live, which
disables the auto-detection routine and sets pdftex, is no longer necessary and has no problem even
though it still exists. To set xetex is strongly recommended with XELATEX.
• New paper size presets for JIS B-series and ISO C-series.
The papersize presets b0j to b6j for JIS (Japanese Industrial Standards) B-series and c0paper to
c6paper for ISO C-series (v5.4∼) are added.
• Changing default for underspecified margin.
In the previous version, if only one margin was specified, bottom=1cm for example, then geometry
set the other margin with the margin ratio (1:1 by default for the vertical dimensions) and got
top=1cm in this case. The version 5 sets the text-body size with the default scale (= 0.7) and
determine the unspecified margin. (See Section 6.5)
• The option showframe and showcrop works on every page.
With showframe option, the page frames are shown on every page. In addition, a new option
showcrop prints crop marks at each corner of layout area on every page. Note that the marks would
be invisible without specifying the layout size smaller than paper size. Version 5.4 introduced a
new \shipout overloading process using atbegshi package, so the atbegshi package is required when
showframe or showcrop option is specified.
• Loading geometry.cfg precedes processing class options.
The previous version loaded geometry.cfg after processing the document class options. Now that
the config file is loaded before processing the class options, you can change the behavior specified
in geometry.cfg by adding options into \documentclass as well as \usepackage and \geometry.

 • Deleted options: compat2 and twosideshift. The version 5 has no longer compatibility with
the previous ones. compat2 and twosideshift are gone for simplicity.

2 Introduction
To set dimensions for page layout in LATEX is not straightforward. You need to adjust several LATEX
native dimensions to place a text area where you want. If you want to center the text area in the paper
you use, for example, you have to specify native dimensions as follows:
\usepackage{calc}
\setlength\textwidth{7in}
\setlength\textheight{10in}
\setlength\oddsidemargin{(\paperwidth-\textwidth)/2 - 1in}
\setlength\topmargin{(\paperheight-\textheight
-\headheight-\headsep-\footskip)/2 - 1in}.
Without package calc, the above example would need more tedious settings. Package geometry provides
an easy way to set page layout parameters. In this case, what you have to do is just
\usepackage[text={7in,10in},centering]{geometry}.
Besides centering problem, setting margins from each edge of the paper is also troublesome. But geometry
also make it easy. If you want to set each margin to 1.5in, you can type
\usepackage[margin=1.5in]{geometry}
Thus, the geometry package has an auto-completion mechanism, in which unspecified dimensions are
automatically determined. The geometry package will be also useful when you have to set page layout
obeying the following strict instructions: for example,
The total allowable width of the text area is 6.5 inches wide by 8.75 inches high. The top
margin on each page should be 1.2 inches from the top edge of the page. The left margin
should be 0.9 inch from the left edge. The footer with page number should be at the bottom
of the text area.
In this case, using geometry you can type
\usepackage[total={6.5in,8.75in},
top=1.2in, left=0.9in, includefoot]{geometry}.
Setting a text area on the paper in document preparation system has some analogy to placing a
window on the background in the window system. The name ‘geometry’ comes from the -geometry
option used for specifying a size and location of a window in X Window System.

3 Page geometry
Figure 1 shows the page layout dimensions defined in the geometry package. The page layout contains a
total body (printable area) and margins. The total body consists of a body (text area) with an optional
header, footer and marginal notes (marginpar). There are four margins: left, right, top and bottom. For
twosided documents, horizontal margins should be called inner and outer.
paper : total body and margins
total body : body (text area) (optional head, foot and marginpar)
margins : left (inner), right (outer), top and bottom
Each margin is measured from the corresponding edge of a paper. For example, left margin (inner
margin) means a horizontal distance between the left (inner) edge of the paper and that of the total
body. Therefore the left and top margins defined in geometry are different from the native dimensions
\leftmargin and \topmargin. The size of a body (text area) can be modified by \textwidth and
\textheight. The dimensions for paper, total body and margins have the following relations.

paperwidth = left + width + right (1)

paperheight = top + height + bottom (2)

pages are swapped by twoside option, margins specified by left and right options are
used for the inside and outside margins respectively. inner and outer are aliases of left
and right respectively.

Figure 2: includehead and includefoot include the head and foot respectively into total body. (a)
height = textheight (default). (b) height = textheight + headheight + headsep +
footskip if includehead and includefoot. If the top and bottom margins are specified,
includehead and includefoot result in shorter textheight.

The total body width and height would be defined:

width := textwidth (+ marginparsep + marginparwidth) (3)

height := textheight (+ headheight + headsep + footskip) (4)

In Equation (3) width:=textwidth by default, while marginparsep and marginparwidth are included in
width if includemp option is set true. In Equation (4), height:=textheight by default. If includehead
is set to true, headheight and headsep are considered as a part of height. In the same way, includefoot
takes footskip into height. Figure 2 shows how these options work in the vertical direction.
Thus, the page layout consists of three parts (lengths) in each direction: one body and two margins. If
the two of them are explicitly specified, the other length is obvious and no need to be specified. Figure 3
shows a simple model of page dimensions. When a length L is given and is partitioned into the body b,
the margins a and c, it’s obvious that
L=a+b+c (5)
The specification with two of the three (a,b and c) fixed explicitly is solvable. If two or more are left
unspecified or ‘underspecified’, Equation (5) cannot be solved without any other relation between them.
If all of them are specified, then it needs to check whether or not they satisfy Equation (5), that is too
much specification or ‘overspecified’.

Figure 3: A simple model of page dimensions.

The geometry package has auto-completion mechanism that saves the trouble of specifying the page
layout dimensions. For example, you can set

\usepackage[width=14cm, left=3cm]{geometry}
on A4 paper. In this case you don’t have to set the right margin The details of auto-completion will be
described in Section 6.5.

4 User interface
4.1 Commands
The geometry package provides the following commands:
• \geometry{hoptionsi}
• \newgeometry{hoptionsi} and \restoregeometry
• \savegeometry{hnamei} and \loadgeometry{hnamei}

\geometry{hoptionsi} changes the page layout according to the options specified in the argument.
This command, if any, should be placed only in the preamble (before \begin{document}).
The geometry package may be used as part of a class or another package you use in your document.
The command \geometry can overwrite some of the settings in the preamble. Multiple use of \geometry
is allowed and then processed with the options concatenated. If geometry is not yet loaded, you can use
only \usepackage[hoptionsi]{geometry} instead of \geometry.
\newgeometry{hoptionsi} changes the page layout mid-document. \newgeometry is almost similar to
\geometry except that \newgeometry disables all the options specified by \usepackage and \geometry
in the preamble and skips papersize-related options. \restoregeometry restores the page layout specified
in the preamble. This command has no arguments. See Section 7 for details.
\savegeometry{hnamei} saves the page dimensions as hnamei where you put this command.
\loadgeometry{hnamei} loads the page dimensions saved as hnamei. See Section 7 for details.

4.2 Optional argument

The geometry package adopts keyval interface ‘hkeyi=hvaluei’ for the optional argument to \usepackage,
\geometry and \newgeometry.
The argument includes a list of comma-separated keyval options and has basic rules as follows:
• Multiple lines are allowed, while blank lines are not.
• Any spaces between words are ignored.
• Options are basically order-independent. (There are some exceptions. See Section 6.2 for details.)
For example,
\usepackage[ a5paper , hmargin = { 3cm,
.8in } , height
= 10in ]{geometry}
is equivalent to
\usepackage[height=10in,a5paper,hmargin={3cm,0.8in}]{geometry}
Some options are allowed to have sub-list, e.g. {3cm,0.8in}. Note that the order of values in the sub-list
is significant. The above setting is also equivalent to the followings:

4
 \usepackage{geometry}
\geometry{height=10in,a5paper,hmargin={3cm,0.8in}}

or
\usepackage[a5paper]{geometry}
\geometry{hmargin={3cm,0.8in},height=8in}
\geometry{height=10in}.
Thus, multiple use of \geometry just appends options.
geometry supports package calc 1 . For example,
\usepackage{calc}
\usepackage[textheight=20\baselineskip+10pt]{geometry}

4.3 Option types

geometry options are categorized into four types:

1. Boolean type
takes a boolean value (true or false). If no value, true is set by default.
hkeyi=true false.
hkeyi with no value is equivalent to hkeyi=true.

Examples: verbose=true, includehead, twoside=false.

Paper name is the exception. The preferred paper name should be set with no values. Whatever
value is given, it is ignored. For instance, a4paper=XXX is equivalent to a4paper.
2. Single-valued type
takes a mandatory value.

hkeyi=hvaluei.
Examples: width=7in, left=1.25in, footskip=1cm, height=.86\paperheight.
3. Double-valued type
takes a pair of comma-separated values in braces. The two values can be shortened to one value if
they are identical.
hkeyi={hvalue1 i,hvalue2 i}.
hkeyi=hvaluei is equivalent to hkeyi={hvaluei,hvaluei}.
Examples: hmargin={1.5in,1in}, scale=0.8, body={7in,10in}.
4. Triple-valued type
takes three mandatory, comma-separated values in braces.
hkeyi={hvalue1 i,hvalue2 i,hvalue3 i}
Each value must be a dimension or null. When you give an empty value or ‘*’, it means null and
leaves the appropriate value to the auto-completion mechanism. You need to specify at least one
dimension, typically two dimensions. You can set nulls for all the values, but it makes no sense.
Examples:
hdivide={2cm,*,1cm}, vdivide={3cm,19cm, }, divide={1in,*,1in}.

This section describes all options available in geometry. Options with a dagger are not available as
arguments of \newgeometry (See Section 7).

 5.1 Paper size
The options below set paper/media size and orientation.
†
paperpapername
specifies the paper size by name. paper=hpaper-namei. For convenience, you can specify
the paper name without paper=. For example, a4paper is equivalent to paper=a4paper.

b0j, b1j, b2j, b3j, b4j, b5j, b6j,
ansiapaper, ansibpaper, ansicpaper, ansidpaper, ansiepaper,
letterpaper, executivepaper, legalpaper
specifies paper name. The value part is ignored even if any. For example, the followings
have the same effect: a5paper, a5paper=true, a5paper=false and so forth.
a[0-6]paper, b[0-6]paper and c[0-6]paper are ISO A, B and C series of paper sizes
respectively. The JIS (Japanese Industrial Standards) A-series is identical to the ISO
A-series, but the JIS B-series is different from the ISO B-series. b[0-6]j should be used
for the JIS B-series.
†
screen a special paper size with (W,H) = (225mm,180mm). For presentation with PC and
video projector, “screen,centering” with ‘slide’ documentclass would be useful.
†
paperwidth width of the paper. paperwidth=hlengthi.
†
paperheight height of the paper. paperheight=hlengthi.
†
papersize width and height of the paper. papersize={hwidthi,hheighti} or papersize=hlengthi.
†
landscape switches the paper orientation to landscape mode.
†
portrait switches the paper orientation to portrait mode. This is equivalent to landscape=false.
The options for paper names (e.g., a4paper) and orientation (portrait and landscape) can be set
as document class options. For example, you can set \documentclass[a4paper,landscape]{article},
then a4paper and landscape are processed in geometry as well. This is also the case for twoside and
twocolumn (see also Section 5.5).

5.2 Layout size

You can specify the layout area with options described in this section regardless of the paper size. The
options would help to print the specified layout to a different sized paper. For example, with a4paper
and layout=a5paper, the package uses ‘A5’ layout to calculate margins on ’A4’ paper. The layout size
defaults to the same as the paper. The options for the layout size are available in \newgeometry, so that
you can change the layout size in the middle of the document. The paper size itself can’t be changed
though. Figure 4 shows what the difference between layout and paper is.

layout specifies the layout size by paper name. layout=hpaper-namei. All the paper names
defined in geometry are available. See Section 5.1 for details.
layoutwidth width of the layout. layoutwidth=hlengthi.
layoutheight height of the layout. layoutheight=hlengthi.
layoutsize width and height of the layout. layoutsize={hwidthi,hheighti} or
layoutsize=hlengthi.
layouthoffset specifies the horizontal offset from the left edge of the paper. layouthoffset=hlengthi.
layoutvoffset specifies the vertical offset from the top edge of the paper. layoutvoffset=hlengthi.
layoutoffset specifies both horizontal and vertical offsets. layoutoffset={hhoffseti,hvoffseti} or
layoutsize=hlengthi.

5.3 Body size

The options specifying the size of total body are described in this section.

hscale ratio of width of total body to \paperwidth. hscale=hh-scalei, e.g., hscale=0.8 is

equivalent to width=0.8\paperwidth. (0.7 by default)

Figure 4: The dimensions related to the layout size. Note that the layout size defaults to
the same size as the paper, so you don’t have to specify layout-related options
explicitly in most cases.

vscale ratio of height of total body to \paperheight, e.g., vscale=hv-scalei. (0.7 by default)
vscale=0.9 is equivalent to height=0.9\paperheight.
scale ratio of total body to the paper. scale={hh-scalei,hv-scalei} or scale=hscalei. (0.7 by
default)
width totalwidth
width of total body. width=hlengthi or totalwidth=hlengthi. This dimension defaults to
textwidth, but if includemp is set to true, width ≥ textwidth because width includes
the width of the marginal notes. If textwidth and width are specified at the same time,
textwidth takes priority over width.
height totalheight
height of total body, excluding header and footer by default. If includehead or
includefoot is set, height includes the head or foot of the page as well as textheight.
height=hlengthi or totalheight=hlengthi. If both textheight and height are
specified, height will be ignored.
total width and height of total body.
total={hwidthi,hheighti} or total=hlengthi.
textwidth specifies \textwidth, the width of body (the text area). textwidth=hlengthi.
textheight specifies \textheight, the height of body (the text area). textheight=hlengthi.
text body specifies both \textwidth and \textheight of the body of page.
body={hwidthi,hheighti} or text=hlengthi.
lines enables users to specify \textheight by the number of lines. lines=hinteger i.
includehead includes the head of the page, \headheight and \headsep, into total body. It is set to
false by default. It is opposite to ignorehead. See Figure 2 and Figure 5.
includefoot includes the foot of the page, \footskip, into total body. It is opposite to ignorefoot.
It is false by default. See Figure 2 and Figure 5.
includeheadfoot
sets both includehead and includefoot to true, which is opposite to
ignoreheadfoot. See Figure 2 and Figure 5.
includemp includes the margin notes, \marginparwidth and \marginparsep, into body when
calculating horizontal calculation.
includeall sets both includeheadfoot and includemp to true. See Figure 5.
ignorehead disregards the head of the page, headheight and headsep, in determining vertical
layout, but does not change those lengths. It is equivalent to includehead=false. It is
set to true by default. See also includehead.
ignorefoot disregards the foot of page, footskip, in determining vertical layout, but does not
change that length. This option defaults to true. See also includefoot.
ignoreheadfoot
sets both ignorehead and ignorefoot to true. See also includeheadfoot.

true, the location of the marginal notes are swapped on every page. Option twoside
swaps both margins and marginal notes on verso pages. Note that the marginal note, if
any, is printed despite ignoremp or includemp=false and overrun the page in some cases.

ignoremp disregards the marginal notes in determining the horizontal margins (defaults to true).
If marginal notes overrun the page, the warning message will be displayed when
verbose=true. See also includemp and Figure 5.
ignoreall sets both ignoreheadfoot and ignoremp to true. See also includeall.
heightrounded
This option rounds \textheight to n-times (n: an integer) of \baselineskip plus
\topskip to avoid “underfull vbox” in some cases. For example, if \textheight is
486pt with \baselineskip 12pt and \topskip 10pt, then

(39 × 12pt + 10pt =) 478pt < 486pt < 490pt (= 40 × 12pt + 10pt),
as a result \textheight is rounded to 490pt. heightrounded=false by default.

Figure 5 illustrates various layouts with different layout modes. The dimensions for a header and a
footer can be controlled by nohead or nofoot mode, which sets each length to 0pt directly. On the other
hand, options with the prefix ignore do not change the corresponding native dimensions.
The following options can specify body and margins simultaneously with three comma-separated
values in braces.

hdivide horizontal partitions (left,width,right). hdivide={hleft margini,hwidthi,hright

margini}. Note that you should not specify all of the three parameters. The best way of
using this option is to specify two of three and leave the rest with null(nothing) or ‘*’.
For example, when you set hdivide={2cm,15cm, }, the margin from the right-side edge
of page will be determined calculating paperwidth-2cm-15cm.

8
vdivide vertical partitions (top,height,bottom). vdivide={htop margini,hheighti,hbottom
margini}.
divide divide={A,B,C} is interpreted as hdivide={A,B,C} and vdivide={A,B,C}.

5.4 Margin size

The options specifying the size of the margins are listed below.

left lmargin inner

left margin (for oneside) or inner margin (for twoside) of total body. In other words, the
distance between the left (inner) edge of the paper and that of total body.
left=hlengthi. inner has no special meaning, just an alias of left and lmargin.
right rmargin outer
right or outer margin of total body. right=hlengthi.
top tmargin top margin of the page. top=hlengthi. Note this option has nothing to do with the
native dimension \topmargin.
bottom bmargin
bottom margin of the page. bottom=hlengthi.
hmargin left and right margin. hmargin={hleft margini,hright margini} or hmargin=hlengthi.
vmargin top and bottom margin. vmargin={htop margini,hbottom margini} or
vmargin=hlengthi.
margin margin={A,B} is equivalent to hmargin={A,B} and vmargin={A,B}. margin=A is
automatically expanded to hmargin=A and vmargin=A.
hmarginratio horizontal margin ratio of left (inner) to right (outer). The value of hratioi should be
specified with colon-separated two values. Each value should be a positive integer less
than 100 to prevent arithmetic overflow, e.g., 2:3 instead of 1:1.5. The default ratio is
1:1 for oneside, 2:3 for twoside.
vmarginratio vertical margin ratio of top to bottom. The default ratio is 2:3.
marginratio ratio
horizontal and vertical margin ratios. marginratio={hhorizontal ratioi,hvertical ratioi}
or marginratio=hratioi.
hcentering sets auto-centering horizontally and is equivalent to hmarginratio=1:1. It is set to
true by default for oneside. See also hmarginratio.
vcentering sets auto-centering vertically and is equivalent to vmarginratio=1:1. The default is
false. See also vmarginratio.
centering sets auto-centering and is equivalent to marginratio=1:1. See also marginratio. The
default is false. See also marginratio.
twoside switches on twoside mode with left and right margins swapped on verso pages. The
option sets \@twoside and \@mparswitch switches. See also asymmetric.
asymmetric implements a twosided layout in which margins are not swapped on alternate pages (by
setting \oddsidemargin to \evensidemargin + bindingoffset) and in which the
marginal notes stay always on the same side. This option can be used as an alternative
to the twoside option. See also twoside.
bindingoffset
removes a specified space from the lefthand-side of the page for oneside or the inner-side
for twoside. bindingoffset=hlengthi. This is useful if pages are bound by a press
binding (glued, stitched, stapled . . . ). See Figure 6.
hdivide See description in Section 5.3.
vdivide See description in Section 5.3.
divide See description in Section 5.3.

5.5 Native dimensions

The options below overwrite LATEX native dimensions and switches for page layout (See the right-hand
side in Figure 1).

Figure 6: The option bindingoffset adds the specified length to the inner margin. Note that
twoside option swaps the horizontal margins and the marginal notes together with
bindingoffset on even pages (see b)), but asymmetric option suppresses the swap of the
margins and marginal notes (but bindingoffset is still swapped).

headheight head
modifies \headheight, height of header. headheight=hlengthi or head=hlengthi.
headsep modifies \headsep, separation between header and text (body). headsep=hlengthi.
footskip foot
modifies \footskip, distance separation between baseline of last line of text and
baseline of footer. footskip=hlengthi or foot=hlengthi.
nohead eliminates spaces for the head of the page, which is equivalent to both
\headheight=0pt and \headsep=0pt.
nofoot eliminates spaces for the foot of the page, which is equivalent to \footskip=0pt.
noheadfoot equivalent to nohead and nofoot, which means that \headheight, \headsep and
\footskip are all set to 0pt.
footnotesep changes the dimension \skip\footins, separation between the bottom of text body and
the top of footnote text.
marginparwidth marginpar
modifies \marginparwidth, width of the marginal notes. marginparwidth=hlengthi.
marginparsep modifies \marginparsep, separation between body and marginal notes.
marginparsep=hlengthi.
nomarginpar shrinks spaces for marginal notes to 0pt, which is equivalent to \marginparwidth=0pt
and \marginparsep=0pt.
columnsep modifies \columnsep, the separation between two columns in twocolumn mode.
hoffset modifies \hoffset. hoffset=hlengthi.
voffset modifies \voffset. voffset=hlengthi.
offset horizontal and vertical offset.
offset={hhoffseti,hvoffseti} or offset=hlengthi.
twocolumn sets twocolumn mode with \@twocolumntrue. twocolumn=false denotes onecolumn
mode with\@twocolumnfalse. Instead of twocolumn=false, you can specify onecolumn
(which defaults to true)
onecolumn works as twocolumn=false. On the other hand, onecolumn=false is equivalent to
twocolumn.
twoside sets both \@twosidetrue and \@mparswitchtrue. See Section 5.4.
textwidth sets \textwidth directly. See Section 5.3.
textheight sets \textheight directly. See Section 5.3.
reversemp reversemarginpar
makes the marginal notes appear in the left (inner) margin with \@reversemargintrue.
The option doesn’t change includemp mode. It’s set false by default.

 5.6 Drivers
The package supports drivers dvips, dvipdfm, pdftex, luatex, xetex and vtex. You can also set
dvipdfm for dvipdfmx and xdvipdfmx The options dvipdfmx and xdvipdfmx are also supported as aliases
for the dvipdfm option. pdftex for pdflatex, and vtex for VTEX environment. The driver options are
exclusive. The driver can be set by either driver=hdriver namei or any of the drivers directly like pdftex.
By default, geometry guesses the driver appropriate to the system in use. Therefore, you don’t have to
set a driver in most cases. However, if you want to use dvipdfm, you should specify it explicitly.
†
driver specifies the driver with driver=hdriver namei. dvips, dvipdfm, pdftex, luatex, vtex,
xetex, auto and none are available as a driver name. The names except for auto and
none can be specified directly with the name without driver=. driver=auto makes the
auto-detection work whatever the previous setting is. driver=none disables the
auto-detection and sets no driver, which may be useful when you want to let other
package work out the driver setting. For example, if you want to use crop package with
geometry, you should call \usepackage[driver=none]{geometry} before the crop
package.
†
dvips writes the paper size in dvi output with the \special macro. If you use dvips as a
DVI-to-PS driver, for example, to print a document with
\geometry{a3paper,landscape} on A3 paper in landscape orientation, you don’t need
options “-t a3 -t landscape” to dvips.
†
dvipdfm works like dvips except for landscape correction. You can set this option when using
dvipdfmx and xdvipdfmx to process the dvi output.
†
pdftex sets \pdfpagewidth and \pdfpageheight internally.
†
luatex sets \pagewidth and \pageheight internally.
†
xetex is the same as pdftex except for ignoring \pdf{h,v}origin undefined in XELATEX. This
option is introduced in the version 5. Note that ‘geometry.cfg’ in TEX Live, which
disables the auto-detection routine and sets pdftex, is no longer necessary, but has no
problem even though it’s left undeleted. Instead of xetex, you can specify dvipdfm with
XELATEX if you want to use specials of dvipdfm XETEX supports.
†
vtex sets dimensions \mediawidth and \mediaheight for VTEX. When this driver is selected
(explicitly or automatically), geometry will auto-detect which output mode (DVI, PDF
or PS) is selected in VTEX, and do proper settings for it.

If explicit driver setting is mismatched with the typesetting program in use, the default driver dvips
would be selected.

5.7 Other options

The other useful options are described here.
†
verbose displays the parameter results on the terminal. verbose=false (default) still puts them
into the log file.
†
reset sets back the layout dimensions and switches to the settings before geometry is loaded.
Options given in geometry.cfg are also cleared. Note that this cannot reset pass and
mag with truedimen. reset=false has no effect and cannot cancel the previous
reset(=true) if any. For example, when you go
\documentclass[landscape]{article}
\usepackage[twoside,reset,left=2cm]{geometry}
with \ExecuteOptions{scale=0.9} in geometry.cfg, then as a result, landscape and
left=2cm remain effective, and scale=0.9 and twoside are ineffective.
†
mag sets magnification value (\mag) and automatically modifies \hoffset and \voffset
according to the magnification. mag=hvaluei. Note that hvaluei should be an integer
value with 1000 as a normal size. For example, mag=1414
√ with a4paper provides an
enlarged print fitting in a3paper, which is 1.414 (= 2) times larger than a4paper. Font
enlargement needs extra disk space. Note that setting mag should precede any
other settings with ‘true’ dimensions, such as 1.5truein, 2truecm and so on.
See also truedimen option.

11
†
truedimen changes all internal explicit dimension values into true dimensions, e.g., 1in is changed
to 1truein. Typically this option will be used together with mag option. Note that this
is ineffective against externally specified dimensions. For example, when you set
“mag=1440, margin=10pt, truedimen”, margins are not ‘true’ but magnified. If you
want to set exact margins, you should set like “mag=1440, margin=10truept,
truedimen” instead.
†
pass disables all of the geometry options and calculations except verbose and showframe. It
is order-independent and can be used for checking out the page layout of the
documentclass, other packages and manual settings without geometry.
†
showframe shows visible frames for the text area and page, and the lines for the head and foot on
the first page.
†
showcrop prints crop marks at each corner of user-specified layout area.

6 Processing options
6.1 Order of loading
If there’s geometry.cfg somewhere TEX can find it, geometry loads it first. For example, in geometry.cfg
you may write \ExecuteOptions{a4paper}, which specifies A4 paper as the default paper. Basically
you can use all the options defined in geometry with \ExecuteOptions{}.
The order of loading in the preamble of your document is as follows:
1. geometry.cfg if it exists.
2. Options specified with \documentclass[hoptionsi]{...}.

3. Options specified with \usepackage[hoptionsi]{geometry}

4. Options specified with \geometry{hoptionsi}, which can be called multiple times. (reset option
will cancel the specified options ever given in \usepackage{geometry} or \geometry.)

6.2 Order of options

The specification of geometry options is order-independent, and overwrites the previous one for the same
setting. For example,
[left=2cm, right=3cm] is equivalent to [right=3cm, left=2cm].

The options called multiple times overwrite the previous settings. For example,
[verbose=true, verbose=false] results in verbose=false.
[hmargin={3cm,2cm}, left=1cm] is the same as hmargin={1cm,2cm}, where the left (or inner) margin
is overwritten by left=1cm.
reset and mag are exceptions. The reset option removes all the geometry options (except pass)
before it. If you set
\documentclass[landscape]{article}
\usepackage[margin=1cm,twoside]{geometry}
\geometry{a5paper, reset, left=2cm}

then margin=1cm, twoside and a5paper are removed, and is eventually equivalent to
\documentclass[landscape]{article}
\usepackage[left=2cm]{geometry}
The mag option should be set in advance of any other settings with ‘true’ length, such as
left=1.5truecm, width=5truein and so on. The \mag primitive can be set before this package is
called.

12
6.3 Priority
There are several ways to set dimensions of the body: scale, total, text and lines. The geometry
package gives higher priority to the more concrete specification. Here is the priority rule for body.

priority: low −→ high

     
 hscale   width   textwidth 
vscale < height < textheight < lines.
scale total text
     

For example,
\usepackage[hscale=0.8, textwidth=7in, width=18cm]{geometry}
is the same as \usepackage[textwidth=7in]{geometry}. Another example:

\usepackage[lines=30, scale=0.8, text=7in]{geometry}

results in [lines=30, textwidth=7in].

6.4 Defaults
This section sums up the default settings for the auto-completion described later.
The default vertical margin ratio is 2/3, namely,

top : bottom = 2 : 3 default. (6)

As for the horizontal margin ratio, the default value depends on whether the document is onesided or
twosided, 
1:1 default for oneside,
left (inner) : right (outer) = (7)
2:3 default for twoside.
Obviously the default horizontal margin ratio for oneside is ‘centering’.
The geometry package has the following default setting for onesided documents:

• scale=0.7 (body is 0.7 × paper)

• marginratio={1:1, 2:3} (1:1 for horizontal and 2:3 for vertical margins)
• ignoreall (the header, footer, marginal notes are excluded when calculating the size of body.)
For twosided document with twoside option, the default setting is the same as onesided except that the
horizontal margin ratio is set to 2:3 as well.
Additional options overwrite the previous specified dimensions.

6.5 Auto-completion
Figure 7 shows schematically how many specification patterns exist and how to solve the ambiguity of the
specifications. Each axis shows the numbers of lengths explicitly specified for body and margins. S(m,b)
presents the specification with a set of numbers (margin, body) = (m, b).
For example, the specification width=14cm, left=3cm is categorized into S(1,1), which is an adequate
specification. If you add right=4cm, it would be in S(2,1) and overspecified. If only width=14cm is given,
it’s in S(0,1), underspecified.
The geometry package has the auto-completion mechanism, in which if the layout parameters are
underspecified or overspecified, geometry works out the ambiguity using the defaults and other relations.
Here are the specifications and the completion rules.

S(0,0) Nothing is specified. The geometry package sets body with the default scale (= 0.7).
For example, width is set to be 0.7 × layoutwidth. Note that by default
layoutwidth and layoutheight will be equal to \paperwidth and \paperheight
respectively. Thus S(0,0) goes to S(0,1). See S(0,1).

13
 margin

if ratio P
P


specified B
body
BB BB
1 use marginratio  solvable

 forget body
S(0,1) S(1,1) S(2,1)

Figure 7: Specifications S(0,0) to S(2,1) and the completion rules (arrows). Column and
row numbers denote the number of explicitly specified lengths for margin and
body respectively. S(m,b) denote a specification with a set of the numbers
(margin, body) = (m, b).

S(0,1) Only body is specified, such as width=7in, lines=20, body={20cm,24cm}, scale=0.9

and so forth. Then geometry sets margins with the margin ratio. If the margin ratio is
not specified, the default is used. The default vertical margin ratio is defined as

top : bottom = 2 : 3 default. (8)

As for the horizontal margin ratio, the default value depends on whether the
document is onesided or twosided,

1:1 default for oneside,
left (inner) : right (outer) = (9)
2:3 default for twoside.
For example, if height=22cm is specified on A4 paper, geometry calculates top margin
as follows:
top = (layoutheight − height) × 2/5
(10)
= (29.7 − 22) × 2/5 = 3.08(cm)
Thus top margin and body height have been determined, the specification for the
vertical goes to S(1,1) and all the parameters can be solved.

S(1,0) Only one margin is specified, such as bottom=2cm, left=1in, top=3cm, and so forth.

• If the margin ratio is not specified, geometry sets body with the default
scale (= 0.7). For example, if top=2.4cm is specified, geometry sets
height = 0.7 × layoutheight (= 0.7\paperheight by default),
then S(1,0) goes to S(1,1), in which bottom is calculated with
layoutheight − (height + top) and results in 6.51cm on A4 paper if the layout
size is equal to the paper size.

• If the margin ratio is specified, such as hmarginratio={1:2}, vratio={3:4}

and so forth, geometry sets the other margin with the specified margin ratio. For
example, if a set of options “top=2.4cm,vratio={3:4}” is specified, geometry
sets bottom to be 3.2cm calculating
bottom = top/3 × 4 = 3.2cm
Thus S(1,0) goes to S(2,0).

Note that the version 4 or earlier used to set the other margin with the margin ratio.
In the version 5, therefore, with the same specification, the result will be different
from the one in the version 4. For example, if only top=2.4cm is specified, you got
bottom=2.4cm in the version 4 or earlier, but you will get bottom=6.51cm in the
version 5.

14
 S(2,1) The body and two margins are all specified, such as vdivide={1in,8in,1.5in},
“left=3cm,width=13cm,right=4cm” and so forth. Since geometry basically gives
priority to margins if dimensions are overspecified, geometry forgets and resets body.
For example, if you specify

\usepackage[a4paper,left=3cm,width=13cm,right=4cm]{geometry},

width is reset to be 14cm because the width of a A4 paper is 21cm long.

7 Changing layout mid-document

The version 5 provides the new commands \newgeometry{· · ·} and \restoregeometry, which allow
you to change page dimensions in the middle of the document. Unlike \geometry in the preamble,
\newgeometry is available only after \begin{document}, resets all the options ever specified except
for the papersize-related options: landscape, portrait, and paper size options (such as papersize,
paper=a4paper and so forth), which can’t be changed with \newgeometry.
The command \restoregeometry restores the page layout specified in the preamble (before
\begin{document}) with the options to \usepackage{geometry} and \geometry.
Note that both \newgeometry and \restoregeometry insert \clearpage where they are called.
Below is an example of changing layout mid-document. The layout L1 specified with hmargin=3cm
(left and right margins are 3cm long) is changed to L2 with left=3cm, right=1cm and bottom=0.1cm.
The layout L1 is restored with \restoregeometry.
\usepackage[hmargin=3cm]{geometry}
\begin{document}
Layout L1
\newgeometry{left=3cm,right=1cm,bottom=0.1cm}

Layout L2 (new)
\restoregeometry

Layout L1 (restored)
\newgeometry{margin=1cm,includefoot}

Layout L3 (new)
\end{document}

(saved) \newgeometry \restoregeometry \newgeometry

head head head

body rrr rrr body rrr body

body

foot foot
foot
foot
L1 L2 (new) L1 (restored) L3 (new)

A set of commands \savegeometry{hnamei} and \loadgeometry{hnamei} is handy if you want to

reuse more different layouts in your document. For example,
\usepackage[hmargin=3cm]{geometry}
\begin{document}
L1
\newgeometry{left=3cm,right=1cm,bottom=0.1cm}
\savegeometry{L2}
L2 (new, saved)

15
 \restoregeometry
L1 (restored)
\newgeometry{margin=1cm,includefoot}
L3 (new)
\loadgeometry{L2}
L2 (loaded)
\end{document}

8 Examples
1. A onesided page layout with the text area centered in the paper. The examples below have the
same result because the horizontal margin ratio is set 1:1 for oneside by default.
• centering
• marginratio=1:1
• vcentering
2. A twosided page layout with the inside offset for binding set to 1cm.
• twoside, bindingoffset=1cm
In this case, textwidth is shorter than that of the default twosided document by 0.7×1cm (= 0.7cm)
because the default width of body is set with scale=0.7, which means width = 0.7 × layoutwidth
(= 0.7\paperwidth by default).
3. A layout with the left, right, and top margin 3cm, 2cm and 2.5in respectively, with textheight of
40 lines, and with the head and foot of the page included in total body. The two examples below
have the same result.
• left=3cm, right=2cm, lines=40, top=2.5in, includeheadfoot
• hmargin={3cm,2cm}, tmargin=2.5in, lines=40, includeheadfoot
4. A layout with the height of total body 10in, the bottom margin 2cm, and the default width. The
top margin will be calculated automatically. Each solution below results in the same page layout.
• vdivide={*, 10in, 2cm}
• bmargin=2cm, height=10in
• bottom=2cm, textheight=10in
Note that dimensions for head and foot are excluded from height of total body. An additional
includefoot makes \footskip included in totalheight. Therefore, in the two cases below,
textheight in the former layout is shorter than the latter (with 10in exactly) by \footskip.
In other words, height = textheight + footskip when includefoot=true in this case.
• bmargin=2cm, height=10in, includefoot
• bottom=2cm, textheight=10in, includefoot
5. A layout with textwidth and textheight 90% of the paper and with body centered. Each solution
below results in the same page layout as long as layoutwidth and layoutheight are not modified
from the default.
• scale=0.9, centering
• text={.9\paperwidth,.9\paperheight}, ratio=1:1
• width=.9\paperwidth, vmargin=.05\paperheight, marginratio=1:1
• hdivide={*,0.9\paperwidth,*}, vdivide={*,0.9\paperheight,*} (as for onesided docu-
ments)
• margin={0.05\paperwidth,0.05\paperheight}
You can add heightrounded to avoid an “underfull vbox warning” like
Underfull \vbox (badness 10000) has occurred while \output is active.

16
 See Section 5.3 for the detailed description about heightrounded.
6. A layout with the width of marginal notes set to 3cm and included in the width of total body. The
following examples are the same.
• marginparwidth=3cm, includemp
• marginpar=3cm, ignoremp=false
7. A layout where body occupies the whole paper with A5 paper in landscape. The following examples
are the same.
• a5paper, landscape, scale=1.0
• landscape=TRUE, paper=a5paper, margin=0pt
8. A screen size layout appropriate for presentation with PC and video projector.

\documentclass{slide}
\usepackage[screen,margin=0.8in]{geometry}
...
\begin{slide}
...
\end{slide}

9. A layout with fonts and spaces both enlarged from A4 to A3. In the case below, the resulting paper
size is A3.
• a4paper, mag=1414.
If you want to have a layout with two times bigger fonts, but without changing paper size, you can
type
• letterpaper, mag=2000, truedimen.
You can add dvips option, that is useful to preview it with proper paper size by dviout or xdvi.
10. Changing the layout of the first page and leaving the others as default before loading geometry. Use
pass option, \newgeometry and \restoregeometry.

\documentclass{book}
\usepackage[pass]{geometry}
% ’pass’ disregards the package layout,
% so the original ’book’ layout is memorized here.
\begin{document}
\newgeometry{margin=1cm}% changes the first page dimensions.
Page 1
\restoregeometry % restores the original ’book’ layout.
Page 2 and more
\end{document}

11. A complex page layout.

\usepackage[a5paper, landscape, twocolumn, twoside,

left=2cm, hmarginratio=2:1, includemp, marginparwidth=43pt,
bottom=1cm, foot=.7cm, includefoot, textheight=11cm, heightrounded,
columnsep=1cm, dvips, verbose]{geometry}

Try typesetting it and checking out the result yourself. :-)

9 Known problems
• With mag 6= 1000 and truedimen, paperwidth and paperheight shown in verbose mode are dif-
ferent from the real size of the resulted PDF. The PDF itself is correct anyway.
• With mag 6= 1000, no truedimen and hyperref, hyperref should be loaded before geometry. Otherwise
the resulted PDF size will become wrong.
• With crop package and mag 6= 1000, center option of crop doesn’t work well.
