Design is a plan of creating an idea through a combination of texts, images, and other
elements that are placed together artistically, whereas, the layout is a term used as the
process of organizing and arranging these elements in a design as you plot it in a paper.
1. Balance
It refers to the proper arrangement of the elements, which gives a visual
weight for the design. There are two types of balance, Symmetrical or
Asymmetrical. Symmetrical balance is where the elements are equally distributed
on both sides of your design, technically a mirror-based design. In contrast,
Asymmetrical balance is a free layout where the elements can be placed in any
order or the opposite of symmetrical.
2. Emphasis
It refers to something that needs to stand-out or emphasize. When working
on emphasis, you can change the color, size, or even the element itself to lead the
eye to the focal interest.
3. Pattern, Repetition and Rhythm
The use of repetitive elements such as lines, shapes, forms, textures, space,
colors, font, style, and the like to create texture, movement, continuity, and
consistency of the design. It also makes the design formal and more comfortable
to read because of its uniformity.
4. Alignment
It refers to the proper placement of an element to your design, just like
invisibly placing or aligning your texts or images diagonally, vertically, and
horizontally. The standard texts or paragraph alignment we apply are center, right,
left, and justified.
5. Hierarchy
It refers to the proper arrangement of the details such as text, characters,
numbers, and symbols. Changing its character size, thickness, spaces, or even font
type to stand out is its most critical features. By applying this principle, it can help
the viewer to recognize and navigate the highlight of the event smoothly.
6. Contrast
It refers to the use of different or opposite elements such as sizes (large or
small), shapes (geometric or organic), spaces (negative or positive), form (real or
abstract), colors (monochromatic, complementary, triadic, tetradic), texture
(smooth or rough), and values (light or dark). The contrast gives visual weight to
an object or design. You must consider and limit the use of different elements,
color, style, and typography to avoid cluttered design. When creating contrast in
color and text, it is advised to choose a color from the background to create
consistency of your design. Always remember that the details must be readable by
having a dark-light value of either text and background or vice-versa.
7. Unity and Harmony
It refers to the relationship of the elements or the contents when you place
them together. The elements of the design must work together and agree to its
meaning, theme, feeling, or mood.
