Choose Your Line Spacing: From the drop-down menu, you can select from several preset spacing options like 1.0 (single), 1.15, 1.5 (one and a half), or 2.0 (double). Click on the one you need.

Single space between sentences. The question of whether to put one space or two after a period or other terminal punctuation mark is hotly debated and highly controversial. That’s ridiculous.
