How many spaces should you put between sentences?
One.
The Chicago Manual of Style, the AP Stylebook, and the Modern Language Association all recommend using one space after a period at the end of a sentence. two spaces at the end of a sentence is a carryover from the days of typewriters with monospaced typefaces. Two spaces, it was believed, made it easier to see where one sentence ended and the next began. Most typeset text, both before and after the typewriter, used a single space. Digital typefaces are more proportionally spaced.
