.APA Style (7th ed.)
The APA manual directs authors to use one space after a period (American Psychological Association, 2020, p. 154). Unless an editor or instructor has directed you specifically to use two spaces after closing punctuation, please insert a single space after end punctuation marks in sentences, such as periods, question marks, or exclamation marks.
