The APA manual directs authors to use two spaces after a period (American Psychological Association, 2010, p. 88). However, as per a March 18th, 2014 tweet from @APA_Style, which is the official twitter account for the Publication Manual of the American Psychological Association (6th ed.), authors can use one or two spaces:

The tweet reflects what I've heard from most RRU instructors, which is that they aren't particularly concerned whether students use one or two spaces as long as the spacing is consistent. Accordingly, unless an editor or instructor has directed you specifically to use one or two spaces after closing punctuation, please use the approach that works best for you and be consistent. 


American Psychological Association [APA_Style]. (2014, March 18). @FMCatalano @craigbeebe @StacyLOliver APA allows either 1 or 2 spaces after a period; just be consistent. Everybody's happy [Tweet]. Retrieved from
