Flexible Article Length

A standard regular research report submitted to PNAS is 6 pages, or approximately 4,000 words, 50 references, and 4 medium-size graphical elements (i.e., figures and tables). The preferred length of articles remains at 6 pages, but PNAS allows articles up to a maximum of 12 pages as of July 1. See the PNAS Author Center for additional details on manuscript length and publication fees.

All authors may be named in the citations for initial submissions. For revisions or final submissions, if there are more than five authors, list the first author's name followed by et al.
