Guidelines for Calculating Length - Physical Review X and Reviews of Modern Physics

These simple guidelines are used to determine the lengths of articles in Physical Review X (PRX) and Reviews of Modern Physics (RMP). This method is a simplification of the scheme for Guidelines for Calculating Length used for Letters and short papers.

For PRX, this procedure is applied to the accepted version of the manuscript and the appropriate charges are calculated based on this estimate. The base charge is $1500 for articles less than 20,000 words or word equivalent (roughly 20 composed pages). Longer articles will incur additional charges, $30 for every 1000 word increment over 20,000.

WORD COUNT PROCEDURE

Text

Include:

• Any text in the body of the article
• Any text in a figure caption or table caption
• Any text in a footnote or an endnote

Exclude:

• Title
• Author and affiliation listing
• Abstract
• Receipt date, published date, and other publication history
• PACS or Keywords and DOI
• References
• Author byline footnotes
• Acknowledgments

Displayed Math

The word equivalent for displayed math is 16 words per row for single-column equations. Two-column equations count as 32 words per row.

Figures

The word equivalent for figures is 170 words per figure for single-column figures. Two-column figures count as 340 words per figure.

Tables

The word equivalent for tables is 13 words plus 6.5 words per line for single-column tables. Two-column tables count as 26 words plus 13 words per line.

Total Word Count = Text count + Displayed math + Figures + Tables
