Physical Review Letters Submission Guide: Requirements, Formatting and What Editors Want

PRL publishes one type of paper: Letters. The core text (abstract through Acknowledgments) is limited to 4 pages in REVTeX two-column format, typically 3,000-3,500 words before figures consume page space.

End Matter is a newer PRL feature that lets you add up to 2 pages of appendices after the references. This content is fully peer-reviewed and copyedited but doesn't count against the 4-page core limit. Use End Matter for derivations and technical details that specialists need but that would interrupt the flow for general readers. Content that isn't essential for either audience should go in Supplemental Material instead.

Supplemental Material can be any length and is published online. Reviewers read it, so it needs to be well-organized.

What PRL does not publish: review articles, comments on previously published papers (those go to Physical Review journals as Comments), and papers too specialized for a broad physics audience.

PRL now requires two separate editorial communications. The 100-word justification statement is entered directly in the submission system and goes to the divisional editor who makes the desk decision. Use it to state your main result, identify the audience, and make the case for publication in one tight paragraph.

The cover letter is a separate document. About 35% of submissions get desk-rejected, and the cover letter is your chance to prevent that. Three things it must do:

• State the result clearly. Not "we studied X" but "we demonstrate for the first time that X exhibits Y, which contradicts the prediction of Z."

• Explain broad significance. If you're submitting a condensed matter paper, explain why a particle physicist should care. Too-specialized scope is the single most common reason for desk rejection.

• Identify the subfield. Tell the editor which PRL subject area your paper fits (condensed matter, high energy physics, atomic and molecular physics, etc.). This routes your paper to the right editor.

Don't include reviewer suggestions in the cover letter, the submission system has a separate field.

REVTeX 4.2 is PRL's required LaTeX document class. Download it from the APS website or use it through Overleaf (which has a PRL template). The document class handles all formatting: column width, font sizes, reference style, equation numbering.

Key formatting rules:

Figures. Must be publication-quality (300+ dpi for raster, vector preferred). PRL uses two-column format, so figures can be single-column (3.4 inches wide) or double-column (7 inches wide). Color figures are free.

Equations. Number all displayed equations. Use standard notation consistent with APS style.

References. Use BibTeX with the apsrev4-2 style file. PRL's reference format is specific, and using the correct BibTeX style eliminates formatting issues. Cite journal articles with authors, title, journal, volume, page, and year.

Title. Keep it descriptive but concise. PRL titles tend to be short and specific. Avoid colons and subtitles unless absolutely necessary.

Abstract. PRL abstracts should be one paragraph, under 600 words, and self-contained. State the key result and its significance. Don't include references in the abstract.

Exceeding the page limit. Check your compiled PDF before submitting. If you're at 4.1 pages, you need to cut, shrinking fonts or margins is not allowed. Remember that End Matter gives you 2 extra pages for technical content, so move derivations there before cutting substance.

Using the wrong document class. Papers submitted in standard article class, JHEP format, or any non-REVTeX template get returned immediately without review.

Low-quality figures. Export at 300+ dpi or use vector formats (PDF, EPS). Screen-resolution exports from Mathematica or matplotlib look terrible in print.

Missing PhySH codes. PRL uses the Physics Subject Headings (PhySH) classification system. Select appropriate codes during submission, this routes your paper to the right editor and reviewers.

PRL divisional editors are active researchers evaluating four things:

1. New results that shift understanding. The result must change how physicists think about something, open a new direction, or resolve a long-standing question. Incremental advances don't clear the bar.
2. Broad interest. The paper must appeal to physicists outside your immediate subfield, not dumbed down, but framed to connect with broader physics questions.
3. Concise writing. Four pages forces clarity. Get to the result fast, present it without unnecessary qualification, use space efficiently.
4. Solid methodology. Experimental papers need clear setup descriptions, error analysis, and controls. Theoretical papers need mathematical rigor and connection to observable quantities.

Data Availability Statement (DAS). Now mandatory for all PRL papers. The submission system generates the DAS based on your answers to questions during submission, this is a change from previous APS policy.

Conflicts of interest. Declare any conflicts during submission, including financial relationships and institutional affiliations.

Prior publication. PRL does not accept papers published elsewhere. arXiv preprints are not considered prior publication.

Submit if:

• Your result has broad physics significance beyond your specialty community
• The finding changes understanding, opens a new direction, or resolves a long-standing question
• Your paper fits the 4-page core limit (plus End Matter) with publication-quality figures
• You can frame the broad appeal convincingly in the justification statement and cover letter

Think twice if:

• Your audience is concentrated in one subfield, Physical Review B, A, or C may be the natural home
• The result incrementally extends established findings without a conceptual challenge
• Your manuscript needs extensive technical buildup before the significance becomes clear

1. End Matter changes your space budget. The newer End Matter option gives you up to 2 pages after references for appendices and derivations. Use this to keep the core Letter tight while still including specialist-level detail. Content that doesn't earn End Matter status goes in Supplemental Material.
2. The 100-word justification is a separate editorial tool. This isn't the cover letter. It's a direct pitch to the divisional editor about why PRL specifically should publish your result. Write it as a self-contained argument.
3. The 3,750-word limit is enforced strictly. PRL counts words including figure captions and references. Most authors underestimate because they don't count captions.
4. Referees are specialists, not generalists. Unlike Nature or Science, PRL reviewers work in your exact subfield. You don't need to explain basic concepts, but you must explain why your result differs from the last 3-5 papers in the area.
5. Resubmission is common. PRL rejects about 70% of initial submissions but has a well-established resubmission process. A thoughtful rebuttal with additional data can reverse an initial rejection.

PRL's word limit is a filter. Papers that can't make their case concisely usually don't belong here. Typical allocation for accepted Letters: abstract ~150 words, introduction ~500 words (frame the problem, cite 8-12 references, state what's new), methods ~500 words (enough for a specialist; full derivations go in End Matter or Supplemental Material), results ~1,500 words (the core, 40% of your budget), discussion ~800 words, conclusions ~200 words.

Plan for 3-4 figures consuming about one page. Single-column figures are more space-efficient than double-column. Every figure that doesn't directly support the central result should move to Supplemental Material.

A PRL structure check can assess whether the abstract, introduction, and word allocation match PRL's format expectations before you submit.

The five comments that appear most frequently in PRL referee reports:

1. "The comparison to prior work is insufficient." Add a paragraph in the introduction explicitly contrasting your result with the last 3-5 papers in the area, citing specific papers.
2. "The error analysis is incomplete." Include systematic and statistical errors separately, show error propagation, and acknowledge large error bars honestly.
3. "The paper is too long." Move derivations to End Matter, secondary results to Supplemental Material. Cut the introduction to under 500 words.
4. "The significance is not clearly stated." State the advance explicitly in the introduction's final paragraph: "This is the first demonstration of X" or "This resolves the tension between Y and Z."
5. "The supplemental material is thin." Referees read the Supplemental Material. Include full derivations, additional data, control experiments, and extended error analysis.

The pattern: PRL referees want concise main text with thorough supplements, precise positioning against prior work, and honest error analysis.

In our pre-submission review work with manuscripts targeting Physical Review Letters, three patterns generate the most consistent desk rejections and revision requests.

In our experience, roughly 35% of desk rejections at Physical Review Letters trace to scope or framing problems that prevent the paper from competing in this venue. In our experience, roughly 25% involve insufficient methodological rigor or missing validation evidence. In our experience, roughly 20% arise from a novelty claim that outpaces the supporting data.

• Cover letter states what was studied, not what was demonstrated. PRL's 100-word justification statement and cover letter must both state the specific result in declarative terms. The journal's own guidance is explicit: not "we studied X" but "we demonstrate for the first time that X exhibits Y, which contradicts the prediction of Z." Authors who frame their cover letter around motivation and method rather than the specific demonstrated result give divisional editors no basis for evaluating significance. Desk rejections arrive within a week when the letter does not commit to a specific new result.

• Compiled PDF not verified against the 4-page core limit before submission. The 4-page limit applies to the compiled REVTeX two-column PDF, not the source word count. Figure placement in two-column format is controlled by LaTeX compilation, not the author's draft. Papers at 3,500 words with three double-column figures often compile to 4.2 pages. The APS submission system checks page count, and papers that exceed the limit are returned without review. Authors must compile and measure the output PDF before submission, not estimate from the word count alone.

• Supplemental Material is thin or absent. PRL referees evaluate Supplemental Material as part of peer review, not as optional context. The most common PRL referee criticisms include explicit requests for full derivations, additional data, control experiments, and extended error analysis in the Supplemental Material. Authors who treat Supplemental Material as secondary frequently receive major revision requests that require months of additional work. A comprehensive Supplemental Material is not optional at PRL: reviewers will ask for it if it is missing.

SciRev author-reported review times provide additional community benchmarks when planning your submission timeline.

A PRL submission requirements check can verify whether the cover letter argument, compiled page count, and Supplemental Material meet PRL's requirements before you submit.

Editors consistently screen submissions against these patterns before sending to peer review, so addressing them before upload reduces desk-rejection risk.
