Journal Submission Specifications: Word Limits, Figure Limits & Reference Caps
Journal submission requirements by journal vary much more than most authors expect, from NEJM's strict 3,000-word cap and 35-reference limit to PLOS ONE and eLife with no hard limits at all. This reference page replaces scattered author-instructions tabs with one searchable comparison table.
This table covers 33 journals. Word counts are for the main text unless otherwise noted and typically exclude abstract, methods, references, and figure legends, but definitions vary by journal. Always verify against current author instructions before submission.
Quick orientation
Use this page when the journal shortlist is set and the question is whether the package fits the format constraints.
Search, sort, and export submission limits across 33 journals, including word limits, abstract format, figure allowances, reference caps, and supplementary-material rules.
Important note
These are working reference values based on published author instructions as of early 2026. Always verify what the journal counts in the word limit and confirm current figure and reference limits on the live author-instructions page before submission.

Patterns worth knowing
Patterns worth knowing
Submission specs are not arbitrary trivia. They often reveal what kind of paper the journal expects and how much narrative or evidentiary compression the editors assume.
The 3,000-word club
The most prestigious clinical journals (NEJM, Lancet, JAMA, BMJ) are also some of the most restrictive on word count. Their 3,000-word limit covers the body text only; methods, abstract, references, and figure legends sit on top. The practical ceiling for a submission-ready manuscript to these journals is closer to 7,000–8,000 words total.
Cell Press vs. Nature: different philosophies
Cell Press journals (Cell, Neuron, Immunity, Cancer Cell) allow 6,000–8,000 word articles with extensive supplementary data: they expect full mechanistic stories. Nature family journals (Nature, Nature Medicine, Nature Genetics) cap main text at around 3,000 words but allow extensive supplements. Same prestige tier, opposite length philosophy.
Reference limits matter most at clinical journals
JAMA's 35-reference limit is strict and enforced. NEJM allows 70. Many basic science journals (PNAS, Genome Biology, eLife) have no limit. If you're coming from a basic science background and submitting to a clinical journal for the first time, the reference cap is the adjustment that catches most authors off guard.
Open-access journals are generally more flexible
PLOS ONE, eLife, Scientific Reports, BMJ Open, and BMC Medicine don't impose strict word or figure limits. This isn't lower standards. It's a different philosophy. The page cost concern that drove strict limits at traditional print journals simply doesn't apply when publication is digital and costs are covered by APCs.

Frequently asked questions
Frequently asked questions
What word count limits apply to original research articles at top journals?
Word count limits vary considerably. Nature limits original research articles to 3,000 words of main text. Science allows 4,500 words. Cell allows 6,000-8,000 words depending on article type. NEJM original articles are capped at 3,400 words. JAMA research articles allow 3,000 words. Nature Communications and Scientific Reports are more permissive at 5,000-8,000 words. Always check the current author instructions for your specific article type - Brief Communications, Letters, and Short Reports have tighter limits than full Research Articles.
How many figures and tables are typically allowed?
Most top journals limit main-text figures to 5-6 for Letters or Brief Communications and 6-8 for full Research Articles. Nature allows 5 figures or tables in the main text; additional data can go in Extended Data (up to 10 items). Cell allows 7 figures. NEJM typically allows 4-5 tables or figures in the main text. Additional figures and tables belong in Supplementary Information. Reviewers and editors pay close attention to whether main-text figures are all essential - unnecessary figures are a common revision target.
What file formats do journals accept for manuscript and figure submission?
Most journals accept manuscripts in Microsoft Word (.docx) or LaTeX format via submission systems like Editorial Manager or ScholarOne. For figures, high-resolution TIFF (300-600 DPI for photographs, 600-1200 DPI for line art) is the most widely accepted format. PDF and EPS are also commonly accepted. Avoid low-resolution figures - they are a common cause of revision requests. For revision submissions, many journals also accept a tracked-changes Word document alongside the clean version.
Ready to apply this to a real draft?
Move from reference guidance to a manuscript-specific check
Use the public submission-readiness path when you already have a manuscript and need a draft-specific signal, not just a general guide.
Best for researchers who want a fast readiness read before deciding whether to revise, retarget, or submit.
