Ngeo Length Management

Nature Geoscience Length Management (ngeo-length-management)

When to trigger

• The main text is over the ~3,000-word Article limit (or you suspect it is)
• You have more than 4–6 display items or more than ~50 references
• You must decide what to cut, compress, or push to online Methods / SI
• A coauthor keeps adding regional detail and sensitivity tests
• Late stage: content, figures, and SI are stable and now must fit the container

How the Nature Geoscience length limits work

An Article is short and tightly bounded (verify current values on the author pages):

• Main text: up to ~3,000 words, excluding abstract, online Methods, references, and figure legends.
• Abstract: up to ~200 words, unreferenced.
• Title: up to ~90 characters.
• Display items: 4–6 figures and/or tables combined.
• References: typically up to ~50 in the main list.
• Brief Communication (the short format): ~1,000–1,500 words, ≤2 display items, ≤20 references, ~70-word abstract.

Unlike a deductible page budget, Nature counts these categories separately: text, display items, and references each have their own ceiling. The relief valves are the online Methods (excluded from the word count) and the Supplementary Information — the main text stays lean by pushing the reproducible and extended material outward.

Triage order (cut from cheapest loss to most painful)

1. Move protocol to online Methods first. Instrument detail, model configuration, statistical procedure, and the full uncertainty budget belong in Methods, which does not count against the 3,000-word main-text limit. This is usually the largest, lowest-pain saving (see ngeo-methods).
2. Move extended data to SI. Additional maps, full model ensembles, sensitivity sweeps, secondary proxies → Supplementary Information (see ngeo-supplementary).
3. Merge / cut display items. Combine related panels; move non-essential figures to SI to get within 4–6.
4. Prune references to the works that establish importance or are needed for trust; consolidate where Nature style permits, to stay near ~50.
5. Tighten prose (apply ngeo-writing-style): remove padding, hedging, regional-setting tours, and figure-transcribing sentences.
6. Cut scope as a last resort: demote a supporting result entirely.

Checklist

• Main text is within the ~3,000-word limit (excluding abstract/Methods/refs/legends)
• Abstract ≤ ~200 words, unreferenced; title ≤ ~90 characters
• Display items within the 4–6 ceiling
• References near / under the ~50 cap, pruned to essentials
• Reproducible protocol and full uncertainty budget are in online Methods, not the main text
• Extended data and sensitivity tests are in SI
• Prose padding, hedging, and regional tours removed (cross-check ngeo-writing-style)
• The main text still stands alone after trimming (cross-check ngeo-supplementary)

Anti-patterns

• Counting only words and being surprised the display-item or reference ceiling is blown
• Trimming load-bearing content (the decisive evidence, the headline uncertainty) to fit
• Padding online Methods or SI until the main text no longer stands alone
• Leaving instrument/model detail in the main text that belongs in (excluded) Methods
• Keeping a seventh decorative figure over the 4–6 ceiling
• Discovering the over-length only at submission, after content is frozen

Output format

【Main text vs. ~3,000】over by ~X words (verify current limit)
【Abstract / title within limits】yes / fix
【Display items】N (≤6) — merge/move list
【References】N vs. ~50 — prune list
【Moved to online Methods】list (excluded from word count)
【Moved to SI】list
【Still stands alone】yes / fix
【Next】ngeo-cover-letter or ngeo-submission

The word/display-item/reference limits and content-type definitions are exactly the kind of volatile specifics that change — always verify current limits on the official Nature Geoscience author pages (Checked: 2026-07-16).
