Advanced Materials Length Management (advmat-length-management)

When to trigger

• You are unsure whether the work is a Communication or a full Research Article
• The manuscript overruns the typeset page limit for its article type
• Figures/schemes are large and you must trade display items against text
• A reviewer or editor asked you to condense to a Communication, or expand to an Article
• You are in late polish, after the science and figures are stable

Article type sets the budget

Advanced Materials counts length in typeset published pages, not manuscript pages — a double-spaced 25-page manuscript may typeset to far fewer pages in the two-column layout. Word count and display items (figures, schemes, tables) count together against the page budget. Approximate targets (verify current limits on the author page):

Article type	Typeset budget (approx.)	Abstract	Display items (approx.)
Communication	~4 published pages (~3500 words)	none — opening paragraph acts as abstract	~4 figures/tables
Research Article	~10 published pages (~3000–8000 words)	short abstract (~200 words) + 3–7 keywords	~3–8 display items
Review / Progress	longer, by invitation/agreement	structured per type	many

A large or multi-panel figure consumes a disproportionate slice of the page budget: adding a panel can cost a paragraph of text.

Choosing Communication vs. Article

• Communication — one sharp, urgent advance that a specialist audience needs now; concise, high-impact, no room for exhaustive characterization in the body (it goes to the SI).
• Research Article — the same class of advance but requiring the full structure → property → function story, multiple device configurations, or a mechanism study that a Communication cannot hold.
• If your "Communication" needs eight figures to be believed, it is an Article. If your "Article" has one figure and one claim, it is a Communication.

Trimming order (cut in this sequence)

Trim only after the central advance, characterization, and figures are stable, so you cut padding, not evidence:

1. Hype and boilerplate — delete "novel/unprecedented/facile/remarkable"; collapse background paragraphs to one sentence (see advmat-writing-style).
2. Redundant prose — remove sentences that transcribe figure values; interpret instead.
3. Optimization and secondary data — move process sweeps, extra samples, and control experiments to the SI (see advmat-supplementary).
4. Display items — merge panels that prove one link; move non-essential figures to the SI; avoid double-column figures unless the data demand it.
5. Reference pruning — keep the citations that establish novelty and support trust; drop padding.

Never trim: the decisive characterization, the benchmarking, or the headline metric's statistics.

Fit-check routine

• Typeset a draft in the Wiley template to see real page count, not manuscript pages.
• Budget each figure by its printed area; tally figures + text together.
• Leave a margin under the limit so revision additions do not overrun.
• If still over after trimming padding, the honest fixes are: promote to a Research Article, or move a supporting result wholesale to the SI — not shrinking fonts or figures below legibility.

Checklist

• Article type chosen deliberately (Communication vs. Research Article) and matches the content
• Length measured as typeset pages in the Wiley template, not manuscript pages
• Display items counted together with text against the budget
• Hype words and background padding removed first
• Optimization/secondary data moved to the SI, not deleted
• No double-column figure unless the data require it
• Abstract/keywords conform to the article type
• Decisive characterization, benchmarking, and statistics untouched

Anti-patterns

• Trimming characterization or benchmarking to hit the page limit
• Counting manuscript pages instead of typeset pages and being surprised at proof
• Shrinking figures below legibility to save space
• Forcing a full study into a Communication by hiding the evidence in the SI
• Padding a thin Communication into an Article with filler characterization
• Discovering the overrun only at production, after acceptance

Output format

【Article type】Communication / Research Article — matches content?  yes / reconsider
【Typeset page estimate】within budget?  yes / over by ~X
【Display items】counted with text?  N figures + M tables
【Trim done】hype / prose / secondary-data-to-SI / figures / refs
【Untouched】characterization + benchmarking + statistics intact?  yes
【Next】advmat-cover-letter or advmat-submission

Page limits, word counts, abstract/keyword rules, and display-item allowances differ by article type and change — verify all on the official Wiley Advanced Materials author page.
