Editors and production teams look at hundreds of graphical abstracts. The same problems come up again and again, and most are easy to avoid once you know them. Fix these and your figure sails through.
1. Trying to summarise the whole paper
A graphical abstract shows one key finding, not your methods, results, and discussion. If it has more than a handful of elements, cut. Fix: write the single take-home message first, then illustrate only that.
2. Text too small to read as a thumbnail
The abstract appears tiny in the table of contents. Fix: shrink your design to thumbnail size on screen — if any label is unreadable, enlarge it or remove it.
3. Wrong dimensions or resolution
Submitting the wrong size or under 300 dpi is an instant bounce. Fix: design to the journal's exact spec and export correctly — see our size guide.
4. Copyrighted or mismatched icons
Borrowed clip art creates legal risk and a patchwork look. Fix: use one consistent, openly licensed icon set or make your own — see image licensing for figures.
5. No clear flow
Elements scattered without direction confuse readers. Fix: establish a left-to-right or top-to-bottom flow with consistent arrows.
6. Clashing or inaccessible colours
Too many colours, or a palette that fails for colourblind readers, undermines clarity. Fix: three to four colours from a colourblind-safe palette (guide here).
7. Overselling the result
A graphical abstract that implies more than the data support is a credibility risk. Fix: keep it honest — it should match your actual conclusion exactly.
Quick test before you submit: can a non-specialist understand your main finding from the thumbnail alone, in under ten seconds?
