Every publisher sets its own rules for graphical abstracts, and they update them periodically. Treat the figures below as a starting point, then confirm the current numbers in the journal's own author guidelines before you export — specs genuinely do change between submission systems and journal families.
Why exact dimensions matter
A graphical abstract is displayed at a fixed size in the online table of contents and in search listings. If you design at the wrong aspect ratio, the production team either crops it (cutting off your labels) or rescales it (making text fuzzy). Designing to spec keeps you in control of how your work looks.
Commonly requested specifications
These are widely cited ranges across major publishers. Use them to plan, but always check the live guidelines.
| Publisher family | Typical format | Resolution |
|---|---|---|
| Elsevier | Landscape, roughly square-ish; minimum size around 531 × 1328 px, sized for on-screen display | 300 dpi min for raster |
| Nature Portfolio | Often square; supplied with the submission per journal instructions | 300 dpi+ |
| ACS | TOC graphic, landscape (about 3.25 × 1.75 in) | 300 dpi+ |
| RSC | TOC entry, roughly 8 × 4 cm landscape | 300 dpi+ |
| Wiley | Square or landscape depending on journal | 300 dpi+ |
Rule of thumb: design at the largest size the journal allows, in vector where possible, and you can always scale down cleanly.
Resolution and file format
- Raster images (TIFF, PNG, JPEG): aim for 300 dpi minimum at final print size; 600 dpi for line art and text.
- Vector (EPS, PDF, AI): preferred where accepted because it scales without quality loss.
- Colour mode: RGB for online-only abstracts; CMYK only if the journal prints them.
Typography rules most people miss
Publishers frequently specify a minimum font size (often around 5–8 pt at final size) and a preferred typeface (commonly a clean sans-serif). Because the abstract is shown small, oversized clear labels always beat dense paragraphs. Never embed an entire sentence of the abstract as an image caption.
A universal pre-submission checklist
- Dimensions match the author guidelines exactly.
- Resolution is 300 dpi or higher (600 for text/line art).
- Single, clear take-home message — readable as a thumbnail.
- Colourblind-safe palette and consistent stroke weights.
- No copyrighted icons or images without permission.
- File format and colour mode match the spec.
- All abbreviations are either defined or avoided.
