Frontiers requirements vary considerably by journal. There is no single size that fits every Frontiers title, but the common baseline is a square-ish figure at 300 DPI in RGB, saved as PNG or JPEG, under 20 MB. Always check your specific Frontiers journal's author guidelines — start from the Frontiers author guidelines — before you build the figure.
| Requirement | Frontiers value |
|---|---|
| Fixed size | No — varies by journal (often square) |
| Resolution | 300 DPI recommended |
| Color space | RGB |
| File formats | PNG or JPEG |
| File size | Under 20 MB |
| Text | Legible at final display size |
Frontiers journals differ enough that the safest move is to open your target journal's author guidelines and confirm the exact requirement rather than assume a universal size.
Since the spec shifts by title, build a figure that satisfies the common denominators:
If you'd rather generate the figure than draw it, you can build it from your paper. With Graphab the flow is:
The journal page shows how the Frontiers graphical abstract requirements translate to an export. Graphab exports as TIFF or PNG; PNG is the format most Frontiers journals expect.
For Frontiers, there's no universal graphical abstract size — target a clean, square-ish figure at 300 DPI in RGB as PNG or JPEG, under 20 MB, and confirm your specific journal's rules in the Frontiers author guidelines. If you want a fast route, Graphab turns your abstract or sketch into a compliant figure in a few minutes.
Paste your paper abstract and Graphab drafts a publication-ready figure, sized for your target journal.
