PLOS ONE Graphical Abstract Guidelines: Size, DPI & Format

TL;DR

PLOS ONE does not require a graphical abstract and does not specify fixed dimensions for one. If you choose to include a visual summary, follow PLOS ONE's general figure rules: 300 DPI minimum, RGB, saved as TIFF, EPS, or high-quality PNG, under 10 MB, with text legible at final size (aim for at least 8 pt). Always confirm the current spec in the PLOS ONE submission guidelines.

PLOS ONE graphical abstract specs at a glance

Requirement	PLOS ONE value
Required?	No — optional visual summary
Fixed size	Not specified — follow figure guidelines
Resolution	300 DPI minimum
Color space	RGB
File formats	TIFF, EPS, or high-quality PNG
File size	Under 10 MB

PLOS ONE publishes detailed figure requirements rather than a dedicated graphical abstract spec, so treat these as the working rules for any summary image and check the live guidelines for updates.

Before you submit — AI use has to be disclosed. As of 2026-07-30, PLOS ONE's editorial policy carried no blanket ban on AI-generated figures, but required you to disclose any AI use (in the Methods or acknowledgements) and held you fully responsible for the figure's accuracy. Publisher policies change and differ between journals, so read your target journal's current policy page yourself. Until you have done that, treat an AI draft as a planning and sizing aid, and verify every element against your results.

What works for a PLOS ONE visual summary

Because there's no mandated format, the goal is a clean, self-explanatory figure that follows PLOS ONE's figure standards:

• One clear takeaway. Summarize the main finding in a single image.
• Readable text. Keep labels short and at least 8 pt in the final figure.
• Meet the figure rules. 300 DPI, RGB, and a supported file type (TIFF, EPS, or PNG).
• Keep it under the size cap. Stay below the 10 MB file limit.

How Abfig helps you make a PLOS ONE visual summary

If you'd rather not build it manually, you can generate the figure from your paper. With Abfig the flow is:

1. Paste your abstract — optionally let the AI condense it into a tight visual brief — or upload a rough sketch.
2. Generate the figure. Abfig's AI produces a clean summary image.
3. Export at 300 DPI. Export as TIFF or PNG at submission resolution so it meets PLOS ONE's figure rules.

You can see how the PLOS ONE graphical abstract requirements map to a real export on the journal page. Abfig exports at submission resolution as TIFF or PNG — both accepted by PLOS ONE.

Common mistakes to avoid

• Assuming it's required. PLOS ONE doesn't mandate a graphical abstract — don't hold up your submission over one.
• Low resolution. A web-quality image will fail the 300 DPI figure check.
• Oversized files. Keep the file under 10 MB.
• Tiny text. Labels below ~8 pt become unreadable once the figure is scaled.

Conclusion

PLOS ONE treats a graphical abstract as an optional visual summary with no fixed size — just meet the standard figure rules (300 DPI, RGB, TIFF/EPS/PNG, under 10 MB) and confirm the live PLOS ONE submission guidelines. If you want one anyway, Abfig turns your abstract or sketch into a journal-sized visual summary in a few minutes — just disclose the AI use when you submit.
