1. Quick-Reference Table
| Journal | Min DPI | Formats | Fonts | Single Col | Double Col |
|---|---|---|---|---|---|
| Nature | 300 | TIFF, EPS, PDF | Arial, Helvetica | 89 mm | 183 mm |
| Science | 300 | EPS, PDF, AI | Helvetica, Arial | 85 mm | 174 mm |
| Cell | 300 | TIFF, EPS, PDF | Arial, Helvetica | 85 mm | 174 mm |
| PLOS ONE | 300 | TIFF, EPS | Arial | 83 mm | 173 mm |
| IEEE | 300 | TIFF, EPS, PDF | Times New Roman | 88 mm | 181 mm |
| ACS | 300 | TIFF, EPS | Arial, Helvetica | 84 mm | 175 mm |
| Elsevier | 300 | TIFF, EPS, PDF | Arial, Helvetica | 90 mm | 190 mm |
| Springer | 300 | TIFF, EPS | Arial | 84 mm | 174 mm |

300 DPI
Photographs, continuous tone
600 DPI
Line art, graphs, charts
1200 DPI
Fine line art, thin lines
Common Mistake
Upsampling a 96 DPI image to 300 DPI does not add detail - it just makes the file bigger with blurry pixels. Always generate figures at the target DPI from the start.
3. File Format Rules
TIFF (LZW)
+ Universally accepted, lossless compression
- Large file sizes (10-50 MB)
EPS / PDF
+ Vector = infinite resolution for line art
- Not all journals accept PDF
PNG
+ Small files, lossless, web-friendly
- Some journals reject (use TIFF instead)
JPEG
+ Small file size
- Lossy compression introduces artifacts - avoid for data figures
4. Font and Sizing
Arial or Helvetica (sans-serif). Never use decorative or serif fonts in figures.
6 pt after scaling. Most journals require 7-8 pt for legibility.
8-10 pt bold. Must be readable at final print size.
10-12 pt bold, lowercase (a, b, c) or uppercase (A, B, C) per journal style.
Usually NOT on the figure - goes in the caption instead.
5. Color and Accessibility
Colorblind-safe
Use palettes like viridis, cividis, or Wong palette. Avoid red-green only distinctions.
Grayscale test
Print your figure in B&W. If you can't distinguish groups, add patterns or markers.
Color charges
Some journals charge $500+ for color. Provide a grayscale alternative.
Contrast ratio
Minimum 4.5:1 contrast ratio for text against backgrounds (WCAG AA).
