A4 size in pixels, and how to resize to it

A4 is a physical paper size, 210 × 297 mm (8.27 × 11.69 in). There is no single pixel size for it, because pixels depend on the resolution (DPI) you print or display at. What a printer or an upload form actually reads is the pixel count, so the trick is to set the right number of pixels for the resolution you need. A4 in pixels at common resolutions: • 300 DPI (print quality): 2480 × 3508 px • 150 DPI (draft / lighter file): 1240 × 1754 px • 72 DPI (on-screen): 595 × 842 px • 600 DPI (fine print): 4961 × 7016 px This page sets those exact pixels. At 300 DPI, 2480 × 3508 px prints at true A4 size. A note on shape: A4 is quite tall (a 1:1.414 ratio), so if your image is a different shape, choose "Fit" to keep the whole image with white margins (best for documents and logos), or "Fill" to crop it so it covers the full page edge to edge (best for a photo poster). Switch between portrait and landscape with the quick sizes.
