Pixels

Use pixels for screens, social posts, and websites. Type a width and the height follows if the ratio is locked. Unlock the ratio if you need a stretch.

Centimeters and DPI

Use centimeters when you care about print size. The tool converts cm to pixels with the DPI you choose: pixels = cm ÷ 2.54 × DPI. 10 × 15 cm at 300 DPI is 1181 × 1772 pixels.
