A4 in PDF, Canva, and Figma

A4 is the same physical size everywhere; only the working unit changes.

PDF print

210 x 297 mm

Set the document size to A4 (210 x 297 mm). Export with no scaling so the print driver does not shrink the page.

Canva

2480 x 3508 px

Choose Custom size and enter the 300 DPI pixel value. Canva works in pixels; 300 DPI matches print quality.

Figma

595 x 842 px

The A4 frame preset is 595 x 842 px at 72 DPI. For exact 300 DPI print, create a custom 2480 x 3508 px frame and export at 1x. Exporting the 72 DPI preset at 4x gives 2380 x 3368 px (~288 DPI, close to but not exact 300 DPI).

Formula

SizeKit uses a transparent rounding rule.

pixels = round((millimeters / 25.4) x DPI). Inches = millimeters / 25.4. Centimeters = millimeters / 10.
