Formula

How to calculate this size

Pixel formulapixels = millimeters / 25.4 x PPI

420 mm x 300 PPI = 4,961 px wide.

Trim result4,961 x 7,016 px

Use this when the artwork stops at the finished edge.

Bleed result5,031 x 7,087 px

Add 3 mm per side before calculating pixels when artwork reaches the edge.

Common mistakes

Avoid these a2 paper size problems

Mixing screen pixels with print quality

A paper size needs a PPI target before pixels mean anything for print.

Forgetting orientation

Portrait and landscape use the same dimensions, but width and height swap in the export.

Adding bleed to a paper reference

Paper pages show trim size first; add bleed only when the design prints to the edge.

Workflow

Use A2 Paper Size in a finished file

Confirm the physical size

Copy the millimeter, centimeter, or inch dimensions for the selected paper standard.

Choose PPI

Use 300 PPI for most sharp print exports, or match the printer requirement.

Calculate pixels

Multiply inches by PPI, then add bleed only when artwork reaches the trimmed edge.
