Conversion is exact math (mm ÷ 25.4 × DPI) — print driver scaling and bleed margins are separate concerns. DPI 1–2,400, dimensions up to 10,000 mm / 100,000 px.

How to use

  1. Pick a size or enter custom mm.
  2. Choose the DPI.
  3. Read the pixel dimensions — or reverse the direction.

What it supports

A/B (JIS), Letter/Legal/Tabloid, postcard, business card, L-size photo, and custom sizes; 1–2400 DPI. Print scaling and bleed are separate from this conversion.
