mm to pixels converter

Type a length in millimetres, centimetres, inches or pixels and pick a resolution: the converter shows the same length in every unit. Pixels = mm x DPI / 25.4, so 35 mm at 300 DPI is 413 px.

One inch is 25.4 mm, so pixels = mm x DPI / 25.4. Pixels are rounded to the nearest whole pixel.

How it works

  1. Enter the length and its unit.
  2. Choose the DPI: 300 and 600 are the print resolutions authorities state in our dataset.
  3. Read the length in every unit; pixels are rounded to whole pixels.
