Canada passport photo size & rules
Canada uses a distinctive tall format that catches many applicants out: 50x70mm, taller and larger than the common European 35x45mm. At 300 dpi this works out to roughly 420x590 pixels. Because the format is unusual, a photo prepared for a U.S. or European passport will not fit a Canadian passport application, and Immigration, Refugees and Citizenship Canada (IRCC) requires the exact dimensions with the face correctly proportioned inside them.
The Canadian rule most people miss is the precise face measurement: the distance from the chin to the crown of the head must be between 31mm and 36mm. The background must be plain white or light-coloured, and the image must show a clear, sharp, front-facing view of your full face. You should have a neutral expression with your mouth closed, both eyes open, and no shadows on your face or in the background. Uniquely, Canada also requires that one of the two identical prints be signed on the back and that a guarantor and the photographer's details are recorded, so Canadian photos usually need to be printed as a pair rather than only submitted digitally.
Pixohub sizes your Canadian passport photo to the 50x70mm / 420x590 pixel format directly in your browser, with no upload to any server, giving you strong privacy for your ID photo, and it is completely free. IRCC specifications, including the guarantor and endorsement rules, are updated periodically. Always verify the current requirements on canada.ca before printing so your passport application is not returned for a photo that no longer meets the standard.
