How to Convert mm to Pixels
Converting millimetres to pixels requires knowing the DPI (dots per inch) of the output device. The formula is:
Pixels = (mm ÷ 25.4) × DPI
For 50×70 mm at 300 DPI: (50 ÷ 25.4) × 300 = 590.55 ≈ 591 px wide, and (70 ÷ 25.4) × 300 = 826.77 ≈ 827 px tall. This gives us the standard 591×827 pixel target used for Canada passport photo digital exports.
The 25.4 in the formula converts millimetres to inches (since DPI means dots per inch). This same formula works for any mm-to-pixel conversion — just change the mm and DPI values.
Why Does Canada Use 50×70 mm?
Canada is one of the few countries that uses a larger-than-standard passport photo size. While most countries follow the ICAO recommendation of 35×45 mm, Canada adopted the 50×70 mm format to provide more facial detail for identification purposes. This larger format gives immigration officers a clearer view of facial features, especially for biometric matching.

Frequently Asked Questions
Can I use a 35×45 mm photo for a Canada passport?
No. Canada requires 50×70 mm, which is significantly larger than the standard 35×45 mm. Using a 35×45 mm photo will result in rejection because the face will appear too small relative to the expected frame size.
Is 591×827 the exact pixel size, or is it rounded?
It is rounded. The exact calculation gives 590.55 × 826.77 pixels. Since pixels must be whole numbers, we round up to 591×827 to ensure the printed output is at least 50×70 mm at 300 DPI. This slight rounding has no visible impact.
What DPI should I use for a Canada passport photo?
300 DPI is the standard for print-quality photos. This gives you 591×827 pixels for a 50×70 mm photo. Lower DPI values (like 96 or 150) produce images that are too small for printing at the required size.
