Passport photo size guides — 35×45 mm and 2×2 inch
Millimetre and inch requirements are the top reason photos get rejected. These guides explain exact dimensions, pixel counts at 300 DPI, and which countries use each format.
Two sizes dominate global passport photos
35×45 mm and 2×2 inches
Most countries outside the Americas use 35×45 mm. The United States standardised on 2×2 inch squares. Pick the guide that matches your client's application form. Passprint automates the entire workflow from upload to print-ready sheet in just a few clicks.
35×45 mm — international standard
Used by India, the UK, Schengen states, and dozens of Asian and Middle Eastern countries.
2×2 in — US square format
51×51 mm with strict head-height percentage for US passports and visas.
Pixel-accurate export
Passprint converts millimetres to pixels at 300 DPI so prints do not drift when trimmed.
Which passport photo size do I need?
Is 35×45 mm the same as 3.5×4.5 cm?
Yes. 35×45 millimetres equals 3.5×4.5 centimetres. At 300 DPI that is approximately 413×531 pixels.
When do I need 2×2 inches instead?
US passport and visa applications require 2×2 inch (51×51 mm) square photos. See the 2×2 inch size guide for pixel dimensions and head-size rules.
