35x45 Photo Size Guide for Passports and Visas

35x45mm Is the Most Common Biometric Photo Size Worldwide

The 35x45mm format is widely used for European passports, Schengen visas, UK-style documents, and many other ICAO-aligned applications. That makes it common, but not identical across every country.

• Common for Schengen visa applications.
• Used for many European and ICAO-style passport flows.
• Usually paired with strict biometric head-height rules.

Why Two 35x45 Photos Can Still Have Different Rules

The dimensions may match, but countries can still differ in background preference, head measurement range, file format, and recency requirements.

• UK passport photos may prefer cream or light grey backgrounds.
• Schengen consulates may accept light grey or white depending on the country.
• Some authorities care more about print output, while others focus on digital upload readiness.

When to Use a 35x45 Checker

If your document uses 35x45mm or something close to that biometric format, start with a dedicated 35x45 checker and then confirm any country-specific differences.
