Why Passport Photo Aspect Ratios Differ by Country
The United States and a few other nations specify a square 2×2 inch (51×51 mm) format with a strict 1:1 ratio. Most European, Asian, and Commonwealth countries mandate the ICAO biometric standard of 35×45 mm (7:9 ratio). Verifying your target country's specifications prevents rejection by automated consulate scanners.
