The Two Global Biometric Templates
Standardized geometric dimensions enforced by international ICAO 9303 facial recognition systems
Over 190 countries worldwide standardize on one of two geometric passport picture formats. Getting the exact millimeter, centimeter, and pixel measurement right is mandatory for automated border control and consular e-visa validation.
2 × 2 Inches (51 × 51 mm)
5.1 × 5.1 cmStandard for US Passports, Indian Passports & OCI, US Visas (DS-160), and Central American documents. At 300 DPI, digital upload requires exactly 600 × 600 pixels (Aspect Ratio 1:1).
35 × 45 mm (3.5 × 4.5 cm)
1.38 × 1.77 inStandard for European Schengen Visas, UK Passports & Visas, Australia, Canada, New Zealand, and Singapore. At 300 DPI, digital upload requires 413 × 531 pixels (Aspect Ratio 7:9).
Head Height & Biometric Ratios
Critical RuleOver 40% of photo rejections occur due to incorrect head height percentage. Cropping only the outer border is not enough:
- US & India 2×2 in: Head height must measure 1" to 1 3/8" (50% to 69% of photo height).
- Schengen 35×45 mm: Head height must measure 32 mm to 36 mm (70% to 80% of photo height).
- Eye Line Height: Eyes must sit 28 mm to 33 mm from the bottom edge.
Specialized Photo Formats & Standards
Specific photo sizes required for marriage certificates, official exams, and Asian ID cards
Photo with Name & Date
Many recruitment bodies (SSC, Railway exams, state PSC, and select visa portals) require candidate name and date of photograph imprinted in clear font at the bottom.
Marriage Certificate 2B Size
Marriage registration certificates and joint spouse applications standardly require 2B size photos measuring 2 × 2.5 inches (50.8 × 63.5 mm / 5.1 × 6.3 cm) or 600 × 750 px.
3×4 Blue Background Format
Popular in East Asian countries (Japan, Vietnam, Korea) and institutional ID cards, 3×4 cm (30 × 40 mm) photos often specify a solid light blue background color.
