There is no single international passport photo size that works for every country.
What is broadly standardized is biometric quality: front-facing pose, neutral expression, visible eyes, even lighting, and a plain background. But print size, pixel dimensions, background color, and file-size limits still vary by country and portal.
This 2026 guide compares common country requirements and highlights the mistakes that most often cause rejections.
Quick Comparison
| Country / Region | Common Print Size | Typical Note |
|---|---|---|
| United States | 2 × 2 in / 51 × 51 mm | White/off-white background, head 25-35 mm |
| United Kingdom | 35 × 45 mm | Printed photo 45 × 35 mm |
| Canada | 50 × 70 mm | Rules vary by route |
| France | 35 × 45 mm | White background is not accepted |
| Spain | 32 × 26 mm | Smaller than many EU formats |
| China (visa) | 33 × 48 mm | White background, head-size constraints |
| India (common Passport Seva route) | ICAO style, often 630 × 810 px | Face 80-85% |
Always verify the latest official portal before submission.
