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.
