Check your photo dimensions (width × height) in pixels, inches, or millimeters.
Divide width by height. For example: 600px ÷ 600px = 1.0 (1:1 ratio)
Compare your ratio against the required ratio for your target country.
Use our tool to automatically crop and adjust to the correct aspect ratio.
Upload your photo and we'll automatically check the aspect ratio and crop it to meet passport requirements for your target country. Get the perfect proportions every time.

The passport photo ratio (aspect ratio) is the proportional relationship between width and height. The most common ratios are 1:1 (square) for US passports and 7:9 for European passports. This determines the photo's shape and proportions.
US passport photos use a 1:1 aspect ratio (square format). The standard size is 2×2 inches, which maintains a perfect square shape with equal width and height dimensions.
European passport photos use a 7:9 aspect ratio. The standard size is 35×45 mm, making the photo slightly taller than it is wide. This is the required format for EU countries and Schengen visas.
No, European passports require a 7:9 aspect ratio (35×45 mm), not square. Using a 1:1 square photo will not meet EU passport requirements and may cause your application to be rejected.
Divide the width by the height. For example: 35mm ÷ 45mm = 0.78 (7:9 ratio). Our online tool automatically calculates and adjusts the correct aspect ratio for any country's requirements.
Different countries have established their own standards over time. The US prefers square photos for consistency, while Europe uses 7:9 for better facial detail in a portrait orientation. Each format optimizes for their specific document layouts and printing systems.
