Passport Photo Size Requirements by Country — Complete 2026 Guide

Every country has different passport photo requirements — and submitting the wrong size can lead to your application being rejected, causing costly delays. This guide covers the exact dimensions for the most common countries in 2026, and shows you how to resize and compress any photo to meet them instantly and for free.

Why Passport Photo Size Matters

Passport and visa applications are processed by government systems that scan photos digitally. If your photo does not match the required dimensions, aspect ratio, file size or DPI, the system flags it for rejection. Even a photo that looks correct to the human eye can fail automated checks if the pixel dimensions are slightly off.

Why Countries Use Different Sizes

The variation in passport photo sizes across countries exists for a mix of historical and practical reasons. Many countries adopted their current standard before international biometric passport standards were widely formalised, and changing an established standard requires updating all the systems — cameras, printing equipment, processing software — that use it, which creates inertia. The ICAO (International Civil Aviation Organization) has pushed for standardisation around the 35×45mm format for biometric passports, which is why many countries have converged on this size, but exceptions remain — most notably the US, which has long used the square 2×2 inch format and hasn't moved away from it despite the international standard. Understanding which category your target country falls into (ICAO-standard or a national variant) helps narrow down the requirements before looking up the specific dimensions.

Standard Passport Photo Sizes by Country

• USA Passport: 2 × 2 inches (51 × 51mm) — square format, white background, face centred
• UK Passport: 35 × 45mm — standard ICAO format, light grey or cream background
• UAE / Saudi Arabia: 40 × 60mm — white background, recent photo
• Pakistan (NADRA): 40 × 50mm — white background, frontal view
• India Passport: 35 × 45mm — white background, face covering 70-80% of frame
• EU Standard (Germany, France etc.): 35 × 45mm — ICAO biometric standard
• China: 33 × 48mm — white background, required colour
• Philippines: 35 × 45mm — white background

Pixel Equivalents at 300 DPI (Print Standard)

When preparing a digital passport photo, the dimensions must be converted to pixels at 300 DPI (dots per inch), which is the standard print resolution for official documents.

• 35mm = 413px at 300 DPI
• 40mm = 472px at 300 DPI
• 45mm = 531px at 300 DPI
• 50mm = 591px at 300 DPI
• 51mm (2 inch) = 600px at 300 DPI

What Are the File Size Requirements?

Many online visa and passport portals have strict file size limits — commonly between 10KB and 2MB. A high-resolution portrait photo can easily be 4–8MB straight from a smartphone camera. Our tool lets you compress any photo to an exact target file size in KB, so you can meet portal requirements precisely.

Why Digital Submissions Often Have Both Dimension AND File Size Requirements

It can seem redundant to specify both pixel dimensions and a maximum file size for a digital photo submission — if the dimensions are set correctly, why does the file size also matter? The answer is that two photos with identical pixel dimensions can have very different file sizes depending on how they're compressed. A JPG saved at 95% quality will be much larger than the same image saved at 70% quality, even at identical dimensions. Portals specify a file size cap partly for practical reasons (storing many large files has a cost) and partly because some automated processing systems have difficulty with unusually large files even if the dimensions are correct. The target is to be within the specified dimension range while also staying under the file size cap, which typically means saving as JPG at moderate-to-high quality and checking the output file size before submitting.

Tips for a Compliant Passport Photo

• Use a plain white or light grey background — avoid patterns or colours
• Ensure your face takes up 70–80% of the frame
• Look directly at the camera with a neutral expression
• No glasses (most countries now require this)
• Good even lighting — avoid harsh shadows on face or background
• No hats or head coverings unless for religious reasons
• Photo must be taken within the last 6 months
