Passport Photo Size: The Complete 2026 Guide for Every Country

Why passport photo size matters more than you think

Every country runs your photo through automated software before a human ever sees it. The software measures three things in this order: overall dimensions, head height inside the frame, and eye position. A photo that's even 1–2 millimeters off gets rejected automatically — and most applicants never find out which check failed.

The US Department of State, for example, uses an automated validator at travel.state.gov that rejects photos in under a second if the pixel dimensions or biometric framing don't match. Same logic applies to UK gov.uk, Schengen consulates, and Canada's IRCC portal.

So before we get into smiles, glasses, or backgrounds — let's nail the dimensions.

Passport photo size by country (2026 chart)

Here's the official passport photo size for every major issuing country, with head-height requirements and digital pixel specs.

🇺🇸 United States

• Print size: 2 × 2 inches (51 × 51 mm) — square
• Head height: 1 to 1⅜ inches (25–35 mm) from chin to top of head
• Digital size: 600 × 600 to 1200 × 1200 pixels
• File size: 54 KB minimum, 10 MB maximum
• Background: White or off-white
• Format: JPEG, JPG, or HEIC

🇬🇧 United Kingdom

• Print size: 35 × 45 mm (3.5 × 4.5 cm) — portrait rectangle
• Head height: 29–34 mm (chin to crown)
• Digital size: 600 × 750 px minimum for online applications
• Background: Plain light grey or cream (not white — this catches a lot of people)
• Format: JPEG, 50 KB to 10 MB

🇪🇺 Schengen Area (all 29 countries)

• Print size: 35 × 45 mm
• Head height: 32–36 mm (70–80% of frame)
• Background: White or very light grey
• Used by: Germany, France, Italy, Spain, Netherlands, Belgium, Austria, and 22 others

🇨🇦 Canada

• Print size: 50 × 70 mm (5 × 7 cm) — the largest standard format
• Head height: 31–36 mm (chin to crown)
• Unique requirement: Photographer must stamp the back of one photo with their name, address, and date
• Background: Plain white or light coloured

🇮🇳 India

• Print size: 35 × 45 mm (changed from 51 × 51 mm in September 2025 to align with ICAO Doc 9303)
• Head height: 32–36 mm
• Background: Plain white
• Note: Old 2×2 inch photos are no longer accepted for new passport applications

🇨🇳 China

• Print size: 33 × 48 mm
• Background: Plain white
• Note: Slightly narrower than the ICAO standard — booth machines often need manual override

Other countries (quick reference)

• Australia: 35 × 45 mm
• Japan: 35 × 45 mm
• South Korea: 35 × 45 mm
• Brazil: 50 × 70 mm
• Mexico: 35 × 45 mm
• Saudi Arabia: 40 × 60 mm
• UAE: 43 × 55 mm
• Turkey: 50 × 60 mm
• Russia: 35 × 45 mm
• Indonesia: 51 × 51 mm (red background — yes, red)
• Spain: 26 × 32 mm (smaller than EU standard — yes, even though Spain is Schengen)
• Norway: 35 × 40 mm
• Greece: 40 × 60 mm

Quick rule: Always pick the passport photo size for the issuing country, not your nationality. A US citizen applying for a Schengen visa needs 35 × 45 mm, not 2 × 2.

The three passport photo size standards

Despite 195 countries having their own rules, almost every passport photo falls into one of three size families:

1. The 2 × 2 inch square (51 × 51 mm)

Used by the US, India until 2025, Indonesia, and a handful of Latin American countries. The US adopted this format before ICAO existed and never switched. If you've grown up in the US, this is what feels "normal" — but globally, it's the minority format.

2. The 35 × 45 mm rectangle (the ICAO standard)

This is the international biometric standard set by ICAO Doc 9303 — the same document that defines machine-readable passports. Used by the UK, all 29 Schengen countries, India (since September 2025), Australia, Japan, South Korea, and most of Asia and the Pacific. If you're outside North America, this is probably your size.

3. The 50 × 70 mm portrait (Canada's format)

Canada is the only major country still using this larger format. The extra space accommodates the photographer's stamp on the back — a unique requirement.

Converting passport photo size: mm, inches, pixels

You need pixel dimensions for digital uploads and millimeters for print. Here's the math.

At 300 DPI (the universal print standard):

• 2 × 2 inches = 600 × 600 pixels = 51 × 51 mm
• 35 × 45 mm = 413 × 531 pixels = 1.38 × 1.77 inches
• 50 × 70 mm = 591 × 827 pixels = 1.97 × 2.76 inches
• 33 × 48 mm = 390 × 567 pixels = 1.30 × 1.89 inches

Conversion shortcuts:

• mm to pixels at 300 DPI: multiply by 11.81
• inches to mm: multiply by 25.4
• pixels to mm at 300 DPI: divide by 11.81

One warning: don't upscale a small image to hit pixel targets. Going from 200 × 200 to 600 × 600 doesn't add detail — it invents pixels, and consular AI flags this immediately. Start with a high-resolution photo and crop down.

Head size requirements (the rule everyone misses)

Getting the overall dimensions right is easy. Getting the head height inside the frame right is where most photos fail. Here's what each country requires:

• US: Head must be 25–35 mm tall (1 to 1⅜ inches), measured from the bottom of the chin to the top of the head — including hair
• UK: 29–34 mm chin to crown
• Schengen: 32–36 mm (70–80% of frame height)
• Canada: 31–36 mm
• India: 32–36 mm

If your head fills less than the minimum, the photo looks "too zoomed out" and gets rejected for biometric mismatch. If it fills more than the maximum, it gets cropped wrong by automated systems and fails too.

This is why studios charge $15–20 for a passport photo: they're not paying for the print — they're paying for someone trained to frame the head correctly. Our free passport photo tool applies the correct head-height crop automatically based on your selected country.

Digital passport photo size: pixel and file rules

Online applications add another layer of requirements on top of physical dimensions. The big ones for 2026:

US Department of State (online passport renewal)

• Dimensions: 600 × 600 to 1200 × 1200 pixels (square)
• File size: 54 KB to 10 MB
• Format: JPEG, JPG, or HEIC (HEIC accepted since 2024)
• Color only — no black and white

US DS-160 visa application

• Dimensions: 600 × 600 to 1200 × 1200 pixels
• File size: under 240 KB (much smaller than passport renewal)
• Format: JPEG only

UK online passport application

• Dimensions: 600 × 750 px minimum
• File size: 50 KB to 10 MB
• Format: JPEG

Schengen ETIAS

• Dimensions: 413 × 531 pixels minimum (35 × 45 mm at 300 DPI)
• File size: typically under 5 MB
• Format: JPEG

New for 2026: AI-edited photos are rejected

This is the rule change catching most applicants off guard. As of 2026, both the US State Department and USCIS reject photos that show signs of AI editing — including beauty filters, portrait mode smoothing, color correction, red-eye removal, and skin retouching.

Per official State Department guidance, photos must be unaltered representations. "Natural appearance" means the photo software in your phone — which auto-applies smoothing — can actually cause rejection.

How to avoid this:

• Turn off beauty mode, portrait mode, and any "smart" filters before shooting
• Don't use Instagram, Snapchat, or filter apps to "improve" the photo
• Don't whiten teeth, smooth skin, or adjust eye color in editing
• Background replacement is allowed (it's not a face edit) — but make it look natural

The 5 most common rejection reasons (and how to avoid them)

1. Wrong dimensions — Submitting a 2×2 inch photo for a Canadian application, or 35×45 mm for a US one. Fix: Always check the issuing country's exact spec.
2. Head too small or too large — The most-missed rule. Fix: Use a tool with country-specific head-height guides.
3. Background not compliant — UK requires light grey, not white. Indonesia requires red. Fix: Replace background to match official requirement.
4. AI editing artifacts — Phone "beauty modes" trigger automated rejection. Fix: Disable filters before shooting.
5. Glasses, smile, or accessories — Most countries (US since 2016) ban glasses entirely. Neutral expression required. Fix: Remove glasses and don't smile.

Frequently asked questions about passport photo size

What is the standard US passport photo size?

2 × 2 inches (51 × 51 mm), with head height between 1 and 1⅜ inches (25–35 mm). This applies to both passport books and passport cards, and to most US visa applications submitted via DS-160.

Is the UK passport photo size the same as Schengen?

Yes — both use 35 × 45 mm. But there's one critical difference: the UK requires a light grey or cream background, while Schengen accepts white. A pure-white UK photo can be rejected.

Can I use the same passport photo for multiple countries?

Only if they share the exact same dimensions and background rules. The UK, Schengen, India, Australia, and Japan all use 35 × 45 mm, so one well-shot photo (on a neutral background) can work for several. The US (2×2) and Canada (50×70) require separate photos.

What pixel size do I need for a passport photo?

At 300 DPI: 2×2 inch needs 600 × 600 pixels, 35×45 mm needs 413 × 531 pixels, 50×70 mm needs 591 × 827 pixels. For US online applications, the State Department accepts up to 1200 × 1200 pixels.

How big should my head be in a passport photo?

It depends on the country. US: 25–35 mm tall. UK: 29–34 mm. Schengen: 32–36 mm. The head must fill roughly 50–80% of the frame height depending on the standard — but you'll want a tool that frames this automatically rather than guessing.

Why are passport photo sizes different by country?

Most countries follow ICAO Doc 9303 (35 × 45 mm), but the US adopted 2 × 2 inches before ICAO existed and kept it for continuity. Canada uses a larger format (50 × 70 mm) to fit the photographer's stamp on the back. There's no "right" size — only the right size for your application.

Can I print my own passport photo at home?

Yes. Use photo paper (matte or glossy both work), a color printer, and 300 DPI resolution. The hard part isn't printing — it's getting the head positioned correctly within the frame. A free tool with country presets handles that for you.

Did India really change its passport photo size?

Yes. In September 2025, India switched from 51 × 51 mm (square, matching the US) to 35 × 45 mm (matching ICAO and the UK). Old 2×2 inch photos are no longer accepted for new applications.
