What is the most common passport photo size?
35×45 mm is the most common international size (UK, much of the EU/Schengen, many visas). The United States uses 2×2 inches (51×51 mm). Canada uses 50×70 mm.
Passport Photo Size & ID Photo Dimensions by Country
Passport photo size is not one global standard. Use this chart for common millimetre, inch, and 300 DPI pixel sizes — then confirm the official rule for your application before you print or upload.
What “passport photo size” usually means
Most authorities specify a printed width × height (mm or inches) and a head-height range inside that frame. Digital portals may also ask for pixels or a maximum file size.
300 DPI is a common print standard. Pixel figures below are the print size converted at 300 DPI (rounded). Your portal may ask for a different pixel count — always follow the form you are filling in.

Educational summary of widely published sizes. Head-to-photo ratios and background colours still differ by country — see the requirements guide.

| Canada (passport) | 50 × 70 | 1.97 × 2.76 | 591 × 827 |
| Schengen / EU (common) | 35 × 45 | 1.38 × 1.77 | 413 × 531 |
| India (passport) | 51 × 51 | 2 × 2 | 600 × 600 |
| Philippines (DFA passport) | 35 × 45 | 1.38 × 1.77 | 413 × 531 |
| China (common passport/visa) | 33 × 48 | 1.30 × 1.89 | 390 × 567 |
| Hong Kong / many visas | 40 × 50 | 1.57 × 1.97 | 472 × 591 |
| 4R print sheet (paper, not a photo spec) | 102 × 152 | 4 × 6 | 1200 × 1800 |
- UK photos are 45 mm high × 35 mm wide (portrait). Some shops still say “35×45.”
- Philippines DFA passport photos are commonly 4.5 × 3.5 cm (45 × 35 mm). Many other PH IDs use 2×2 inches instead.
- China and Hong Kong sizes vary by document type (passport, visa, permit). Confirm the form you are using.
- 4R is the paper you print on, not the official portrait size.
ID photo size by country is not always the passport size
Work badges, driving licences, and national IDs often use a different crop from the passport. India and the US reuse 2×2 inches for many visas; the Philippines uses 2×2 inches for NBI, PRC, and postal IDs while the passport is 35×45 mm.
If an employer only says “ID photo,” ask whether they want 35×45 mm, 2×2 inches, or a digital pixel size. You can prepare more than one crop from the same portrait.
How to use these numbers in AI Images Studio
- Pick the preset that matches your document (35×45 mm, US 2×2, custom mm, and others)
- Check that the face is centred and that there is space above the hair
- For printing several copies, download a 4R (4×6 in) sheet — the portraits on the sheet are still your chosen mm or inch size
- For digital upload, follow the portal’s pixel and file-size limits; you may need to resize after download
Confirm the official specification
Governments change photo rules. This table is a starting point, not a substitute for the embassy, passport office, or visa centre instructions you will submit to.
Passport photo size — FAQ
How many pixels is a passport photo at 300 DPI?
A 2×2 inch US photo is 600×600 pixels at 300 DPI. A 35×45 mm photo is about 413×531 pixels. Some websites ask for larger pixel files even when the printed size is the same.
Is 4R a passport photo size?
No. 4R is 4×6 inches — the paper. You print several smaller passport or ID photos on one 4R sheet and cut them out.
Can I use the same photo size for a visa and a passport?
Only if both applications list the same dimensions and rules. Many visas follow the destination country’s passport size; others use 2×2 inches. Check each form.
