How to Get a Passport Photo to the Right Size at Home
July 12, 2026
You can set the pixel size of a passport photo at home in under a minute. What you cannot do with a resizer alone is guarantee the photo passes, because passport photos have strict rules beyond size. Here is the honest version of both.
The pixel sizes
Passport photos are printed at fixed dimensions, and at the standard 300 dpi print resolution those work out to exact pixel sizes:
| Standard | Print size | Pixels at 300 dpi |
|---|---|---|
| US | 2 x 2 inches | 600 x 600 |
| UK and EU | 35 x 45 mm | 413 x 531 |
The passport photo maker has both as one-click presets. Drop your photo in, pick your standard, and choose cover so the photo fills the frame and the overflow is cropped, or fit to keep the whole photo with padding. Save as JPG, which is what most photo printers and online applications expect.
35 x 45 mm in pixels and inches
The 35 by 45 mm size trips people up because it gets asked for in three different units. Here is the same photo in all of them:
| Unit | 35 x 45 mm equals |
|---|---|
| Millimeters | 35 x 45 mm |
| Inches | 1.38 x 1.77 in |
| Pixels at 300 dpi | 413 x 531 |
| Pixels at 600 dpi | 827 x 1063 |
Use 300 dpi for a standard print or online upload. Step up to 600 dpi only if the authority asks for it, since it makes a larger file for the same physical size. The US 2 by 2 inch size works out to 51 by 51 mm, which is 600 by 600 pixels at 300 dpi.
Common passport sizes by country
Most countries use one of two sizes, but a few have their own. Check yours before you print.
| Country or region | Print size | Pixels at 300 dpi |
|---|---|---|
| US, India | 2 x 2 in (51 x 51 mm) | 600 x 600 |
| UK, EU, Schengen, Australia, New Zealand | 35 x 45 mm | 413 x 531 |
| Canada | 50 x 70 mm | 591 x 827 |
| China | 33 x 48 mm | 390 x 567 |
The passport preset covers the two common sizes directly. For any other size, type the exact pixel figure from the table into the image resizer and it will hit it exactly.
What the size does not cover
This is the part people miss. Getting the pixels right is necessary but not sufficient. Official passport photos also require:
- A specific head size and position within the frame.
- A plain, light, evenly lit background.
- A neutral expression with both eyes open and the face clearly visible.
- No shadows, glare, or heavy filters.
A resizer sets the dimensions. It does not check any of the rules above. So confirm the exact requirements with the issuing authority, frame and light your shot to meet them, and then use the preset to lock in the correct pixel size.
A practical order
- Take the photo against a plain, well-lit wall with the head centered.
- Crop it to a square (for US) or the right ratio so the head sits where the rules want it.
- Apply the passport preset to set the final pixel size.
- Print at 300 dpi or upload as directed.
Everything happens in your browser, so your photo is never uploaded and there is no watermark on the result.
Common questions
What is 35 x 45 mm in pixels? 413 by 531 pixels at 300 dpi, or 827 by 1063 at 600 dpi. Use 300 dpi unless your passport authority asks for higher.
What is 45 mm x 35 mm in inches? About 1.77 by 1.38 inches. The 35 by 45 mm passport frame is 1.38 inches wide and 1.77 inches tall.
What size is a US passport photo in pixels? 600 by 600 pixels at 300 dpi, which is the 2 by 2 inch (51 by 51 mm) square the US requires.
How do I set the exact pixel size? Type the pixel figures from the tables above into the image resizer, or pick the one-click passport preset for the US or 35 x 45 mm size.
Does the right pixel size mean my photo will pass? No. Size is only one rule. Head position, background, lighting, and expression all have to meet the issuing authority's requirements too. The resizer handles the dimensions, not the rest.
