2x2 photo size: pixels, inches, centimeters and crop rules
A 2x2 photo is a square image measuring 2 inches by 2 inches, or 51 × 51 mm. The canvas is only one part of compliance: the face, eye line, background and file contract still depend on the document.
Quick answer
2x2 inches equals 51 × 51 mm and a 1:1 ratio
For a normal 300 DPI print, prepare about 600 × 600 pixels. For an online upload, use the exact pixel range published by the application portal instead of relying on DPI alone.
Reference table
| Requirement | Typical value | Why it matters |
|---|---|---|
| Physical size | 2 × 2 in / 51 × 51 mm | Finished print canvas |
| Aspect ratio | 1:1 square | Prevents stretched or letterboxed faces |
| 300 DPI equivalent | 600 × 600 px | Useful print starting point |
| Background | White or off-white where specified | Must be even and shadow-free |
| Face framing | Document-specific | Head band and eye line are separate checks |
2x2 pixels at common resolutions
At 300 DPI, 2 inches produces 600 pixels in each direction. At 600 DPI, it produces 1,200 × 1,200 pixels. A portal may publish a different range, and that digital contract takes precedence over a print conversion.
Do not confuse a square canvas with a square crop of the face
The canvas is square, but the person remains a normal head-and-shoulders portrait inside it. Keep the full hair, chin and required shoulder area visible instead of zooming tightly into the face.
Where 2x2 is used
The format is strongly associated with US passport, visa and immigration applications, but not every US route uses identical file limits.
Frequently asked questions
01What is 2x2 photo size in cm?
It is 5.08 × 5.08 cm, normally rounded and printed as 51 × 51 mm.
02How many pixels is a 2x2 photo?
At 300 DPI it is 600 × 600 pixels; at 600 DPI it is 1,200 × 1,200 pixels. Use the portal range when one is published.
03Is 2x2 the same as passport size?
Not universally. It is the standard US passport shape, while many countries use a portrait format such as 35 × 45 mm.
04Can I crop any photo to 2x2?
Only when the source leaves enough space around the hair, chin and shoulders. A tight selfie cannot be repaired by cropping.
