2×2 Inch Photo in Pixels: Exact Dimensions for Every DPI
Reviewed: 2026-05-01
The pixel dimensions of a 2×2 inch photo depend on the DPI (dots per inch) resolution. Here's the exact conversion:
2×2 Inch Photo Pixel Dimensions
| DPI | Pixels | Common use |
|---|---|---|
| 72 | 144×144 | Screen/web only (too low for print) |
| 96 | 192×192 | Screen display |
| 150 | 300×300 | Low-quality print |
| 200 | 400×400 | Acceptable print |
| 300 | 600×600 | Standard print quality (most common) |
| 600 | 1200×1200 | High-quality print |
Which documents use 2×2 inch photos?
The 2×2 inch (51×51mm) format is primarily used by the United States:
US Passport — 600×600 to 1200×1200 pixels
US Visa (all types) — 600×600 pixels
DV Lottery — exactly 600×600 pixels, max 240 KB
US Green Card — 600×600 pixels
India OCI Card — 51×51mm (same size, 200-1500px)
Most other countries use the ICAO 35×45mm format instead.
The formula
Pixels = inches × DPI
So for 2×2 inches at 300 DPI: 2 × 300 = 600 pixels per side.
Important: DPI matters for print, not for digital
When submitting digitally (uploading to a website), only the pixel dimensions matter. DPI is only relevant when printing. A 600×600 pixel image printed at 2×2 inches is inherently 300 DPI — you don't need to set DPI metadata separately.
