Quick conversion table
The physical size does not change when you switch units. The numbers below are different ways to describe the same square.
| Unit | 2x2 photo value | Use it when |
|---|---|---|
| Inches | 2 x 2 in | A printer, form or photo lab specifies physical inches. |
| Centimeters | 5.08 x 5.08 cm | A form uses metric measurements and expects an exact conversion. |
| Millimeters | 50.8 x 50.8 mm | You need the exact metric conversion; some official instructions round this to 51 x 51 mm. |
| Pixels | 600 x 600 px at 300 PPI | You are preparing a digital file for a 2 x 2 inch print at 300 pixels per inch. |
Physical size and pixel size are different
Pixels describe the digital image. Inches, centimeters and millimeters describe the intended physical print. A 600 x 600 file is not automatically two inches wide unless the print workflow preserves the intended size. This site's JPEG export includes 300 PPI metadata to make that relationship explicit for compatible print software.
