Stamp Size Photo vs Passport Size Photo: Sizes and When to Use Each
People often ask for a “stamp size photo” when they need a small photo for a form. It is not the same as a passport size photo. A stamp size photo is usually about 20 x 25 mm, while a passport size photo is 35 x 45 mm.
Size comparison
| Photo | mm | cm | Pixels at 300 DPI |
|---|---|---|---|
| Stamp size (usual) | 20 x 25 | 2 x 2.5 | 236 x 295 |
| PAN card | 25 x 35 | 2.5 x 3.5 | 295 x 413 |
| Passport size (India) | 35 x 45 | 3.5 x 4.5 | 413 x 531 |
| Square 2 x 2 inch (US, OCI) | 51 x 51 | 5.1 x 5.1 | 600 x 600 |
“Stamp size” is a common name, not an official standard, so exact sizes vary a little between forms. Always check the size written on your form.
Where each size is used
- Stamp size: small spaces on application forms, ID cards and some exam or admission forms.
- Passport size: passports, many visas, driving licence and general ID applications.
- Square 2 x 2 inch: US visas and passports, and the OCI card.
Can I use a passport photo instead of a stamp size photo?
Only if the form allows it. A larger photo may not fit the space and some offices will not accept it. If you are unsure, ask the office or check the form instructions.
