3x4cm ID Photo Size Guide
Background color, file size limits, and composition rules may differ by application site. Use these as common reference points and always double-check the official submission guide.
| A common ID photo size is 3x4cm. |
| At 300dpi, that equals 354x472px. |
| Accepted formats may differ by site, typically JPG, JPEG, or PNG. |
| Center the face before saving the final file. |
| Check that headroom and chin spacing are not too tight or too wide. |
| Review background color, file size limits, and recency rules on the submission site. |
| Photos that include the upper body and shoulders are easier to crop than close selfies. |
| If the original ratio is different, check the eye and nose position before finalizing. |
| Open the saved file in the real upload screen once to confirm nothing looks cropped awkwardly. |
Frequently Asked Questions
How many pixels is a 3x4cm ID photo?
A 3x4cm ID photo is typically 354x472px at 300dpi. Exact file rules can still vary by application site, so it is best to confirm the official requirements before submission.
Should I save an ID photo as JPG or PNG?
Most submission portals commonly accept JPG or JPEG. Some also support PNG, but if the site does not specify otherwise, JPG is usually the safest choice.
Can I use a phone photo for an ID photo?
Yes. Photos that include the upper body and shoulders are usually easier to crop than very close selfies. After saving, it is still a good idea to preview the file in the real upload form.
How precise do background and margins need to be?
Matching the overall size helps, but many institutions also check background color, headroom, face ratio, and recency. After resizing, review the official submission rules once more.
