CTET Photo & Signature Requirements (2026)
CBSE's exact photo and signature specs for CTET, and the errors that cause auto-rejection.
CBSE states CTET image requirements in centimetres rather than pixels, which is where most candidates go wrong — a 3.5×4.5 cm photo means roughly 350×450 pixels. The portal checks dimensions and file size independently, so a photo that looks right can still fail. This guide converts the specification into the numbers you actually need.

|---|---|---|---|
| Photograph | 350×450 px | 10–100 KB | JPG |

Why applications get rejected
- Photo outside the 10–100 KB range or the wrong dimensions
- Signature outside the tight 3–30 KB range
- PNG or a renamed HEIC file — CBSE checks the real format
- A signature scanned vertically or with the ends cropped off
