Is the CUET UG 2027 notification out?

Not as of 4 November 2026. Registration is expected early in 2027.

What signature size does CUET use?

The 2026 form asked for a JPG signature between 10 and 50 KB.

NTA has not published the CUET UG 2027 bulletin. Registration is expected early in 2027. The 2026 upload rules are a good starting point.

Status checked 4 November 2026: the CUET UG 2027 bulletin has not been released. Sizes are from the 2026 cycle.

Upload	2026 rule	Tool
Photograph	JPG, 10–200 KB, colour, light background	CUET photo
Signature	JPG, 10–50 KB	CUET signature

The CUET signature limit of 50 KB is lower than NEET and JEE Main, so do not re-use a 100 KB signature file from another form.
