CTET photograph: what is specific to this exam

These CTET 2026 rules come from the CBSE notice “CTET September 2026 Information Bulletin”, page 3, last checked on 22 Oct 2026. The CTET form usually opens around May, June, November or December.

From our CTET notes

• CTET is one of the few exams that gives both a physical size and a KB range for each file. The photo is 3.5 cm wide by 4.5 cm high at 10–100 KB, and the signature is 3.5 cm long by 1.5 cm high at 3–30 KB. Both must be JPG/JPEG, and both uploads are mandatory.
• Photo. A recent colour photo against a light wall. Crop from the top of the head to just below the shoulders; the crop box is locked to the 3.5×4.5 shape.
• CTET's signature range starts at 3 KB, far lower than most exams. You will rarely hit the minimum; the bigger risk is a signature photo taken at full phone resolution, which can be several megabytes. Auto-fit takes it down to the 3–30 KB range.
• State TETs often use different limits. HTET wants the photo at 20–50 KB and REET at 20–50 KB, so a CTET photo near 100 KB will fail there. Fit it again for each exam.
• If the error mentions the image dimension, the photo was probably cropped to a different shape; redo the crop with the CTET preset. If it mentions size, check the KB on the Pass check card.

Upload errors and how to fix them

These are the messages the CTET portal shows. Each one has a fix.

Error: Invalid file size

Fix: CTET checks the KB range strictly: photo 10–100 KB, signature 3–30 KB. Auto-fit lands inside both.

Error: Invalid file type

Fix: Only JPG/JPEG is accepted for photo and signature. SahiSize converts HEIC, PNG and WebP to a real JPG.

Error: Photo and signature are not clear

Fix: Retake in daylight against a plain wall; for the signature use a dark pen on white paper and keep Clean signature on.

Error: Image dimension should be 3.5 cm x 4.5 cm

Fix: The CTET portal expects the photo in 3.5×4.5 cm proportions. SahiSize locks the crop to that shape and writes 200 DPI so it measures 3.5×4.5 cm.
