GAT-B / BET Photo & Signature Size 2026
GAT-B / BET stands for Graduate Aptitude Test – Biotechnology / Biotechnology Eligibility Test.
Photo requirements
GAT-B / BET takes your photograph through your camera during the application itself. You cannot upload a saved photo, so there is no pixel size or file size to match. Get the capture right instead.
How to get the capture right
- •Capture a live photograph using the device camera during the online application process
- •Upload a recent passport-size colour photograph with at least 80% of the face (including both ears) clearly visible
- •Use a plain white or light-coloured background with adequate lighting
- •Ensure both the live photograph and uploaded photograph are clear, recent and belong to the candidate only
