RRB NTPC upload sizes
Non-Technical Popular Categories, Graduate (CEN 06/2026) and Under-Graduate (CEN 07/2026), conducted by Railway Recruitment Boards. Sizes below are from the CEN 06/2026 and 07/2026.
| Upload | Official size | Pixels used here | File size |
|---|---|---|---|
| Signature | Signature: JPG/JPEG, 30 KB to 49 KB, minimum 140 x 60 pixels (width x height), scanned at minimum 100 DPI, centred in a 35 mm x 20 mm box. (para 14.5.1) | 420 × 180 (our choice) | 30–49 KB |
Rules to follow
Signature
Sign in black ink on white paper.
Cursive signature; not in block or capital letters.
140 x 60 px is a MINIMUM, not a target: a 140 x 60 JPEG cannot reach 30 KB, so the scan must be larger.
Good to know
No photo file is uploaded. The photo is captured live by webcam or the phone's front camera during the application.
Live photo: no cap, mask or glasses/spectacles; non-white (preferably dark) clothing; face centred; you can retake before submitting. Photographing a printed or digital photo leads to rejection.
SC/ST certificate (free travel pass only): PDF under 400 KB.
Read by a sub-agent from the CEN PDF in the browser; the RRB firewall now blocks direct downloads, so it was not re-checked in this pass.
NTPC adds: pure plain white background, head fills at least 50% of the frame, eyes open. If the live photo does not match your ID, upload Annexure VIII signed by a Gazetted Officer (paras 1.7, 14.4).
