RRB (Railway Recruitment Board) Photo & Signature Size
RRB applications capture your photograph live inside the form, by webcam or the phone's front camera, so you never upload a photo file. The signature is the one image you prepare: JPG/JPEG, 30–49 KB, at least 140 × 60 pixels, scanned at 100 DPI or more.

Application-specific notes for RRB
- Follow the capture screen's own instructions for lighting and framing; nothing prepared in advance substitutes for the live photo. RRB asks for a pure plain white background with no scenery or pictures behind you, and dark, non-white clothes that cover your shoulders and chest, so you stand out from the wall.
- Taking the live photo of a printed or digital copy of an old photo is not allowed; RRB summarily rejects such applications.
- The signature's size band is narrow — only 19 KB wide — so compress deliberately rather than aiming for the smallest file you can make.
- Sign in running handwriting (joined letters) with a black ink pen on white paper — not in block, capital or separated letters — and keep the signature centred in a 35 × 20 mm box, then scan just that box.
- RRB lists the signature faults that get an application rejected at any stage: someone else's signature, a non-white background, non-black ink, block or capital letters, a blurred or partly hidden signature, an image that isn't a signature, a blank, or a thumb impression in place of a signature.
- Because the photograph is captured live and only the signature is uploaded, the usual advice to prepare both files in advance does not apply here. Spend the preparation time on the signature — it is the only file you control and the only one that can be rejected for a size fault.
- The signature canvas of 140 x 60 pixels is close to 7:3. Keep the signature centred and use the available width without touching the edges, so the crop does not leave excessive empty margins or clip a stroke.
About this exam
RRB recruits through Centralised Employment Notices (CENs), published on every regional RRB website. These rules are from CEN 06/2026 for the NTPC graduate posts (7 October 2026); CEN 05/2026 for paramedical posts gives the same signature rules.

Frequently asked questions
How do I resize the RRB signature to 140 × 60 pixels?
Sign on plain white paper, take a clear photo or scan, and open it in the resizer on this page. It crops to 140 × 60 pixels and keeps the JPG between 30 and 49 KB, the size RRB's notice sets.
