About RRB Group D Recruitment
RRB Group D is conducted by the Railway Recruitment Boards to fill posts such as Track Maintainer, various Helper/Assistant roles across technical departments, and Pointsman, spread across Indian Railways zones. It is historically one of the largest recruitment drives in the country by applicant volume, with crores of candidates applying in a single cycle.
Because so many candidates apply at once, the application portal enforces photo and signature specifications strictly and automatically. A mismatched file can block your submission at the very last step, so it's worth getting the specification right before you start filling the form.

- Ensure your full face is clearly visible, including both ears
- Wear formal or semi-formal clothing — no sleeveless tops
- Ensure adequate, even lighting — no harsh shadows on your face
- Keep a neutral, natural expression with mouth closed
- Ensure the photo is in focus and not blurry
Don'ts
- Do not wear sunglasses or tinted glasses

Many candidates assume RRB Group D uses the same strict 50KB photo limit as RRB NTPC, and end up over-compressing their photo far more than necessary. RRB Group D actually allows up to 100KB — so there is no need to squeeze your photo down to NTPC-level compression. Always check the exact KB ceiling for the specific RRB exam you're applying to.

What Pixel Dimensions Should RRB Group D Photo Be?
The RRB notification specifies the dimensions in millimetres (35mm × 45mm), but photo portals work in pixels. The equivalent pixel dimensions depend on the resolution (DPI) used:
| Resolution | Pixel Width | Pixel Height |
|---|---|---|
| 96 DPI (standard screen) | 132 px | 170 px |
| 150 DPI (medium print) | 207 px | 266 px |
| 300 DPI (high quality print) | 413 px | 531 px |
Our tool uses 96 DPI by default, which is standard for web uploads. SarkariKagaz.pro automatically outputs the correct pixel dimensions for the RRB Group D preset, so you never need to calculate this yourself.
RRB Group D 2026 — Other Important Notes
- The same photo must be used throughout the entire examination process — do not change your photo between CBT stages, PET, and document verification
- Bring printed copies of this same photo to the examination centre
- The RRB portal may validate your photo automatically — if it fails, the error will appear immediately after upload
- Always download and save your resized photo in a clearly named folder before going to fill the form
