RRB NTPC, Group D, ALP, and other Railway recruitment exams require a photo of 413×531 pixels (3.5×4.5 cm at 300 DPI) in JPEG format, between 15 KB and 100 KB. The Railway portal is relatively lenient on file size compared to SSC and IBPS — but pixel dimensions must still be exact.
The Railway Recruitment Board portal validates these specifications automatically on upload:
| Requirement | Specification | Notes |
|---|---|---|
| Pixel dimensions | 413×531 px | 3.5×4.5 cm at 300 DPI |
| File size | 15 KB – 100 KB | Portal accepts within this range |
| Format | JPG | JPEG compression |
| Resolution | 300 DPI | Print quality standard |
| Background | Plain white | No shadows, no patterns |
| Face coverage | 70–80% | Face centred, looking directly at camera |
| Glasses | Not allowed | Remove before taking photo |
| Expression | Neutral | Mouth closed, eyes open |
⚠ Note: Relatively lenient on file size range
