15 KB Photo & Signature Size Width and Height in Pixels
A 15 KB image size is the sweet-spot requirement for official document portals across India, including SSC CGL, CHSL, MTS, GD Constable, IBPS PO/Clerk, SBI, RRB NTPC, and UPSC. When portals ask for files in the 10 KB to 20 KB bracket, outputting exactly 15 KB ensures your upload will never trigger file-size-too-large or too-small errors.
To satisfy portal image validation, you must match both file size (KB) and pixel dimensions (Width × Height). Below is the official specifications matrix:
| Exam / Portal Requirement | Allowed File Size | Dimensions in cm / px | Format |
|---|---|---|---|
| SSC CGL / CHSL / MTS Signature | 10 KB to 20 KB (Ideal: 15 KB) | 4.0 cm × 2.0 cm (140 × 60 px) | JPG / JPEG |
| IBPS PO / Clerk / SBI Signature | 10 KB to 20 KB (Ideal: 15 KB) | 140 × 60 px (Aspect 7:3) | JPG |
| Left Thumb Impression (IBPS/SBI) | 10 KB to 20 KB (or 20–50 KB) | 3.0 cm × 3.0 cm (240 × 240 px) | JPG |
| Passport Photograph (SSC/Banking) | 20 KB to 50 KB | 3.5 cm × 4.5 cm (200 × 230 px) | JPG |
