JAM 2027 photo and signature requirements
Choose the correct image type. Published ranges appear below alongside the tool defaults; a preset is not the only allowed image size.
| Item | Requirement / setting | Source or limitation |
|---|---|---|
| Signature | JPG/JPEG · 50–150 KB | Black or dark-blue ink; white paper; no all-capital signatures or initials. |
| Signature size | Width × height: 280 × 80 to 560 × 160 px | Sign inside a 7 × 2 cm box. The source lists signature dimensions height first; we show width first. |
| Photograph | JPG/JPEG · 50–200 KB | Recent colour photo; white or very light background; face occupies at least 50%. |
| Photo size | 240 × 320 to 480 × 640 px; 3.5 × 4.5 cm | The source lists both. Their proportions differ; do not treat the pixel-bound pairs as exact cm equivalents. |
| Tool defaults | Signature 560 × 160 px · photo 420 × 540 px | Signature uses the upper bound. Photo follows the physical-photo proportions within the pixel bounds. Neither is the only permitted pixel size. |
Before uploading: Use the JAM 2027 requirements for this cycle. Pixel ranges and physical measurements are listed separately below. The tool checks its selected settings; image clarity and application acceptance still require review. Adding bytes cannot restore missing detail.

🛡️ Preparation checklist for IIT Kharagpur · JAM 2027
- 1 Sign horizontally inside a 7 cm wide × 2 cm high box on white paper using black or dark-blue ink.
- 2 Use your own full signature, not all-capital lettering or initials. The source asks for a professional scan cropped to the box border.
- 3 Keep every stroke visible. The width-first pixel range is 280 × 80 to 560 × 160; the tool starts at its upper end.
- 4 Check the downloaded JPG is 50–150 KB and legible. Prepare your photo separately using the 50–200 KB photo tool.
❓ Frequently Asked Questions (IIT Kharagpur · JAM 2027)
What are the JAM 2027 photo and signature file sizes? ▼
The official page lists JPG/JPEG at 50–200 KB for a photograph and 50–150 KB for a signature. The old 20 KB photo minimum on this site has been corrected.
Must a JAM signature be exactly 560 × 160 pixels? ▼
No. That is the upper limit, written width first. The lower limit is 280 × 80 pixels. The source describes the signature box and pixel dimensions height first; this tool consistently shows width first.
Why does the photo tool use 420 × 540 pixels? ▼
It is an editable canvas inside the published 240 × 320 to 480 × 640 pixel bounds. Its 7:9 proportions match the separately specified 3.5 × 4.5 cm photograph. The pixel-bound pairs themselves have a 3:4 ratio, so they should not be described as an exact centimeter conversion.
Does compression or padding guarantee JOAPS acceptance? ▼
No. A file can meet the byte-size range and still be unclear, cropped incorrectly or otherwise unsuitable. Inspect your original and the exported image; adding bytes cannot improve missing detail.
Can I reuse a JAM 2026 preset? ▼
Use the preset and official notice for your application year. This page is reviewed for JAM 2027; a previous-cycle preset should not be treated as current guidance.
