What the India Post GDS size rules mean
- The India Post GDS photo is a portrait (4:5), 1.25 times taller than it is wide at 320×400 pixels.
- Its 100KB photo limit is more generous than the typical 60KB across the 14 central government exams on KbSnap (4 of 14 allow a larger file).
- The signature box is a wide box (5:2), 2.5 times wider than it is tall at 300×120 pixels, 20–100KB.
Verify the current requirement on the official India Post GDS website before you upload. Sizes can change with each notification.

Frequently Asked Questions
What photo size does KbSnap use for India Post GDS?
The KbSnap preset for the India Post GDS photo is 320×400px, 30–100KB, in JPG format. Confirm these numbers in your current notification before you upload, and aim for the middle of the KB range so a re-save does not push the file over the limit.
What signature size does KbSnap use for India Post GDS?
The KbSnap preset for the India Post GDS signature is 300×120px, 20–100KB. Sign on plain white paper in the ink colour your notification asks for (black is the safest choice) and crop tightly so the signature is clearly readable.
How do I reduce my India Post GDS signature to 20–100KB?
Upload your scanned signature in the Signature step above, adjust the crop, and process it. KbSnap resizes it to 300×120px and compresses it into the 20–100KB range, then shows a pass/fail check before you download.
Is my photo uploaded to a server?
No. Cropping, resizing, and compression all happen in your browser using the Canvas API. The file never leaves your device.
Why do different exams need different sizes?
Each exam body sets its own portal validation rules independently — there's no shared standard across UPSC, SSC, banking, and state PSCs.
