What the SBI PO size rules mean
- The SBI PO photo is a portrait, 1.15 times taller than it is wide at 200×230 pixels.
- Its 50KB photo limit is the same as the typical limit across the 12 banking exams on KbSnap.
- The signature box is a wide box (7:3), 2.3 times wider than it is tall at 140×60 pixels, 10–20KB.
Tips for this spec
- The photo must be at least 20KB as well as at most 50KB. A file that is too small is rejected too, so check both numbers in the result before you download.
- A 10KB minimum is high for a signature. Scan or photograph it in good light at full resolution; a tiny, heavily compressed source may not reach the minimum.
Same photo and signature spec: IBPS (PO/Clerk), IOCL Recruitment, SBI Clerk, RBI Grade B, SBI CBO, IDBI Assistant Manager, Bank of India PO, Canara Bank, Union Bank of India, Central Bank of India, RBI Assistant, NICL (AO & Assistant). If you are applying to these too, files made here should also fit — but confirm each notification, since specs change between cycles.
Verify the current requirement on the official SBI PO website before you upload. Sizes can change with each notification.
Common reasons SBI PO uploads are rejected
- A signature in capital letters is not accepted. Sign the way you normally do.
- The handwritten declaration must be in English and black ink, scanned at 800×400 pixels and 50–100KB. It is the largest file in the form, so don't compress it to signature size.
- The photo (200×230 pixels, 20–50KB), signature (140×60 pixels, 10–20KB) and left thumb impression (240×240 pixels, 20–50KB) each have their own minimum as well as maximum size.

How to resize your SBI PO documents
- 1. Upload: choose a clear JPG, PNG, or iPhone HEIC photo or scan.
- 2. Crop: frame your face or signature inside the box shown for each document.
- 3. Process: KbSnap resizes to the exact pixels and compresses into the allowed KB range.
- 4. Check and download: confirm the pass/fail result, then upload the file to the SBI PO portal.

Read →Frequently Asked Questions
What photo size does KbSnap use for SBI PO?
The KbSnap preset for the SBI PO photo is 200×230px, 20–50KB, 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 SBI PO?
The KbSnap preset for the SBI PO signature is 140×60px, 10–20KB. 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 SBI PO signature to 10–20KB?
Upload your scanned signature in the Signature step above, adjust the crop, and process it. KbSnap resizes it to 140×60px and compresses it into the 10–20KB range, then shows a pass/fail check before you download.
Any special rules for SBI PO?
The SBI PO 2026-27 advertisement also asks for a left thumb impression (240×240 pixels, 20–50KB) and a handwritten English declaration in black ink (800×400 pixels, 50–100KB). Signatures in capital letters are not accepted.
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.
