Photo & Signature Size for Government Job Forms

A rejected photo or signature is one of the most avoidable reasons a government job application fails — and it happens to thousands of candidates every cycle, usually in the last-minute rush before the closing date. The fix is simple: get your images into the correct format, dimensions and file size before you open the form.

Below are the common specifications used by the big recruiters — SSC, UPSC, the banking exams (IBPS and SBI) and the railways (RRB) — followed by how to resize an image to fit and a checklist of what gets photos rejected. One rule applies everywhere: the exact numbers can change from one notification to the next, and the official notice plus the on-screen upload instructions always take priority over any general guide.

The general rule before the specifics

Almost every central recruiter wants a recent colour passport-style photograph on a plain light or white background, and a signature done in black ink on white paper in your normal running hand. Both are uploaded as JPG/JPEG files — not PNG, PDF or WhatsApp-compressed images. Keep one clean copy of each ready and reuse the same images across the application, the admit card and document verification, because a mismatch later can cause problems.

Photograph — typical specifications by exam

• SSC: JPEG, about 20–50 KB, roughly 3.5 cm × 4.5 cm (~200 × 230 px), light background. SSC notifications have often required the date the photo was taken to be printed on it — some recent notifications relaxed this, so check your notice.
• UPSC: JPG, about 20–300 KB, between 300×300 and 1000×1000 px, plain white background with the face filling most of the frame. UPSC now also asks for a live (real-time) photo capture and a scanned photo ID in the application form.
• IBPS / SBI (banking): JPG/JPEG, about 20–50 KB, ~200 × 230 px, passport-style on a light background.
• RRB (railways): JPEG, commonly 30–70 KB (varies by notification), ~320 × 240 px, recent colour photo, no cap or sunglasses.
• State PSCs (UPPSC, BPSC, MPSC, Kerala PSC, etc.): dimensions and KB limits vary a lot between states — always read that state's notification rather than assuming a central spec.

Signature — typical specifications

• Format: JPG/JPEG, signed in black ink on plain white paper, then scanned or photographed.
• File size: usually about 10–20 KB (RRB and some others allow a little more).
• Dimensions: commonly around 140 × 60 px (4 cm × 2 cm). UPSC asks you to sign three times, one below the other, in a single image.
• Sign in your normal handwriting — signatures in BLOCK or CAPITAL letters, or typed/digital signatures, are routinely rejected.

Extra uploads some exams ask for

Banking exams (IBPS and SBI) usually need two more images beyond the photo and signature:

• Left thumb impression — JPG, about 20–50 KB, ~240 × 240 px, left thumb in black or blue ink on white paper.
• Handwritten declaration — JPG, about 50–100 KB, written in your own hand in black ink (not capital letters), matching the exact text printed in the notification.

How to resize an image to the right size

Most oversized files are oversized because the dimensions are too big — so fix the pixel dimensions first, then bring the file size down. You do not need paid software:

• Windows: open the image in Paint, use Resize to set the pixel dimensions, then Save As JPEG.
• Mac: open in Preview, use Tools → Adjust Size for the pixels, then Export as JPEG and lower the quality slider until the KB fits.
• Free tools like IrfanView or GIMP let you scale to exact pixels and export JPEG at a chosen quality percentage.
• To hit a KB target, nudge the JPEG quality down gradually — but stop before the image turns blurry or blocky, because a degraded image is itself a rejection reason.

Why photos and signatures get rejected

• Wrong format (PNG, PDF or WEBP where only JPG/JPEG is allowed).
• File size outside the allowed band — too large, or sometimes too small.
• Coloured, patterned, dark or shadowed background instead of plain light/white.
• Blurry, pixelated or heavily compressed images (often from forwarding via WhatsApp).
• Wearing a cap or sunglasses, or the face not filling enough of the frame.
• Signature in capital/block letters, typed, or too faint.
• For SSC: missing the printed date on the photo when that notification requires it.
