RRB NTPC (Graduate) Signature Size 2026

Rules for the signature

• Signature 30–49 KB

  min 140×60 px · JPG · 200 DPI

  • Black ink on white paper
  • Running (joined) handwriting, not block or capital letters
  • At least 140×60 pixels, scanned at 100 DPI or more
  • Centred inside a 35×20 mm box
  • Must match your signature at the exam, DV, medical and joining

  Note: Minimum 140×60 px. At that size a clean signature makes too small a file, so we enlarge it step by step (up to 600 px wide, usually about 600×257 px) until it reaches the 30 KB minimum.

Tip: Sign in running handwriting with a black pen on white paper, inside a 35×20 mm area. Fill the area.

Upload errors and how to fix them

These are the messages the RRB NTPC (Graduate) portal shows. Each one has a fix.

Error: File size should be between 30 KB and 49 KB

Fix: A clean signature is usually 10–20 KB, so it fails the 30 KB minimum. SahiSize first enlarges the image (still at least 140×60), then raises quality, and only then adds invisible padding until it reaches 30–49 KB.

Error: Signature written in BLOCK or CAPITAL letters instead of running handwriting

Fix: This is an official rejection ground. Sign in joined, running handwriting the way you sign a cheque.

Error: Use of non-black ink for the signature

Fix: Blue ink is not allowed for RRB. Sign again with a black pen.
