1. Official SSC Photo & Signature Specifications Summary Table

The Staff Selection Commission (SSC) strictly enforces biometric formatting for all major examinations, including SSC CGL, CHSL, MTS, GD Constable, and CPO. Any mismatch in resolution, file size (KB), or facial framing results in immediate rejection of the online application.

Document Type Dimension (Width × Height) File Size (KB) Resolution / Format Background / Ink Rules
SSC Candidate Photograph 3.5 cm × 4.5 cm (138 × 177 px) 20.0 KB to 50.0 KB JPG / JPEG (100–200 DPI) Plain White / Light Gray, both ears visible
SSC Candidate Signature 4.0 cm × 2.0 cm (150 × 75 px) 10.0 KB to 20.0 KB JPG / JPEG (100–200 DPI) Pure Black / Dark Blue ink in running hand

2. Key Guidelines for SSC Live Webcam Photo & Uploaded Scans

Under the new SSC One-Time Registration (OTR) portal guidelines, candidates are prompted to capture a live photograph or upload a compliant passport-size image. Follow these non-negotiable rules to pass the automated facial recognition filter:

  • 70% to 80% Facial Ratio: The candidate’s face from the top of the forehead to the bottom of the chin must occupy at least 70% to 80% of the vertical frame.
  • Neutral Expression & Frontal Gaze: Look straight into the camera lens with both eyes open. Smiling with teeth exposed, squinting, or turning the head sideways will cause automated rejection.
  • No Spectacles, Hats, or Caps: Even if you wear prescription glasses daily, SSC guidelines state that tinted lenses, glares, or thick frames must be removed during photograph capture.
  • Both Ears Uncovered: Ensure your hair does not cover your ears, eyebrows, or forehead.

3. The Golden Signature Rules: Running Hand vs. Capital Letters

A staggering 18% of rejected SSC applications are due to improperly scanned signatures. Candidates must keep the following in mind:

  • Never Sign in Capital/Block Letters: Signatures written in capital letters (e.g., "RAHUL SHARMA") are strictly invalid. Only natural cursive/running hand signatures are accepted.
  • Use Plain White Unruled Paper: Do not sign on lined notebook paper, ledger paper, or graph paper. Any grid lines in the background will trigger automated portal errors.
  • Sign with a Black Gel or Ballpoint Pen: Black ink offers the highest scanning contrast when thresholded to 10KB–20KB.

Q: What if my file size is 51 KB or 19.8 KB?

Q: Is Date of Photo (DOP) mandatory for SSC?
A: For recent SSC notifications, date printing is optional unless specifically asked in the tier-specific notice, but the photo must be taken within 3 months of the notification release date.
