SSC CGL, CHSL, MTS Photo & Signature Sizing Guide
Official dimensional specifications, Date of Photo (DOP) caption standards, file size limits, and signature guidelines for Staff Selection Commission online application portals.
For SSC examinations (CGL, CHSL, MTS, GD, CPO), the photograph must be a JPEG between 20KB and 50KB with dimensions of 3.5cm × 4.5cm (100×120 pixels minimum, 300 DPI recommended), and the signature must be between 10KB and 20KB with dimensions of 4.0cm × 2.0cm (140×60 pixels minimum).
Why It Matters
Over 10% of preliminary rejections in SSC recruitment drives are attributed to defective photographs and signatures. Automated portal validation algorithms instantly flag uploads exceeding byte limits, while human scrutiny rejects admit card photos that feature spectacles, caps, selfies, tilted heads, inverted orientations, or missing date/name captions when specifically mandated by exam notifications.
Official Dimensional Rules for SSC Photo and Signature
The Staff Selection Commission mandates specific geometric constraints for candidate identity files. The photograph must adhere to a 3.5 cm width by 4.5 cm height portrait aspect ratio. While the minimum system resolution is 100 pixels wide by 120 pixels high, uploading at 300 DPI (approximately 413×531 pixels) guarantees that admit cards print with crystal clarity.
The candidate signature requires a landscape aspect ratio: 4.0 cm in width by 2.0 cm in height (a 2:1 ratio). The minimum allowed pixel dimensions are 140 pixels wide by 60 pixels high. Uploading a square crop of a signature into a 2:1 rectangular frame causes severe horizontal compression, rendering the applicant's handwriting illegible.
- Candidate Photo: 3.5 cm (width) × 4.5 cm (height), 20KB to 50KB, JPG/JPEG.
- Candidate Signature: 4.0 cm (width) × 2.0 cm (height), 10KB to 20KB, JPG/JPEG.
- Color Space: sRGB baseline JPEG without CMYK or progressive encoding.
Date of Photo (DOP) and Name Caption Rules
In specific recruitment cycles, SSC guidelines state that the photograph must not be older than three months from the notification date. When mandated, the candidate's name and the exact Date of Photo (DOP) must be clearly printed in black capital text on a white strip at the bottom of the portrait.
The caption strip should occupy approximately 10% to 15% of the bottom frame, ensuring that the date is distinctly legible without obscuring the candidate's chin or shirt collar. Using ToolMela's Photo Name & Date Stamper allows you to type your name and date directly onto the image with automatic font sizing and baseline alignment.
Capturing and Cleaning Candidate Signatures
A major source of signature rejection is poor contrast. Candidates frequently sign on lined notebook paper or use pale blue ink under dim indoor lighting. The resulting upload has a murky gray background with faint text that fails automated contrast thresholds.
Always sign on unruled, pure white copier paper using a bold black gel or ballpoint pen. When photographing the signature, use ToolMela's Signature Cropper to boost monochrome contrast, converting the paper background to pure white (#FFFFFF) while keeping the ink strokes crisp and pitch-black.

Step-by-Step Workflow
1. Review Exam Notice
Confirm whether the current recruitment cycle requires live webcam capture or static file upload with DOP stamp.
2. Format Photograph
Use ToolMela SSC Photo Resizer to lock 3.5×4.5 cm proportions and 20KB–50KB target file size.
3. Stamp Name & Date
If required, apply a clean white caption strip at the bottom showing your full name and date of photo.
4. Clean Signature
Sign on white paper with dark ink, crop to 4.0×2.0 cm, and compress between 10KB and 20KB.
5. Final Pre-Upload Check
Verify both files on your desktop to confirm exact byte counts and proper orientation.
Professional Best Practices & Pro Tips
- •Always sign with black ink; black ink provides superior optical density compared to blue ink during document digitization.
- •Do not crop too closely around the signature; leave a 2mm white breathing margin on all four sides so pen strokes do not touch the border.
- •Check the photo background under bright light; shadows cast by ears or shoulders can trigger automated background checker rejections.
- •Name the saved files simply as 'photo.jpg' and 'signature.jpg' to prevent portal upload scripts from failing on special characters.
An aspirant filling out the SSC CGL 2026 application form received repeated portal error alerts because their smartphone portrait was 1.4MB and their signature photo was 85KB. Using ToolMela's SSC Photo & Signature Resizer, they cropped the portrait to 3.5×4.5 cm at 34KB, stamped the current month's DOP, and converted the signature scan into a crisp 14KB JPEG at 4×2 cm, successfully submitting their application on the first attempt.
Common Mistakes to Avoid
Technical Realities & Limitations
Recent SSC portal versions utilize live webcam capture for certain exam stages; ensure your computer webcam is functioning in good lighting if static upload is replaced.

Frequently Asked Questions
Is Date of Photo (DOP) mandatory for all SSC applications?
Always review the specific official notification for your recruitment year. Some exam cycles require a DOP printed on the photo, while others mandate live webcam capture without stamping.
Can I wear spectacles in my SSC application photo?
No. SSC guidelines strictly prohibit eyeglasses, spectacles, and sunglasses in uploaded photographs to ensure unobstructed facial recognition.
What should I do if my signature file is below 10KB?
If your signature is under 10KB, increase the pixel dimensions or adjust the JPEG quality setting in ToolMela Signature Resizer to keep it comfortably between 10KB and 20KB.
Why does the SSC portal reject PNG format photos?
The SSC server-side validation script strictly accepts files with .jpg or .jpeg extensions and MIME type image/jpeg; PNG and PDF formats are rejected.
Can I sign in capital letters for SSC exams?
No. Signatures in full capital or block letters are strictly prohibited and will result in application rejection. Sign in running handwriting.
