UPSC OTR Photo & Signature Guidelines 2026 (Civil Services & NDA)
A detailed breakdown of UPSC One Time Registration (OTR) specifications, explaining the mandatory 1:1 square aspect ratio, 10-day recency window, and name/date imprinting.
The Strict 1:1 Square Format Mandate (350 × 350 Pixels)
Unlike most recruitment boards that use standard 3.5×4.5 cm rectangular portraits, the Union Public Service Commission (UPSC) mandates an exact 1:1 square aspect ratio for both candidate photograph and signature uploads.
The minimum resolution required is 350 × 350 pixels, and the maximum is 1000 × 1000 pixels. The file weight must be between 20 KB and 300 KB in JPG format.
- Ensure your face occupies at least 75% of the total square frame.
- The candidate full name and date of photo capture must be printed along the bottom edge of the photo.
The 10-Day Photograph Recency Rule
UPSC rules state that the photograph must not be older than 10 days from the date of the online application commencement.
The candidate appearance (e.g., beard, mustache, hairstyle, spectacles) on examination day must match the photograph uploaded in the OTR profile.
