UPPSC recruits for the PCS, RO/ARO, and dozens of other posts through its One Time Registration (OTR) system, and because this platform is shared across many UP government exams, getting the photo and signature specifications exactly right matters even more — a mismatch can affect every future form you fill using the same OTR profile.
Below are the photo and signature specifications you need for UPPSC applications as per the latest official notification, along with a note on the composite-image format some UPPSC notifications still use, so you upload the right kind of file for the specific post you are applying to.
Photo Size Requirements
For most current UPPSC applications, your photograph should be 3.5cm x 4.5cm in size, saved as a JPG/JPEG file between 20KB and 50KB, scanned at a minimum of 200 DPI in true color. Use a plain, light background, and make sure the photo is recent, with your face clearly visible and no blur or shadows. Some older or post-specific UPPSC notifications, such as RO/ARO, instead ask for a single composite image, your photograph pasted on white paper with your signature underneath, scanned together as one 5cm x 6cm file, so always cross-check the specific notification PDF for the post you are applying to before uploading. This is one of the few exams where the format genuinely varies by post, so treat the numbers here as the standard OTR baseline and confirm against your notification if anything looks different.
Signature Size Requirements
When uploaded separately, your signature should be around 3.5cm x 1.5cm, saved as JPG, and kept between 10KB and 20KB, scanned at 200 DPI. Sign in full, in your normal running handwriting — UPPSC is clear that initials and capital-letter signatures are not acceptable. Whatever signature you upload should be the same one you use throughout the recruitment process, from the application form to the admit card and document verification. Since your OTR profile is reused across future UPPSC exams too, it is worth keeping a properly sized master copy of both files saved for quick reuse.
Common Mistakes That Get Applications Rejected
Because UPPSC's OTR profile carries over to multiple exams, the biggest mistake is uploading a photo or signature once and never updating it, even after it becomes outdated or was accepted under looser rules for an older exam. Other common errors include not checking whether a specific notification wants a composite photo-plus-signature scan versus separate uploads, using a colored or busy background, signing in capital letters, and uploading files that are too large because they were never compressed after scanning. Some candidates also assume their old UPSC or SSC-format photo will work for UPPSC, only to have it bounce back for not matching the OTR-specific dimensions.
