Delhi Police Constable posts are filled through the SSC GD Constable common recruitment exam, and with lakhs of aspirants applying every cycle, the SSC portal is strict about photo and signature specifications — get the size wrong and your form can be rejected before you even sit for the physical test.
Here are the exact numbers you need for your photo and signature upload, based on the latest official SSC GD notification, so you do not lose a shot at this exam over a file-size error. Keep these numbers handy while you are filling the form, since the upload step is where most last-minute panic happens, often on the final day before the application window closes.
Photo Size Requirements
The photograph for your Delhi Police Constable (SSC GD) application should measure 3.5cm x 4.5cm, which works out to roughly 200 x 230 pixels, saved as a JPEG/JPG file between 20KB and 50KB. The background must be a plain, light-colored background — busy or dark backgrounds are routinely rejected. The photo should be recent, taken within the last 3 months, in color, with both ears and your full face clearly visible, and no cap, spectacles, or heavy shadows on your face. Since this is the same form used for other Central Armed Police Forces vacancies, the specification is uniform across the notification, so there is no separate 'Delhi Police version' of the size rules to worry about.
Signature Size Requirements
Your signature should be scanned at approximately 4cm x 2cm (around 140 x 60 pixels), kept between 10KB and 20KB, and saved in JPEG format. Sign in black ink on plain white paper using your normal running handwriting, not block capitals. SSC recommends scanning both the photo and signature at a minimum of 300 DPI for a sharp, clear result. Keep the paper flat and well-lit while scanning or photographing your signature, since a tilted angle or glare can make an otherwise valid signature look distorted once it is cropped to size.
Common Mistakes That Get Applications Rejected
Applicants most often get tripped up by uploading a photo taken years ago that no longer matches their current appearance, using a casual selfie instead of a proper passport-style photo, or forgetting that the SSC portal enforces both a minimum and maximum KB size — a file that is too small gets rejected just like one that is too large. Signing in capital letters, using a shaky or unclear signature, and uploading PNG or PDF files instead of JPG are the other frequent slip-ups that stall an otherwise complete application. A photo cropped from a group picture, or one with another person's shoulder visible at the edge, is also a surprisingly common reason for rejection during scrutiny. Because SSC GD applications are checked in bulk, even a technically valid file that just looks unprofessional, such as one taken in poor indoor lighting, can draw extra scrutiny during document verification.
