CDS (Combined Defence Services) Photo & Signature Size
CDS is conducted by UPSC, whose upload instructions apply "for any examination" on the portal: a JPG photograph of 20–200 KB with about 75% face coverage, plus a JPG image containing three signatures arranged vertically at 20–100 KB and 350–500 pixels. The instructions publish no fixed photo pixel dimensions, photo aspect ratio, DPI, or name/date strip.

About this exam
CDS is conducted by UPSC through the upsconline.nic.in portal, and the portal's photo and signature instructions apply to every UPSC examination rather than giving CDS its own band. A live photograph is also captured during the application and matched against the uploaded photo. The signature upload must show the candidate's signature three times vertically on one plain-white image.
CDS inherits UPSC's portal instructions
Combined Defence Services candidates prepare a 20–200 KBphotograph and a 20–100 KB signature file under the common UPSC instructions. Both are JPG; UPSC does not publish a fixed photo pixel canvas, aspect ratio, DPI value, or digital name/date strip for this workflow.
Check the CDS preview as its own submission
The CDS form includes UPSC's live-photograph step and expects one signature image containing three vertically arranged signatures on white paper. Even if you also applied for NDA, reopen and review the CDS upload preview and current examination notice; shared technical limits do not mean one application record completes the other.
