Why 140x60 pixels is the standard signature size
In Indian online application systems - including SSC (Staff Selection Commission), IBPS banking recruitments, UPSC, state police recruitment boards, and university admissions - the standard signature upload specification is almost universally 140 pixels wide by 60 pixels tall, with a file size limit of 10 KB to 20 KB in JPG format.
How to get a sharp signature at 140x60 pixels
- Dark ink on white paper: Sign on clean, unlined white paper with a black or dark blue ballpoint pen. High contrast ensures clear legibility even at 140x60 pixels.
- Crop tightly: Crop away excess white paper around the stroke before resizing so the signature fills the rectangular frame.
- Under 20 KB: Our tool automatically scales and compresses the file so it clears strict 10 KB - 20 KB portal filters without blurriness.
