Why 300×80 pixels is the standard signature dimension
300×80 px is the de-facto standard signature dimension for online government forms and exam registration portals. At this size, a signature is wide enough to be legible but compact enough to fit within standard form field display areas used by portal developers across India's government exam ecosystem (IBPS, SSC, UPSC, state PSC portals).
The 300 px width matches typical form field widths in these systems, and the 80 px height accommodates most handwritten signature heights without excessive whitespace. The ratio was likely established by early government portal developers and has propagated across the ecosystem as a default requirement.

Tips for 300×80 signature resizing
- Use JPG output — exam portals usually require JPG for signatures. JPG at 300×80 also gives the best file size control for the 10–20 KB range these portals typically enforce.
- Crop before resizing — crop your scanned signature to a wide flat rectangle, removing excess white space at top and bottom, before setting the 300×80 dimension. This prevents the signature from appearing squished.
- White background is required — most government exam portals display signatures on white form backgrounds. A coloured or grey background will fail portal validation.
- Set file size target after dimensions — resize to 300×80 first, then use the KB slider to compress within the portal's file size limit (typically 10–20 KB).
