Choosing Image Dimensions for University Admission Portals

Updated September 3, 2026 · 7 min read

Dimensions decide how sharp an image looks and how heavy it is. Admission systems handle thousands of uploads and often set modest file limits for photos and supporting scans.

Recommended settings for university admission portals

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 800 px on the long edge
Quality70
File size100 KB or less

These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.

Choosing Image Dimensions

Think about the largest size the image will ever be displayed at, then allow a little extra for high-density screens. For university admission portals, about 800 pixels on the long edge covers most cases.

Going much larger gives no visible benefit on screen but costs bandwidth and storage. Going smaller risks a soft look when people view it full screen.
