Choosing Image Dimensions for Landing Pages

Updated July 1, 2026 · 7 min read

Dimensions decide how sharp an image looks and how heavy it is. Landing pages live or die by load speed, and images are usually the heaviest part of them.

Recommended settings for landing pages

SettingStarting point
FormatJPEG (WebP where accepted)
Widthabout 1600 px on the long edge
Quality70
File size150 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 landing pages, about 1600 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.

FAQ

What JPEG quality should I use for e-learning courses?

Quality around 78 keeps photos looking natural while cutting file size substantially.

Will compressing reduce image quality for e-learning courses?

Some detail is removed, but at sensible settings the difference is not visible at normal viewing size.

How do I compress many images for e-learning courses at once?

Drop all of them into the tool together and use Download all to get a single ZIP.

Wrapping up

For landing pages, the reliable recipe is simple: resize to around 1600 pixels, compress at quality 70 or to a 150 KB target, and check the result before you upload. Keep the original so you can always start again.
