What size images work best?

Images are the rocket fuel for quizzes – the right pictures can turn an average quiz into an awesomely engaging one.

You can make quizzes in three orientations – wide, tall, or square. Each uses different image dimensions.

We include a ‘crop’ tool – just click on ‘edit’ on any image.

  • Widescreen: sizes like 1280×720 or 1920×1080 naturally work best
  • Square: 1080×1080
  • Tall: 720×1280 or 1080×1920

File size: 250KB is a good target.

(Back story: We automatically compress all images by 80% – which works for most folks. However, if you have some very large files, you might want to speed up your quiz loading times by reducing the overall pixel dimensions and file size. For example, a 400KB file uploaded becomes a 50KB file – but a 4MB file would be 500KB.)

Please note: once you select a format, all of the images will be in that ratio… for example, you can’t mix/match wide with tall images.

This is on purpose – we didn’t want your quiz resizing all the time to accommodate different image layouts.

Animated GIFs: 

GIFs are super popular – and great for engagement. But they’re big files – and they’re slow to load, especially if you’re using several in a single Riddle. (Unless you’re using our new lazy loading option – which also speeds things up.)

All animated GIFs you upload (or use from Giphy) will automatically be converted to MP4 videos (max file size: 7MB).

No loss of quality, and much faster experience, especially for mobile users on slower connections.
