Drupal CMS: Image sizing

Learn about resizing an image for Drupal.

You must ensure that your images have been optimised for the web and resized as JPGs or PNGs, before uploading to your website.

Image sizes

  • site banner: 1400 x 420 pixels
  • full-width image or carousel: min 1200 pixels wide (height will depend on your design)
  • image gallery: 1000 pixels wide (height of images should be consistent)
  • image for the UCL Public Event Calendar: 800 x 500 pixels or as close as possible to this width size on a ratio of 16:10.
  • all other images: 800 x 500 pixels

Remember to optimise your images by saving as JPGs or PNGs at 72dpi and at no higher than 80% quality.
