File size

The limit depends on where the banner runs. These are the limits for this size, and how Sizewright stays inside them.

Animated GIFUp to 150 KB
  • Cut the number of images before their quality: one strong photo weighs less than three.
  • Sizewright subsets the fonts to the letters a banner uses and steps image quality down until each package fits its limit.
  • In animated GIFs Sizewright merges held frames and keeps the photo still when a limit needs it.

Design rules for 250 × 250

Square. Close to square, from 4:5 to 5:4. The most flexible shape: copy and image can stack or sit side by side.

What works

  • Stack in a clear order: headline, image or offer, button, logo.
  • After the image, the headline is the largest thing in the frame. At 200 to 300 pixels wide that means short, heavy words.
  • Keep a margin around everything; a small square fills up quickly.
  • Expect the banner beside the content the visitor came for: one message and a clear button, readable in a second.

Common mistakes

  • Fitting the whole landing page into the banner.
  • A button that reads as decoration instead of something to press.
  • Small text over a busy photo.
  • Copy that only makes sense once the landing page is open.
