Common image dimensions

This post records the image dimensions for common devices or image formats

Scott Bourne’s Photofocus blog reports that the ideal size for images on the new iPad is “2048-by-1536-pixel resolution at 264 pixels per inch (ppi)”. So that’s how you size wallpaper (or portfolio) images.

… and a Mashable article covers Twitter backgrounds, recommending dimensions of 1600px x 1200px. Another article by Christina Warren gives more detailed information on customising your twitter background.

AskeDee reports that Facebook cover images should be 851px x 315px.

Note: I’ll be editing this post as more common dimensions become available. If you’ve any you think should be added, please let me know through the comments.
