In 2012, Facebook introduced Timeline – a revamped look for Facebook profiles and Facebook pages. With the introduction of Facebook Timeline, Facebook dimensions changed. In addition, this gave page owners a lot of new sizing options like Facebook milestones, Facebook highlighted posts, and the Facebook timeline cover photo.

To help you out, I put together this Facebook dimensions infographic for Facebook Pages. This infographic contains all of the sizes and dimensions that you need for your Facebook Pages to present your content to fans.
