Facebook has made it very easy for us to update the Facebook Timeline Cover, which is the main picture at the top of your Facebook page. But, what size needs to be my picture so it fits perfectly in that space? That, unfortunately, is not as easy as it should be.

What’s the issue with Facebook Timeline size?

The problem is that Facebook behaves the same way as any other modern responsive website or app and it resizes automatically to fit either a computer or a mobile device, however, they haven’t implemented an option for you to use two different images for this purpose.

So these days your page’s cover photo displays at:

  • 820 pixels wide by 312 pixels tall on computers and
  • 640 pixels wide by 360 pixels tall on smartphones

Any photo you decide to upload will be cropped to fit the desktop version and when on a mobile stretched to the required height and forced to fit a visible area of 640 pixels wide where the sides of your image won’t show at all. A couple of years ago this was still a viable option when traffic from computers was around 70% of your total visitors but this is not the case anymore. Today mobile traffic represents more than 50% of the total so you simply can’t ignore that fact anymore and upload something that will end up showing badly cropped and blur
