Optimizing Facebook Images Like a Pro

More and more, Facebook users access their accounts using their mobile devices. That is why it is best to use image sizes that are optimized not jut for the desktop, but also for mobile. Otherwise, your Facebook photos will be cut off at unexpected areas, stretched unattractively, automatically centered or rendered as a thumbnail. This can make your page look unprofessional and unappealing.

It helps to know the basics on Facebook image dimensions to make profile pictures and ads look their best. Here are some things to remember for Facebook images and their minimum upload sizes:

  • Cover photo (851 x 315 pixels). It is highly recommended that you use a PNG file for company logos and a JPG or RBG (or products or brochure images. The cover photo should at least be 100 KB in size, with a minimum 399 x 150 pixels. Otherwise, a smaller size will be stretched. Take note that for mobile devices, this image displays at a width of 563 pixels.
  • Profile photo (180 x 180 pixels). Design a profile photo that you can use for all social media platforms aside from Facebook (Twitter, Instagram, Google+, etc.) so that you present a consistent look. When using logos, remember that the profile picture will also be displayed as a thumbnail at 32 x 32 pixels when you like or comment on Facebook. It is ideal to first crop the photo that you want displayed, resize it to 360 pixels square and then save this at the highest quality JPEG file.
  • Posted images. The optimal, for your posted pictures to maintain a high-quality look is 1200 x 1200 pixels. The display will show at a maximum 504 pixels width, with height varying. Posting narrow images will result in gray space on the sides.
  • Images of Facebook shared links. This is also optimized at 1,200 x 630 pixels, with an aspect ratio of 1.91: 1 (width: height). It is best to post your image and then pair it with a link (for example, to your blog, to a product or to your website). Images that are smaller than 600 x 315 will be shown as a thumbnail.
  • Posted events or ads (1200 x 444 pixels). This will automatically scale to fit the longest edge available, depending on the device used. Facebook automatically crops the sides for pictures with a wider proportion. If you include any text inside the image, be sure that the text content is not more than 20% of the total image size. For events, it is also useful to keep the lower left portion of the image simple, as this is where Facebook will display details of the event (such as the tile and date).
