What Is the Max Image Size on Facebook?
Note: See my updated post about the max image size on Facebook. As the comments suggest, there have been some changes to Facebook’s image sharing the photo sizes have changed.
Facebook sets limits on the size of the images it displays. While you can upload bigger photos, Facebook’s upload script will automatically shrink the images and resize them for you. If you want some control in that resizing process, it helps to know what the maximum size is so that you can shrink the images yourself.
The old limit used to be 604px to a side. In March 2010, Facebook announced that the size limit had increased. There is currently a maximum length of 720 pixels on each side. The largest an image could be, then, is 720px x 720px. If your images are still cropped to the standard 4×6 (2×3) aspect ratio, then this means the longer side will be 720px and the shorter side will be 480px.
