Images are key to making your social media posts get noticed. But those images—whether cover photos, profile pics, or visuals in timelines or news feeds—need to be the right type of images. And that means the right size—i.e. image display size.

The problem? Social platforms often change their guidelines on optimal display sizes.

The solution? An infographic by social media marketing and management platform Statusbrew that lays out the various image sizes, together with some tips, for seven of the most popular social media platforms.
