As a photographer you can’t just whack a photo onto social media these days and expect it to look on point. Instead knowing the best sizes for images on social media will help you decide what to post, and where.
The sizes for images on social media differ from platform to platform. Getting the same image optimised for Twitter and Instagram for example require different crops to make the most of the native display of the app.
Therefore, you may need 2-3 versions of the same photo to render it at its best. I am going to show you the best sizes for images on social media.

Image: It’s best to crop your images for each social media platform before you upload them. This allows you to decide which images look best in different formats. Some may not work at all.

• Cover Photos (that’s the area at the top of a profile) – 820px x 312px
