With so many different social media platforms out there, it can be hard to navigate what image sizes you should be using for different profiles and posts. Use a 2020 image size guide to use as a handy reference to create the greatest impact with your social photos.
Aside from cover photos, keep in mind that these are the minimum dimensions for profiles and photo posts, so it would be best to have your images above these guidelines, especially when it comes to profile photos so they don’t get pixelated when you click into them to see them fullscreen. (For example, on Facebook your profile image must be at least 180 x 180 pixels, but something like 1080 x 1080 would look better for overall image quality.)
