Facebook aspect ratio and sizes are basically the most important things you need to know to make the most of Facebook’s full reach and power, and you can do that with our calculator! Before publishing any photo or video, use our tool and finally find out the exact sizes!
In short these are the standard sizes. Given the examples above, we certainly recommend using larger sizes in the profile images, for example, to work perfectly well on all devices and keeping the aspect ratio.
As each mobile device currently has a different screen size and resolution, it’s most recommended use larger sizes in the correct aspect ratio. Some aspect ratios are standard on many social networks, such as 16:9 for landscape videos.
