Recommended Facebook image sizes for 2020:

Pro tip:  

The attention span of the audience is extremely short on social, so try to keep Facebook videos as short as possible. While the maximum video length is 240 minutes, Facebook recommends keeping them as short as 15 seconds. 

A visual network from its inception, Instagram is where marketers can indulge their inner photog and filmmaker. Instagram Stories are catching all the attention lately, but you can still easily win eyeballs with static imagery—one tip here is to employ filters.

Be sure to make use of the three orientations available (square, landscape, and portrait) and compose your photos accordingly. Bear in mind though that this variety also makes using the right Instagram post dimensions crucial.
