The size each network recommends, in pixels, for the formats we publish. The file cap and the longest video come from the same registry the composer uses to warn you before you post.

How to use it

Pick a network in the filter, or leave it on All to compare them side by side.
Export your image or video at the size in the row, or at least in the same ratio.
Check the file and length columns before you upload: the network rejects a file over the cap.
