How to use this reference
9:161 Find your network
Every network we publish to has a card: canvas presets in pixels, the aspect ratios it accepts, and the file limits it enforces.
1:12 Design to the ratio
Ratio matters more than exact pixels. Hit the ratio and the network scales your file without cropping the important part out.
4:53 Check the limits
File size and format limits are the usual reason an upload fails. Caption and hashtag limits are listed alongside them.
16:94 Stop resizing by hand
These are the same presets our editor ships with — pick one, design once, and publish the right crop to every network.
