Minimum pixel size for shared facebook images

Question

I search a lot, but cannot find the minimum height needed to link to facebook sharing to show a thumbnail.

I tried with the logo of my site, but it didn’t work, then I tried with a large image and it worked, but what is the minimum size required?

Answer 1

In the feed channel docs , you have this information:

(...) The URL of the image attached to this post. The image must be at least 200 pixels by 200 pixels. For more information about sizes, see our documentation for maximizing media distribution.

Here you have official information about the “Best Practices Exchange” and you can get more information about other facebook sizes here.
