What is the minimum width and height Of Facebook Open Graph Images?

Question

I had read that images associated with a given URL in the Facebook open graph had to be greater than 50 x 50

However, when we ran the Facebook Object debugger - we got the following warning:

"Tiny og:image: All the images referenced by og:image must be at least 200px in both dimensions. Please check all the images with tag og:image in the given url and ensure that it meets the minimum specification."

Our URL is http://www.famousbirthdays.com/people/charlie-chaplin.html and the image does show up under Object Properties

Do we need to convert our images to be greater then 200 x 200? Or can we leave it as is? It is currently a 65 x 75 image.

thanks for your help!

Answer 1

Today I had a much clearer answer to this question (from the Open Graph debugger tool):

Small og:image: All the images referenced by og:image should be at least 200px in both dimensions, with 1500x1500 preferred. (Maximum image size is 5MB.) Please check all the images with tag og:image in the given url and ensure that it meets the recommended specification.

og:image should be larger: Provided og:image is not big enough. Please use an image that's at least 200x200 and preferably 1500x1500. (Maximum image size is 5MB.) Image ... will be used instead.

So, YES, you have to convert your open graph images to at least 200x200 pixels, and it seems that the larger, the better.

If your image is smaller than 200x200, Facebook will try to use a larger image (if) available on the page.

The same information returned by the debugger can be found on the open graph documentation, on "Maximizing Distribution for Media Content" topic, item 3: tags
