Metadata OGP.ME What is the ideal image size for social networks

Question

I use the metadata of The Open Graph Protocol for sharing social networks, in particular Facebook.

<meta property="og:image" content="http://example.com/ogp.jpg" />
<meta property="og:image:secure_url" content="https://secure.example.com/ogp.jpg" />
<meta property="og:image:type" content="image/jpeg" />
<meta property="og:image:width" content="400" />
<meta property="og:image:height" content="300" />

Until then I do not define the image size property="og:image:height", but in the Debugger from Facebook says it is recommended to set the image size. Do you have any idea what the ideal size for this image is? Is there any documentation that explains?

Answer 1

According to the good practices on Facebook, the recommended image is to have at least 1200x630px to be better displayed on high resolution devices.

The recommended minimum for a long time is 200x200, but it is already a little outdated for the new layouts and display forms. Now Facebook recommends 600x315px as a minimum. The size of the used image that will designate the shape of the post on the user’s wall and the size of the network reach.

Another important recommendation is to keep your images as close as possible to Aspect reatio 1.91:1 to display the full image in the News Feed without any hack.

According to https://stackoverflow.com/a/15898292/894546, there is a recommendation next to what I would say:

• Use a square image (no consensus, but using square will work)
• Try using multiple values of 100, such as 200x200 (minimum), 300x300 and 400x400 (all in px)
• Avoid very small (100x100) or very large sizes
