New og:image size for Facebook share?
Facebook recently changed image sizes for ads, and link posts. This affects also to meta property="og:image". What is new optimal size for og:image at Facebook? The old version was square, now it doesn't fit anymore, because new size is rectangle.
Answer
EDIT: The current best practices regarding Open Graph image sizes are officially outlined here: https://developers.facebook.com/docs/sharing/best-practices#images
There was a post in the Facebook developers group today, where one of the FB guys uploaded a PDF containing their new rules about image sizes – since that seems to be available only if you’re a member of the group, I uploaded it here: http://www.sendspace.com/file/ghqwhr
And they also said they will post about it in the developer blog in the coming days, so keep checking there as well
To summarize the linked document:
- Minimum size in pixels is 600x315
- Recommended size is 1200x630 - Images this size will get a larger display treatment.
- Aspect ratio should be 1.91:1
