Nice, thank you :)

wow, nice hard work and research. Thanks a lot

I think something may have changed with Facebook's preview strategy. Any og:image resource that's an exact square will be cropped into landscape format if the image is at least of a certain pixel width. I don't know at what width Facebook changes the display strategy, but I have a square image at 300x300 and it's displayed in full as a thumbnail inline with my text preview. If that image is bumped up to 1000x1000, Facebook crops it down to a landscape image and displays that instead.

Thank you so much. This comment solved my problem.

Hello - I have an image which users can share using Facebook or Pinterest.
I have set the image size to 1200 x 630 for Facebook using the Open Graph tag. Is there any way to force Pinterest to use a separate portrait image as they both use the same OG tag?
cheers

Wish this factoid also contained information about file type

Apple uses png here https://developer.apple.com...

Thanks! One point - is the ideal resolution 72 or 144 pixels/inch? Oh, hang on (bit of research) it does not matter: https://www.photoshopessent...

since most traffic is mobile, why wouldn't you set ALL open graph images to either square or 4:5?

landscape open garph images look like crap on mobile when you share

Still super helpful 2 years later, thank you! Have you by chance taken a recent peek to see if images have gotten larger for purposes of retina?

Nice ! I'm glad I stumble on this page. I'll take this occasion to say hi! Hope everything's good since we last met in Switzerland ;)

nice info......... Thanks......

Hi Matt, thanks for the great infos here.
Just one question: what about the weight of the OG image? Can I load it full and the "Socials" will always pick it up? Thanks!

Amazing! Love this!

Great analytics, thanks!

Given the arbitrary nature of decisions taken by different designers, i expect some outliers in your data. Thus a median may be a more robust statistic than the mean (average) that you reported. If you can easily compare them it would be interesting to see a comparison of mean, mode, and median just to see how they line up.
