Optimal Image Size For Social Sharing

[easyrider2]

Hi Everyone, I have just watch Rands latest whiteboard friday and in it he mentions that care should be taken to ensure that images are sized correctly for social sharing on facebook and Google+.

Could anyone expand on what the ideal size for an image should be so that is sizes correctly when shared socially.

Thanks

Here is a good post that tells you how to optimize content for social sharing: http://www.seomoz.org/blog/rock-your-seo-with-structured-social-sharing-mozcon-presentation

The post says: 150x150 square is the best size for both Facebook and Google+. The height must be at least 120px. (If the width is less than 100px, then the aspect ratio must be no greater than 3:1.)

200x200 is a good minimum size, anything less won't always show up.
