About this tool
At 1200 by 630 pixels (about 1.91:1), the landscape Facebook post shares its shape with link previews, so one image can serve as both a feed post and the preview for a shared URL. It is the natural size for event announcements, blog promotions and ads that also run as link posts. Cropping here produces that 1.91:1 landscape frame, the shape Facebook also uses for link previews - so the same export can be your feed post and your OG image.
How to use this tool

One image for posts and link previews
When you share a link, Facebook pulls the page's Open Graph image, usually shown at this 1.91:1 shape. Designing your feed graic and your OG image at 1200 x 630 keeps them consistent. Keep text modest - large blocks of text on images tend to perform worse - and leave margins because previews may be shown smaller in comments and Messenger.
