New og:image size for Facebook share?

Question

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

Answer 1

I'm using the minimum image size (200 x 200) and getting good results. Take a look:

This squared size is better than rectangles because it is the format that appears on facebook comments. The rectangle format gets cropped.

This size is on facebook documentation
