Research and my suggestion¶
According to https://blog.bufferapp.com/ideal-image-sizes-social-media-posts and many other sites and the opengraph website I would suggest the following aspect ratios supported out of the box to minimize integration work for every TYPO3 project:
- 1.91:1
- 9:16
- 16:9
- 4:5
- 3:2
- 2:3
- 1:1
- Free/NaN
based on the following overview:

9:16 Sharing Stories: 1,080 x 1,920 pixels*
