# OG Image Size
An incorrectly sized og:image is displayed poorly or not at all on social platforms—Facebook, Twitter/X, LinkedIn each crop or skip images that don't meet their requirements, resulting in blank or distorted link previews.
## Quick Reference
- og:image should be 1200×630 pixels (1.91:1 aspect ratio)
- Minimum size is 600×315 pixels; smaller images may not display
- File size should stay under 5 MB; under 1 MB is preferred
- Use JPEG or PNG; WebP has limited support on older platforms
## Check
Find the og:image meta tag in <head> and fetch the image URL. Check the image dimensions and file size. Flag if width < 1200px, height < 630px, aspect ratio differs significantly from 1.91:1, or file size exceeds 5 MB.
