Card details
Live previewWhat the previews need
- Image size: 1200×630 pixels displays well on every network. The minimum is 600×315.
- Image format: PNG or JPG, under 5MB.
- Title length: under 60 characters avoids truncation on X.
- Description length: 150–200 characters. Facebook shows up to 300; X shows less.
- Text on images: large and high-contrast, since most shares are read on phones.

Frequently asked questions
Why does a social network show an old image?
Networks cache Open Graph data. After changing your tags, ask each network to fetch the page again with the Facebook Sharing Debugger or the LinkedIn Post Inspector; X refreshes its cache on its own after about a week.
What is the difference between Open Graph and Twitter Card tags?
Facebook, LinkedIn and most other sites read Open Graph (og:) tags. X reads them too but uses its own twitter: tags when present, so include both.
Do I need a different image for each network?
No. One 1200×630 image works across X, Facebook and LinkedIn.
