What size should an Open Graph image be?

1200 by 630 pixels, a 1.91:1 ratio, works across LinkedIn, Facebook, Slack and X. The checker downloads your image and checks it against each platform's limits.

Why does my link still show an old preview?

Platforms cache link previews. After fixing your tags, refresh the cache with the platform's own tool, such as LinkedIn's Post Inspector or Facebook's Sharing Debugger.

Does X need its own twitter: tags?

X reads twitter:card to choose the card layout and falls back to og:title, og:description and og:image when the matching twitter: tags are missing.
