Do I need these if I already have Open Graph tags?

Mostly not. X falls back to og: tags, so twitter:card to choose the layout is often enough. The full set matters only if you want different content on X.

What is the difference between the card types?

summary_large_image shows a wide picture above the text. summary shows a small square thumbnail beside it.

Why does my card not appear?

Usually a relative image URL or a cached preview. Absolute URLs and the platform's card validator resolve nearly all cases.

About this tool

Twitter cards work like Open Graph but with their own tag names, and the card type decides the shape: summary_large_image gives the wide picture most people want, while summary gives a small square thumbnail beside the text.

They are not usually needed on their own. X falls back to Open Graph tags when Twitter-specific ones are absent, so if you already have og: tags you mostly need twitter:card to choose the layout. Adding the full set is only worth it when you want different text or a different image on X than elsewhere.

Account names need their leading @, and the image should be an absolute URL for the same reason it must be in Open Graph.

Common uses

Making links show a large preview image on X.
Attributing posts to a site or author account.
Setting different preview text on X than elsewhere.
