Question 1

Why does rust-lang.org's Twitter card show a small image?

Accepted Answer

rust-lang.org sets `twitter:card` to `summary`, which renders the image as a small thumbnail. To get the large hero image format, the meta tag would need to be `<meta name="twitter:card" content="summary_large_image">`.

Question 2

What Twitter card type does rust-lang.org use?

Accepted Answer

rust-lang.org uses the `summary` card type. This renders a small square thumbnail next to the title and description.

Question 3

What Twitter handle does rust-lang.org associate with shared cards?

Accepted Answer

rust-lang.org sets `twitter:site` to `@rustlang`. This handle is shown as attribution next to the card on Twitter.

Question 4

Does rust-lang.org declare image dimensions?

Accepted Answer

rust-lang.org sets `og:image` but does not include `og:image:width` and `og:image:height`. Explicit dimensions let platforms render the preview faster without downloading the image first.
