matrix.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.

matrix.org's social headline is "Matrix.org" (10 characters).

Question 6

What's the biggest issue with matrix.org's Twitter / X preview?

Accepted Answer

Missing og:type tag. Platforms default to "website" but explicitly setting it ensures correct rendering.
