YouTube image sizes and dimensions

Each row states the surface, the pixel size, the aspect ratio when the platform prints one, and what kind of figure it is. A minimum, a maximum and a recommendation are different claims, so they are labelled differently rather than flattened into one column.

A platform limit, not a working scheduler

No connector has passed its definition of done. This page states what the platform enforces. It does not say that this product publishes there yet.

How current this is

A platform can change a surface without announcing it. The date beside each source is the day a person last opened that page and read the numbers on it. A reading that goes stale fails a test in this repository rather than sitting here quietly.
