Image sizes and dimensions
One page per platform, listing the pixel sizes that platform publishes for its own surfaces. A surface is here only when the platform states a size for it in its own documentation. Nothing is measured off a screenshot and nothing is copied from a size chart.
這是平台限制，而非正在運作的排程功能
Where these sizes come from
A person opens the platform help centre or developer documentation, finds the sentence that states the pixels, and records the numbers with that page and the date. The limits in the rest of this section are generated from connector code instead. These are not, and that difference is why every row here carries its own source.
Why a surface can be missing
Plenty of surfaces have a size everyone repeats and no platform publishes. Those are absent here. A guess set in the same type as a documented figure would read as a fact, so the rule is the same one the rest of this section follows: no source, no row, no page.
