Actual size
Rendered at true pixel dimensions. On a narrow screen it scales down to fit.
Where it runs
Full-screen in landscape orientation, most often in gaming apps.
Why it is used
The landscape counterpart to 320x480, used where the app or content is landscape-locked. Common in mobile gaming, where it appears at natural level breaks.
What to watch for
Needs a portrait counterpart trafficked alongside it, or the unit simply will not serve when a user rotates. Supplying only one orientation is a frequent cause of unexplained under-delivery on in-app campaigns.
File weight for standard display is commonly specified at around 150 KB initial load, but publisher specs vary and the figure that governs is always the one written into the insertion order. Check it before trafficking rather than after a creative is rejected.
