What is the 480×320 Mobile Landscape Interstitial?
The 480 x 320 Mobile Landscape Interstitial is the full-screen standard for users holding their device horizontally. This unit is most commonly seen in mobile games, video streaming apps, and tablet browsing experiences where landscape orientation is natural.
It is the “sister” unit to the 320×480 (Portrait). To run a truly effective mobile campaign, you must have both versions to ensure you capture users regardless of how they are holding their phone.

Best Practices for Design
Since this is a landscape unit, structure your design horizontally. Place your visual on the left and your text/CTA on the right (or vice versa). This “split-screen” structure works best for readability and prevents the design from feeling cluttered.
