Use high quality images

To make sure images look great on any device, including high resolution screens, upload image assets that are up to twice the dimensions of your creative. Display & Video 360 scales images based on the resolution of the device where your ad appears. The image will stay the same shape, even when it's resized to fit different screens.

Example

To make sure a 300 × 250 creative looks great on high resolution screens, upload a 600 × 500 image and select 300 × 250 as the dimensions.

Content requirements

To run on Display & Video 360, all creatives must follow the creative content and policy guidelines.
