Best practices

Use high quality images

To make sure image creatives look great on any device, including high-density Retina displays, you can upload image assets that are up to twice the dimensions of your creative. Display & Video 360 will scale down the image based on the resolution of the device where it serves. Display & Video 360 will only scale the image into sizes with the same aspect ratio as the original asset.


To make sure a 300 × 250 creative looks great on screens with higher pixel density, upload a 600 × 500 image and select 300 × 250 as the creative size.

Content requirements

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

File types .jpg, .jpeg, .gif, and .png
Dimensions Maximum 4096 × 4096 pixels
