Other supported ad sizes

Ad size Description Text ads Display ads Mobile text and display ads*
320x50 Also known as the "mobile leaderboard". This format is a mobile-optimized banner.

These ads fill the width of a smartphone screen (e.g., iPhone, Android, BlackBerry6 etc.).
   
320x100  Also known as the "large mobile banner". Can be used an an alternative to the 320x50 and the 300x250.

These ads offer advertisers twice the height of our standard "mobile leaderboard".
   
468x60 Also known as a "banner". This format can fit into smaller spaces that don't accommodate the 728x90 leaderboard. 

The supply of available display ads for this ad size is generally limited though, which may lead to sub-optimal ad performance.
 
234x60 Also known as a "half banner". This format can fit into small spaces.

This size doesn't tend to perform as well as others due to its small size and limited supply of available display ads.
 
120x600 Also known as a "skyscraper", this format can fit into narrower spaces that don't accommodate the 160x600 wide skyscraper.

The supply of available display ads for this ad size is more limited though, which may lead to sub-optimal ad performance.
 
120x240 Also known as a "vertical banner", this format can fit into small spaces. 

This size doesn't tend to perform as well as others due to its small size and limited supply of available display ads.
 
300x600  Sometimes referred to as a "half page". This format provides a larger space for advertisers to get their message across and can offer users rich engagement. 

The 300x600 is one of the fastest growing sizes by impressions and is indicative of a trend where publishers are offering more visually impactful ad sizes that are preferred by brand advertisers.
 
970x90  Sometimes referred to as a "large leaderboard." This ad format expands to 970x415 while politely "pushing" all page elements downwards. The first user impression delivers an auto-initiated pushdown experience. All subsequent impressions deliver a user-initiated pushdown which expands via a user click.

This size is ideal to showcase High-Definition content such as videos, photos, animations, and applications. 
 
250x250 Also known as a "square", this format can fit into smaller spaces that don't accommodate the larger rectangles. 

The supply of available display ads for this ad size is generally limited though, which may lead to sub-optimal ad performance.
200x200 Also known as a "small square", this format can fit into smaller spaces that don't accommodate the larger rectangles. 

The supply of available display ads for this ad size is generally limited though, which may lead to sub-optimal ad performance.
