Google Mobile Ads SDK supports fixed ad sizes for situations where adaptive banners ads don't meet your needs.

The following table lists the standard banner sizes.

Size in dp (WxH)	Description	Availability	AdSize constant
320x50	Banner	Phones and tablets	`GADAdSizeBanner`
320x100	Large banner	Phones and tablets	`GADAdSizeLargeBanner`
300x250	IAB medium rectangle	Phones and tablets	`GADAdSizeMediumRectangle`
468x60	IAB full-size banner	Tablets	`GADAdSizeFullBanner`
728x90	IAB leaderboard	Tablets	`GADAdSizeLeaderboard`

To define a custom banner size, set your size using GADAdSizeFromCGSize:

let adSize = adSizeFor(cgSize: CGSize(width: 250, height: 250))

GADAdSize size = GADAdSizeFromCGSize(CGSizeMake(250, 250));

Set an ad size smaller than or equal to the device screen size. To determine the maximum screen size on iOS 26 and later, use the UIWindowScene.effectiveGeometry.coordinateSpace property. On iOS 18 and earlier, use the UIWindowScene.coordinateSpace property. For details about size constraints, see Ad request size requirements.
