Fixed size banner ads

The 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	BANNER
320x100	Large banner	Phones and tablets	LARGE_BANNER
300x250	IAB medium rectangle	Phones and tablets	MEDIUM_RECTANGLE
468x60	IAB full-size banner	Tablets	FULL_BANNER
728x90	IAB leaderboard	Tablets	LEADERBOARD

The size of the container in which you place your ad must be at least as big as the banner. Any padding effectively decreases the size of your container. If the container cannot fit the banner ad, the ad isn't shown and the following warning is logged:

W/Ads: Not enough space to show ad. Needs 320x50 dp, but only has 288x495 dp.

Custom ad size

If you have Ad Manager reservation line items targeting a custom size, you can create an AdSize with a custom width and height that matches your line item.

Kotlin

val customAdSize = AdSize(250, 250)
val adRequest = BannerAdRequest.Builder(AD_UNIT_ID, customAdSize).build()

Java

AdSize customAdSize = new AdSize(250, 250);
BannerAdRequest adRequest = new BannerAdRequest.Builder(AD_UNIT_ID, customAdSize).build();

Multiple ad sizes

If you want to target line items of multiple ad sizes in the same ad request, create a request with a list of ad sizes.

Kotlin

val adSizes = listOf(AdSize(120, 20), AdSize.BANNER, AdSize.MEDIUM_RECTANGLE)
val adRequest = BannerAdRequest.Builder(AD_UNIT_ID, adSizes).build()

Java

List<AdSize> adSizes =
    Arrays.asList(new AdSize(120, 20), AdSize.BANNER, AdSize.MEDIUM_RECTANGLE);
BannerAdRequest adRequest = new BannerAdRequest.Builder(AD_UNIT_ID, adSizes).build();
