Fixed size banner ads

AI-generated Key Takeaways

The Google Mobile Ads SDK offers fixed ad sizes as an alternative to adaptive banners, providing specific dimensions for different ad formats.
Developers need to ensure the container size is sufficient to display the chosen ad size to avoid warnings or ad display issues.
AdViews can be integrated directly into XML layouts by specifying the desired ad size and the ad unit ID.
Standard banner sizes like Banner (320x50), Large Banner (320x100), and IAB Medium Rectangle (300x250) are available for both phones and tablets, while IAB Full-size Banner (468x60) and IAB Leaderboard (728x90) are primarily for tablets.

Select platform: Android iOS Flutter

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.

Add AdView to the layout

Alternative to creating the AdView programmatically, add the AdView to the XML layout for the Activity or Fragment in which you'd like to display it. Here's an example:

<com.google.android.gms.ads.AdView
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:id="@+id/banner_ad_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_alignParentBottom="true"
    ads:adSize="BANNER"
    ads:adUnitId="ca-app-pub-3940256099942544/6300978111" />

Note the following required attributes:

ads:adSize: Set this to the ad size you'd like to use. If you don't want to use the standard size defined by the constant, you can set a custom size instead. Example: ads:adSize="320x50".
ads:adUnitId: Set this to the ad unit in your app where ads are to be displayed. If you show banner ads in different activities, each would require an ad unit.
