Fixed size banner ads

Page Summary

outlined_flag

• The Google Mobile Ads SDK supports fixed ad sizes as an alternative to adaptive banners.

• There are standard fixed banner sizes available, listed with their descriptions, availability, and corresponding AdSize constants.

• You can define custom banner sizes using the GADAdSizeFromCGSize function.

• Google Ad Manager allows for serving any sized ad unit into an app, which should match the dimensions of the GAMBannerView .

• It is possible to specify multiple ad sizes that can be eligible to serve into a GAMBannerView by setting the validAdSizes property and implementing the GADAdSizeDelegate method to detect size changes.

Select platform: Android (beta) Android iOS Flutter

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.

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 
 ));

Custom ad size

In addition to the standard ad units, Google Ad Manager lets you serve any sized ad unit into an app. The ad size (width, height) defined for an ad request should match the dimensions of the ad view ( GAMBannerView ) displayed on the app. To set a custom size, use GADAdSizeFromCGSize .

  // Define custom GADAdSize of 250x250 for GAMBannerView. 
 let 
  
 customAdSize 
  
 = 
  
 adSizeFor 
 ( 
 cgSize 
 : 
  
 CGSize 
 ( 
 width 
 : 
  
 250 
 , 
  
 height 
 : 
  
 250 
 )) 
 bannerView 
  
 = 
  
 GAMBannerView 
 ( 
 adSize 
 : 
  
 customAdSize 
 ) 
 

  // Define custom GADAdSize of 250x250 for GAMBannerView 
 GADAdSize 
  
 customAdSize 
  
 = 
  
 GADAdSizeFromCGSize 
 ( 
 CGSizeMake 
 ( 
 250 
 , 
  
 250 
 )); 
 self 
 . 
 bannerView 
  
 = 
  
 [[ 
 GAMBannerView 
  
 alloc 
 ] 
  
 initWithAdSize 
 : 
 customAdSize 
 ]; 
 

Multiple ad sizes

Ad Manager lets you specify multiple ad sizes which could be eligible to serve into a GAMBannerView . There are three steps needed in order to use this feature:

1. In the Ad Manager UI, create a line item targeting the same ad unit that is associated with different size creatives.

2. In your app, set the validAdSizes property on GAMBannerView :

   Swift

     // Define an optional array of GADAdSize to specify all valid sizes that are appropriate 
    // for this slot. Never create your own GADAdSize directly. Use one of the 
    // predefined standard ad sizes (such as GADAdSizeBanner), or create one using 
    // the GADAdSizeFromCGSize method. 
    // 
    // Note: Ensure that the allocated GAMBannerView is defined with an ad size. Also note 
    // that all desired sizes should be included in the validAdSizes array. 
    bannerView 
    . 
    validAdSizes 
     
    = 
     
    [ 
    NSValueFromGADAdSize 
    ( 
    AdSizeBanner 
    ), 
     
    NSValueFromGADAdSize 
    ( 
    AdSizeMediumRectangle 
    ), 
     
    NSValueFromGADAdSize 
    ( 
    adSizeFor 
    ( 
    cgSize 
    : 
     
    CGSize 
    ( 
    width 
    : 
     
    120 
    , 
     
    height 
    : 
     
    20 
    )))] 
    
   

   Objective-C

     // Define an optional array of GADAdSize to specify all valid sizes that are appropriate 
    // for this slot. Never create your own GADAdSize directly. Use one of the 
    // predefined standard ad sizes (such as GADAdSizeBanner), or create one using 
    // the GADAdSizeFromCGSize method. 
    // 
    // Note: Ensure that the allocated GAMBannerView is defined with an ad size. Also note 
    // that all desired sizes should be included in the validAdSizes array. 
    self 
    . 
    bannerView 
    . 
    validAdSizes 
     
    = 
     
    @[ 
     
    NSValueFromGADAdSize 
    ( 
    GADAdSizeBanner 
    ), 
     
    NSValueFromGADAdSize 
    ( 
    GADAdSizeMediumRectangle 
    ), 
     
    NSValueFromGADAdSize 
    ( 
    GADAdSizeFromCGSize 
    ( 
    CGSizeMake 
    ( 
    120 
    , 
     
    20 
    ))) 
    ] 
    ; 
    
   

3. Implement the GADAdSizeDelegate method to detect an ad size change.

   Swift

     public 
     
    func 
     
    bannerView 
    ( 
    _ 
     
    bannerView 
    : 
     
    BannerView 
    , 
     
    willChangeAdSizeTo 
     
    size 
    : 
     
    AdSize 
    ) 
    
   

   Objective-C

     - 
    ( 
    void 
    ) 
    bannerView: 
    ( 
    GAMBannerView 
     
    * 
    ) 
    view 
     
    willChangeAdSizeTo: 
    ( 
    GADAdSize 
    ) 
    size 
    ; 
    
   

   Remember to set the delegate before making the request for an ad.

   Swift

     bannerView 
    . 
    adSizeDelegate 
     
    = 
     
    self 
    
   

   Objective-C

     self 
    . 
    bannerView 
    . 
    adSizeDelegate 
     
    = 
     
    self 
    ;
