Determining actual height of an Admob SmartBanner in Unity for Android

Question

So I'm implementing admob banners into my Unity 4.6 Android game. I have the banner at the bottom and need to account for it in my UI. Specifically I need to know exactly how tall it is, but I'm having trouble with figuring this out.

Based on the information found here the Smart Banner should be 32, 50, or 90 pixels tall, depending on device height. This doesn't seem to typically be the case though.

Some searching would seem to indicate this is because of density pixels. So I attempt to convert the stated pixel height using px = dp * (Screen.dpi/ 160). So for example if I determine the banner height should be 90 pixels, I would use bannerHeight = 90 * (Screen.dpi / 160). This seems to work on some devices but not others.

For example my Nexus 4 has a DPI of 320. Using the above it would seem to indicate that the banner should be 180 pixels tall, but the banner appears to actually be about 90 pixels tall. But on the Nexus 7 (which has a dpi of 166), the banner appears to be about 120 pixels tall when the formula would indicate it should be ~93.

So I guess I have no idea how to figure out how tall the banner is actually going to be, and I haven't found a way to get this information from the API. My code for calling the banner is pretty stock:

 string adUnitId = "my_id";

 BannerView bannerView = new BannerView(adUnitId, AdSize.SmartBanner, AdPosition.Bottom);
 AdRequest request = new AdRequest.Builder().Build();
 bannerView.LoadAd(request);

First you need to calculate which Ads google will give you (32 or 50 or 90 ?) for this you can calculate it by screen sizes.

height/dpi = actual height in inches

so, Google says above 720 (with dp of 160dpi) is acctauly 720/160 = 4.5 inch height, above this height, the ads are 90 pixels (dp!) below its 50 dp! 400/160 = 2.5 , below this, ads will be 32 dp

SO! if i have Xiaomi mi3 with 1920x1080 thats, 1920/480dpi = 4 inch height..which will give us 50 dp ads.

with the formula of converting DP to pixel

px = dp * (Screen.dpi/ 160)

50 * (480/160) = 150 pixels height for the ad!

For landscape you need to use as "height" 1080 instead of 1920 1080/480dpi = 2.25 height in landscape this means the ads will be 32 pixels dp

which converts to:

32* (480/160) = 96 pixels in landscape

its too bad google doesn't give enough examples so we can really check ourselves.
