New image ad sizes
Hi @Liam H,
The three ad sizes you really want to make sure you are using would be:
- Leaderboard: 728 x 90
- Inline rectangle: 300 x 250
- Large mobile banner: 320 x 100
With that said, if you want to ensure your ads are streamed for the most use, you would want all ad sizes. There are different sizes to consider based on the type of ad, which you can learn about here.
You could consider what Google AdSense has to say, since that is what it used by Google Partner Sites to display ads on properties.
