Google introduced new rounded formats to customize the Adsense ads. Now along with customize colors and size you can also use 2 new rounds shapes. You can now choose between “square corners” (as before), but also “slightly rounded” as well as “very rounded” when customizing your ad. You can check the new formats for Adsense ads.

For using the rounded corner, visit the ‘Adsense setup” tab. With all format options like sizes and colors, you will find three different corners in ‘Corner Styles’ heading.

Google in the official AdSense blog says that they’re “also working to give you even more choices to customize your ad formats.”
