Ask HN: How to get Ads fit the Content?

I use Google AdSense to display ads on my web-app (dezidr.com). Unfortunately, the ads don't really fit the contents. Take this as an example: http://dezidr.com/en/home/show_option/295.

Do you know how to get better ads? Is there a way to optimize AdSense? Are there ad-services with better targeting? Thanks for any idea!
