There are numerous testing tools that you can use to see if your content will display correctly on iPad. My favorite is Responsinator which not only show how your website will display in Ipad but it will show how it will display for other idevices like iPod and iPhone. It also shows display on android tablets. The key to getting your site displayed right on all mobile devices is to make all aspects of your site Responsive. Techlivewire is responsive and displays well with nearly every mobile device. Having a Responsive device will also help boost your rankings for search results that are displayed to mobile devices.
