The new iPad is about the same size as the iPad 2.
Here’s a simple comparison of all 3 versions of the iPad:
Not a huge difference.
The new iPad is thicker than the iPad 2, but only by .024″.
That’s like adding 13 sheets of printer paper to the iPad 2, or 9 human hairs (at about 70 µm each).
Will an iPad 2 case fit my new iPad?
It’s possible, but it depends on the case.
Because the difference in size is so small, iPad 2 cases will likely fit the iPad 3 – but it will be a tight fit.
You’ll probably want to get an actual new iPad case from ZAGG instead.
