If it just says ipad then it is for the first generation. The iPad2 is thinner so cases made for the iPad2 don't fit original iPads. But i don't know if cases made for the ipad fit the ipad2, my guess is yes but poorly.
im sorry i cant be more of help but i brought it for my tablet with out looking at the size it was too small i have a 10inch both of them have never been used so they are not out of shape it just might fit
