When planning your Walt Disney World vacation, there is lots to think about. From ticket types to where to stay, you’ve got to be prepped and ready to maximize the magic.

But one thing that you may not have thought about — but should absolutely know going in — is your kids’ heights! While most Disney attractions and shows are fit for the whole family, the thrill rides have specific height requirements.
We’ve compiled all of them, by height, along with alternate attractions nearby for little ones who don’t make the cut (or grown ups who don’t want the thrill). The alternate attractions are good ones, but maybe not things you’ll want to save for the entire family. This way, you can hopefully avoid any tears when the little kids can’t ride the same things as the big kids.
