There are charts online that tell you what size to get based on your height. I am 5'7" and have a 25 inch ball, which seems right for exercises where I am siting on it. However, that seems too big to use with the "dead bug" exercise, so I am going to get a smaller ball for that. So it depends how you plan to use it.
