I have the 24" high one. I think it depends on if you are leaving the puppy in there when you are gone. If so I would recommend no shorter then 24", just to be safe.

Mine is 30". I have two - one for each puppy. My dogs will be 8 months old next week and they have never shown any interest in trying to jump out. I love mine because it has the waterproof canvas bottom. Here is a link for the mat, but shows what the whole setup looks like.
