I've always heard that theatres change from time to time. If a show is a hit, they'll scoot the rows closer together and add more in.
I don't know if that's true or not, but it would make it harder to figure out the safe bets. You'd have to find a list somewhere (if there is such a thing), and it would also have to be current, based on the show that was playing there now.
I remember the New Amsterdam for "Lion King" was a bitch. I needed a shoe horn to get in and out of my seat. There was only enough knee room for a 5-year-old child.
You can always tell a hit show by how crammed-in the seats are. (Or at least, that used to be a saying.)
