I am a pooh sized woman and had no problems. If you can fit into an airline seat you will be fine and then some since the belt extends very far out. Also my fil, cousin and aunt are all very large people who are also tall and they had no problems. I have ridden this ride too many times to count at both DCA and Epcot and have never seen anybody not fit just fine. Ride and enjoy it! I would say the seats are more generous than say TOT which has somewhat similar seats.
