Every
body is different, so take this FWIW. I'm 6'2" and have been to Universal from 220 to 285. My weight gains evenly distributed from top to bottom..
220 - All good.
230 - RRR becomes difficult to breathe because bar squeezes my diaphragm the way it closes from the side. But still ride it, just only take breaths when body is being forced back against the seat.
235 - RRR out.
245 - Dudley starts getting difficult to get out. Can straighten my legs and gravity drops me right in and plenty of room to sit, but can't bend legs much so "inch worming" to push my butt up the seat back is tough getting out
260 - Dudley out.
FJ and Hulk gets tight on chest but doable.
285 - Hulk extremely tight. Doable, but not worth it - out.
FJ pretty tight but doable
Mummy extremely uncomfortable but my favorite ride, so I do it .. but only because I'm done having children. The padded shark fin on the seat between your legs gets driven right into the jewels. 4th row may account for larger upper bodies but doesn't seem to address larger butts (at least not front to back).
Cat in the Hat is tough to get knee room in either the front or back row (forget which). Doable, but need to spread legs quite a bit if you are in the wrong row. Only big problem if sharing seat with another adult.
*From about 250 on up, Jurassic Park River Adventure actually gets better the bigger you get. Your comfort level doesn't change, but you get to watch the thrills get exponentially better for any kids in your row as the chest bar becomes more and more worthless for them.
