We jump about 90-95cm at home. He's horse trailing at 75cm (until he gets his Cross Country act together).
Whenever we have been to jumping clinics, he's often ended up jumping 100cm - 105cm.
The highest I know we've jumped is 108cm. But I can't tell you what we've jumped in the way in cross country fences. There's a local-ish reserve with a cross country course that goes up to two star. I may have, I'm not certain, jumped a couple one star fences, which I think are about 110cm.
We've jumped about 130cm wide. But mostly school over 100cm wide.
