horse box builder confirmed that they have had 17'1 in them it's around 8ft just measured it our stall is also bigger as we moved the partition to the right to travel just one so buddy has more room10ft sounds a lot! I'm pretty sure mine is 8 and Harvey is very comfortable in it (He is 17hh)
Yes you are right. I didn’t look carefully enough and just saw overall height. Apologies.I think 9 feet is from the ground to the roof? Everything I have found says 7'6" headroom
