TREE SIZES
Semi-QH: Semi Quarter Horse can be referred to as Medium, Regular, or QH bars. This tree size has a higher pitch or angle to the bars. It’s for the horse with a more defined wither. (1/2 Arab, Appendix, Thoroughbred, etc).
Full-QH: Full Quarter Horse or FQHB can be referred to as Wide (usually 7” gullet). The angle is flatter compared to the Semi-QH tree. This is for horses with a broad shoulder. They’re considered mutton withered or a less pronounced wither. (Quarter Horse, Paint, etc)
Arabian: Have a narrow front (usually 6.5" – 6.75" gullet) similar to the Semi-QH bar but the back of the saddle has a flatter pitch angle. So the saddle goes from a little narrow in the front to flatter or wider in the back. Can sometimes fit non-Arabian horses.
Gaited: The gaited tree has a higher gullet to accommodate the higher withered horses. They usually have a wider or flared front to allow for shoulder movement. The tree narrows toward the back where the bars have more pitch. The gaited saddles usually have more rock to the bars. (Tennessee Walker, Fox Trotter, etc)
Haflinger: Short backed, mutton withered – these trees have a flatter pitch to the bar angle and very little rock. Usually a 7.5" gullet, they’re often used on other large horses needing an extra wide tree.
Draft: Usually an 8" gullet to fit on large draft horses.
