A horse is measured in hands from its withers to its hoof. The withers is at the base of the neck. :]
it really depends on the type of horse, so if you really want to know, i suggest you learn the breed of the horse and look the breed up. most regular sized horses get to be around 14.2 hands. Hands is what a horse is mesured with, i suggest you look that up too.
