A horse's hooves are as individual as people's feet. They are naturally shaped according to a horse's conformation and whatever kind of work the breed of horse was meant for. However, there are general angles and shapes that can be assumed to apply to most horses.
Front hooves slope at about a 50 degree angle, while rear hooves slope at about 60 degrees. The pastern angle should be about the same as the angle of the front of the hoof. The distance to the ground of the coronary band on the front of the hoof (measured straight down) is twice the distance of the coronary band to the ground at the back of the foot. The hoof wall is thicker at the toe than at the heel.
