How to Measure. To measure your horse, have him stand square on a level surface. Hold the tape or stick so it is perpendicular to the ground and beside the horse so it is even with the top point of the horseâs withers. If you are using a proper measuring stick, lower the bar so it meets the top of the horseâs withers.
Horses are measured from the shoulders, where the back and neck meet, down to the ground. The average Draft Horse is about 18 hands high or 18 hh. This is multiplied by 4 inches to equal 72 inches, or 6 feet tall from hoof to withers. The average height of a Clydesdale ranges from 16 to 18 hh, while Belgian horses are around 16 hh. Most riding-horse breeds, including thoroughbreds, have an average height of 16 hh. Learn more about Barnyard Mammals.
