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.
A hand (or handbreadth) is a unit of length measurement, usually based on the breadth of a male human hand and thus around 4 inches long (about 10 cm). When used to measure height, it is abbreviated h (for hands) or hh (standing for hands high) Today it is primarily used to describe the height of horses, ponies, and other equines in a number of different countries, including the USA, Australia, and the UK. In this context, one hand equals four inches (10.16 cm), and the horse is measured from the ground to the top of the withers. So a horse that is 15 hands high (abbreviated 15 hh) is 60 inches (152 cm) from the ground to the top of the withers.
