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.
Horse height is correctly referred to by a unit of measurement known as a hand.. One hand is equal to four inches. The gray mare in the photo above is 58 inches from the ground to the top of her withers. When 58 is divided by 4, you have 14.5. The 14 is the number of hands, and the .5 means another half of a hand, or another 2 inches.
