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 horse is measured from the ground to the withers (the tip of its shoulders), in units called hands (one hand equals 10.2 cm or 4 in.). Adult male Clydesdales measure 17 to 19 hands (1.7-1.9 m or 5.7-6.3 ft.). A male's average weight is between 771 to 998 kg (1,700-2,200 lb.).
