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.
Another way to find an approximate weight is to measure around the horse as I've described, and take an additional measurement from the point of the horseâs shoulder to the âedgeâ of the haunch. With this measurement you can then do a bit of math: girth x girth x body length Ã· 300 = Horseâs weight. Yes, you multiply the measurement around the girth twice. You may also see this referred to as heartgirth. So if your horse is 76 inches around and 38 inches long you would calculate 76 x 76 x 38 Ã· 300 = 782 lbs. this method is the traditional formula for estimating weight, but other formulas do exist.
