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.
It is a common unit of measurement now used only for quantifying the height of the horse. Tracing a tradition backward is a dicey proposition. We know that today a hand is 4 inches, with one inch increments, and the measurement is from level ground to the highest non-variable skeletal structure on the horse, the withers.
