To measure girth correctly, the tape (weight tape or conventional measuring tape) should be snugly positioned around the horse’s barrel, directly behind the elbow and passing over the back at the lowest part of the withers.

To measure length correctly, place one end of the measuring tape on the point of the shoulder, keep the tape taut and run it diagonally to the point of the buttock. Stand by the horse’s back leg and read the tape without peering around the horse’s body.
