In this method, it is critical that the lie of the club be positioned correctly. If the club is placed with the toe raised higher off of the ground than the heel, then the measurement will be less than that measured with the center of the sole touching the ground. Conversely, if the heel is raised higher off the ground than the toe, then the measured length will be higher. If not careful in positioning the club correctly you can easily be off +/- 1/8” or more.
