A golf tee stopper having a center aperture of material and design so as to slide over a golf tee while creating enough friction with the tee to act as a stop against the ground when teeing a golf ball using the method as described herein and providing the capability to repeatedly insert a golf tee to essentially the same depth to thereby allow the golf tee to hold a golf ball at a height preferred by a user. A set of calibration indicia on the golf tee stopper can be used to mark a golf tee in a manner that assists in the repeatable placement of the golf tee at a substantially consistent height.
