Abstract: A golf tee gauge has a hollow cylindrical form with a first end and an opposite second end. The first end receives the head of a golf tee. Away from the first end and towards the second end, the gauge has a stiffener that spans the internal diameter gauge. The stiffener has a thickness along the length of the gauge that resists impact and axial forces applied to the head of a golf tee. The cylindrical form of the gauge has a wall with its own thickness. In alternate embodiments, the gauge has a plurality of scribes that allow a golfer to select the embedment distance of a tee when used with the gauge. The scribes permit a golfer to cut, or to manually snap off, portions of the gauge, matching the desired height of the tee above the ground for customizing a golfer's tee height.
