The Better Golf Tee sizes

We measure differently. Our spec is the ball-bottom height above the mat surface, not the tee length. The tee itself is shorter than the ball-bottom number suggests, because our cup design seats the ball ON the cup lip (not deep into a wooden tee's cup well).

Better Golf Tee SKUBall-bottom heightEquivalent wooden tee length
Driver1¾" (44.5 mm)~2⅛" wooden tee at standard depth
Mini driver / 3-wood1" (25.4 mm)~1⅜" wooden tee at standard depth
2-iron / utility / Par 3¼" (6.4 mm)~½" wooden "castle" tee

Conversion notes

1 inch = 25.4 mm exactly. Most tee manufacturers spec in inches in the US and millimeters in Europe / Asia. The 4-inch USGA maximum is 101.6 mm.
