Driver tee height: why 1¾".
Half the ball above the crown of a modern 460cc driver lands at 1¾ inches ball-bottom. Here is the physics.
The classic rule
"Half the ball above the crown." Every instruction book repeats it. It is correct, but only if you account for what the crown of a 460cc driver is actually doing in 2026: about 58mm above the sole at address for most heads.
Doing the math
A USGA-conforming golf ball is 1.68 inches (42.67mm) in diameter, so the ball radius is 21.33mm. If the equator of the ball sits at the crown (58mm), the ball bottom sits at 58 - 21.33 = 36.67mm above the sole. But the sole sits roughly 8mm above the ground at address. So ball-bottom-above-ground = 36.67 + 8 ≈ 44.7mm, which rounds to 1¾".
Why this matters for simulator practice
If your simulator tee gives you a ball-bottom of, say, 1¼", you are teeing the driver effectively a half-inch lower than you would on grass. Your launch angle drops by roughly 2°, your spin rises, and you build a swing path that does not work outside.
Why 1¾" specifically
1¾" is the sweet spot for a 460cc driver hit on the upper-center of the face, which is what most modern drivers want. Players who prefer to "tee it higher and rip" sometimes go 2", and we will offer that as a refill upgrade.
Common questions
What if I have a 440cc or smaller driver?
Drop to 1½ inches. The smaller crown sits lower at address.
Can I order a custom 2" driver tee?
Yes, as a refill pack. The 4-pack ships with 1¾ standard.
