Check whether a golf simulator fits your room
Start with the ceiling. If it's too low, no amount of money gets you a driver swing. Depth comes next, because it decides your launch monitor. Then width. Change any number and the answer updates.
Measure at the lowest point above where the mat will go. That means under lights, ducts, beams and the garage door track. Write the numbers down before you start.

How the checker decides
The ceiling figure starts at 9 ft. That's for a golfer up to 5 ft 10 in, swinging a driver on a neutral plane (not too flat, not too upright). For every 2 in you're taller, it adds 3 in. Irons only? It takes off 9 in. A flat or upright swing moves it 3 to 6 in either way.
If you're within 6 in of the figure, the chip still says Fits. But the note tells you to make a slow practice swing first.
The depth figure is worked out for each launch monitor. It uses the maker's own advice on where the unit sits, from our launch monitor guides. It adds three things. First, how far behind the ball a radar unit has to sit. Then the 8 ft of ball flight most units ask for. Last, 1 ft of gap behind an impact screen so the ball never hits the wall. A net needs no gap.
A camera unit sits beside the ball, so it only needs about 4 ft of swing room behind you. That's why it fits a 12 ft room with a net, or 13 ft with a screen, where no radar can. Our space guide walks through the same numbers with diagrams.
Width is simpler. You need 10 ft for one golfer and a net. Make it 12 ft if a righty and a lefty will both hit from the center. An enclosure with side netting feels tight until about 15 ft. Want to see what goes where? The dimensions guide has four sample room plans.
When the answer is no
A ceiling a few inches short usually means irons and hybrids, not no simulator at all.
Room a foot too shallow? Try a net instead of a screen. A net needs no gap behind it, and a screen needs a foot. In a garage with a low door track, you may find 10 ft of ceiling two feet further in.
And if nothing works, there's still an option. A system with no real ball flight, like the OptiShot, is in our budget simulator list for exactly that room.

Questions people ask
What ceiling height do you need for a golf simulator?
For most golfers swinging a driver, 9 ft is the practical minimum and 10 ft is comfortable. If you’re tall or swing upright, aim for 10 ft or more. Under 8 ft 6 in, plan on irons and hybrids, or a flatter swing.
How much height do you need for a golf simulator if you only hit irons?
About 8 ft 6 in works for most golfers with mid and short irons. Pick irons only and the checker takes 9 in off the driver figure. Then it adds some back if you’re tall.
How tall a ceiling does a golf simulator need in a garage?
The same 9 to 10 ft as any room, measured at the lowest point over the mat. In a garage, that low point is usually the door track or the opener, not the ceiling. So measure under those.
How deep does a room need to be for a golf simulator?
A radar unit sits behind you and tracks the ball as it flies. It needs 7 to 8 ft behind the ball, plus 8 ft of ball flight. An impact screen adds another foot. That’s 15 to 16 ft with a net, or 16 to 17 ft with a screen. A camera unit sits beside the ball, so it fits in 12 ft with a net and 13 with a screen.
