How high does a ceiling have to be for a golf simulator? Height, width and depth in numbers
The question before any home simulator is the room, not the device. Three measurements, a test that takes a minute, and the honest answer for a garage with 2.4 metres.

The question that comes before any home simulator is not which device, but which room. And it has a number: 3.0 metres of ceiling height. That is what TrackMan names as the practical minimum for a full swing, together with 4.6 metres of width (TrackMan, space requirements). A Swiss garage is usually 2.4 metres. That alone is why most plans end in the cellar before they ever reach a price.
The three measurements, by system
Height and width are the same for everyone, depth is not: it depends on where the measuring unit sits.
| Measurement | Ceiling unit | Radar behind the ball |
|---|---|---|
| Ceiling height | 3.0 m and more | 3.0 m and more |
| Room width | 4.6 m and more | 4.6 m and more |
| Depth | 3.0 m from ball to screen | 5.5 m from unit to screen |
The figures are TrackMan's, for the iO, the ceiling unit, and for the TrackMan 4, the radar that stands behind the ball. The two and a half metres of difference in depth are not a detail: they decide whether a room is a candidate at all. Camera systems that stand beside the ball sit in between, at roughly 3.7 to 4.6 metres of depth (Best Golf Simulator).
The test that takes a minute
Before you compare a single device, take the longest club you play and stand in the room.
- Address a ball where the mat is going to be.
- Make the backswing in slow motion all the way to the top. If the club touches the ceiling, a lamp or a beam, the room is too low.
- Repeat it with the follow-through. For many players it goes higher than the backswing, and that is where the club hits something.
- Measure at the lowest point of the room, not in the middle. A beam, a lamp or a sprinkler head decides the question, not the average.
If nothing gets in the way, the room fits your swing. That is no guarantee for every guest: a taller person with a flatter swing needs more height than you do. Anyone who opens the bay to others works with the 3.0 metres rather than with their own head.
Why depth depends on the system
A radar measures the ball in flight. Indoors it only has the distance to the screen for that, and the shorter it is, the less it sees. That is why TrackMan asks for 5.5 metres between the TrackMan 4 and the screen: the unit stands behind you, you stand in front of it, and the ball needs distance after that.
A ceiling unit or a camera system measures impact itself, not the flight. For it, the 3.0 metres between ball and screen are enough, so the ball does not rebound and the projector is out of the way. In a room five metres deep the choice is therefore made before price matters at all. What else separates the two designs is in Radar or camera.
Left- and right-handers in the same room
The 4.6 metres of width are not comfort, they are two hitting positions. A right-hander stands right of centre, a left-hander left, and both need room for the club's whole arc. Building for yourself alone needs less, but the room is then fixed to one side, and the mat does not sit centred in front of the screen.
A commercial venue adds both: width for both sides and distance so somebody can watch without standing in the swing arc. That is why a bay in a lounge feels bigger than any cellar with the same device hanging in it.
The mat costs you ceiling height
One measurement no maker lists: in the finished room you stand higher than you did when you measured. A hitting mat has thickness, and on a platform or a second layer it has more. Whatever the mat is high is missing above you, on every shot.
So: put down the mat you actually intend to buy, stand on it, and then do the driver test. The same goes for the floor underneath. An uneven cellar floor tilts the mat slightly, and a ball lying at an angle turns every shot into a slope you did not choose.
Screen, projector and the distance between them
The three measurements are about the swing. Two more are about the picture.
The distance to the screen. The 3.0 metres between ball and screen are not only measurement, they are safety: a ball striking a tensioned screen from one metre comes back faster than you react. The screen also needs air behind it so it can give; fixed flat against a wall, every ball rebounds and the wall takes the damage.
The projector. In a short room an ordinary projector will not throw a big enough picture, and a projector at swing height throws your shadow with it. A short-throw unit under the ceiling, behind the swing arc, solves both. Then there is daylight: a screen in sunlight loses contrast, and a window behind the projector is worse than none.
What a room that is too small really costs
Not accuracy. A camera system measures the same values in a low room as it does in a hall, because it reads impact. What a room that is too small costs is the swing.
Hitting with 2.4 metres above you shortens the backswing without you noticing, flattens it or stops it before the top. You practise that, every evening, and it is exactly the move that no longer fits on a course. So the honest answer for a low room is: wedges and short irons yes, driver no. A net for half swings and the short game then makes more sense than a simulator that makes you duck. What works there is in Practising golf at home.
The measurements of Swiss rooms
A usual garage is 2.4 metres, a cellar in an older building rarely more, and an attic has its slope exactly where the club comes up. What does fit are commercial units, barns and new-build cellars with high ceilings, and that is exactly where the country's 110 indoor venues are: in lounges, studios, hotels and gyms that had the room anyway.
That is the sober alternative to a room of your own. An hour in a bay is a median CHF 50 for up to four people, and the ceiling there is high enough for a driver. Which venue near you has how many bays is in the venue list; whether a simulator of your own adds up is in Buy or rent.
Between 2.4 and 3.0 metres
Most rooms sit exactly in between, and there are three honest answers for that. First: measure rather than estimate, because ten centimetres decide it. Second: a shorter shaft does not solve it, because the club does not come up in the backswing on account of its length but on account of your arms. Third: a room of 2.7 metres is an excellent room for irons, wedges and the short game, and that is the part that saves the most strokes on a course.
The driver you then hit where the ceiling was built for it. An hour in a bay costs less than the projector you would otherwise buy twice.
The checklist before you buy
- Height at the lowest point, including lamp, beam, pipe and sprinkler.
- Depth from the planned ball position to the wall, plus the room behind you for the swing and, if needed, for the radar.
- Width where the mat will lie, not at the room's widest point.
- Door and stairs: an enclosure arrives in parts, a three-metre screen does not go round every corner.
- Power and light: projector, computer and unit need sockets, and daylight on the screen costs contrast.
- Neighbours: a ball into a net is a bang the flat next door can hear.
Answer those six and you know your system before you compare a price. That is the order that saves money.
Frequently asked questions
How high does the ceiling have to be for a golf simulator?
TrackMan names 3.0 metres as the practical minimum for a comfortable full swing. Below that it gets tight: a usual Swiss garage is 2.4 metres. Measure at the room's lowest point, so including the lamp, the beam and the sprinkler.
How much depth does a golf simulator need?
That depends on the device. A ceiling unit like the TrackMan iO needs 3.0 metres between ball and screen, while a radar behind the ball such as the TrackMan 4 asks for 5.5 metres between unit and screen. Camera systems beside the ball sit at roughly 3.7 to 4.6 metres.
Is my garage big enough for a golf simulator?
Usually not for a full swing. The test takes a minute: backswing and follow-through with your longest club, in slow motion. If nothing touches the ceiling, the room will do. Otherwise wedges and short irons remain, and a net is enough for those.
How wide does the room have to be for left- and right-handers?
4.6 metres and more. Two hitting positions each need the club's full arc, and the mat should sit centred in front of the screen. Building for yourself alone needs less, but it fixes the room to one side.
Does a small room hurt measuring accuracy?
Not with a camera system, which reads impact and needs no flight. A radar has a harder time in a short room and derives spin from the club and the strike. The real loss in a low room is not the number but the shortened swing you teach yourself.
