Golf Simulators 101: How Much Space Do You Really Need?
Learn the basic height, width, and depth requirements for a home golf simulator — plus the best options if your garage, basement, or spare room is tight on space.
How much space do you need for a golf simulator?
The most common baseline recommendation is something like this:
10-foot ceilings, 10 feet of width, and roughly 12 to 16 feet of depth.
If you have that, great. You’re in pretty solid shape.
But if you don’t have that, you are not necessarily doomed.
Most people are not building in a giant empty room with perfect ceilings and no obstacles. They’re trying to make something work in a garage, basement, or spare room that has beams, lights, shelves, garage rails, or dimensions that are not perfect.
And in a lot of cases, that can still work.
The key is understanding what the dimensions actually matter for, and then being realistic about the type of setup your space can support.
TL;DR
Height: 10 ft
Width: 10 ft
Depth: 12-16 ft
But if your space is tight - you still can make something work. A photometric launch monitor, compact net, hitting mat, and a monitor display will be your best combination.
The basic space recommendations
If you want the quick version, here it is:
Height: around 10 feet
Width: around 10 feet
Depth: around 12 to 16 feet
That is a very reasonable starting point for a home golf simulator. Now, are those numbers universal? No.
A lof of people get away with a lot less. Some setups need a little more. Some rooms look good on paper but are awkward in real life because of soffits, garage tracks, or wall placement.
But as a broad recommendation, those numbers are directionally correct.
If your room is around there, you probably have a real shot.
If your room is under those numbers, you may still have options. You just need to understand the tradeoffs.
Why each dimension matters
This is the part that matters more than the raw numbers.
Because a room is not “good” or “bad” just based on dimensions alone. What matters is why those dimensions matter in the first place.
Height: so you can swing comfortably
This is usually the most obvious one.
If the ceiling is too low, you are going to know it immediately.
Height matters because you need to be able to swing comfortably without worrying about clipping:
the ceiling
a beam
a garage door opener
garage rails
a light fixture
ductwork
a fan
And this is not just about whether your club technically misses the ceiling by half an inch.
You want to be able to comfortably make a real swing without any thoughts of the ceiling coming into a space thats already crowded with swing thoughts.
If you are guiding the club down, changing your motion, or feeling tense because you think you might hit something, that room is probably not going to be a good simulator space.
The goal is to be able to complete your fully normal swing - hundreds of times.
That is why height is such a big one. However, because golfers come in different heights and have a massive variety in their swing, its difficult to know for sure what is the minimum height that will work for you.
Width: for comfortable swinging, mishits, and mixed-handed golfers
A room can technically be “wide enough,” but still feel awful if you are standing too close to a wall or feel boxed in during the backswing or follow-through.
Width matters for a few reasons:
being able to stand and swing comfortably
having some margin for mishit ball flights
allowing both righties and lefties to use the space
That last one is a big deal.
If you are the only one using the sim and you are fine designing it for just you to use it, you can sometimes get away with less width. But if you want both right-handed and left-handed golfers to hit in the same space, width becomes much more important.
And mishits matter too. For most of us, not every shot is going to go dead straight into the center of the screen or net. If the space is extremely narrow, that can create safety issues or at least make the whole thing feel a little sketchy.
Depth: for launch monitor requirements and ball flight
Depth is where the components of the setup really start to matter.
Depth matters because you need enough room for:
the net or screen
the hitting area
the golfer
the launch monitor setup
enough ball flight to get useful data (depending on the launch monitor you’re using)
Different launch monitors have different requirements, and different sim builds use space differently. Some setups need more room behind the ball. Some need more in front. Some are much more flexible for tight spaces.
That is why a short room does not always kill the project, but it may absolutely change the type of setup that makes sense.
If you have plenty of depth, great. You have more flexibility.
If you do not, that usually means you’ll need to be more intentional about the equipment you choose.
Where to start if your space is not ideal
If your room does not hit all the “recommended” numbers, here is the good news:
You may still be able to make it work.
And honestly, the best first test is not complicated at all.
Go to the space -> Take a golf club (ideally a long iron or driver) -> Try to swing.
That’s it.
Seriously.
If you want to know whether you have any chance of making a simulator work, go stand where the hitting area would probably be and make some swings.
Not a weak little half swing.
Not a little rehearsal.
A real swing.
If you can do that comfortably, you probably have a shot at building some kind of setup there.
If you cannot, no amount of optimism or product shopping is going to fix that. But maybe you should think about a different route - a temporary setup that you can put up and take down as needed. A setup like this in the garage is the answer for a lot of people.
The recipe for a tight-space golf simulator
If you do not have much room, here is the general formula that works best:
Photometric launch monitor
Compact net (or portable net)
4- or 5-foot hitting mat
iPad, iPhone, or PC
TV or monitor off to the side
1. Photometric launch monitor
Photometric launch monitors sit on the side of the hitting area, and use cameras to capture what happens at impact, and then use that to calculate the ball flight – radar based launch monitors, on the other hand, sit behind the hitting area and gather data from the ball flight; they require a certain amount of space between the unit and the ball, as well as a long enough ball fight (before it hits the net) to gather adequate data. For a lot of radar units, this is 16 feet or more. Photometric launch monitors remove the depth issue almost completely.
2. Compact net or portable net
In a small room, a full impact screen and projector setup is often simply not worth it. The screen will be cramped, and getting a good image projected is too difficult.
That does not mean you cannot have a good simulator. It just means a compact net (or portable net) may be the smarter choice.
A net setup is:
easier to fit
easier to move
usually (a lot) cheaper
more forgiving in awkward rooms
It may not look as flashy as a big dedicated screen, but if the alternative is trying to shoehorn a full build into a bad fit, the compact net is often the better move.
3. A 4-foot or 5-foot hitting mat
If space is tight, a giant mat usually is not helping you.
A 4-foot or 5-foot hitting mat is often plenty for a compact build. It gives you enough room to stand and hit without eating up unnecessary floor space.
This is another place where being realistic matters. In a limited room, every foot counts. You want the setup to feel usable, not crowded with oversized components.
4. iPad, iPhone, or PC
In a smaller setup, your processing solution can be simple.
You do not need to overcomplicate this.
An iPad, iPhone, or PC can absolutely be enough depending on the launch monitor and software you are using. If the room is limited, this is not the place where you need to build out some giant elaborate tech station.
Keep it clean. Keep it simple. Keep it functional.
5. TV or monitor
This is one of the easiest ways to make a small-space sim more doable.
If you do not have the room for a full projector-and-screen build, just put a TV or monitor off to the side.
That setup can still work really well.
You are still getting:
simulator data
ball flight feedback
course play
practice functionality
No, it is not the same as blasting the image onto a full impact screen in front of you. But in a tight room, it is often the smart compromise.
And honestly, a compact setup that is easy to use beats an “immersive” setup that barely fits and becomes annoying every time you want to hit balls.
Final thoughts
So, how much space do you really need for a golf simulator?
A good baseline is:
10-foot ceilings
10 feet of width
12 to 16 feet of depth
That is a great starting point.
But if you do not have that, you are not necessarily doomed.
Height matters because you need to swing comfortably.
Width matters because you need room to swing, room for mishits, and ideally room for both righties and lefties.
Depth matters because of launch monitor requirements and ball flight.
And if your space is tight, the best path is usually a simpler setup:
a photometric launch monitor, a compact net, a smaller mat, and a side TV or monitor.
That may not be the dream simulator room you see on Instagram.
But it can absolutely be a really useful, fun, and smart home golf setup.
The first step is simple:
go to the room, grab a club, and take a swing.
That will tell you a lot more than a spec sheet ever will.
