A DIY golf simulator is five parts you choose yourself: a launch monitor, a hitting mat, an impact screen (or net) in a frame, a projector or TV, and software. Build it in this order: measure the room, pick the launch monitor that fits it, then the frame and screen, then the projector, then the software. Doing it in that order avoids the two expensive mistakes, a launch monitor that needs more depth than you have and a projector that can't fill your screen from where it hangs.
Here is the full build, step by step.
What you need for a DIY golf simulator
| Part | What to look for | Where to read more |
|---|---|---|
| Launch monitor | Fits your room depth; works with the software you want | Room size guide |
| Hitting mat | Takes a real tee, absorbs shock, at least a hitting strip plus stance area | Best hitting mats |
| Impact screen + frame | Rated for real balls, quiet, sized to your projector's aspect ratio | Impact screens and enclosures |
| Projector | Short throw, bright, matched to screen size and mounting spot | Best projectors |
| Software + computer | Runs on your launch monitor; PC only if your software needs it | Simulator software |
| Safety extras | Side netting, ceiling baffle, floor padding at the base of the screen | This guide |
How to build a golf simulator in 8 steps
1. Measure the room (and swing in it)
Measure ceiling height, width and depth wall to wall. Then stand where the ball will be and make a slow practice swing with your driver, as SkyTrak suggests in its room advice. If you flinch at the top, you need more height or a different spot.
As a starting point from makers' guides: a 9-foot ceiling is the practical minimum for a driver, 10 feet is comfortable; 10 to 12 feet of width; and depth depends on the launch monitor (step 2). Run the numbers through our golf simulator room size calculator before you buy anything.
2. Choose the launch monitor for your depth
This decision sets everything else.
- Short rooms (about 10 to 15 feet deep): a camera unit that sits beside the ball, such as a SkyTrak, Square Golf, Uneekor EYE MINI or Bushnell Launch Pro.
- Deeper rooms (14 to 16 feet or more): radar units that sit behind you also work, such as the Garmin R10 (6 to 8 feet behind the tee plus 8 feet to the net, per Garmin) or the FlightScope Mevo Gen2 (8 feet plus 8 feet, per FlightScope).
Check that the unit works with the software you want. GSPro, for example, publishes a list of officially supported launch monitors.
3. Plan the layout on the floor
Tape it out before you build:
- Mark the screen line, leaving a gap behind the screen so the ball's impact doesn't reach the wall (follow your screen maker's guidance).
- Mark the ball spot at least as far from the screen as your launch monitor's manual asks: at least 8 feet for the Garmin R10, about 10 feet for the Voice Caddie SC4 Pro.
- Mark where the launch monitor sits (beside the ball or behind it).
- If left- and right-handed players will share the bay, center the hitting area or plan two mat positions, and add 1 to 2 feet of width, per SkyTrak.
4. Build or assemble the frame
You have two routes:
- Full DIY frame: steel EMT conduit or pipe cut to length and joined with corner connectors is the common approach. Anchor it so it can't tip, and keep the screen tensioned evenly.
- DIY kit: a kit gives you a pre-sized frame and screen to assemble yourself. Carl's Place, for example, sells a 4:3 enclosure kit with a Preferred impact screen in a low-profile 5-foot-deep frame on Amazon.
5. Hang the impact screen and add protection
Attach the screen to the frame with bungees or ball bungees through the grommets so it can flex on impact. A tight, flat screen gives a cleaner image; too tight and balls bounce back harder. Then add:
- Side netting or curtains to catch shanks and thin shots.
- A ceiling baffle or top net if your ceiling is close.
- Foam padding at the base of the screen where low shots land.
For screen types, sizes and kits, see our golf impact screen guide.
6. Lay the mat and turf
Put the hitting mat where you taped the ball spot, then fill the rest of the floor with turf so you're not swinging on concrete or carpet. Choose a mat that takes a real tee and has a forgiving surface; a cheap mat is the fastest way to sore wrists. Our best golf hitting mats guide compares options for simulators.
7. Mount the projector
Short-throw projectors let you mount closer to the screen and keep your shadow off the image. The math is simple:
Throw distance = throw ratio x image width.
With a 0.5 throw ratio and a 10-foot-wide image, the projector sits about 5 feet from the screen. BenQ's AH500ST, for example, lists a 0.499 throw ratio. Ceiling-mount it above and slightly in front of the hitting area, or use a floor box in front of the mat. Match the projector's aspect ratio to the screen (4:3, 16:10 or 16:9). Our best projectors for golf simulators guide explains brightness, aspect ratio and placement.
8. Connect the software and calibrate
Install your launch monitor's app or simulator software, connect it (Wi-Fi, Bluetooth or Ethernet, depending on the unit), and run the maker's alignment routine. Then hit a dozen shots with one club and check that the start line and carry look right. Software choices and their computer requirements are covered in our golf simulator software guide.
Finishing touches: light, sound and comfort
A few small additions make a DIY bay much nicer to use:
- Blackout: cover windows or glass door panels so the projector doesn't fight daylight.
- Hitting light: a dimmable light over the hitting area helps camera units and your own setup, without washing out the screen. Check your launch monitor's lighting advice.
- Sound: multi-layer screens are quieter, and a rug or turf over a hard floor cuts echo.
- Ball tray and alignment: a tray keeps balls handy, and a tape line on the turf keeps your stance square to the screen.
- Ventilation: projectors and PCs make heat; a small fan keeps the room comfortable in summer.
DIY vs a complete package
| DIY build | Complete package | |
|---|---|---|
| Cost | Usually lower; spread over time | Higher, one purchase |
| Planning | You size and match every part | Parts matched for you |
| Flexibility | Choose a better mat, screen or projector | Limited to the bundle |
| Time | More build time | Faster assembly |

Common DIY golf simulator mistakes
- Buying the launch monitor before measuring. A radar unit needs 6 to 9 feet behind the tee; many garages don't have it.
- Mounting the projector before choosing the screen. Throw ratio and screen size must match.
- No side protection. Shanks happen. Netting is cheap; drywall repairs aren't.
- A thin mat on concrete. It's hard on joints and makes contact feel better than it is.
- Screen flush to the wall. Leave the gap your screen maker recommends.
- Ignoring light. Windows and overhead lights wash out the image; plan blackout curtains or a brighter projector.
FAQ
Is it cheaper to build your own golf simulator?
Usually, yes. A DIY build lets you buy the enclosure, screen, mat and projector separately, reuse a PC you own and spread the cost over time. Complete packages save planning time and guarantee the parts fit, so the gap shrinks if you value that.
What do you need to build a DIY golf simulator?
A launch monitor, a hitting mat, an impact screen or net (ideally inside a frame or enclosure with side protection), a projector or TV, and software running on a tablet or PC. Add padding, a ceiling baffle and good lighting control.
How do you build a DIY golf simulator enclosure?
Most DIY enclosures use a frame of steel conduit or pipe joined with corner connectors, an impact screen attached with bungees through its grommets, and side netting or curtains to catch mishits. A DIY kit, like Carl's 5-foot-deep enclosure kits, gives you a tested frame and screen to assemble yourself.
What size room do you need for a DIY golf simulator?
Launch monitor makers point to roughly a 9-foot ceiling minimum for a driver, 10 to 12 feet of width, and about 10 feet of depth for side-of-ball camera units with a net or 14 to 16 feet for radar units that sit behind the ball.
Can I use a TV instead of a projector?
Yes. Many DIY builds start with a net and a TV or tablet beside it. A projector and impact screen give the big, immersive picture, but they're an upgrade you can add later without replacing the launch monitor.
