The Short Answer
One weekend, $500-$8,500. LM, net/screen ($150-$600), mat ($100-$500), software. Frame with EMT conduit, mount projector, play Pebble Beach.
I know why you’re here.
You’ve seen the YouTube videos of finished garages with screens glowing at 2 AM. You’ve read the forum posts from guys who say “no regrets” and you believe them.
But there’s a thing between you and that screen. A gap. You don’t know how to close it.
You’re not asking “should I do this?” anymore. You’re past that. You’re asking “how.”
This is the how.

Why Build It Yourself?
Three hundred. That’s what you’d spend on a Carl’s Place enclosure kit if you bought the frame and screen separately and built it yourself. Eight hundred is what the pre-built version costs. That’s $500 to screw in some conduit fittings. You know how to do that.
Six weeks. That’s how long a pre-built package takes to ship if it’s backordered. Six hours is how long it takes to build the same thing out of EMT conduit from Home Depot. (Need a full walkthrough? Here’s how to build an enclosure from scratch →.)
Forever. That’s how long you’d wait for a contractor to quote you $2,500 to hang a screen and run an HDMI cable. Meanwhile, you could have done it in a weekend. With your hands. And then you’d know every inch of the setup, which means when something shifts in six months (it will), you’ll know exactly which screw to tighten.
One guy on the forums put it this way: “Building the enclosure was pretty miserable and my fingers bled quite a bit. But I’d do it again.”
You suffer a little. You save a ton. And your setup is yours — not a catalog clone.
Step 1: Plan Your Space (Before You Buy Anything)
Measure first. Buy second. I know you want to click the “Add to Cart” button. I know the excitement is real. But the #1 mistake in the forums — posted daily by guys who already learned the hard way — is buying a 9-foot screen and realizing their garage has a 7’6“ clearance because of a duct run nobody measured.
Don’t be that post.
Minimum Space Requirements
| Dimension | Minimum | Comfortable | Ideal |
|---|---|---|---|
| Ceiling height | 8’ | 9’–10’ | 10’+ |
| Depth (ball to screen) | 9’ | 10’–12’ | 12’–15’ |
| Width | 8’ | 10’ | 12’+ |
Real talk on these numbers:
Ceiling height is the one that kills builds. You at 6’ tall with a 48“ driver need at least 8’6“ of clearance. That’s not a suggestion. That’s geometry. Most standard 8’ garage ceilings work for irons but you’re crouching on a driver. The forum has a name for this: the “ceiling fan memorial shot.” Don’t hit one.
Depth matters differently depending on your launch monitor. Let me explain these terms now — a “camera-based” launch monitor (SkyTrak+, Bushnell Launch Pro, GC3) sits next to the ball and takes a photo at impact. It needs 5–7 feet in front of the ball to the screen. A “radar-based” unit (Mevo+, Rapsodo) bounces radio waves off the ball in flight. It needs 8 feet behind the ball. One wants room ahead. One wants room behind. Different math. Measure accordingly.
Width is easier. Minimum 8 feet gives you room for a 7-foot-wide screen with some buffer on each side. If you’ve got 10 feet, you’re in luxury territory.
Pick the Right Room
Ranked by actual forum results:
-
Garage — The people’s choice. High ceilings, concrete floor (handles ball drops), and you can close the door. Downside: temperature swings. One guy on r/GolfSimulator: “Played last night when it was zero degrees and the garage was 70.” Get a heater.
-
Basement — Best for year-round. Usually has the ceiling height if unfinished. Downside: you’re boxing with the furnace, water heater, and that one pipe you always hit your head on.
-
Spare bedroom — Works for a net-only setup. A full enclosure with projector? Probably not unless it’s a big room.
-
Backyard shed — Bold. We respect the hustle. But weather is the enemy, and condensation will kill your electronics.
Floor Plan Sketch
Before you buy anything, draw your room from above. Takes 10 minutes. Mark where you stand, where the ball goes, where the launch monitor sits, where the projector mounts, where the power outlets are, and any obstacles. This one sketch has saved more builds than any pro tip I can give you.
Step 2: Choose Your Components (and Your Budget Tier)
A golf simulator is five things. A launch monitor (the brain that tracks your ball). A hitting mat (what you stand on). An impact screen (what you hit into — it’s like a giant canvas that stops the ball and shows the picture). An enclosure (the frame that holds the screen). A projector (what shines the picture onto the screen). And software (what turns your ball data into a golf course).
That’s six things. I lied. But five of them are simple. The sixth — the launch monitor — is where all the money goes.
DIY Build Budget Tiers
| Component | Budget (~$800) | Mid (~$2,500) | Premium (~$6,000) |
|---|---|---|---|
| Launch monitor | Rapsodo MLM2Pro ($549) | Bushnell Launch Pro ($999) or SkyTrak+ ($2,095) | Foresight GC3 ($6,500) or used TrackMan |
| Hitting mat | Country Club Elite 5’x4’ ($130) | Fiberbuilt 5’x5’ ($400) | ProTeece / 6’x10’ premium mat ($700+) |
| Enclosure + screen | DIY EMT frame + Carl’s Place 8’ screen ($250) | Carl’s Place DIY enclosure kit ($550) | Custom PVC/wood enclosure + premium screen ($900+) |
| Projector | Used 1080p short throw ($150) | BenQ TH67 1080p short throw ($800) | Optoma 4K UHD50 short throw ($1,500+) |
| Software | Rapsodo app (free) | Basic E6 Connect license ($250/yr) | GSPro + full course library ($400+/yr) |
| PC/laptop | Your phone or iPad | Gaming laptop (GTX 1660+) ($900) | Dedicated mini PC + 32“ side monitor ($1,200+) |
A few notes. These prices reflect late-2025/early-2026 data. They assume you shop sales and the used market. The budget tier assumes you already own a phone or tablet — because you do. The premium tier gets close to “just buy a package” territory. DIY still wins on customization. The money savings at that level? Not as much.
The One Component You Should Not Skimp On
The launch monitor.
Everything else is decoration. A $200 enclosure and a $150 projector with a free app will still give you a great experience if your launch monitor is accurate. A $1,500 enclosure with a $99 launch monitor that misreads your spin axis will make you want to sell the whole thing and take up bowling.
The forums say this in a hundred different ways. Here’s the simplest: “Within 2 percent of Trackman” is the benchmark guys cite for a good launch monitor. Your launch monitor should be within 2% of a $20,000 Trackman. Everything else? Within 100% of what you can afford.
Step 3: Build the Enclosure
The enclosure is the frame that holds your impact screen tight and keeps golf balls from bouncing off your garage wall and hitting your car. You can pay $800 for a pre-built one. Or you can build one for $150–$300 that’s 90% as good. Let’s build one.
Tools & Materials Shopping List
One Home Depot run. One trip. Here’s the list:
For the enclosure:
- 1“ EMT conduit (10’ sticks — 6–8 sticks depending on frame size)
- EMT corner connectors / “tee” fittings (8 corners for a 3-sided box)
- Conduit clamps and 1/4“ lag screws
- Impact screen (Carl’s Place or Gawronski — $150–$400)
- Blackout cloth backdrop (behind the screen, $30–$60)
- Bungee cords or ball bungees (1–2 packs of 50+)
- Side netting or padding (optional, recommended for peace of mind)
For the projector mount:
- Universal projector ceiling mount ($25–$40)
- 2x4 stud or unistrut (if your ceiling joist isn’t where you need it)
- 25’ HDMI cable ($15)
- 15’ extension cord + surge protector
For the mat:
- Hitting mat (from your tier choice above)
- 1/2“ rubber stall mats underneath — 4’x6’ from Tractor Supply, ~$55 each (get 1–2)
- Double-sided carpet tape or Velcro strips
General build:
- Drill with bits (phillips, 1/4“, 5/16“)
- Tape measure (25’)
- Level (2’ or laser)
- Pipe wrench or Channellocks
- Utility knife
- Work gloves (EMT edges are sharp. Not a suggestion.)
- Step ladder
- Safety glasses (seriously — balls come back)
If you own a drill and a tape measure, you’re $120 away from having everything else from Harbor Freight.
Building the Frame
EMT conduit is Electrical Metallic Tubing — it’s the silver metal pipe you see in commercial ceilings. It’s cheap, rigid, and available at any hardware store. People try to use PVC because it’s cheaper. PVC flexes. A 100mph driver hit on a PVC frame bows inward, the ball pockets, and eventually the pipe cracks. Use EMT.
-
Cut your EMT to length. You’re building a three-sided box: top, two sides, and the screen plane (the back). For a 9’ wide x 7’ tall x 18“ deep enclosure: two 9’ top/bottom rails, two 7’ side rails, two 9’ depth rails, and four 18“ depth cross-pieces. Cut with a hacksaw or $12 EMT cutter. Deburr the ends or you’ll shred your screen.
-
Assemble dry first. Use the corner connectors. Lay the whole thing on the floor. Make sure it’s square. This catches wrong cuts before you’ve screwed anything to your wall.
-
Mark your wall mounts. Hold the frame against the wall at the right height. Mark through the conduit clamps where the lag screws go. Find the studs — you must hit studs. Drywall anchors will not hold a screen getting hit by golf balls.
-
Lag the frame to the wall. Two lags per side minimum. Pre-drill with a 3/16“ bit so you don’t split the studs. Tighten the clamps. The frame should not wobble.
-
Hang the blackout cloth first. This goes behind the impact screen. It blocks light bleed from the projector and cushions the ball. Use ball bungees every 12“ along the top rail. Pull it down snug. Wrinkles are fine — the impact screen covers them.
-
Mount the impact screen. Same bungee method, every 8–10“ along the top. Pull taut down the sides and bottom. You want it tight enough that a ball hitting center doesn’t sag more than an inch or two. Too tight and it tears. Too loose and balls pocket and come back at your shins.
Pro tip from the forums: leave 6“ of slack at the bottom and tuck it under a 2x4 or sandbag. This creates a “catch pocket” — the ball hits the screen, drops into the pocket, and rolls forward instead of bouncing back at your feet. One guy described it this way: “Bounce-back was deadly until I added a bottom shelf. Now the ball just drops. Game changer.”
Step 4: Mount the Projector
This is where it stops being a hitting net and starts being a simulator. A projector throws the image onto your impact screen so you can see the course, not just numbers on a phone.
Positioning the Projector
Projector placement is the most common screw-up in DIY builds. Here’s the rule: behind the player, above the swing plane, centered on the screen. Not off to the side. Not on the floor. Not in front of you.
For a typical garage with a 9’ wide screen and 10–12’ depth:
- The projector lens should be 10–14 feet from the screen
- Mounted 7–8 feet off the floor (above your swing, below the ceiling)
- Centered left-to-right on the screen
- Tilted down slightly (5–10°)
You need a short throw projector for this — a “throw ratio” of 0.5:1 or shorter. Standard throw projectors need 15–20 feet of clearance, which nobody in a garage has. Short throw means the projector sits closer to the screen and still fills it. You also don’t cast a shadow when you swing because the projector is above your swing plane — the light comes from over your head.
The Mount
-
Find a ceiling joist. Use a stud finder. If there’s no joist where you need it, screw a 2x4 across two joists and mount to that. Toggle bolts in drywall will fail. A 7-pound projector on your head mid-swing is a bad day.
-
Attach the universal mount. Most have a 1/4“-20 thread that screws into the projector. Confirm your projector has that thread. It almost certainly does.
-
Hang and adjust. Loosen the mount’s pivot. Turn the projector on. Adjust until the image fills the screen with minimal keystone — that’s the trapezoid distortion you get when the projector isn’t square to the screen. Try to fix alignment by moving the projector, not by using the digital keystone correction. Keystone correction shrinks your image and softens the focus.
-
Run the HDMI cable. Along the ceiling, down the wall, to your PC. Use cable clips. Don’t leave it dangling — you’ll trip or yank the projector.
-
Run power. Projectors pull 200–400W. Put it on its own surge protector. Don’t daisy-chain it off the same circuit as your PC and launch monitor. When the breaker trips (and it will if you overload it), everything goes dark mid-swing.

Step 5: Install the Hitting Mat
The mat is more important than you think. A bad mat will hurt your body. Not metaphorically. Your elbows. Your wrists. Your lower back. I’ve seen forum posts from guys who had to stop practicing because their $50 Amazon mat was transmitting impact shock straight up their arms.
Setup
-
Lay down rubber base mats first. Horse stall mats from Tractor Supply — 1/2“ to 3/4“ thick, 4’x6’, about $55 each. They absorb shock, keep the hitting mat from sliding, and protect your floor. Cut with a utility knife and straightedge. This is the unglamorous step that makes the whole setup feel solid.
-
Position the hitting mat so the hitting strip — the replaceable insert where you tee up — is centered on your stance. Your launch monitor placement is calculated from the ball position. Get this right before you tape anything down.
-
Secure the mat. Double-sided carpet tape or industrial Velcro strips. The goal is zero movement. If the mat shifts, your ball position shifts, and your launch monitor data drifts.
-
For radar-based launch monitors (Mevo+, Rapsodo): The radar unit sits behind the player, pointed at the screen. You need 8 feet minimum of clear space behind the hitting area. The radar tracks ball flight as it leaves the club, so it needs room to “see” the ball fly toward the screen.
-
For camera-based launch monitors (SkyTrak+, Bushnell Launch Pro, GC3): The unit sits in front of the hitting area, between you and the screen, 5–8 feet from the ball. The ball flies over the unit. The unit’s height off the floor matters — usually 6–18“, check your manual.
Step 6: Connect the Launch Monitor
This is the moment. The frame is built. The screen is taut. The mat is down. Now you plug in the brain.
Physical Placement (Quick Recap)
- Radar units (Mevo+, Rapsodo): Behind you, on a tripod, pointed at the screen.
- Camera units (SkyTrak+, Bushnell Launch Pro, GC3): In front of you, between you and the screen, on a stable stand.
Whatever you’re using — stable stand. A folding table that wobbles when you hit will ruin your data. A sandbag-weighted tripod or a dedicated mount is the right call.
Power and Connectivity
Modern launch monitors connect via USB, Wi-Fi, or Bluetooth to your PC, iPad, or phone. But here’s the universal advice from the forums:
-
Update the firmware before you hit a single ball. SkyTrak, Rapsodo, Bushnell — they all ship with outdated firmware. The first-day experience is night and day after an update. Do this while you’re still setting up. Don’t be the guy troubleshooting mid-swing on day one.
-
Use the recommended host device. SkyTrak wants a PC. Rapsodo wants an iPhone or iPad. Mevo+ works with anything but loves an iPad. Don’t fight the manufacturer’s recommendation. The forum is full of guys who bought a launch monitor that pairs best with a PC and then tried to run it on an old iPad. Don’t be that post either.
-
Calibrate. Every launch monitor has a calibration routine — usually hitting a few balls flat to set the baseline. Do it. Don’t skip because you’re excited. Bad calibration = bad data = you’ll blame the unit when it’s actually your setup.
Step 7: Software Setup
The software turns your ball data into a golf course. Without it, you’re just hitting into a screen and seeing numbers. With it, you’re at St. Andrews at midnight.
Software Options by Tier
| Software | Price | Best For |
|---|---|---|
| Rapsodo app | Free (with MLM2Pro) | Mobile-only. 16 courses. Easy. No PC needed. |
| SkyTrak Range & Plan | $199/yr | SkyTrak owners. Range + course play. Solid. |
| E6 Connect | $300–$600/yr | Mid-tier PC users. 100+ courses. Widely supported. |
| GSPro | $400+/yr | Premium PC users. Best physics in the price range. 4,000+ courses. |
| TGC 2019 (Creative Golf) | $1,000 once | Course junkies. 150,000+ community courses. Ugly UI. |
| Awesome Golf | $200–$400/yr | Cross-platform. Casual. Family-friendly. |
The forum consensus is overwhelming: GSPro at $250 to $400 a year is the best value. 4,000+ courses, active development, a mod community that adds new courses weekly. But here’s something guys miss: a $250/year subscription is $1,250 over five years. TGC 2019 at $950 one-time starts looking smart if you’re in it for the long haul.
Setup Steps (Universal)
- Install the software on your host device — PC, iPad, or phone.
- Pair the launch monitor using the software’s connection flow. Usually a one-time thing.
- Set your environment — room dimensions, screen distance, tee height. This matters because the software uses these numbers to render ball flight correctly. Wrong dimensions = the virtual ball doesn’t match what your launch monitor measured.
- Run a calibration session. Hit 5–10 balls straight and confirm the on-screen flight matches reality. If you’re hitting a push-draw and the screen shows a straight pull, your room dimensions or calibration is off.
- Adjust the camera view in the software. Pick follow cam, top view, or ball cam. Whatever feels natural.
Common DIY Golf Simulator Mistakes (and How to Avoid Them)
Every builder makes at least one of these. Here’s the list so you don’t have to.
1. Buying Components Before Measuring the Room
I said this in Step 1. I’m saying it again because it’s the #1 post on the forums, every single week. A guy buys a screen. Gets it home. Realizes his garage has a 7’6“ clearance because of a duct run he never noticed. Now he’s selling a used screen on Facebook Marketplace.
Measure first. Buy second. I’m begging you.
2. Mounting the Projector Wrong
Three common flavors of disaster:
- Too close to the screen → tiny image, can’t focus.
- Off to the side → massive keystone, image is a trapezoid.
- In front of the player → you cast a shadow on every swing.
Fix: behind the player, above the swing, centered on the screen. Short throw projector. Ceiling mount.
3. Skimping on the Enclosure Frame
PVC is cheaper. PVC also flexes. A 100mph driver hit on a PVC frame will bow inward, the ball will pocket, and eventually the pipe cracks. Use EMT conduit or wood. EMT is cheap, rigid, and at any hardware store. Wood is even more solid but takes longer.
4. Ignoring Ball Bounceback
Balls hit an impact screen and come back. If your screen is too tight and you hit dead center, the ball comes back 3–6 feet. The fix: a catch pocket at the bottom (Step 3 covers this), and aim slightly off-center. Wear safety glasses during testing. “It’s not paranoid,” one forum builder said. “We’ve seen a ball come back and break eyeglasses.”
5. Wrong Launch Monitor for the Space
Radar unit (Mevo+) in a 9’ deep room won’t track well — it needs room behind the ball. Camera unit (SkyTrak) in a 6’ deep room will get hit by the ball because it sits in front of you. Match the launch monitor to your room. Radar wants room behind. Camera wants room in front.
6. Not Protecting the Floor
Real golf balls on concrete bounce. On tile, they crack it. On hardwood, they dent it. Lay down rubber mats across the whole hitting zone, not just under the hitting mat. A 4x6 stall mat is $55 and saves your floor. And your marriage, if the simulator is in the house.
Troubleshooting Guide
Stuff breaks. Here’s the cheat sheet.
“The image on the screen is blurry / out of focus”
- Move the projector. Short throws have a tight focus range. Shift it 6“ forward or back and re-focus.
- Check the screen material. Projecting onto a net instead of an impact screen? The image will always be soft. Impact screens are made for projection. Nets aren’t. (See our comprehensive 2026 impact screen guide for the full breakdown of fixed, retractable, and enclosure-integrated screens.)
- Wipe the lens. Garage dust settles on everything. A microfiber cloth fixes a shocking number of “blurry” complaints.
“The launch monitor is mis-reading my shots”
- Re-calibrate. 80% of “my launch monitor is broken” complaints are “I never calibrated it.”
- Check lighting. Camera-based units (SkyTrak, Bushnell, GC3) need decent light. A dark garage will tank accuracy. Add a floodlight overhead, pointed at the hitting area, not directly at the launch monitor. (See Best Lighting for Golf Simulators → for setup plans.)
- Check ball position. If you’ve drifted a foot to the left since calibration, the launch monitor is reading a different position than expected. Keep the ball in the same spot. Use a tee.
“The screen is sagging”
- Tighten the bungees. Screens stretch over time, especially the first month. Re-tension every 8–10“ along the top rail.
- Add a bottom weight. A 2x4 or sandbag along the bottom edge keeps the screen taut.
- Check the frame. If the frame is bowing, add more cross-bracing in the back plane.
“Balls are bouncing back at me”
- Loosen the screen tension slightly. A too-taut screen acts like a trampoline.
- Add a catch pocket. Fold the bottom 12“ of the screen forward to create a shelf.
- Hit above center. The ball drops instead of rebounding.
“The projector keeps shutting off”
- It’s overheating. Clean the air filter. If that doesn’t fix it, the projector is past its lifespan. Lamp-based projectors die after 3–5 years. Time to upgrade to LED or laser.
“The software is lagging”
- Close other apps. Simulator software is heavy. Don’t run Chrome with 40 tabs.
- Check your PC specs. E6 Connect wants a 1660 GPU minimum. GSPro wants a 2060 or better.
- Drop the resolution. 720p looks fine and runs smooth.
Final Thoughts: You Can Actually Build This
A DIY golf simulator is not a small project. But it is a very achievable one. The framing takes a Saturday. The projector and software take a Sunday. The launch monitor pairing takes an evening. Total: a long weekend for budget, two weekends for mid-tier, three for premium with custom wiring.
The payoff is not theoretical. You’ll hit balls in January while it’s snowing. You’ll practice without paying $25 for a bucket. Your kids will think you’re a wizard. Your garage becomes the place every golf buddy wants to visit. And you built it yourself — with your hands, from conduit and bungee cords and a screen you tensioned yourself.
When something breaks in two years, you’ll know exactly which bungee to replace, which lag to re-tighten, which cable to re-run.
That’s the whole point. Not just the savings. The ownership.
One more thing from the forums, from a guy who finished his build and posted the photos:
“Light rain outside, 3 AM, I’m on 18 at St. Andrews.”
A garage that used to hold lawnmowers and bikes nobody rides. Now it holds a course. And you built it.
Now go measure your room. Then buy your conduit. Then build.
You’ll be on 18 at St. Andrews by next weekend.
Frequently Asked Questions
Can I build a golf simulator for under $1,000?
Yes, but it’s a net-and-launch-monitor combo, not a full enclosure build. Rapsodo MLM2Pro ($549) + a decent net ($150) + your phone = functional setup for under $800. You don’t get the big screen. You get real ball data and course play on your phone. It’s how most guys start.
Do I need a PC, or can I use an iPad?
Depends on the launch monitor. Rapsodo is iPad only. Mevo+ works on anything. SkyTrak wants a PC. Use the manufacturer’s recommendation. Don’t fight it.
How long does the build actually take?
Budget build: a long weekend. Mid-tier with projector and enclosure: two to three weekends. Premium with custom wiring: a month of evenings. The frame and screen are the slow parts. Everything else is an afternoon.
Is it worth it vs. buying a pre-built package?
Financially yes — you save 30–50% on the enclosure and installation. Practically yes — you understand the system and can fix it. The exception: above $8K, the DIY savings shrink, and a pre-built starts making sense if your time is worth more than the money.
Can I use a TV instead of a projector?
Yes. Many people do, especially for net-only setups where there’s no impact screen. A 55–65“ TV beside the net shows your ball flight and course. You lose the immersive feel. You save $300+.
What’s the most important part of the build?
The launch monitor. If you only have money for one good thing, spend it there. Frame, screen, projector, mat — all upgradeable later. The launch monitor is the brain. A bad brain makes the whole system useless.
