Golf Simulator Enclosure Guide: Nets, Screens and Sizing
The enclosure is the part of a home setup nobody gets excited about, and the part that ruins the most builds when it goes wrong. I have framed out enclosures in garages, basements and one very tight spare bedroom, and the same two mistakes show up every time: people buy a screen that is too small for their room, and they skip side containment until a thinned wedge marks the drywall. Get the enclosure right and everything else (your launch monitor, your hitting mat, your projector) just drops into place.
Quick verdict: if you only want to groove a swing, a net and your phone are plenty and cost a couple hundred bucks. If you want to project a course and live in the sim, you need a real enclosure with a proper impact screen, a frame, and side barriers. For screens and DIY kits, Carl's Place is the name that keeps coming up for a reason. Here is how to spec it without overbuying.
Net or full enclosure: which one do you actually need?
Start here, because this decision sets your budget. A net catches balls. An enclosure catches balls, holds a projected image, and contains the mess so you can play in a finished room.
A net is enough when you mostly want feedback numbers and reps. Pair a net with a Garmin Approach R10 or your phone, hit into it, and read your carry and dispersion. That is real practice. For a lot of golfers, this is the honest answer and it saves a few thousand dollars. A full simulator is a indulgence rather than essential gear, and there is no shame in starting with a net.
You want a full enclosure when you plan to project a course in software like GSPro or E6 Connect and play 18 indoors. Now you need a flat impact screen that doubles as your projection surface, a frame to keep it tight, and barriers so off-center hits do not leave the bay. If that is the goal, read our impact screen guide next, because the screen is the single most visible part of the build.
- Net only: roughly $150 to $500, practice and numbers, no projected course.
- Enclosure with screen: roughly $700 DIY to $3,000-plus premium, full projected play.
Impact screen, in brief
The impact screen is its own decision with real trade-offs in material, brightness and ripple, so I cover it in full separately. The short version: a heavier multi-layer screen lasts longer and ripples less under fast ball speeds, and it needs to be sized and tensioned to your frame. For materials, image quality and sizing, read the full impact screen guide.
Sizing the enclosure to your room
This is where most builds go sideways. Measure your room first, then buy the screen, never the other way around. A screen that is an inch too tall will not let you tension it, and a bay that is too narrow forces you to choke your swing.
A comfortable bay is about 10 ft wide by 12 ft deep by 9 to 10 ft tall. Minimum ceiling is about 9 ft, and 10 ft is what you actually want so a tall player can swing a driver without clipping anything. The width matters more than people expect, because you need clearance for both a right-handed and a left-handed swing if more than one golfer will use it. Get under 9 ft of ceiling and you are into shortened backswings, which defeats the point.
Depth depends on your launch monitor. Radar units like the FlightScope Mevo+ and the Garmin R10 read the ball in flight and want roughly 8 to 16 ft of distance from the ball to the screen, so they push your enclosure deeper. Photometric units like the Bushnell Launch Pro and the SkyTrak+ sit beside the ball and read it at impact, so they fit tighter rooms and let you stand closer to the screen. Overhead units like the Uneekor EYE XO mount in the ceiling and free up floor space entirely. Pick your monitor with your room dimensions in mind, then size the enclosure around both.
| Room dimension | Minimum | Comfortable |
|---|---|---|
| Ceiling height | 9 ft | 10 ft |
| Bay width | 9 ft | 10 to 12 ft |
| Bay depth | 10 ft | 12 to 16 ft |
DIY frame vs premium kit
You have two real paths for the frame that holds the screen: build it yourself from pipe and conduit, or buy a complete kit.
A DIY frame is usually EMT conduit or galvanized pipe with corner fittings, the kind you can cut at any hardware store. A conduit frame for a standard bay runs roughly $150 to $300 in parts, and you pair it with a screen sold separately. This is the budget-smart route and it is genuinely sturdy if you brace the corners. Carl's Place sells screens plus the connector kits and instructions to build the frame yourself, which takes most of the guesswork out. If you want the full parts list and build steps, see our DIY golf simulator guide. You can pick up a screen and DIY hardware together at Carl's Place.
A premium kit ships as a complete enclosure: frame, screen, side barriers, and the padding, all sized and ready to assemble. Expect roughly $1,500 to $3,000-plus depending on size and quality. You pay for the convenience, the finished look, and not having to source a dozen fittings. If you are not handy or you want it to look clean in a finished basement, a kit is worth the money. If you have a drill and an afternoon, DIY saves a real chunk.
Safety, ball containment and side barriers
This is the part people skip and then regret. The screen handles the straight shots. The shots you need to plan for are the ones that miss the screen entirely, the toe shanks and the heel hits that fly sideways. Without side containment, those find drywall, windows, and once in my case a water heater.
Side barriers are panels or netting that run down both sides of the bay from the screen back toward the hitting area. A good enclosure wraps the screen on the top and both sides so a mishit gets caught no matter where it goes. Premium kits include this. If you go DIY, do not treat the barriers as optional, they are the difference between a safe room and a hole in the wall.
- Wrap the sides and top, not just the front, so off-line shots stay contained.
- Leave a buffer behind the screen. A ball can deflect off the frame, so keep the screen a few inches off any wall.
- Check your ceiling clearance on the backswing. Lights and fans are the most common casualties in a low room.
- Use real golf balls only at safe distances. Foam balls are fine for a tight net but read poorly on radar units that need ball flight.
One more honest note: foam and restricted-flight balls are gentler on the room, but radar units like the R10 and Mevo+ struggle to read them because they depend on real ball flight. Photometric units handle limited-flight balls better since they read at impact. Match your ball to your monitor, not just to your nerves.

Frequently asked questions
Do I really need an impact screen, or is a net enough?
It depends on your goal. A net catches balls and, paired with a launch monitor or your phone, gives you real practice with carry and dispersion numbers. That is enough for many golfers. You only need an impact screen if you want to project a course in software like GSPro and play full rounds indoors. The screen is what turns a practice net into a simulator.
What causes ripple in the projected image?
Ripple is uneven tension across the screen, and it is almost always a mounting issue rather than a bad screen. Use bungee cords around the perimeter spaced every 6 to 8 inches so the screen stays flat for the picture but can still flex on impact. Avoid fixed grommets or zip ties, which create waves and lead to early tearing at the center.
How much room do I need for a golf simulator enclosure?
A comfortable bay is about 10 ft wide by 12 ft deep by 9 to 10 ft tall. Minimum ceiling is roughly 9 ft, but 10 ft lets a tall player swing a driver freely. You also need width for both right-handed and left-handed clearance. Radar launch monitors want more depth than photometric units, so size your room around your monitor.
Is a DIY conduit frame as good as a premium kit?
For most builds, yes. A braced EMT conduit or galvanized pipe frame is sturdy and runs about $150 to $300 in parts, paired with a screen bought separately. A premium kit costs $1,500 to $3,000-plus but ships complete with barriers and padding, sized and ready. Choose DIY if you are handy and want to save, or a kit if you want a finished look with no sourcing.
What side barriers do I need for safety?
You need netting or panels running down both sides of the bay and across the top, not just the screen in front. Mishits fly sideways and will find drywall, windows, or lights if the sides are open. Keep the screen a few inches off any wall so deflected balls have a buffer, and check your ceiling clearance on the backswing before the first swing.
