What Size Room Do You Need?
The absolute minimum for a golf simulator is 10 feet wide ร 10 feet deep ร 9 feet tall. That's tight โ you'll be limited to shorter clubs and won't have room for a projector behind you. A 12ร15 room with 9.5-foot ceilings is where things get comfortable. And if you've got a 15ร20 space, you can build a setup that rivals a commercial sim bay. Below, I've mapped out floor plans for each of these room sizes with exact component placement.
Minimum Dimensions for a Golf Simulator
Before you start sketching floor plans, you need to know the hard limits. These aren't suggestions โ they're the measurements where things physically stop working.
Width: 10 Feet Minimum (12+ Preferred)
Width is about swing clearance. Stand at address, extend your driver to the top of the backswing, and measure from the clubhead to the nearest wall. You need at least 18 inches of clearance on each side. For most golfers, that means 10 feet minimum width. If you're over 6'2" or have a very flat swing plane, bump that to 12 feet. I've personally clipped a wall stud swinging a 5-iron in a 9.5-foot-wide space โ trust me, you want the buffer.
Depth: 12 Feet Minimum (15+ Preferred)
Depth is the trickiest dimension because it has to fit three things in a line: the impact screen at the front, you in the middle, and ideally a projector behind you. A 10-foot room technically works with a net-only setup (no projector), but 12 feet is the real minimum for a projector + screen setup using a short-throw projector. At 15 feet of depth, you can use a standard throw projector and have room to step back and watch your shot land.
Height: 9 Feet Minimum (10+ Preferred)
Ceiling height kills more simulator dreams than any other dimension. A standard 8-foot ceiling won't work for most golfers swinging a driver โ the club will hit the ceiling on the backswing. You need at least 9 feet, and even then, taller golfers (6'+) should test their swing arc before committing. A 10-foot ceiling is the sweet spot where virtually any golfer can swing any club without restriction. Check our ceiling height guide for the exact math based on your height.
Dimension Quick Reference
| Room Size | Width ร Depth | Min Ceiling | What Fits |
|---|---|---|---|
| Bare Minimum | 10' ร 10' | 9' | Net + launch monitor only |
| Tight but Workable | 10' ร 12' | 9' | Short-throw projector + screen |
| Comfortable | 12' ร 15' | 9.5' | Full enclosure + projector |
| Ideal | 15' ร 15' | 10' | Full enclosure + seating area |
| Premium | 15' ร 20'+ | 10' | Multiple hitting bays or lounge |
Where Everything Goes: Component Placement Rules
Every golf simulator floor plan arranges the same five components. Get these distances right and your build will feel natural from day one.
Impact Screen
The screen goes against the far wall (the wall you're hitting toward). Leave 6-12 inches between the screen and the wall to absorb ball impact and prevent the ball from bouncing back at your feet. If you're using a standalone impact screen, you'll need a frame that sits about 12 inches off the wall. Full enclosures like the SIG8 have the screen built into the frame.
Hitting Mat
Place the hitting mat so the ball position is 7-10 feet back from the impact screen. Closer than 7 feet and the ball doesn't have time to spread on the screen (you get a concentrated hot spot that wears through faster). Further than 10 feet and you're wasting depth you could use for projector placement or a seating area.
Launch Monitor
This depends entirely on your launch monitor type. Radar-based units like the Garmin R10 sit 6-8 feet behind the ball on the floor. Camera-based units like the Bushnell Launch Pro or SkyTrak+ sit beside or slightly behind the ball. Overhead units mount to the ceiling directly above the hitting area. Factor your monitor's placement into your depth calculation.
Projector
Short-throw projectors mount 3-5 feet from the screen, either on a ceiling mount or shelf. Standard throw projectors need 8-12 feet from the screen and typically mount on the ceiling behind the golfer. The right projector depends almost entirely on your room depth. If you've got under 12 feet total, you're looking at a short-throw โ no way around it.
PC or Laptop
Put the PC to the side of the hitting area, never directly behind where you're swinging. A small desk or shelf against the side wall works. Keep cable runs clean โ an HDMI cable from the PC to the projector (often 15-25 feet for ceiling-mounted projectors) and USB to the launch monitor.
Small Room Floor Plan (10ร10)
A 10ร10 room is the smallest space that works. You'll make compromises, but you can still get meaningful practice in.
What Fits
- Net or basic impact screen โ no room for a full enclosure frame in most cases
- Hitting mat โ positioned 7 feet from the net
- Launch monitor โ side-mounted (camera-based) or directly behind (radar), but a radar unit behind you eats your remaining 3 feet of depth
- No projector โ unless you ceiling-mount an ultra-short-throw, there's simply no throw distance. Use a tablet, laptop, or TV mounted to the side wall instead
Layout Notes
In a 10ร10, you're essentially standing in the back third of the room hitting into a net on the far wall. That's it โ and honestly, that's enough for iron work, chipping practice, and swing speed training. I'd pair this setup with a Garmin R10 sitting on the floor behind you and a tablet on a side shelf for data. Total depth budget: 1 foot for the net, 7 feet of ball flight, and 2 feet behind you for stance and the monitor. It's tight but it works.
Best For
Spare bedrooms, large walk-in closets, apartment corners, or apartment setups where space is fixed and you just want to hit balls and see data.
Medium Room Floor Plan (12ร12)
At 12ร12, a proper golf simulator becomes realistic. This is where the floor plan actually starts to matter because you have enough depth for a projector setup.
Layout Breakdown (Front to Back)
- 0-1 feet: Wall gap + impact screen
- 1-3 feet: Enclosure frame depth (if using full enclosure)
- 3-4 feet: Short-throw projector mounted to ceiling (3-4 feet from screen)
- 4-5 feet: Open space (ball flight zone)
- 5-8 feet: Hitting mat + ball position (ball at ~8 feet from screen)
- 8-10 feet: Stance zone
- 10-12 feet: Radar launch monitor on floor + stepping room
Projector Options
With 12 feet of depth, a short-throw projector ceiling-mounted at 3-4 feet from the screen is your only real option. The Optoma GT2000HDR ($974) does this well โ it throws a 100-inch image from about 3.5 feet. Mount it to the ceiling between the screen and the hitting position, angled slightly downward.
Enclosure Pick
The SIG8 Enclosure is built for rooms like this. It's 8.5 feet wide, 5 feet deep, and 8.5 feet tall โ leaving you with roughly 7 feet behind the enclosure for your stance and monitor. That's snug but functional.
Best For
Dedicated simulator rooms, finished basements, and spare rooms where you can commit the full space to the setup.
Ideal Room Floor Plan (15ร15)
15ร15 is the sweet spot where everything fits comfortably and you stop making compromises. I'd call this the "no regrets" room size.
Layout Breakdown (Front to Back)
- 0-1 feet: Wall gap behind screen
- 1-5 feet: Full enclosure with impact screen and side netting
- 5-8 feet: Open ball flight zone
- 8-9 feet: Hitting mat
- 9-11 feet: Golfer stance + swing arc
- 11-13 feet: Radar launch monitor zone
- 13-15 feet: Projector (standard throw) or seating area
Why 15ร15 Works So Well
You've got enough width (15 feet) for a full enclosure centered in the room with 3+ feet of clearance on each side. That clearance matters for two reasons: safety (a shank won't hit the side wall) and access (you can walk around the enclosure without squeezing). The 15-foot depth means you can choose between a standard throw projector behind you or a short-throw projector near the screen โ either works, which gives you more projector options at better price points.
The "Lounge" Option
With 15 feet of depth, there's enough room to put a small couch or bar-height table and stools behind the hitting area. If you're building a man cave setup, this is where the room starts functioning as entertainment space, not just a hitting bay. Tuck a mini-fridge against the back wall, mount a second screen above it for live golf, and you've got a room people actually want to hang out in.
Best For
Dedicated basement rooms, two-car garages (depth-wise), and purpose-built additions where you're designing the room around the simulator.
Large Room Floor Plan (15ร20+)
Once you're past 20 feet of depth or 15+ feet of width, you're in premium territory. The simulator itself doesn't need more space โ you're designing a room experience.
What the Extra Space Gets You
- Putting green area: A 4ร10 foot putting mat behind or beside the hitting area gives you a complete short game station
- Comfortable lounge zone: Full couch, coffee table, and TV for watching real golf while you wait for your turn
- Club storage: Wall-mounted bag rack or rolling bag stand against the side wall
- Secondary hitting position: In a 20+ foot wide room, you could theoretically set up two bays side-by-side โ but at that point you're basically building a commercial space
Component Distances in a Large Room
Don't spread the core components just because you have space. The screen-to-ball distance should still be 7-10 feet, and the ball-to-monitor distance stays the same regardless of room size. What changes is the buffer zone and amenity space behind the hitting position. A 20-foot room gives you roughly 8-10 feet behind the hitting mat โ that's where your entertainment zone lives.
Best For
Three-car garages, unfinished basements with open spans, outbuildings, and purpose-built simulator sheds.
Garage Floor Plans
Garages are the most common simulator location โ and the most complicated floor plans because you're often sharing the space with a car.
Single-Car Garage (10ร20)
A single-car garage is usually about 10 feet wide and 20 feet deep. The width is tight (exactly at minimum), but the depth is generous. Set up the screen on the far wall, and you'll have plenty of room behind the hitting area. The challenge is width โ you might clip the side wall with a flat swing. Consider a retractable screen setup so you can still park when you're not hitting. Our garage golf simulator guide covers retractable options in detail.
Two-Car Garage (20ร20)
This is the goldilocks garage. With 20 feet of width, you can set up a full enclosure on one side and still park a car on the other โ or go all-in with a centered build and a lounge area. Most golfers I've talked to who build in a two-car garage end up dedicating the full space within six months. Start with one side, accept that the car will end up in the driveway permanently.
Shared-Use Considerations
If you need to park in the garage too, the floor plan changes entirely. You need a retractable screen that folds up to the ceiling, a hitting mat that stacks against the wall, and a launch monitor small enough to toss in a drawer. The Garmin R10 is perfect for this โ it's the size of a deck of cards. Your "floor plan" becomes more of a setup/teardown routine that takes 5-10 minutes.
Ceiling Height Rules for Your Floor Plan
You can adjust width and depth by choosing different equipment. You can't adjust ceiling height without major renovation. This is the non-negotiable dimension in any floor plan.
The Height Formula
Stand upright, extend your lead arm straight up holding a driver. Measure from the floor to the clubhead. Add 6 inches. That's your absolute minimum ceiling height. For most golfers between 5'8" and 6'0", this lands between 9 and 9.5 feet. Golfers over 6'2" typically need 10+ feet.
| Your Height | Minimum Ceiling | Comfortable Ceiling |
|---|---|---|
| 5'6" and under | 8.5' | 9' |
| 5'7" โ 5'11" | 9' | 9.5' |
| 6'0" โ 6'2" | 9.5' | 10' |
| 6'3" and over | 10' | 10.5'+ |
Standard residential ceilings are 8 feet. That's too short for virtually everyone swinging a driver. Basements with drop ceilings are often 7.5 feet โ definitely too short. Garages typically range from 8-10 feet depending on the door tracks. If you're between heights, always round up. Hitting the ceiling once with a driver is a mistake. Hitting it twice means you should've measured better. Check our complete ceiling height guide for a deeper breakdown.
What if Your Ceiling Is Too Low?
You've got three options: remove a drop ceiling to expose the joists (often gains 6-12 inches), choke down on longer clubs (not ideal but functional), or limit your simulator to irons and wedges only (actually great for scoring practice). Some golfers with 8.5-foot ceilings use their simulator exclusively for short game work and take the driver to the range.
Left-Handed Floor Plan Adjustments
If you're a lefty (or sharing the simulator with both left and right-handed golfers), your floor plan needs a few tweaks.
Width Matters More
A right-handed golfer's follow-through swings toward the left wall. A lefty's goes toward the right. If your room is exactly at the 10-foot minimum width, one orientation might work while the other doesn't โ depending on which wall has pipes, electrical boxes, or other obstructions. Measure clearance from both sides before committing to a layout.
Camera-Based Monitor Placement
Camera-based launch monitors like the SkyTrak+ and Bushnell Launch Pro need to be repositioned when switching between lefty and righty. Build your floor plan with easy access to both sides of the hitting mat. Some golfers mount a small table on each side and just move the monitor. Radar-based units like the Garmin R10 sit directly behind you regardless of handedness โ one less thing to adjust.
The Mixed-Use Solution
If you're building for a household with both lefties and righties, center the hitting mat in the room with equal clearance on both sides. Don't push the setup toward one wall to gain lounge space โ you'll regret it when the lefty in the family can't swing freely.
