The Simple Formula: Subtract 5 Feet from Each Dimension
Measure your room wall-to-wall. Subtract 5 feet from each dimension (2.5 feet of cue and swing clearance per side). The result is the maximum enclosure and screen size that fits comfortably. Use this before looking at anything else.
Example: 14 ft wide × 18 ft deep room → fits up to a 9 ft wide enclosure with 16 ft of depth ✓

Minimum, Ideal & Premium Room Dimensions
These are the three tiers most home simulator builds fall into. If you're close to the minimum, you can still build a great setup — but you'll need a short-throw projector and careful enclosure sizing.
Minimum — Tight but workable
Width10 ft
Ceiling Height9 ft
Depth12 ft
Screen WidthUp to 8 ft
Restricted to irons and mid-irons. Driver swings require 10 ft ceiling. Short-throw projector required. Tight side clearance — 1 ft each side.
Ideal — Comfortable for all clubs
Width12–15 ft
Ceiling Height10 ft
Depth15–18 ft
Screen Width9–10 ft
Full driver swings, comfortable side clearance, projector flexibility. The sweet spot for most home builds — fits a 9 or 10 ft wide enclosure easily.
Premium — Full freedom
Width16+ ft
Ceiling Height10–12 ft
Depth20+ ft
Screen Width12 ft+
Immersive wide-screen experience, full projector placement flexibility, generous side clearance. Also allows for overhead launch monitor mounting.

Most Common Limitation
Ceiling Height by Club Type
Ceiling height is the most common reason home simulator builds fail — or get downgraded. Here's the exact clearance needed for each type of club, with zero margin for error.
8 ft
Not recommended
Below safe minimum for any full swing. Restricted to chipping and putting practice only.
8.5 ft
Short irons only
Wedges and 9-iron only. Not suitable for anything longer. Risk of club strike on ceiling.
9 ft
Irons & hybrids
Minimum for mid-irons through long irons. Driver swings are marginal — tall players should be cautious.
9.5 ft
Most full swings
Safe for most players with irons through fairway woods. Driver is possible for shorter players.
10 ft
All clubs incl. driver
The recommended minimum for unrestricted driver swings for most players. The target height for most home builds.
11–12 ft
Full freedom + overhead mounts
Ideal for tall players and overhead launch monitor mounting (Uneekor EYE XO etc.). Maximum comfort.
Garage door tracks: If you're building in a garage, subtract the height of any horizontal door tracks from your usable ceiling height. Tracks typically hang 12–18 inches below the ceiling and will interfere with enclosure frame height and screen placement. Measure from the floor to the bottom of the track, not the ceiling.
Side Clearance
Room Width Requirements
Width is often overlooked — buyers focus on ceiling height and depth but forget that the swing arc needs side clearance too. The enclosure also needs a few inches of buffer from each wall for installation.

Right-handed vs left-handed players: If you have both in your household, the swing arc extends more to the right for a right-handed player and vice versa. For mixed households, aim for at least 2 ft of clearance on each side rather than 1.5 ft on one side.
Depth & Projector Throw
Room Depth: Ball Flight & Projector Space
Room depth serves two purposes: space for the golfer to stand behind the hitting mat, and space for the projector to project an image large enough to fill the screen. Both matter and both are constrained by your total room depth.
Enclosure Depth
4–6 ft
The depth of the enclosure itself — from the screen to the back netting. This is fixed by the enclosure you choose.
Golfer Standing Space
3–5 ft
The space between the back of the enclosure and the wall behind the golfer. Minimum 3 ft, 5 ft is comfortable.
Projector Throw (Ultra Short)
1–2 ft
Ultra-short-throw projectors mount directly above the screen or just behind it. Best option for tight rooms.
Projector Throw (Short)
4–8 ft
Standard short-throw projectors mount 4–8 ft from the screen, typically above or behind the golfer's position.
Total minimum depth calculation: Add enclosure depth (5 ft) + golfer space (3 ft minimum) + projector throw (depends on projector type). For a standard short-throw setup: 5 + 3 + 5 = 13 ft minimum total room depth. For an ultra-short-throw setup: 5 + 3 + 1 = 9 ft minimum.
Don't forget the hitting mat: The hitting mat sits inside or just in front of the enclosure. It extends 2–4 ft behind the hitting position. Factor this into your golfer space calculation — you need clearance from the mat edge to the back wall, not just from the enclosure.
Room-Specific Guidance
Garages vs Basements: What Changes
The physical requirements are identical — what changes is what you need to watch out for in each space. Here's what matters specifically in each room type.
🏠Garage Builds
⚠Door track height: Horizontal tracks hang 12–18" below ceiling. Measure to bottom of track, not ceiling.
⚠Garage door opener: The motor and arm take up central ceiling space. Plan your enclosure frame around it.
✓Standard 2-car garage: 20 ft wide × 20 ft deep is ideal for a 12 ft screen with comfortable clearance.
✓Standard 1-car garage: 10–12 ft wide × 20 ft deep. Fits an 8–9 ft enclosure with tight side clearance.
⚠Projector brightness: Garages often have ambient light leaking under doors. Choose a projector rated 3,000+ lumens.
⚠Temperature: Unheated garages affect play in winter and can damage some launch monitors. Consider a small unit heater.
✓Flooring: Concrete is fine under a hitting mat. Add a rubber underlayment for joint comfort on extended sessions.
🏚Basement Builds
⚠Ductwork and beams: Measure to the lowest obstruction, not the ceiling. Exposed joists and HVAC can reduce usable height significantly.
✓Controlled environment: Basements stay cooler and darker than garages — better for projector image quality year-round.
⚠Egress windows: May limit where you can place the screen and enclosure. Ensure nothing blocks emergency exit paths.
✓Noise: Below-grade rooms naturally absorb more sound. Ball impact noise is less likely to disturb the rest of the house.
⚠Moisture: Check for humidity issues before installing. High humidity affects hitting mat longevity and some electronics.
✓Typical finished basement: 8–9 ft ceiling is common. Budget for irons-only setup or check if joists allow 10 ft in any area.
⚠Stair clearance: Getting equipment down basement stairs can be challenging. Measure stairwell width before ordering a large enclosure kit.

Common Questions
Frequently Asked Questions
An 8-foot ceiling is below the safe minimum for any full swing. At this height, the risk of striking the ceiling on a normal iron swing is significant, and a driver swing is impossible for most adult players. You can use a launch monitor for chipping and putting practice, but a full enclosure and screen setup is not practical at this ceiling height. If your only available space has an 8-foot ceiling, a net setup without a projector is a safer option that still allows ball flight data capture with a launch monitor.
Measure from the floor to the bottom of the horizontal door tracks — not the ceiling. Tracks typically hang 12–18 inches below the ceiling. A 10-foot ceiling with 15-inch tracks gives you approximately 8.75 feet of usable height in the track area. However, the tracks only span part of the garage width and length — you may be able to position your hitting position in an area not directly under the tracks. Sketch your garage layout before ordering any equipment and mark where the tracks are relative to where the golfer would stand.
The minimum is 3 feet from the back of the hitting mat to the back wall of the enclosure or room — this allows a normal stance and a comfortable backswing without stepping outside the hitting area. Five feet is comfortable and allows most players to take a full, relaxed setup. Seven feet or more is ideal and eliminates any feeling of being cramped behind the ball. For players over 6 feet tall or with a wide stance, add an extra foot to each figure.
A few inches under the minimum in width or depth is usually workable with some adjustments — placing the hitting position closer to center, choosing a slightly smaller enclosure, or using an ultra-short-throw projector to reduce depth requirements. Ceiling height is less forgiving — being 6 inches under the minimum for driver swings is a real problem that smaller enclosures can't solve. When in doubt, use our compatibility checker or contact us before ordering — it's better to know your constraints before you buy than after.
Yes, slightly. A right-handed golfer's swing arc extends to the right of their body (toward the target side), so they need slightly more clearance on the right wall. A left-handed golfer needs more clearance on the left wall. For mixed households where both orientations are used, aim for at least 2 feet of clearance on each side rather than the minimum 1.5 feet. The screen and enclosure don't move — the golfer just positions slightly off-center when needed.
A standard projector requires 10–15 feet of throw distance to produce a large enough image for a simulator screen — which means it would need to be mounted 10–15 feet from the screen, typically behind the golfer in the back of the room. This works in large rooms (20+ ft deep) but is impractical in most home setups. Short-throw projectors need 4–8 feet and can be mounted above or just behind the golfer's position. Ultra-short-throw projectors need just 1–2 feet and mount near the screen. For most home builds, a short-throw or ultra-short-throw projector is the right choice — the additional cost is offset by the flexibility it gives you in room layout.
