How to Build a Golf Simulator Room: Complete Space Requirements Guide

Quick Reference: Minimum Dimensions

Before diving into the details, here are the space requirements at a glance:

| Room Type | Width | Depth | Ceiling Height | |-----------|-------|-------|----------------| | Minimum Playable | 10 ft | 12 ft | 9 ft | | Recommended | 12 ft | 15 ft | 10 ft | | Ideal | 15 ft | 18 ft | 10+ ft | | Commercial Standard | 15 ft | 20 ft | 12 ft |

The critical measurement is ceiling height. You can work around limited width and depth, but low ceilings fundamentally restrict which clubs you can swing safely.

Understanding Space Requirements

Why Dimensions Matter

A golf simulator room needs to accommodate three things:

Your golf swing - Full range of motion without hitting walls or ceiling
The technology - Screen, projector, launch monitor positioning
Ball flight - Space for the ball to reach the screen

Getting the dimensions wrong leads to frustration at best and injury or damage at worst. Players who can't swing freely develop compensations that hurt their real game.

Minimum Room Size: 10 x 12 x 9 feet

This is the absolute minimum for a functional simulator. At these dimensions:

Width (10 ft): Tight but workable for right-handed players hitting into the center. Left-handed players may feel cramped. No room for spectators alongside the hitter.
Depth (12 ft): Accommodates the hitting position (4-5 ft from screen) plus standing room behind. Most launch monitors need 6-10 feet behind the ball, which gets tight.
Ceiling (9 ft): The limiting factor. Many golfers can swing a driver at 9 feet, but taller players (6'2"+) may need to modify their swing. Long irons become risky.

Who this works for: Compact basement spaces, single-car garages, dedicated home gym conversions. Best suited for practice-focused setups where you're primarily hitting shorter clubs.

Recommended Room Size: 12 x 15 x 10 feet

This is the sweet spot for most home simulators. The extra space transforms the experience:

Width (12 ft): Comfortable for both right and left-handed players. Room for a chair or small seating area to the side.
Depth (15 ft): Proper positioning for launch monitors. Space for a small lounge area behind the hitting zone. Ball has time to stabilize before hitting screen.
Ceiling (10 ft): Most golfers can swing driver freely. Only unusually tall players with steep swings will have concerns.

Who this works for: Dedicated simulator rooms, two-car garages, finished basements with standard construction. This size accommodates serious practice and casual play without compromise.

Ideal Room Size: 15 x 18 x 10+ feet

At these dimensions, you're approaching commercial quality:

Width (15 ft): Comfortable seating area. Room for friends to watch. Space for additional equipment (putting green, club storage).
Depth (18 ft): Perfect launch monitor positioning. Lounging area behind hitting zone. Natural ball flight path to screen.
Ceiling (10+ ft): No restrictions for any golfer. Room for dropped ceiling elements if desired.

Who this works for: New construction with dedicated sim room, large garages, commercial installations, serious enthusiasts building dream setups.

Ceiling Height Deep Dive

Ceiling height is the single most important dimension. Here's what each height level means for your game:

8-Foot Ceilings: Challenging

Standard residential ceilings (8 feet) present real challenges:

What works:

Short irons and wedges (7i and below)
Putting practice
Chipping into nets
Some mid-irons for shorter players

What doesn't work:

Driver swings for most players
Long irons for average and tall players
Full swings for players over 5'10" with normal swing planes

Solutions:

Focus on short game practice
Modify setup (kneeling mats exist but feel awkward)
Accept the limitation and use for wedge work only
Consider raising the ceiling (expensive but sometimes possible)

Verdict: An 8-foot ceiling simulator is better than no simulator, but you're leaving significant functionality on the table.

9-Foot Ceilings: Workable

Nine-foot ceilings open up driver capability for most golfers:

The math:

Average male golfer height: 5'9" (69 inches)
Arm length: ~30 inches
Club length (driver): 45 inches
Total reach at top of backswing: ~100 inches (8'4")
Add 6+ inches clearance: 8'10" minimum

At 9 feet, a golfer of average height has roughly 2 inches of clearance with a driver. That's tight but functional for careful swings.

Who can swing freely:

Players 5'10" and under
Players with flatter swing planes
Those comfortable with slight swing modification

Who may have issues:

Taller players (6'+)
Players with steep, upright swings
Those who extend arms fully at the top

Verdict: A 9-foot ceiling works for most golfers with some awareness. Ideal for practice; acceptable for full simulation.

10-Foot Ceilings: Comfortable

Ten-foot ceilings provide clearance for the vast majority of golfers:

The math (for tall golfer):

Tall golfer height: 6'2" (74 inches)
Arm length: ~32 inches
Club length: 45 inches
Total reach: ~110 inches (9'2")
Plus clearance: ~9'8" minimum

At 10 feet, even tall players have adequate clearance. You can swing naturally without thinking about the ceiling.

Who can swing freely: Essentially everyone except unusually tall players (6'5"+) with extremely upright swings.

Verdict: 10-foot ceilings are the target for residential builds. This is where the experience feels unrestricted.

11+ Foot Ceilings: Unrestricted

At 11 feet and above, ceiling height is no longer a consideration. Professional installations typically use 12-foot ceilings for maximum flexibility and visual impact.

Room Layout Positioning

Screen Placement

The impact screen should be positioned with these considerations:

Distance from back wall: Leave 6-12 inches behind the screen for:

Screen movement on impact
Airflow (prevents moisture buildup)
Mounting flexibility

Height positioning: The screen bottom should sit 6-12 inches above the floor. This:

Accommodates hitting mat thickness
Prevents ground-strike damage
Allows for proper ball strike position

Hitting Position

The optimal hitting position depends on your launch monitor:

Overhead cameras (Uneekor, Foresight Overhead):

Position directly under the camera unit
Typically 10-13 feet from screen
Follow manufacturer's specific guidelines

Rear-mounted radar (TrackMan, Mevo+):

6-10 feet behind the ball
Ball position 10-15 feet from screen
Clear line of sight from unit to ball

Floor-level camera (SkyTrak, Bushnell Launch Pro):

Unit sits beside the hitting area
Ball typically 10-12 feet from screen
Specific positioning per manufacturer specs

Projector Placement

Projector position depends on throw ratio:

Standard throw projectors:

Mounted 12-15 feet from screen
Usually ceiling-mounted behind hitting area
Requires longer throw distance

Short-throw projectors:

Mounted 6-10 feet from screen
Common choice for residential installs
Can be ceiling or shelf mounted

Ultra-short-throw projectors:

Mounted 1-3 feet from screen
Sits below or above screen
Eliminates shadow issues
Higher cost but cleanest installation

Flooring Considerations

Concrete: The Ideal Base

Concrete provides the best foundation for a simulator:

Advantages:

Stable, level surface
Handles repeated impacts
Easy to clean
Won't shift or settle

Considerations:

Hard on feet and joints during extended sessions
Cold in winter (consider radiant heating)
May need moisture barrier in basements

Carpet Removal

Existing carpet should typically be removed:

Why remove carpet:

Launch monitors need stable surfaces
Carpet absorbs impact energy (affects feel)
Cleaning golf mat debris is easier without carpet
Moisture and odor can develop under mats on carpet

Alternative: Low-pile commercial carpet or carpet tiles can work if removal isn't possible. Avoid plush carpet.

Hitting Mat Placement

Quality hitting mats require proper subflooring:

Direct on concrete: Works well. Use a thin foam underlayment for comfort.

On plywood subfloor: Good option for uneven concrete. Use 3/4" plywood secured to concrete.

Turf flooring: Some builders install artificial turf throughout. Looks great but adds cost ($3-8/sq ft).

Mat size recommendations:

Minimum: 4' x 5' hitting surface
Recommended: 5' x 5' or larger
Ideal: Full stance area plus ball position (5' x 7'+)

Acoustic Treatment

Why Sound Matters

Golf simulators are loud. Ball impacts generate 80-100+ decibels - comparable to a lawn mower. Without treatment:

Sound transfers to adjacent rooms
Neighbors may complain (attached homes/apartments)
Echo makes the space feel harsh
Family members get disturbed

Basic Sound Reduction

For most home installations:

Impact screen selection:

Heavier screens absorb more sound
Multi-layer screens reduce noise
Avoid thin single-ply screens

Side panels:

Foam panels on walls absorb reflections
Acoustic panels (2-4" thick) reduce echo
Coverage: prioritize walls near hitting area

Ceiling treatment:

Acoustic ceiling tiles help significantly
Drop ceiling with acoustic panels is effective
Even basic foam panels reduce reverb

Advanced Soundproofing

For attached homes, apartments, or sensitive situations:

Wall isolation:

Add mass-loaded vinyl behind drywall
Double-stud walls with air gap
Green Glue between drywall layers

Floor isolation:

Floating floor systems
Rubber underlayment
Decoupling from structure

Professional assessment: If sound is critical, consult an acoustic engineer before building.

Cost Estimates for Acoustic Treatment

| Treatment Level | Materials Cost | |-----------------|---------------| | Basic (foam panels) | $200-$500 | | Moderate (panels + screen upgrade) | $500-$1,000 | | Comprehensive (full room treatment) | $1,500-$3,000 | | Professional soundproofing | $5,000-$15,000 |

Electrical Requirements

Power Needs

A complete simulator setup requires:

Typical power draw:

Projector: 200-400 watts
Computer: 300-600 watts
Launch monitor: 10-50 watts
Lighting: 100-300 watts
Climate control: 500-1,500 watts

Total: 1,100-2,850 watts typical operation

Outlet Planning

Minimum outlets:

One dedicated circuit for projector (avoids flicker)
One circuit for computer and accessories
One circuit for climate control if needed

Outlet placement:

Behind/near screen: Projector power
Near hitting area: Launch monitor, computer
General area: Lighting, accessories, fan

Recommendation: Install a small electrical panel or power distribution box to organize connections and allow easy shutdown.

Lighting Control

Proper lighting dramatically affects experience:

During play: Room should be dark or dim for projected image clarity

Options:

Dimmer switches on overhead lights
Blackout shades on windows
Separate task lighting for room use
Bias lighting behind screen (reduces eye strain)

Smart controls: Consider smart switches for easy scene setting (play mode vs. regular use).

Projector Mounting

Ceiling-mounted projectors need proper installation:

Requirements:

Secure mounting to ceiling joists (not just drywall)
Access to power (ceiling outlet or cable run)
HDMI or network cable routing
Ability to adjust position for calibration

Professional installation is recommended for ceiling-mounted projectors to ensure safety and proper alignment.

Ventilation and Climate Control

Why Ventilation Matters

Simulator rooms generate heat and can feel stuffy:

Projector adds 200-400 watts of heat
Computer adds 300+ watts of heat
Physical activity generates body heat
Enclosed spaces trap warm air

Ventilation Options

Existing HVAC:

Best option if available
May need duct extension to room
Ensure adequate return airflow

Portable AC units:

8,000-12,000 BTU for typical simulator rooms
Require window or wall exhaust
Budget: $300-$600

Mini-split systems:

Ideal for detached buildings (garages, barns)
Heating and cooling in one unit
Professional installation required
Budget: $2,000-$5,000 installed

Fans:

Ceiling fans help circulate air
Standing fans provide spot cooling
Not sufficient for poorly ventilated spaces

Temperature Considerations

Optimal range: 65-75 degrees Fahrenheit

Why it matters:

Electronics perform best in moderate temperatures
Ball performance changes in extreme cold/heat
Comfort affects practice quality

Frequently Asked Questions

Can I build a simulator in a room with support columns?

Yes, but plan carefully. The hitting area must be clear of obstructions. Columns outside the swing zone are fine. Some builds incorporate columns into enclosure design.

What if my ceiling has beams or drops?

Measure the lowest point. That's your effective ceiling height. Beams in the swing path are problematic; beams outside the hitting area are manageable.

Do I need permits for a simulator room?

Generally no permits needed for equipment installation. Electrical modifications may require permits. New construction or structural changes typically need permits. Check local regulations.

Can I convert a bedroom into a simulator room?

Yes, bedrooms often work well if ceiling height is adequate. Consider sound transmission to adjacent rooms. Flooring may need reinforcement for heavier equipment.

How do I know if my garage floor is level enough?

Use a 4-foot level in multiple directions. Small variations (1/4" over 4 feet) are fine. Significant slope can be addressed with self-leveling compound or plywood subfloor.

What's the minimum room size for a putting green addition?

Add 4-6 feet of depth beyond your hitting area for a meaningful putting surface. A 15x18 foot room can accommodate both a full simulator and a small putting area.

Can I use an existing basement with low ceiling?

Measure carefully. Standard basements (8 feet) limit full swing capability. Finished basements may have even lower effective ceilings (7'6" is common with drop ceilings). Consider wedge-only practice or partial ceiling removal.
