Room dimensions are the first constraint to understand when planning a golf simulator. Your space determines which launch monitors will work, whether you can use a projector or need a TV, and whether you'll have full swing capability or be limited to shorter clubs. Many golfers discover these constraints after purchasing equipment—an expensive mistake. Width affects swing clearance. Depth determines launch monitor compatibility. Ceiling height limits club selection and display options. Before shopping for any component, know your exact measurements and understand how each dimension affects your options. The Room Fit tool can check your specific situation, but this guide explains the underlying logic so you can make informed tradeoffs.
If You Only Remember 3 Things
- Ceiling height is the most common limiting factor — Below 9 feet restricts full driver swings; below 8.5 feet may require foam balls
- Depth determines launch monitor type — Radar systems work at 12'+ depth; camera-based systems need 15'+
- Width affects comfort more than function — 10' minimum works, 12' is comfortable, 14'+ allows both-handed play
Width Requirements
Minimum 10' for compact builds, 12' recommended for comfort, 14'+ for both-handed use. Width affects swing clearance and equipment placement.
For right-handed golfers in tight spaces, you can get away with 10' minimum. Left-handed setups or ambidextrous use requires additional width for proper equipment orientation.
What width provides:
- 10': Tight but functional for single-handed play
- 12': Comfortable clearance with equipment mounted
- 14'+: Room for both left and right-handed golfers
Depth Requirements
Minimum 12' for radar systems, 15'+ for photometric systems. Depth determines which launch monitors will work reliably.
Radar-based systems work well in shallow rooms because they track the ball immediately after impact. Camera-based (photometric) systems need more distance to capture the full ball flight and club movement.
Depth and launch monitor compatibility:
- 12–14': Radar launch monitors only
- 15–17': Most camera-based systems work
- 18'+: All systems work comfortably
Ceiling Height
Minimum 8.5' for limited swings, 9'+ for full swings. Taller golfers need more clearance. Consider using foam balls in lower ceilings.
If your ceiling is below 9 feet, you may need to:
- Restrict your swing to three-quarter shots
- Use foam practice balls instead of real golf balls
- Focus on short game and putting practice
Height and display compatibility:
- Below 9': TV display recommended
- 9'+: Short-throw projector possible
- 10'+: Standard projector setups work well
Decision Checklist
Before finalizing your space:
- [ ] Measure width at hitting position (wall to wall minus obstructions)
- [ ] Measure depth from hitting mat to back wall
- [ ] Measure ceiling height at lowest point (check for beams, fixtures)
- [ ] Account for planned flooring changes
- [ ] Identify any obstacles (doors, windows, HVAC vents)
- [ ] Run exact dimensions through Room Fit tool
Common Mistakes
Mistake: Measuring ceiling height before flooring installation Why it matters: Adding carpet, pad, or platform can reduce effective height by 1–2 inches How to avoid: Measure after flooring is complete, or subtract planned flooring thickness
Mistake: Ignoring door swing clearance Why it matters: A door that opens into your hitting area creates a safety hazard How to avoid: Map your full swing arc and ensure no interference from doors or furniture
Mistake: Assuming "close enough" on dimensions Why it matters: 11'6" depth is significantly different from 12' for radar systems How to avoid: Measure precisely; use feet and inches, not approximations
Working Within Tight Spaces
If your room is at or near minimum dimensions:
- Prioritize radar-based launch monitors (less depth required)
- Consider TV displays instead of projectors (lower ceiling requirements)
- Use compact hitting mats and minimal enclosure systems
- Accept that full driver swings may not be possible
Advanced: Maximizing Difficult Spaces
Garage conversions: Garages typically offer good width (16–20') but may have ceiling height challenges (8–9'). Two-car garages provide excellent depth (20–24'). Consider whether the garage door will remain functional.
Basement installations: Basements often have ceiling obstructions (ducts, pipes, beams). Map the lowest point across your entire swing arc, not just at the hitting position. Support columns can affect width calculations.
Multi-purpose rooms: If the space serves other functions, plan for equipment that can be stored or moved. TV-based setups are generally easier to integrate than projector systems.
Measuring tips:
- Use a laser measure for accuracy
- Measure at multiple points (rooms aren't always square)
- Check ceiling height at several locations
- Document everything with photos
When to compromise: If your space is borderline, prioritize function over immersion. A working simulator in a tight space beats a non-functional premium setup.
How This Affects Your Build
Use our Room Fit tool to check if your specific dimensions support the build archetype you're considering. These minimum requirements are based on typical setups—individual products may have different needs. Always verify component-specific requirements before purchasing.
