If your room dimensions are wrong, every purchase after that gets harder. Start here.

## Practical dimension ranges
| Dimension | Minimum that can work | More comfortable target | Why it matters |
|—|—|—|—|
| Ceiling height | ~9 ft for some golfers | ~10 ft+ for more golfers | Swing freedom and confidence |
| Width | ~10 ft (single sided) | ~12–15 ft (more flexibility) | Safe swing arc + handedness flexibility |
| Depth | ~12–15 ft (tight depending on setup) | ~16–18+ ft | Monitor placement + ball flight + safety buffer |

## How to measure correctly
– Measure clear dimensions at hitting area, not just room center.
– Include mat/platform height in clearance checks.
– Simulate stance and full follow-through with your longest club.

## FAQ
### What’s the single biggest dimension mistake?
Ignoring mat height and finding out too late your ceiling is effectively lower than expected.

### Do I need centered hitting?
Not always. Offset hitting can work in narrower rooms, depending on monitor and enclosure choices.

### How much does monitor type change depth needs?
A lot. Radar systems often need more depth than many camera-based systems.
