Why ceiling height is the make-or-break number
Most people assume floor space is the constraint. It isn't — ceiling height is. A driver swing needs serious overhead clearance, and the lowest obstruction in the room (a light, a beam, the garage-door rail) decides whether you can swing freely. That's the first thing this calculator checks.
The second decision is which launch monitor to buy. In low or tight rooms, a floor / behind-the-ball unit (no ceiling mount) is almost always the right call. In a comfortable room you can choose either. The calculator tells you which path fits.
Golf simulator space — quick answers
- What ceiling height do you need?
- 9–10 ft is comfortable for a full swing with driver; 8.5 ft is the practical minimum; under ~8 ft you're into irons / short-game / data only.
- Will it fit in a two-car garage?
- Usually yes — garages tend to give 18–20 ft width, ~20 ft depth and 9–10 ft ceilings. Measure to the lowest obstruction.
- Low ceiling — am I stuck?
- No. Floor-based launch monitor + tee toward the back wall + irons focus gets you full data and simulated rounds. See our low-ceiling picks.
- How much depth?
- 16–18 ft is comfortable; 12–15 ft works with a short-throw projector and ~8 ft ball-to-screen.
