Garage Golf Simulator Build: A Full Parts List for One Bay

More home golf simulators end up in garages than anywhere else, and for a simple reason: the garage is usually the only room in the house with enough depth to swing a driver and take a full ball flight reading. A standard single bay, roughly 10 to 12 feet wide and about 20 feet deep, is a genuinely good simulator space that most owners underrate. This guide turns one bay into a complete, buyable package: a full parts list, plus the three problems a garage adds that a spare bedroom never would.

What a garage bay gets right

A garage bay's depth is its superpower: at about 20 feet deep, a single bay gives you roughly 19 feet of usable depth, which clears the minimum depth requirement of every launch monitor we sell for simulator use. Usable depth is room depth minus 1 foot, because the screen needs standoff from the wall. Nineteen feet clears the Full Swing KIT's 18-foot requirement, the deepest in our lineup, and comfortably clears the 16 feet that behind-ball hybrid (radar plus camera) units like the FlightScope Mevo Gen2 and overhead units like the Uneekor EYE XO demand.

Compare that to the typical spare room, where 12 feet of depth restricts you to beside-ball monitors, and the garage's appeal is obvious. In a garage, the depth check stops filtering your options and you choose tracking technology on merit. Width is the quieter limit: an 11-foot-wide bay allows a screen up to 10 feet wide (maximum screen width is room width minus 1 foot), which is plenty, but it means the enclosure should be matched to your measured width from the sizes offered, not to a wish. A two-car garage relaxes the width limit and changes nothing else in this article; the parts list below works in either.

The three problems a garage adds to a simulator build

A garage adds three problems a spare bedroom never poses: door hardware that lowers the real ceiling, ambient light that washes out the image, and a concrete floor that punishes joints and equipment.

Ceiling height and what hangs from it

Measure your garage ceiling to the lowest obstruction, not to the drywall, because the door tracks, the opener, and the lighting are the real ceiling. Many garages run 8 to 9 feet nominal, and then the door hardware takes a bite out of the middle of the room, often exactly where you want to swing. Before buying anything, stand where the mat will go and take a full-speed driver swing. If the club or your hands threaten the opener rail, shift the hitting position deeper into the bay; with…
