Golf Simulator Room-Fit Calculator
Updated 2026-11-12 · Runs in your browser; nothing is sent anywhere · Built from published maker figures
Enter your room and the calculator checks your ceiling, width and depth, which launch monitors fit, the largest standard enclosures that fit, where a projector would sit, and full builds for your budget. It's a planning tool, not an install drawing, so always swing-test in the room.
Assumptions, shown in full
Usable ceiling = your lowest point minus mat thickness. Compared with The Indoor Golf Shop's table: under 5'10" flat swing 9 ft min / 10 ft rec; under 5'10" upright 9.5 / 10+; 5'10"–6'2" 10 / 10–11; over 6'2" 10.5 / 11+ (SIG). Under 9 ft we use Carl's Place's "limited swings" band, and under 8 ft we don't recommend full swings (Carl's).
Width: under 10 ft = too narrow; 10–14 ft = offset tee; 14 ft+ = centered tee for both handedness (Carl's).
Enclosure fit: frame width + 6 in and frame height + 3 in must fit (Carl's buffers: 4–6 in width, 2–3 in height) (Carl's). Frame sizes: SIG (SIG table), Carl's DIY (spec sheet), PlayBetter SimStudio (PlayBetter).
Depth, planning minimum = 12 in screen gap + ball-to-screen (the maker's minimum; 10 ft if none is published) + behind-ball space (the unit's setback for behind-the-ball radars; otherwise 4 ft). Comfortable = 12 in + 10–12 ft + 7 ft (or the unit's recommended setback). The gap and swing-space figures come from Carl's and SIG; unit distances from each maker (see the comparison). Bushnell's own 13 ft minimum depth is also applied.
Ceiling-mount units must fall within the maker's mounting range; above it they hang on a drop pole (SIG).
Projector distance = throw ratio x projected width, with the image filling the screen height (SIG method). "Behind the golfer" means at least 24 in behind the ball, the same working assumption The Indoor Golf Shop uses. The calculator assumes a ball-to-screen distance of room depth minus 1 ft gap minus 7 ft, kept between 8 and 12 ft.
