Direct answer
A comfortable planning target is roughly 10 feet high, 14 feet wide, and 18 feet deep, but those are not universal minimums. The tallest user's full driver swing and the selected launch monitor determine the real requirement. Carl's Place notes that narrower rooms can sometimes work with an offset hitting position, while right- and left-handed play generally needs more width. Screen buffer, tee distance, projector throw, and safe ball containment also consume depth.
Test full swings with the longest club before committing. Include ceiling fans, garage tracks, openers, soffits, doors, lights, and storage in the measurement. Then verify the exact enclosure and launch-monitor drawings. See Carl's room-measurement guide.
