The 10' requirement is not the simulator itself. when the average 6' person swigs a driver, The clubhead is 9'8" high. That being said, We installed on where the finished ceiling was 9'10" so we cut the simulator frame down 2" so it will fit in the space. It did not mess with the sensors so it is still 100% accurate. Its a goof thing they are a short family! The tallest person is 5'7" so it works for them If anyone taller comes in they are instructed by the homeowner to "be careful"
