it depends on what length you have your frame set up... some are adjustable. i think the big ones are 12' and you need room to get around one of the ends. I have limited space, so I set my Hinterberg stretch up with 9-1/2' poles. that left me is 1.5' to get past the end in the room I had. with this set up, i can quilt queen sized quilts, but not those that go to the floor, just the mattress depth on the sides. however, i did manage, with some finagling, to quilt a king sized quilt.
