You need a lot more room than you think! You need to be able to walk around the machine, front, back and, depending on the frame, one or both sides. I have about 2' on 3 sides and that seems to work. I can still get access to one side to get to the rollers. Casters are available for some machines, but if you get a stitch regulator or computer, you will need to be mindful of keeping the frame level every time you move it.
