8 feet wide would only give you 96 inches tops. My gammill , when pushed all the way to one end, takes up about 20 inches. I need to be able to see into the bobbin area to clean, oil and troubleshoot. Add on the extra backing and batting you need on each side of your loaded top (you put a clamp or something on each side to keep the backing taut while you quilt), and now you are way over 8 feet. Queen quilts run about 88 inches (give or take). Hope this helps!
