Mine is 14 by 21. Everything is mobile – so I could clear the center of the room to build the 12 foot dining table. Also I can open the garage door. But I really really miss having a ~4 by 6 or so Assembly table rather than building on top of the unisaw.
You inevitably get stuff stacked then need to make a cut.
