I have a 12' table with a Nolting head. I lose about 10 inches at each end. You always need extra on each side just to load the quilt so you have an extra 2 or 3 inches to load that you won't sew on unless you are testing after a bobbin change. Ask me why I do that.
I did load and quilt a 110 x 126 on mine. I loaded it with the 110 across and the 126 as the length. There was a little bit of extra room, but not much. If I was buying a new table right now, I would buy a 12 or 14 foot, although I don't have that many more king size quilts in my future. I only quilt for me, so I can make sure I stay within the boundary of my table. Of course, you can always do a QAYG of parts of it and sew it together afterwards. Not something I have tried and don't want to.
Edited to add: What is just as important to me is the throat of the machine. Mine is a 24 and will only let me use about a 14" panto on my frame. If you are going computerized, you may want to check out how big of a design you can sew without rolling the quilt. That saves more time than you realize, because each time you have to get everything lined up again. I can tell you from experience, that you do get better at rolling and relining up the quilt.
