Start with as large as you can go now. You can always get a smaller table for whatever machine you get. And, as has been mentioned some tables can be made smaller.

When you were learning your long did you buy books, DVD's or take classes. I have taken some classes. After I get my long arm I will have to take my time and as for the classes they add up. But You Tube is great also. I'm nervous and
excited at the same time.

I could only fit 10 foot 8 inches in my workroom so I had a 12 foot table cut down. I can quilt quilts up to 110" wide.

I've been in business since 2005 and have quilted hundreds of quilts for hundreds of clients. In all those years, I've had to turn down only TWO quilts because my frame couldn't accommodate their width.

I'd opt for the 12' table. Remember that even though the rails on a ten footer are 120 inches long, you won't be able to quilt a quilt with a back larger than about 106 to 108 inches. You are never able to quilt the full length of the rails, because of the width of the machine. So the biggest quilt top that you can do will be about 100 inches wide, since the top has to be a few inches smaller than the backing to be longarm quilted.
My humble opinion is to get the longest table your quilting room can accomodate.

Go for the largest table you can fit in your home, but remember that you will need to get around it to the back, so you will need some addtional space around the sides.

i would get the 12 and where ever i would live would just have to work around my frame.

actually every home i have ever purchased was done with quilting and my cats happiness in mind.

if the house didn't suit the way i live my life i didn't buy it.
