The four tiers, by what fits under the arm
Domestic machines - 6 to 10 inches wide, 4 to 5 inches high
Everything from an entry Brother to the Janome Memory Craft 6700 Professional. Janome publishes the 6700P’s workspace as 255 x 120 mm - 10.04 in wide by 4.72 in high. That is the widest domestic here, and it also has the lowest opening of any machine on this page, which is the trade nobody mentions.
Straight-stitch semi-professionals - 8.5 to 8.7 inches wide, 5.7 to 6 inches high
The Juki TL-2010Q and TL-2000Qi, and the Brother PQ1600S and PQ1500SL. They do exactly one stitch, at 1,500 stitches per minute, with a knee lifter and a big table. Juki publishes its arm as 215 mm wide by 150 mm high. That is 51 square inches of opening - more than the 10-inch Janome, despite being an inch and a half narrower.
Sit-down quilting machines
The tier above the semi-pros, where the machine head is set into a large table and you move the quilt rather than the needle. Buying options here are thinner than the marketing suggests, and the honest overlap with the straight-stitch tier is larger than either camp admits.
True longarms - 15 to 26 inches, on a frame
Handi Quilter, Gammill, APQS, Innova, Bernina Q-series, Baby Lock longarms. A Handi Quilter Amara 20 lists at 12,995 US dollars at an authorized dealer with 20 inches of throat and 2,500 stitches per minute. It is not on Amazon. None of them are.
Why we do not have a buy button for the longarm tier
We checked, on 1 September 2026, and every retail result for those brands was an authorized dealer storefront. There is no Amazon listing to link, so there is no buy button on this site for a longarm and there will not be one.
A lot of sites in this niche put a “check price” button on a longarm anyway, pointed at a search results page that cannot contain the machine. We would rather tell you it is a dealer purchase and show you what the tier actually costs and what to ask the dealer.
Width is the number that gets quoted. Height is the number that decides
Manufacturers quote throat width because it is the bigger number. A rolled quilt is a cylinder, and a cylinder is constrained by the smaller dimension of the opening it has to pass through. Multiply the two:
- Juki TL-2010Q: 8.5 x 6 = 51.0 sq in
- Brother PQ1600S: 8.7 x 5.7 = 49.6 sq in
- Janome MC6700P: 10.04 x 4.72 = 47.4 sq in
The 10-inch machine has the smallest opening of the three. If you shopped on the advertised width alone you would have bought it. The full working, for every machine on this site, is in the normalized throat space chart.
What to buy, briefly
If you already own a domestic machine and you are fighting a queen quilt, the straight-stitch tier is the upgrade with the best return: it roughly doubles your usable opening for a fraction of a longarm, and it will still piece. If you need decorative stitches and buttonholes on the same machine, the Janome MC6700P is the widest thing that does everything - just go in knowing you are trading height for width.
If you quilt for other people and the volume is real, the frame tier is the answer and you will be buying it from a dealer. That is not a failure of this site; it is how the category is distributed.
