Sewing machines with 12 inches of throat space
The honest answer is that domestic machines stop at about 10 inches of width, and the machines that reach 12 and beyond are a different category with a frame attached.

The short answer
No domestic machine on this site publishes 12 inches of throat. The widest publishes 10.04.
That is the Janome Memory Craft 6700 Professional, at 255 mm - 10.04 inches - to the right of the needle. It is also the machine with the smallest actual opening here, because its published height is 120 mm (4.72 in).
Twelve inches and beyond is frame-machine territory: 15 to 26 inches of throat, mounted on rails, sold through authorized dealers.
Why this page exists
“Sewing machines with 12 inch throat space” is a real search, and the honest answer is that the thing being searched for does not exist as a domestic machine. Most pages that rank for it either quietly change the subject to 9-inch machines, or list frame machines without mentioning that they need a frame and a dealer.
We would rather tell you where the ceiling actually is and what your options are on either side of it.
Where the domestic ceiling sits, precisely
| Machine | Published width | Published height | Opening |
|---|---|---|---|
| Janome MC6700P | 10.04 in (255 mm) | 4.72 in (120 mm) | 47.4 sq in |
| bernette 79 | 9 in (230 mm) | Not published | Cannot be calculated |
| Brother PQ1600S | 8.7 in | 5.7 in | 49.6 sq in |
| Juki TL-2010Q | 8.5 in (215 mm) | 6.0 in (150 mm) | 51.0 sq in |
| Handi Quilter Amara 20 (frame) | 20 in (dealer-published) | Not published in the source we could read | Not applicable - the quilt is not rolled |
There is a gap between 10 inches and the frame tier, and nothing on this site fills it. That is a fact about the market rather than a gap in our research.
What 12 inches would actually buy, if it existed
Suppose a domestic machine published 12 in of width at the Juki’s 6 in of height. That is 72 square inches, against the Juki’s 51 - a 41% larger opening.
Useful, and not transformative, because the binding dimension would still be 6 inches of height. Half a king quilt rolled still would not clear it.
That is the real reason the domestic ceiling is where it is: past a point, adding width stops solving the problem. The problem is solved by not rolling the quilt at all, which is what a frame does.
What actually reaches 12 inches and beyond
Frame longarms. An authorized dealer lists the Handi Quilter Amara 20 at 20 inches of throat with stitching speeds up to 2,500 stitches per minute, priced at 12,995 US dollars on 1 September 2026.
These are not bigger domestic machines. The quilt is stretched flat between rollers and the machine head is pushed along rails over it. Nothing is rolled, so the throat opening comparison stops applying entirely.
They are also not available online - every retail result for Handi Quilter, Gammill, APQS, Innova, Bernina Q-series and Baby Lock longarms that we checked was an authorized dealer storefront. There is no buy link on this site for any of them, and here is the honest cost picture instead.
Skip this
If you searched for 12 inches because a queen quilt is a fight, buy height instead
The fight is almost always vertical. Half a queen rolled runs out of throat height before it runs out of width, and the fix is 6 inches of height rather than 12 inches of width.
The Juki TL series publishes exactly that - 150 mm - at 1,500 stitches per minute, for a small fraction of a frame machine and with no room required. That is the honest recommendation for most people who arrive on this page.
The other thing worth knowing
Longarm throat figures and domestic throat figures are not directly comparable, even though both are quoted in inches. A domestic machine’s throat is a tunnel a rolled quilt has to squeeze through; a longarm’s throat is how much flat quilt is reachable before you advance the roller.
So 20 inches on a frame is not “twice as good” as 10 inches on a table. It is a different measurement of a different problem, and the honest way to compare them is on the domestic versus longarm page.
The picks
The closest domestic machines actually get
One has the widest published throat here at 10.04 in; the other has the largest actual opening at 51 sq in. Neither is 12 inches, and we are not going to imply otherwise.
Juki
Juki TL-2010Q
Semi-professional straight-stitch tier
8.5 in wide by 6 in high of arm space, straight stitch only, at 1,500 stitches per minute. Six inches of usable height is the number to notice: it is the most vertical room of any domestic machine in this comparison, and height is what a rolled quilt actually consumes.
Skip it if: You need decorative stitches or a buttonhole. This machine does one stitch, in one direction, extremely well, and nothing else at all.

Janome
Janome Memory Craft 6700 Professional
Upper domestic tier
10 inches to the right of the needle and 200 built-in stitches: the widest machine here that still does everything a domestic machine does. The catch is 120 mm of height, the lowest opening in this comparison.
Skip it if: Your bottleneck is a king-size quilt rolled under the arm. Extra width does not help if the roll will not clear 4.7 in of height.

How this was ranked
Machines we claim to have tested: none. Everyone in this category says they tested twenty. We have not tested any, and we say so. What we did instead: built the candidate set from what Amazon actually stocks, read the published specification off each manufacturer’s own page, normalized every measurement into the same units and the same order, did the arithmetic on what each step up buys, and left every figure the maker does not publish visibly blank rather than filling it in. Every number on this page links to where it was published, so you can check the work in about five minutes.

Questions people actually ask
Frequently asked
Are there sewing machines with 12 inches of throat space?
Not among domestic machines on this site - the widest publishes 10.04 inches. 12 inches and beyond is frame longarm territory, typically 15 to 26 inches, sold through authorized dealers rather than online.
What is the largest throat on a domestic sewing machine?
By published width, the Janome MC6700P at 10.04 in (255 mm). By actual opening, the Juki TL series at 51 square inches, because their published height of 6 in beats the Janome’s 4.72 in.
Would 12 inches of throat let me quilt a king-size quilt?
Probably not on a domestic machine, because the binding dimension is height rather than width. Half a king rolled does not clear 6 inches of height, and adding width does not change that. A frame, where the quilt is never rolled, does.
Is a 12-inch longarm the same as a 12-inch domestic machine?
No, and the numbers are not comparable. A domestic throat is a tunnel a rolled quilt squeezes through; a longarm throat is how much flat quilt is reachable before you advance the roller. Different measurement, different problem.
What should I buy if I wanted 12 inches?
Height rather than width. The Juki TL series publishes 6 inches of throat height at 1,500 stitches per minute, which is the dimension that actually stops a rolled queen quilt, and it needs no frame and no dealer.
