Database-derived shortlist
Sewing Machines With a 9-Inch Throat or Larger (Full Sourced List)
Every machine in the database with a claimed harp width of 9″ or more — 21 machines from 10″ domestics to 21″ longarms — plus the famous “9-inch” machines that actually publish less.
“9 inches of throat” is the line quilting marketers love — several famous “9-inch” machines actually publish 8.5–8.8″. The list below applies the threshold literally to claimed widths in the database; the borderline cases get their own section so you can judge the rounding yourself.

Beloved machines that miss the literal cut — by 0.2–0.5″ that you will likely never feel:
Janome 1600P-QC
8.8″ × 5.5″ harpJanome publishes the workspace as W 8.8″ × H 5.5″ and markets it as ‘nearly 9″ × 6″ to the right of the needle’ — a good example of marketing rounding.
Janome HD9 Professional
8.8″ × 5.5″ harpJanome markets ‘nearly 9″ × 6″ to the right of the needle’; the spec-sheet figure distributed by dealers is 8.8″ × 5.5″. Bed area 12.25″ × 7″.
Brother PQ1600S
8.7″ × 5.7″ harpBrother publishes a 5.7″ × 8.7″ needle-to-arm space — fractionally wider on paper than the PQ1500SL it replaces.
Brother PQ1500SL
8.6″ × 5.7″ harpBrother publishes the workspace as 5.7″ × 8.6″ (height × width). Community measurements have reported up to ~8.75″ to the body — unverified.
Juki TL-2000Qi
8.5″ × 5.9″ harpJuki's US spec page does not publish throat dimensions; 8.5″ × 5.9″ is the figure published by major Juki retailers. Some dealers market the TL line as a ‘9-inch arm’ — measure before you rely on it.
Juki TL-2010Q
8.5″ × 5.9″ harpJuki's own US page publishes machine dimensions only (17.75″W × 9″H × 8.5″D). 8.5″ × 5.9″ is the retailer-published throat figure; some dealers advertise a ‘9-inch arm’. Juki Australia lists the near-identical TL-2200QVP Mini at 203 × 112 mm (8″ × 4.4″) — a textbook example of why claimed numbers need measuring.
Bernina 570 QE
8.5″ × n/p harpThe new-generation 570 QE has an 8.5″ throat (older generation was 7.5″ — check which one you're buying used).
FAQ
Which sewing machines have 9 inches of throat space or more?
In this database, 21 machines have a claimed harp width of 9″ or more — from 10″ domestics (Janome MC6650/MC6700P, Bernina 770 QE PLUS, Pfaff QE 720) through 11–13.5″ quilting flagships (Brother BQ3100, Baby Lock Jazz II, Janome Continental M7) up to 15–21″ sit-down and frame longarms.
Is the Juki TL-2010Q a 9-inch throat machine?
Not quite, despite the marketing: retailers publish 8.5″ × 5.9″, and some dealers round it up to a “9-inch arm.” The same applies to the Janome 1600P-QC/HD9 at a published 8.8″. They are excellent machines — they are just not 9-inch machines on paper.
How much throat space do I need to quilt a king-size quilt?
There is no hard rule, but the working consensus: 9–11″ makes queens comfortable and kings possible; 15″+ (sit-down longarm) makes kings comfortable. Below 9″, king-size free-motion is an exercise in quilt-wrestling — doable, not fun.
This is not a listicle. Every machine above comes from the same harp-space database, every number has a source link on the machine's page, and machines the criteria exclude are excluded — even popular ones. Prices move; verify before buying.
