How much room is that, really?
The Janome HD9 Professional's claimed 8.8″ harp width is wider than 7 of the 30 machines with published widths in this database (median: 11.3″). Within its class — high-speed straight stitch — the average published width is 8.5″.
Height matters as much as width when half a quilt is rolled in the harp: at 5.5″ of claimed vertical space, a rolled queen is workable with good basting and a pool-noodle roll.
Spec note: Janome 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″.
