8x10 vs 9x12 rug

A 9 × 12 is a foot wider and two feet longer than an 8 × 10, with 35% more area: 108 sq ft against 80. With the typical 18 in of floor showing on every side, an 8 × 10 needs a room of about 11 × 13 ft and a 9 × 12 about 12 × 15 ft.^{[1 · Oct 29, 2026]}

Floor left showing

Our arithmetic: floor left at each end and along each side, with the rug's long side along the room's long side. Bed Bath & Beyond suggests about 18 in in a standard room and 8 in in a small one.^{[1 · Oct 29, 2026]}

Room	8 × 10 (ends / sides)	9 × 12 (ends / sides)
10 × 12 ft	1 ft / 1 ft	0 in / 6 in
11 × 13 ft	1 ft 6 in / 1 ft 6 in	6 in / 1 ft
11 × 14 ft	2 ft / 1 ft 6 in	1 ft / 1 ft
12 × 14 ft	2 ft / 2 ft	1 ft / 1 ft 6 in
12 × 15 ft	2 ft 6 in / 2 ft	1 ft 6 in / 1 ft 6 in
13 × 16 ft	3 ft / 2 ft 6 in	2 ft / 2 ft
14 × 16 ft	3 ft / 3 ft	2 ft / 2 ft 6 in

If the 9 × 12 leaves less than about 8 in, it will look crowded; if the 8 × 10 leaves more than about 2 ft, furniture may float off it. For a dining table, work from the table instead: see dining room rug size.
