Quick answer

Rug rule of thumb: Living room — extend at least under front sofa legs (8×10 ft for most). Bedroom — extend 24" past bed sides and foot (9×12 ft for king). Dining — extend 24" past table edges so chair legs stay on rug.

How rug size is determined

Rug sizing follows three simple rules per room type — applied to the largest piece of furniture, not the room. Room dimensions only matter as a maximum boundary (leave 12–18 inches of bare floor as a border).

Living room rules

All-on rug: Every furniture leg sits on the rug — most luxurious look. Needs 9×12 or larger.
Front-legs-on rug: Front legs of sofa and accent chairs on rug, back legs off — most common. 8×10 works.
Floating rug: Rug only under coffee table — works only in tiny spaces, looks cheap if room is large.

Bedroom rules

Rug should extend at least 24 inches past the bed on the sides and foot.
Bedside tables either sit on the rug or just off it (both work).
Two runners on each side of the bed is an alternative for tight rooms.

Dining room rules

Rug should extend 24–30 inches past the table on every side so chair legs stay on the rug when pulled out.
Round table = round rug or square rug at least table diameter + 48 inches.

Frequently asked questions

What size rug for a king bed?

For a king bed (78×72 inches), use a 9×12 ft rug positioned to extend at least 24 inches past the sides and foot of the bed. An 8×10 ft works for tighter spaces; 10×14 ft for grand bedrooms.

What size rug for a queen bed?

For a queen bed (78×60 inches), use an 8×10 ft rug — extends about 24 inches past the sides and foot. A 6×9 ft works at the foot of the bed only (without going under).

What size rug for a 12x15 living room?

For a 12×15 ft living room, an 8×10 ft rug fits the front-legs-on-rug rule. For a more grounded look use a 9×12 ft so all sofa, accent chair and coffee table legs sit on the rug.

What size rug for a 6-seater dining table?

For a 6-seater dining table (about 36×72 inches), use a 9×12 ft rug — extends 30 inches on every side so chairs stay on the rug when pulled out.

Can a rug be too big?

Yes — leave at least 12–18 inches of bare floor between the rug and the walls. A wall-to-wall rug looks like carpet. The bare-floor border is what defines the rug as a rug.
