What size rug under a dining table?

Add about 4 feet to the table length and width — 24 inches on each side.

What size rug for a queen bed?

An 8×10 placed under the bottom two-thirds of the bed works well.

A too-small rug makes the room feel disjointed. When in doubt, go bigger.

Either all legs on or just front legs on both look good — just keep it consistent.

Aim for 12–18 inches of bare floor between the rug and the walls.

Living room & bedroom: leave about 18 inches of floor around the rug for an all-legs-on layout, or about 3 feet for a front-legs-on layout. We pick the largest standard size that fits.
Dining room: the rug should extend about 24 inches past every table edge so pulled-out chairs stay on it. We pick the smallest standard size that does.

Standard sizes: 3×5, 4×6, 5×7, 5×8, 6×9, 8×10, 9×12, 10×14, 12×15 ft.

A 14 × 12 ft living room, all legs on: 14 − 3 = 11 ft and 12 − 3 = 9 ft available → 9 × 12 is too long, so 8 × 10 is the best fit.

Most living rooms suit an 8×10 or 9×12 rug, leaving 12–18 inches of floor around the edges.
