Standard rug sizes are 4×6, 5×8, 6×9, 8×10, 9×12, 10×14, and 12×15. If you’re between sizes, always go larger — a rug that’s too small makes a room feel disjointed. Use painter’s tape on the floor to mock up the size before you buy.

Frequently Asked Questions

What size rug should I get for my living room?

As a general rule, all furniture legs should sit on the rug, or at minimum the front legs of each piece. Leave 12-18 inches of bare floor visible between the rug edge and the walls.

How do I size a rug for under a dining table?

Add at least 24 inches beyond the table's edge on all sides so chairs stay on the rug even when pulled out.

Should a rug go under the bed or just at the sides?

Either works: a rug large enough to extend past the sides and foot of the bed creates a full grounded look, while smaller runners on either side are a lower-cost alternative.

What's the difference between an area rug and a runner?

An area rug is typically wider and used to anchor a seating or dining area, while a runner is a long, narrow rug used in hallways, entryways, or alongside a bed.

How much space should be left between the rug and the wall?

Most designers recommend 12-18 inches of exposed floor between the rug's edge and the wall in a standard room, though larger rooms can handle more.
