Rug Size Guide for Bedrooms

The rug should extend at least 18-24 inches beyond the sides and foot of the bed, so your feet land on it getting out of bed from any side. For a queen bed, that means an 8x10 rug at minimum.

For a bedroom, size the rug so it extends at least 18-24 inches beyond the sides and foot of the bed — that’s the distance that puts your feet on rug, not bare floor, when you get out of bed from either side. For a queen bed, that works out to an 8x10 rug at minimum; a king bed typically wants a 9x12.

Size by bed, not by room

Unlike a living room, where you size to the furniture footprint, a bedroom rug is sized almost entirely around the bed itself — the goal is consistent floor coverage on the sides and foot you actually walk on.

Bed size Recommended rug size Typical coverage past bed edges
Twin 5x7 18-24 in on the open sides
Full / Double 6x9 or 8x10 18-24 in
Queen 8x10 18-24 in
King 9x12 24-30 in

Two layout options

  • Full coverage: one rug large enough that the head of the bed (and often the nightstands) sits on top of it, with the rug extending past the sides and foot. This is the sizing shown in the table above, and it’s the simpler option if you’d rather not coordinate multiple pieces.
  • Runners on each side: instead of one large rug under the bed, place a runner (roughly 2.5x7 to 2.5x8) along each side of the bed where your feet land getting up. This uses less total rug and can be a better fit for a smaller bedroom or a bed frame you don’t want covered. A short runner or small rug at the foot of the bed is a common addition to this layout.

Centering the rug

Center the rug on the bed’s width, not the room’s width, if the two don’t align — the bed is what you’re walking around, and an off-center rug relative to the bed will look wrong even if it’s perfectly centered on the walls.

What to measure before you shop

Measure your bed’s actual footprint (mattress plus any frame overhang) rather than assuming standard dimensions, since bed frames vary in how far they extend past the mattress. Add your target coverage (18-24” for most sizes, 24-30” for king) to each open side to get your minimum rug dimensions, then round up to the nearest standard rug size.

Frequently Asked Questions

What size rug do you need for a king bed?

9x12 is the standard recommendation for a king bed, extending roughly 24-30 inches past each side and the foot of the bed. An 8x10 can work in a smaller primary bedroom, but the margins will be tighter, especially at the sides.

What size rug do you need for a queen bed?

8x10 is the standard size for a queen bed, giving about 18-24 inches of coverage past the sides and foot. A 9x12 also works well if the room has the floor space and you want a more generous border.

What size rug do you need for a full or double bed?

6x9 or 8x10 both work for a full/double bed, depending on room size. 6x9 keeps a tighter, more proportional look in a smaller bedroom, while 8x10 gives a more generous border if the room is larger.

What size rug do you need for a twin bed?

5x7 is the standard size for a single twin bed, such as in a kids' room or guest room. For a room with two twin beds, either use two 3x5 runners (one at the side of each bed) or one larger rug (6x9 or 8x10) that spans under and between both beds.

What size rug goes under a king bed specifically, versus just in front of it?

A full-coverage rug under a king bed (extending past all three exposed sides) is typically 9x12. If you'd rather not put a rug under the bed itself, two runners (roughly 2.5x7 to 2.5x8) placed on each side of the bed, plus optionally a small rug or bench-width runner at the foot, is a common alternative that uses less rug.

Should a bedroom rug go all the way under the bed, or just show around the edges?

Either is fine — most bedroom rugs are large enough that the head of the bed (and often the nightstands) sit on top of the rug, with the visible portion showing at the sides and foot. The rug doesn't need to be visible from under the entire bed; what matters is how much shows around the exposed edges.
