Bedroom Rug Size Calculator: What Size Rug Under a Bed?

Pick your bed size — Twin to California King — and get the right bedroom rug size for a roomy, standard, or compact look, in feet and cm, with placement tips for each.

Getting your bedroom rug size right is easiest when you can see it. This interactive simulator draws your room to scale: enter your room size, pick your bed and where it sits against the top wall, and choose how much of the bed the rug should cover. It sizes the rug to reach about 60 cm (24 in) beyond the bed on each exposed side and the foot, trimming at any wall.

The Rule for Each Rug Coverage

In every case the rug reaches about 60 cm (24 in) beyond the bed on each exposed side and at the foot — cut off wherever a wall gets in the way. What changes between the three options is how far up the bed the rug starts.

Roomy — the whole bed on the rug

The rug starts at the head of the bed and covers the entire bed, with the nightstands sitting on it too. It’s the most luxurious option — you step onto softness everywhere around the bed — and it suits larger bedrooms where the rug has room to breathe.

Standard — under the lower two-thirds

The most common and economical choice. The rug starts about one-third of the way down the bed (just below the nightstands, so they stay off the rug) and covers the lower two-thirds. You still get a soft landing where you step out of bed, using less rug.

Compact — under the lower third

The rug sits under just the lower third of the bed — the foot area — still stepping about 60 cm (24 in) past the sides and foot. Best for small rooms or when you want to show off nice flooring. Two runners flanking the bed are a good alternative here.

FAQ

What size rug goes under a queen bed?

It depends on your room and how much of the bed you want covered — use the simulator above. As a rule, the rug should reach about 60 cm (24 in) beyond the bed on each exposed side and the foot, so a queen usually lands somewhere between a compact accent rug and a large 270 × 370 cm (9 × 12 ft) rug.

Should the rug go fully under the bed?

It can (the roomy look), but it isn’t required. The most popular approach is the standard placement — tucking the rug under the lower two-thirds and leaving the nightstands off. It looks intentional and uses a smaller, cheaper rug.

How far should the rug extend past the bed?

About 60 cm (24 in) on each exposed side and at the foot — or up to the wall, whichever comes first. That’s enough to frame the bed and give you a soft step down on both sides.

Can I use runners instead of one big rug?

Yes. Two runners, one on each side of the bed, are a budget-friendly alternative that still gives a warm landing — ideal when you like your flooring and don’t want to cover it.


Bed dimensions are standard US/Western sizes. The simulator shows a computed rug size — round to the nearest rug you can actually buy, and always tape out the outline before purchasing.
