Rug Under Bed Size: What Actually Fits a Double, Queen and King

Almost every rug guide sizes the rug to the mattress. A queen mattress is 153cm wide, so a 240cm rug sounds generous: 43cm of rug showing each side, plenty to stand on. Then the bed arrives, the frame turns out to be 171cm across, and the margin quietly drops to 34.5cm. Enough to look thin, not enough to land both feet on.

The frame is the number that matters, and across the five Cedora bedroom ranges it moves by nearly nine centimetres at the same mattress size. Measure that first and the rug decision stops being a guess.

Key Takeaways

• Size the rug to the bed frame, not the mattress. A queen frame runs 162.4cm to 171cm wide across these ranges.
• Allow at least 45cm of rug showing each side of the bed, and 60cm if you want it to look deliberate.
• Full coverage under a queen or king wants a 300 x 400cm rug. Almost nothing smaller works.
• The cheaper answer is a two thirds layout: a 200 x 290cm rug turned sideways, starting below the bedside tables.
• Bedside tables are 55cm wide. Deciding whether they stand on the rug changes the width you need by 110cm.

The Frame Is Wider Than the Mattress, and by More Than You Think

Bed frames add timber to every side of the mattress. How much depends on the range, and the spread is larger than most people plan for. Across the five Cedora bedroom ranges a queen frame starts at 162.4cm and finishes at 171cm, which is an 8.6cm swing on an identical mattress.

The Liverpool Pine Queen Bed Frame is the widest at 171cm, because the upholstered headboard and footboard sit proud of the timber frame. The Bristol Pine Queen Bed Frame is the narrowest at 162.4cm. If you already own the rug, that difference decides whether the bed looks framed or stranded.

Length matters less but is worth writing down, because it sets how far the rug has to run past the foot of the bed. A Liverpool queen is 224cm long and a Bristol queen is 215.5cm. Nine centimetres of bed is nine centimetres of rug you either have or you do not.

How Much Rug Should Show Beside the Bed

The point of a rug under a bed is the first step of the morning. That step has to land entirely on the rug, which means the rug must be wider than the frame by at least the length of a foot plus a margin for where you actually put it down. In practice that is 45cm each side as a floor, and 60cm each side if you want the rug to read as a border rather than an accident.

Turn that into a rug width. Take the frame width and add twice the margin:

• Double at 156cm plus 90cm equals 246cm of rug width
• Queen at 171cm plus 90cm equals 261cm of rug width
• King at 201cm plus 90cm equals 291cm of rug width

Rugs here are sold in a short list of sizes, and only one of them clears 261cm: the 300 x 400. A 240 x 330 under a Liverpool queen leaves 34.5cm each side, narrower than the bedside table standing next to it. That is the specific mistake this article exists to prevent.

The Two Layouts That Actually Work

Full coverage: the whole bed sits on the rug

This is the look most people picture, and it is the expensive one. For a queen you want 300 x 400cm, which gives 64.5cm of rug each side of a Liverpool frame and 88cm past the foot. For a king the same rug gives 49.5cm each side, workable but tight. Below 300cm wide, full coverage stops being worth doing.

It also needs the room. A 300cm rug in a 3.4m bedroom leaves 20cm of bare floor on each side, and at that point you have carpeted the room rather than laid a rug.

Two thirds: the rug starts below the bedside tables

Lay a 200 x 290cm rug sideways so the 290cm runs across the room. Against a 171cm queen frame that is 59.5cm of rug each side, right in the comfortable band. The 200cm depth covers the lower 140cm of the bed and still runs 60cm past the foot, so it reads as a full rug from the doorway at a fraction of the price of a 300 x 400.

The bedside tables stay off it, which is the point. A rug edge running under one leg of a bedside table is the detail that makes a finished room look unresolved.

Bedside Tables Change the Maths by 110cm

Every Cedora bedside table is 55cm wide, or 60cm on the Liverpool. Two of them, one each side, is 110cm of extra width the rug has to cover if you want them standing on it. Added to a queen frame that is 281cm before you allow any margin at all, and 371cm if you want 45cm showing outside the tables.

No standard rug does that, so the honest answer is that bedside tables belong on the floor in almost every bedroom. Choose the two thirds layout, start the rug below the table line, and the problem disappears.

The exception is a room wide enough for the full 300 x 400. There a Bristol Pine 2 Drawer Bedside Table at 55 x 45cm sits comfortably on the rug with the frame still clear of the edge. If you are working out how the tables relate to the bed in the first place, we covered that in matching bedside tables to your bed frame.

Check the Room Before You Check the Rug

A rug needs bare floor around it or it stops reading as a rug. The working rule is 20cm to 40cm of visible floor between the rug edge and the wall or the wardrobe. Measure the room, subtract 40cm from each wall you can see floor along, and that is your ceiling on rug width before anything about the bed is considered.

In a 3.6m bedroom that leaves 280cm to play with. A 240 x 330 fits with room to spare and a 300 x 400 does not, which usually settles the layout question before the bed does.

One more check. A queen bed with two bedside tables needs 273cm of clear wall, which is more than many bedrooms have once the door swing and the robe are placed. We ran those numbers in the 273cm wall problem, and it is worth reading before you buy a rug that assumes both tables are staying.

Frequently Asked Questions

What size rug goes under a queen bed?

A 300 x 400cm rug if you want the whole bed on it, which leaves 64.5cm of rug each side of a 171cm frame. If that is too large for the room, use a 200 x 290cm rug turned sideways so it starts below the bedside tables and runs past the foot of the bed.

Should the rug go under the bedside tables?

In most bedrooms, no. Every Cedora bedside table is 55cm wide, so covering both adds 110cm to the rug width and pushes a queen past 370cm. Start the rug below the table line instead and leave the tables on the floor.

How much rug should show on each side of the bed?

At least 45cm, which is enough for your first step out of bed to land on the rug. Sixty centimetres looks more deliberate. Anything under 40cm reads as a rug that was bought for a smaller bed.

Do I measure the mattress or the bed frame?

The frame. A queen mattress is 153cm wide, but a queen frame in these ranges runs from 162.4cm on the Bristol to 171cm on the Liverpool. Sizing to the mattress can cost you nearly 20cm of rug you thought you had.

Is a rug under the bed worth it on floorboards?

Yes, for two reasons that have nothing to do with looks. It takes the cold out of the first step in winter, and it absorbs the sound that a hard floor bounces around a room with little else soft in it.
