The question I'm asked more than any other.

If I had to guess the single most common mistake people make when buying a rug, it would be this: buying one that's too small. A rug size guide sounds like a dry technical exercise, but getting it right is actually one of the most impactful decisions you can make for how a room looks and feels.

A rug that's the wrong size doesn't just look off. It makes the furniture feel unmoored, the room feel smaller, and the whole space lose the sense of intention that good interior design depends on.

The good news is that sizing a rug correctly is not complicated. There are a few clear principles, and once you understand them you'll be able to walk into any room and know within a few minutes what you need.

This guide covers every room in the house. I've also included a reference table, a note on how to handle furniture placement, and some practical advice on measuring before you order. Start at the section that's most relevant to you, or read it straight through. It's not long.

The One Rule That Covers Most Situations

Before the room-by-room breakdown, there's one principle that applies almost everywhere: the rug should be large enough that the front legs of your main furniture pieces can rest on it comfortably.

This single rule solves about 80 percent of sizing questions. When the front legs of your sofa and chairs sit on the rug, the whole seating group is visually tied together. The rug becomes the foundation for the room rather than just a decorative object floating in the middle of it.

The opposite arrangement, where all the furniture sits completely off the rug, tends to make the rug look like it's been placed in the wrong room. It happens when people underestimate how large a rug needs to be, and it's by far the most common error I see.

The rug should be the floor of your room, not a mat in the middle of it.

Rug Size Guide: Quick Reference by Room

Room	Recommended Rug Size	What This Achieves
Small living room	5x8 ft / 150x240 cm	Defines the seating zone without overwhelming the space
Medium living room	6x9 ft 180x270 cm	Anchors the furniture grouping with room to breathe
Large living room	8x10 ft or 9x12 ft / 240x300 cm or 270x365 cm	Creates a full room anchor, all furniture legs comfortably on the rug
Dining room	8x10 ft / 240x300 cm (minimum)	Allows chairs to remain on the rug when pulled out
Master bedroom	8x10 ft / 240x300 cm	Extends on three sides of the bed, generous underfoot when rising
Queen bedroom	6x9 ft / 180x270 cm	Clean framing on both sides and the foot of the bed
Twin / single bedroom	4x6 ft / 120x180 cm	A warm landing on one side or centred at the foot of the bed
Home office	5x8 ft / 150x240 cm	Grounds the desk and chair zone, adds acoustic softness
Hallway / runner	2.5x8 ft or 2.5x10 ft / 75x240 cm or 75x300 cm	Runs the length of the corridor with a few inches clearance each end
Entryway	3x5 ft / 90x150 cm	Welcoming scale without crowding the door swing

Note: All sizes are approximate. Always measure your specific room and furniture layout before ordering. Standard international rug sizes vary slightly between manufacturers.

Living Room: The Room Where Size Matters Most

The living room is where most people spend the most time getting the size wrong, partly because the furniture groupings are larger and more complex than in any other room.

The most practical starting point is to measure the furniture grouping, not the room. Draw an imaginary boundary around your sofa and chairs when they're arranged the way you want them, then add roughly 30 to 45 cm (12 to 18 inches) on each side. That's the minimum rug size that will look intentional.

Small living rooms (under 4 x 4 metres / 12 x 12 feet)

A 5x8 ft rug (150x240 cm) is usually the right starting point. It's large enough to anchor a compact sofa and two chairs with front legs on, without crowding the walls.

Avoid going smaller. A 4x6 ft rug in a living room almost always reads as a mistake, regardless of how thoughtful the rest of the room is.

Medium living rooms (4 x 5 metres / 12 x 15 feet range)

A 6x9 ft (180x270 cm) or 8x10 ft (240x300 cm) rug gives you the right scale. The larger of the two is almost always worth the extra investment if your furniture grouping is substantial.

Large or open-plan living rooms

Here a 9x12 ft (270x365 cm) rug is often the right call, and in very large open-plan spaces, two rugs used deliberately to define two zones can work better than a single very large piece.

If you're unsure between two sizes, go larger. Almost no one regrets buying a rug that's slightly too big. Almost everyone regrets the one that's slightly too small.

Furniture Placement: All Legs On, or Front Legs Only?

This comes up constantly and the answer depends on the size of the rug and the size of the room.

Arrangement	What It Looks Like	When It Works
All legs on	Entire sofa and chairs sit fully on the rug	Large rugs in larger rooms. The most grounded, most formal look.
Front legs on	Only the front legs of each piece rest on the rug	The most common and most forgiving approach. Works in most rooms.
All legs off	Rug sits entirely in front of the furniture grouping	Only works for very small accent rugs. Rarely looks intentional in a living room.

For most homes, front legs on is the right default. It's the most flexible arrangement and it works across a wide range of rug sizes and room configurations.

Dining Room: How to Measure It Properly

The dining room has a specific and non-negotiable rule. The rug must be large enough that dining chairs remain on the rug even when pulled out from the table. If a chair slides off the rug edge every time someone sits down or stands up, the rug is too small.

To measure: stand at your table with all chairs pushed in. Measure the full length and width of the table, then add 60 cm (24 inches) to each side. That's your minimum rug size.

For most standard dining tables seating six to eight people, this means a minimum of 8x10 ft (240x300 cm). For a large table seating eight to ten, a 9x12 ft (270x365 cm) rug is more appropriate.

Practical tip: use a flatweave or low-pile rug under a dining table. High-pile rugs make chair movement difficult and collect crumbs more readily.

Bedroom: The Three Ways to Place a Rug

The bedroom gives you more flexibility than any other room because there are three genuinely good approaches, each with a different visual effect.

Approach 1: The large rug that extends on three sides

Place an 8x10 ft or 9x12 ft rug under the bed so that it extends roughly 60 to 90 cm (24 to 36 inches) on both sides and at the foot. The bedside tables can sit just off the edge of the rug or on it. This is the most generous and grounded approach, and it makes even a modest bedroom feel considered.

Approach 2: A rug at the foot of the bed only

A 4x6 ft or 5x8 ft rug placed across the foot of the bed gives a warm landing when you rise in the morning without requiring a very large piece. It works particularly well in smaller bedrooms or when the bed is the dominant piece and the floor is beautiful enough to stay partially visible.

Approach 3: Two matching runners on either side

Two runners placed along each side of the bed, typically 2.5x6 ft or 2.5x8 ft, give the same practical warmth underfoot as a large rug but with a lighter, more minimal look. This works well in contemporary or Scandinavian-influenced interiors where visual weight is carefully managed.

Hallways and Entryways: Getting the Proportions Right

A hallway runner should run most of the length of the corridor, with a gap of roughly 15 to 20 cm at each end and a clearance of a few centimetres on each side. A runner that's too short looks as though it's been borrowed from another room.

For width: most hallways suit a runner between 60 and 90 cm wide (2 to 3 feet). Measure the corridor width and aim for a runner that leaves a consistent border of bare floor on each side.

For an entryway, a 3x5 ft or 4x6 ft rug is usually the right scale. The main practical consideration is that it sits flat and doesn't impede the door swing.

Home Office and Other Rooms

For a home office, the rug should be large enough to sit under the desk and chair, with enough space to roll the chair back comfortably without the back legs dropping off the rug edge. A 5x8 ft rug tends to work well for most desk setups.

For a reading corner, a 4x6 ft rug placed under the chair and a side table creates a defined zone within a larger room. This is one of the most underused techniques in interior design. A well-placed rug can create a room within a room in a way that furniture arrangement alone cannot.

How to Measure Before You Order

Before ordering any rug, do this. It takes ten minutes and saves a great deal of regret.

Mark out the intended rug size on your floor using painter's tape or newspaper sheets. Stand back and look at it from the doorway and from each corner of the room.
Sit in your furniture as you normally would and check that the front legs would comfortably rest on the marked area.
Check that the marked area doesn't crowd doorways or fireplace hearths.
Take a photograph. Sometimes a proportion that looks fine in person looks clearly wrong in a photo, and vice versa.

If you're considering a custom size, this step is especially worthwhile. Most of the custom rug orders we receive are from people who measured carefully first and found that a standard size didn't quite fit their layout.

When a Standard Size Isn't Right

Standard rug sizes cover most situations. But rooms are rarely standard and furniture arrangements are rarely perfectly symmetrical. Sometimes the space genuinely calls for a non-standard dimension.

Custom rugs are more accessible than most people expect. At Tantuka we make custom rugs in both hand-knotted and hand-tufted construction, built to whatever dimensions your room requires. The design, material, and colour are all worked around your space rather than the other way around.

If you've measured carefully and found that a standard size consistently looks slightly wrong, a custom piece is probably the right answer.

Questions I Get Asked

What size rug do I need for a 3-seater sofa?

For a 3-seater sofa with two chairs, a minimum of 6x9 ft (180x270 cm) works in a medium room. An 8x10 ft (240x300 cm) is better if the room size allows it. The front legs of all seating pieces should rest comfortably on the rug.

Can a rug be too big for a room?

Rarely, and much less commonly than being too small. The main risk is a rug so large it touches the walls on multiple sides, which can make the room feel like it has wall-to-wall carpeting. As a general guide, leave at least 30 to 45 cm (12 to 18 inches) of bare floor between the rug edge and the walls.

Should a rug go under a bed or in front of it?

Both approaches work. A large rug extending on three sides of the bed is the most common and most generous option. A rug placed at the foot of the bed only is a good alternative for smaller rooms or where you want a lighter visual effect.

What size rug fits under a king-size bed?

For a king-size bed, an 8x10 ft (240x300 cm) rug allows the rug to extend on both sides and at the foot. A 9x12 ft (270x365 cm) gives an even more generous extension if the room size permits.

What rug size is best for a small apartment living room?

In a compact living room, a 5x8 ft (150x240 cm) rug is usually the most practical choice. Resist the temptation to go smaller. In a small room a proportionally correct rug actually makes the space feel larger, not smaller.

Do you make rugs in non-standard sizes?

Yes. Custom sizes are one of the most frequent requests we receive. If your room or furniture layout calls for a non-standard dimension, we can build the rug around it.
