The right rug pulls a room together. The wrong size makes even beautiful furniture look like it's floating. Most rug mistakes come down to two things: the rug is too small, or the shape doesn't suit the furniture. This guide covers the rug sizes and shapes that work in every room, the rules our designers use, and the rug trends we're loving for 2026.

What size rug do I need? The quick guide
| Room | Common rug sizes | The rule |
|---|---|---|
| Living room (3-seater sofa) | 200 × 300 cm | At least the front legs of the sofa and chairs sit on the rug |
| Large living room or modular sofa | 250 × 350 cm, 300 × 400 cm | All furniture fully on the rug, or front legs on |
| Dining room (6-seater, 180 cm table) | 250 × 350 cm | Table plus 60–75 cm on every side |
| Dining room (8–10 seater) | 300 × 400 cm | Chairs stay on the rug when pulled out |
| Round dining table (120–150 cm) | 240–300 cm round | Diameter of the table plus about 120–150 cm |
| Queen bed | 200 × 300 cm (sideways) | Extends about 50–60 cm each side of the bed |
| King bed | 250 × 350 cm, 300 × 400 cm | Extends 60–90 cm each side, under the lower two-thirds |
| Hallway | 80 cm wide runners, 200–500 cm long | 10–15 cm of floor showing each side |
| Reading corner or nursery | 150–200 cm round | Anchors one chair and a side table |
As a rule, leave about 20–45 cm of floor showing between the rug and the walls. In open-plan spaces, use the rug to define the zone: it should be the size of the furniture grouping, not the whole room.
How to choose a living room rug
There are three layouts that always work:
- All legs on. The sofa, chairs and coffee table sit fully on the rug. The most luxurious look; best for large rooms and open-plan spaces.
- Front legs on. The front legs of the sofa and chairs sit on the rug, the back legs on the floor. The most popular choice for most living rooms.
- Coffee table only. Only works for small rooms, layered rugs or a statement round rug. A small rug floating in the middle of the seating is the most common rug mistake.
Your rug should also be about 15–20 cm wider than your sofa on each side. For a 240 cm sofa, look for a rug at least 270–280 cm long.
How to choose a dining room rug
A dining rug must be big enough for chairs to stay on it when they're pulled out, or they'll catch on the edge every meal. Measure the table and add 60–75 cm on every side. Choose a low pile or flat weave so chairs slide easily, and a pattern or mid-tone that forgives the odd spill.
- Rectangular or oval table: a rectangular rug that follows the table's shape.
- Round table: a round rug, or a square rug in a square room.
- Bench seating: the same rule applies, so measure from the bench, not the table.
How to choose a bedroom rug
You want something soft underfoot when you step out of bed. Place a large rug under the lower two-thirds of the bed, stopping just in front of the bedside tables, so it extends 50–90 cm on each side and at the foot. Prefer to keep the floor visible? Use two runners, one each side of the bed, or a round rug at the foot. A deeper pile or a wool and silk blend feels most luxurious in a bedroom.
Which rug shape is right for your room?
| Shape | Best for | Why it works |
|---|---|---|
| Rectangle | Living rooms, dining rooms, bedrooms | Follows the lines of most rooms and furniture; the easiest choice |
| Round | Round tables, reading corners, curved sofas, entries | Softens hard lines and creates a natural focal point |
| Square | Square rooms and square dining tables | Balances a symmetrical room |
| Organic or irregular | Modern living rooms, curved and sculptural furniture | Adds movement and an art-piece feel; the trend of the moment |
| Runner | Hallways, kitchens, beside beds | Defines walkways and protects high-traffic floors |
| Hide and patchwork | Studies, reading corners, layering | Natural texture that layers beautifully over a larger rug |
Round rugs we love: the La Quinta and Trilogia Circulo art hide rugs, in sizes from 150 to 300 cm. For square rooms, the Oslo Rug comes in square sizes from 200 × 200 cm. For hallways, our Angulo and Nueva Raya runners come in lengths up to 5 metres.
Rug trends for 2026
- Organic and sculptural shapes. Soft, irregular outlines that look like art on the floor, like the Pompidou Sculptural Wool Rug and Fortuna Rug.
- Carved, high-low pile. Texture you can feel, with patterns carved into the pile, like the Botanical Terrain Sculptural Wool Rug and Heritage Rug.
- Warm, earthy tones. Caramel, terracotta, rust and sand, replacing cool greys. See the rust tones of the Viper Hand-Tufted Wool Rug.
- Arches and curves. Rounded motifs that echo curved sofas and arched doorways, like the arches woven into the Viper.
- Stone and nature-inspired designs. Marble veining, agate and water patterns, like the Agatha Rug and River Flux Rug.
- Hand-knotted wool. Investment rugs that last for decades, like the Ribeira Hand-Knotted Wool Rug.
Rug rules: the must-dos and must-don'ts
Do:
- Measure the furniture grouping, then tape the rug outline on the floor before you buy.
- Go bigger if you're between two sizes.
- Use a quality underlay to stop slipping and protect your floors.
- Check door clearance, especially with a thick pile.
- Choose wool, wool blends or performance acrylic for busy family rooms.
Don't:
- Float a small rug in the middle of the seating.
- Run a rug wall to wall; leave a border of floor.
- Put a high-pile rug under a dining table.
- Place silk or viscose rugs in high-traffic areas or near the back door.
- Forget the sun: strong Australian light can fade natural fibres, so rotate your rug every few months.
Rug FAQs
What size rug should go in my living room? For most living rooms, 200 × 300 cm works with a 3-seater sofa. For larger rooms or modular sofas, choose 250 × 350 cm or 300 × 400 cm.
Should my rug go under the sofa? Yes, at least the front legs. It connects the furniture and makes the room feel larger.
How far should a rug be from the wall? About 20–45 cm in most rooms; less in a small room, more in a large one.
Round or rectangular rug under a round table? Round usually looks best, and it keeps all the chairs on the rug.
Can I put a rug on carpet? Yes. Choose a low-pile or flat-weave rug with a carpet-grip underlay so it doesn't creep.
What's the best rug material? Wool is durable, naturally stain-resistant and warm. Silk and viscose add sheen but suit low-traffic rooms. Acrylic and outdoor rugs like the Marley Outdoor Rug are the easiest to clean.
How do I choose a rug colour? Pick a colour from your sofa, cushions or art. Mid-tones and patterns hide wear best; pale rugs suit adult-only rooms.
What if I can't find the right size or colour? Have one made. Our custom rugs can be made in any size from 2 m² to 600 × 800 cm, in any shape and colour, from your own design or ours.
