Which Rug Size Equals How Many m²?
Rug sizes are given in centimetres, but most people think of what they need in square metres. The table below shows which standard rug sizes correspond to the most searched-for square-metre values. The figures are calculated with the formula width (cm) × length (cm) ÷ 10,000.
| Square metres | Standard rug sizes | Actual area | Suitable room |
|---|---|---|---|
| 1 m² rug | 80x120 cm | 0.96 m² | Hallway, in front of the bathroom |
| 2 m² rug | 100x200 cm · 120x180 cm | 2.00 – 2.16 m² | Bedside rug, children's room |
| 3 m² rug | 120x250 cm · 160x200 cm | 3.00 – 3.20 m² | Small sitting room, study |
| 4 m² rug | 160x230 cm · 200x200 cm | 3.68 – 4.00 m² | Medium-sized living room, bedroom |
| 5 m² rug | 160x300 cm · 200x250 cm | 4.80 – 5.00 m² | Living room, large bedroom |
| 6 m² rug | 200x300 cm · 240x250 cm | 6.00 m² | Standard living room (the most popular choice) |
| 8 m² rug | 200x400 cm · 240x340 cm | 8.00 – 8.16 m² | Large living room, dining room |
| 12 m² rug | 300x400 cm · 240x500 cm | 12.00 m² | Very large living room, open-plan space |
If you already know the square metres you need, you can go straight to the matching collection: 1–4 m² rugs · 4–6 m² rugs · 6–12 m² rugs · rugs of 12 m² and above.
Recommended Rug Size by Room Type
The practical rule for finding the right size: deduct a margin from each side of your room dimensions. How much you leave depends on how the room is used.
| Room type | Border margin | Why | Popular size |
|---|---|---|---|
| Living room | ~35 cm | At least the front legs of the furniture should sit on the rug | 200x300 cm |
| Dining room | ~25 cm | Chair legs should still be on the rug when pulled back | 200x300 · 240x340 cm |
| Bedroom | ~45 cm | Your feet should land on the rug when you get out of bed | 160x230 · 200x300 cm |
| Hallway / corridor | ~15 cm | A transit area; a runner shape works best | 80x150 · 80x300 cm |
In the dining room you can run a second check if you know your table size: add +65 cm to each side of the table dimensions; the result keeps the chairs on the rug even when they are pulled back.
How to Measure for a Rug
- Measure the length and width of the room with a tape measure.
- Calculate the rug size so that at least 30-40 cm remains free along each wall.
- Sketch the position of your seating group.
- Decide which area the rug should cover.
- Match it against the standard rug sizes (table below).
Common Sizing Mistakes
- A rug that is too small: a rug floating like an "island" in the middle of the seating group makes the room look cluttered.
- A rug touching the walls: if the rug is large enough to reach the wall, the room feels smaller and the rug curls up at the edges.
- The wrong proportion: using a square rug in a long, narrow room throws off the proportions.
- Ignoring colour: light rugs make a space feel wider and dark ones narrower; think about colour alongside size.
A Practical Test
Before you decide, mark out the size you have in mind on the floor with masking tape. Live with it for a few days and see for yourself whether that size really works. This simple method significantly reduces the risk of choosing the wrong one.
Frequently Asked Questions
A 6 square metre rug is how many cm by how many cm?
In standard sizes, a 6 m² rug corresponds to 200x300 cm or 240x250 cm. The most popular choice is 200x300 cm, which suits medium to large living rooms.
What size is a 4 square metre rug?
The standard sizes closest to 4 m² are 200x200 cm (exactly 4 m²) and 160x230 cm (3.68 m²). They are the usual choice for square rooms and medium-sized living rooms.
How do I calculate a rug's area in square metres?
Multiply the width and length in centimetres and divide by 10,000. Example: 200 x 300 = 60,000 ÷ 10,000 = 6 m².
How many m² of rug should I buy for a living room?
In a standard living room (roughly 3.5 x 4.5 m), leaving about 35 cm on each side makes 200x300 cm / 6 m² the most balanced result. Enter your own room dimensions in the calculator above for a precise recommendation.
What happens if the rug is bigger than the room?
A rug pressed against the walls makes the space look smaller than it is and can block the door from opening. We recommend leaving at least 15–20 cm of floor visible on each side.
