How much space do you need between furniture?
Whether a piece fits is the first question. Whether you can still walk past it, open its drawers and get out of the sofa is the second one — and it is the one that decides whether a room works. A layout can be geometrically correct and still unlivable, because furniture needs the empty space around it as much as the space underneath it. These are the gaps that matter, what each one is for, and how to check them on your own plan instead of guessing.
Every clearance on this page exists for a physical reason, not a decorating one. A walkway is 90 cm because that is a person plus the width of what they are carrying. A dining chair needs 75 cm behind it because that is how far the chair travels before you can sit down. A chest of drawers needs 90 cm in front because the drawer itself comes out 45–55 cm and you still have to stand somewhere to reach into it. Once you know what a number is for, you know which ones you can shave in a small room and which ones make the furniture genuinely unusable if you take them away. Measure the gaps the same way you measured the pieces — on the plan, at the same scale — and the answer stops being a guess.
Clearances that actually work, in cm and inches
Comfortable is what you should design for. Tight but workable is what a small room can get away with — go below it and something stops functioning rather than merely feeling cramped. The last column is the reason the gap exists, which is what tells you whether you can borrow from it.
| Gap between | Comfortable | Tight but workable | Why the gap exists |
|---|---|---|---|
| Sofa front and coffee table | 40 cm (16 in) | 30 cm (12 in) | Room for your shins and feet as you stand up, while the table stays close enough to reach a mug sitting down. Past about 50 cm you have to lean or stand, which is why bigger is not better here |
| Main walkway through a room | 90 cm (36 in) | 75 cm (30 in) | One person plus what they are carrying — a laundry basket, a box, a child. Below 75 cm two people cannot pass at all and the route becomes single file |
| Secondary path used occasionally | 75 cm (30 in) | 60 cm (24 in) | Shoulder width with a little margin. Fine for the side of the bed you reach the window from; not fine for the route you take every morning |
| Dining table edge and the wall behind a chair | 75 cm (30 in) | 60 cm (24 in) | How far the chair has to slide back before a person can sit down or get up. This is measured from the table edge, not the chair back |
| Dining chair with someone walking behind it | 100–120 cm (40–48 in) | 90 cm (36 in) | The chair pull-out distance plus a walkway on top of it. The most commonly missed number in a dining room, because it only fails when the table is full |
| Beside a bed you get into from that side | 60–75 cm (24–30 in) | 50 cm (20 in) | Space to sit on the edge, stand up, and make the bed. A side pushed against a wall needs nothing, but then only one person can get in |
| Foot of the bed, when it is a walkway | 90 cm (36 in) | 60 cm (24 in) | A route, so it follows walkway rules. If nothing passes the foot of the bed, this number disappears entirely — one of the easiest gaps to reclaim in a small bedroom |
| In front of a chest of drawers or dresser | 90 cm (36 in) | 75 cm (30 in) | The drawer comes forward 45–55 cm and you still have to stand in front of it and look down. This is not a comfort margin — below it the drawers stop opening fully |
| In front of a wardrobe with hinged doors | 90–110 cm (36–43 in) | 75 cm (30 in) | The door swings about 60 cm into the room before you can reach past it. Sliding doors remove this constraint completely, which is usually the real fix in a narrow bedroom |
| Sofa and the television | 1.5–2.5× the screen diagonal | 1.2× the diagonal | Viewing distance, not circulation. A 55 in (140 cm) screen wants roughly 2.1–3.5 m of seating distance — often the number that decides where the sofa goes in a narrow living room |
| Two sofas or chairs facing each other | 180–240 cm (6–8 ft) | 150 cm (5 ft) | Close enough to talk without raising your voice, far enough not to bump knees. Beyond about 270 cm a conversation group stops reading as one group |
Read the table twice: once for the piece you are buying, once for the route past it. Most layouts fail on the second reading — the sofa fits, the coffee table fits, and the gap left between them and the wall turns out to be 55 cm. Draw the pieces on your own floor plan in ToScale and the leftover space is visible at true scale, so you can see whether the gap is a walkway or a squeeze instead of working it out in your head.
Frequently asked questions
- How much space should there be between a sofa and a coffee table?
- About 40 cm (16 in), and anywhere from 30 to 45 cm works. The gap has to clear your shins when you stand up while keeping the table within arm's reach when you are sitting. Under 30 cm you catch your legs on the corners every time you get up; over about 50 cm you have to stand up to reach anything on the table, which defeats the point of having it there.
- How wide does a walkway between furniture need to be?
- A main route through a room wants 90 cm (36 in) — one person plus whatever they are carrying. A path used occasionally can drop to 75 cm, and 60 cm is the absolute squeeze where one person passes sideways and nobody passes another. The width that matters is the narrowest point along the route, not the average.
- How much room do you need behind a dining chair?
- Measure from the table edge: 75 cm (30 in) lets someone pull the chair out and sit down, and 100–120 cm lets another person walk behind them while they are seated. The second number is the one people forget, because the problem only shows up when every seat is occupied — which is exactly when it matters.
- How much clearance does a chest of drawers need in front of it?
- About 90 cm (36 in). A drawer travels 45–55 cm out of the carcass, and you have to stand in front of it to reach in. This clearance is different from a walkway — a narrow walkway is annoying, but a chest with 40 cm in front of it has drawers that physically cannot open all the way, which makes the piece unusable. The classic version of this mistake is putting a chest at the foot of a bed and finding the drawers hit the mattress.
- My room is too small for all of these. What should I give up first?
- Give up secondary paths before main ones, and the foot of the bed before the sides you actually get in from. Shave the sofa-to-coffee-table gap to 30 cm, or drop the coffee table for a side table. What you should not give up is the space a drawer or a door needs to open, because that clearance is not comfort — it is the only thing that makes the furniture work at all. If the numbers refuse to fit, the answer is usually a smaller piece or sliding doors rather than a tighter gap.
