Standard Furniture Dimensions and Clearances: Every Number You Need

Most bad rooms are not badly styled. They are badly measured. A sofa 20 cm too deep, a coffee table 15 cm too close, a dining table that leaves no room to stand up — none of those show in a photo, and all of them make the room quietly annoying to live in.

These are the numbers professional plans are drawn to. Metric first, imperial in brackets. Where a range is given, the low end is the tight-but-legal figure and the high end is what actually feels comfortable.

The five clearances that matter more than any piece of furniture

Before choosing anything, protect the empty space. Furniture is easy to swap; a room whose circulation is broken stays broken.

One rule sits above all of these: a door swing is a circle with a radius equal to the door width. A standard 80 cm interior door sweeps 80 cm of floor. Nothing may live in that arc, including a rug edge that lifts.

Living room

Seating

Seat height is the number nobody checks and everybody feels. Anything below 40 cm is a lounge chair you fall into; anything above 48 cm dangles shorter legs. If you are mixing pieces, keep every seat height within about 3 cm of the others or the group reads as a jumble.

Tables and TV

Screen distance is arithmetic, not preference. For 4K content, sit between 1.5x and 2.5x the diagonal.

Mount the centre of the screen at 100–110 cm from the floor. The common mistake is hanging a TV above a fireplace, which typically puts the centre at 150 cm and forces a 15–20 degree neck tilt for the whole film.

Rug sizing has enough rules of its own that it lives in a separate piece — see the rug size guide for the sofa-to-rug arithmetic, and furniture arrangement rules for how to place the group once the sizes are settled.

Dining room

Seating capacity is decided by edge length, not by table area. Each person needs 60 cm (24 in) of table edge and 30–40 cm of depth.

Standard table height is 74–76 cm. Chair seat height is 45–47 cm, which leaves the 28–30 cm of thigh clearance a person needs. An apron or a thick tabletop eats into that: measure from the floor to the underside of the table, not to the top, and keep it above 63 cm.

To size the room, add the clearance to the table on every side:

• Table length + 2 x 90 cm (chairs only, wall behind) = minimum room length
• Table length + 2 x 115 cm (people walking behind seated diners) = comfortable room length

So a 180 cm table needs a 360 cm room at minimum and 410 cm to be pleasant. Hang the pendant 75–90 cm above the tabletop, and make it roughly half to two-thirds the table width.

Bedroom

Note the trap: a “king” in Europe is 180 cm wide and a “king” in the US is 193 cm. Bedding bought in the wrong market will not fit.

Around the bed:

• 60–75 cm of clear floor on each side you use
• 90 cm at the foot if it is a walking route, 60 cm if it is a dead end
• Nightstand top within 5 cm of the mattress top (mattress surface usually lands at 55–65 cm)
• Wardrobe: 60 cm deep for hanging, and a hinged door needs its own width in front of it
• A chest of drawers needs its drawer depth plus 60 cm to stand in

The smallest bedroom that works with a double bed and a wardrobe is about 2.7 x 3.0 m. Below that you are choosing between the wardrobe and walking around the bed — which is exactly the trade-off worth previewing before you buy. Feng shui bedroom layout rules covers where in the room the bed itself should sit.

Home office

The desk depth is the one people get wrong. A 27-inch monitor on a 50 cm desk sits about 40 cm from your eyes, which is close enough to cause eye strain within an hour. If the desk is shallow, a monitor arm buys back 15 cm.

For the rest of the setup — where the desk faces, what the camera sees — see home office design ideas and the video call background guide.

Kitchen

The 120 cm aisle is not a luxury figure. An open dishwasher door is about 60 cm deep, an open oven door is 50–55 cm, and a person crouching in front of either occupies 90 cm. Put a 100 cm aisle between a dishwasher and an opposite drawer bank and the two cannot be open at once.

Bar stool height follows the counter: a 90 cm counter takes a 60–65 cm seat, a 105–110 cm bar takes a 75 cm seat. Leave 25–30 cm between the seat top and the underside of the counter.

More on fitting all of this into a tight footprint in small kitchen ideas.

Bathroom

Walls, art and hanging heights

The 145–150 cm rule is gallery convention: it puts the artwork’s centre at average standing eye level. It applies to the centre of the whole arrangement, so in a gallery wall you treat the group as one rectangle — the gallery wall guide has the layout method. Curtain heights follow their own rules, covered in the curtain length and hanging guide.

Storage and shelving

Doorways, and the sofa that does not fit

Before buying anything large, measure the route, not just the room. The classic failure is a sofa that fits the living room perfectly and cannot get past the stairwell.

• Standard interior door: 76–82 cm wide, 200–210 cm tall
• Standard entry door: 90 cm wide
• Corridor: 90–105 cm
• Stair width: 90 cm, with about 200 cm of headroom

A sofa passes through a doorway if either its height or its depth is less than the door width — you tip it on its side and walk it through. A 95 cm deep sofa with a 90 cm back height will not go through a 80 cm door in any orientation, and no amount of angling fixes it. Check the tightest turn too: the diagonal of the corridor at a 90 degree turn has to exceed the sofa length.

Ceilings and proportion

Check the numbers on your actual room

Tables like these tell you what fits. They do not tell you what it will feel like, and that is where most of the doubt lives — a 240 cm sofa is “correct” for the room and can still swallow it.

That is the gap Architectural AI closes: photograph the room, apply a style or a layout change, and look at the result on your own walls before anything is ordered. Pair it with a room measuring checklist so the plan and the preview agree, and read design mistakes that make a room look smaller for the proportion errors that survive correct measurements.

Frequently asked questions

How much space do you need to walk between furniture?

A main traffic route through a room needs 90 cm (36 in). A secondary path that only one person uses at a time can drop to 75 cm (30 in), and 60 cm (24 in) is the hard floor — that is roughly shoulder width plus a hand carrying something. Between the front of a sofa and a coffee table, 40–45 cm (16–18 in) is correct, because you are stepping sideways rather than walking through.

What are standard sofa dimensions?

A three-seat sofa is 210–240 cm (83–94 in) long, 85–95 cm (34–37 in) deep and 80–90 cm (32–35 in) tall at the back, with a seat height of 42–45 cm (17–18 in). A loveseat is 150–180 cm, and a corner sectional typically runs 250–300 cm on its long arm. Deep-seat lounge sofas add 10–15 cm to the depth, which is exactly what makes them feel oversized in a small room.

How far should a TV be from the sofa?

For a 4K screen, sit at roughly 1.5 times the screen diagonal for a cinematic view and up to 2.5 times for comfortable everyday viewing. A 55-inch (140 cm) TV therefore wants a seating distance of 2.1–3.5 m, and a 65-inch (165 cm) wants 2.5–4.1 m. Mount it so the centre of the screen lands at 100–110 cm from the floor, which is seated eye level for most adults.

How much space does a dining chair need behind it?

A dining chair travels 50–55 cm (20–22 in) backwards when someone stands up, so that is the minimum from table edge to whatever is behind. If people also need to walk past the seated diner, budget 90–115 cm (36–45 in) from the table edge to the wall or sideboard.

What is the standard kitchen counter and cabinet height?

Base cabinets and counters sit at 90 cm (36 in) in the US and 90–92 cm in most of Europe, with a 60 cm (24 in) counter depth. Wall cabinets start 45–50 cm (18–20 in) above the counter and their tops usually land at 210–220 cm. Over a hob, keep 65–75 cm of clearance to the extractor depending on whether the hob is electric or gas.

How much room do you need around a bed?

Leave 60–75 cm (24–30 in) of clear floor on each side you walk down, and 90 cm (36 in) at the foot if that is a route through the room — 60 cm if it is a dead end. Add the drawer depth of any chest that opens into that path: a 50 cm drawer in a 60 cm gap leaves 10 cm to stand in, which is why the drawer never gets opened fully.
