A rectangular dining table for six people is typically 160 to 180cm long and 90cm wide, and it needs around 90cm of clear floor space behind each chair. Table size and clearance together decide whether a table will work in your room.
This guide sets out standard dining table sizes for 4 to 12 people and explains how to measure your space. It also covers the details that shift the numbers: the chairs you choose, the width of the top and where the legs sit.
Standard dining table sizes explained
The sizes below are the ranges UK furniture makers and interior designers commonly work to. They assume dining chairs without arms and around 60cm of table edge per person.
- 4 people: Rectangular 120-140 x 80-90cm (47-55 x 31-35in), round 90-110cm (35-43in) or square 90-100cm (35-39in)
- 6 people: Rectangular 160-180 x 90cm (63-71 x 35in) or round 120-140cm (47-55in)
- 8 people: Rectangular 200-240 x 90-100cm (79-94 x 35-39in), round 150-160cm (59-63in) or square 150cm (59in)
- 10 people: Rectangular 240-280 x 100cm (94-110 x 39in) or round 180cm (71in)
- 12 people: Rectangular 300 x 100-110cm (118 x 39-43in)
Each size is a range because seating people comfortably and fitting them in are two different things. A 160cm table seats six with one person at each end. A 180cm table seats six along the sides and can stretch to eight using the ends, depending on the chairs and base. Standard dining table height stays at 74 to 76cm whatever the length.
How much table space does each person need?
The usual working figure is 60cm of table edge per person, but you will see anything from 50cm to 70cm quoted. The difference comes down to the chair and how much elbow room you want.
- 50cm: A squeeze. Fine for extra guests at Christmas or children on a bench, but uncomfortable for every meal.
- 60cm: The standard for dining chairs without arms. Enough room for a place setting and elbows without knocking a neighbour.
- 70cm: For carver chairs, armchairs or a more generous layout. Chairs with arms also need to slide under the table, so check the arm height against the apron (the frame beneath the top) before you buy.
End seats add to that: on a table 90cm wide or more, each end takes one person comfortably, which is how a 160cm table reaches six.
Benches are more flexible, because with no arms or chair backs dividing the space, people can shuffle up. A 180cm bench takes three adults or four children, and it tucks fully under the table when not in use, freeing floor space on that side of the room. You can browse Fairmont Reed dining chairs and benches, or add matching benches when you build your table online.
How wide should a dining table be?
Width gets less attention than length, yet it decides whether a table feels generous or cramped. A comfortable width for people sitting opposite each other is 90 to 100cm. At that width there is room for two place settings plus serving dishes, a water jug or a centrepiece down the middle.
80cm is the practical minimum for two-sided dining. Below that, plates start to meet in the middle and there is nowhere to put anything shared. Narrower tables of 60 to 70cm only work with seating along one side, against a wall or as a breakfast table.
Going wider has limits too. Beyond about 110cm, reaching across for the salt becomes a stretch and conversation across the table starts to feel distant, unless the table is long enough to carry the extra width. Very large tables are the exception: Fairmont Reed has made a 14-seater Dekton® table measuring 3m by 2m, where the extra width keeps the proportions balanced at that length.
In a narrow kitchen-diner, width is often where you can win back space. Choosing an 85cm top instead of 100cm frees 15cm of floor, which you can give to the side people walk past.
How much space do you need around a dining table?
Allow 90cm between the edge of the table and the nearest wall or piece of furniture on any side where people sit. That gives enough room to pull a chair out, sit down and tuck it back in.
- Side with chairs: 90cm (35in)
- Tight side nobody walks behind: 75cm (30in) minimum
- Walkway behind seated diners: 100-120cm (39-47in)
- Next to a kitchen island, oven or fridge door: 100-120cm (39-47in)
The 75cm minimum is workable, but whoever sits on that side will feel hemmed in and has to stand to let anyone pass. If the table backs onto a route through the room, such as the path from the kitchen to the garden doors, use the larger walkway figure.
Measure to the nearest obstruction, not the wall. A radiator, a sideboard or a door that opens into the room all take their share of the clearance. A sideboard 45cm deep, for example, comes off your room measurement before you subtract anything else.
How to measure your room for a dining table
- Measure the dining area. Take the length and width wall to wall. In an open-plan room, decide where the dining zone ends first, using a rug, the position of the pendant light or the edge of the kitchen as the boundary.
- Subtract the clearance. Take 180cm off each measurement (90cm per side) to find the largest table the space can hold. Adjust each side individually if one edge is a walkway or a tight side nobody uses.
- Check for obstructions. Note radiators, door swings, low windowsills, and any sockets or switches you need to reach.
- Mark it out. Outline the tabletop on the floor with masking tape or flattened cardboard, put a chair at it and walk around. It shows how the room feels with the table in place, which measurements alone can't tell you.
Two examples show how this works in typical UK rooms.
A 3.6 x 3m dining room: Subtracting 180cm from each dimension gives a maximum table size of 180 x 120cm. A 180 x 90cm table fits with room to spare and seats six comfortably, with space to squeeze in two more at the ends when needed.
A 4.5 x 3.5m kitchen-diner: One long side backs onto the walkway past the kitchen island, so it needs more room, around 100 to 120cm. With 90cm on the other sides, the largest table the space can take is roughly 270cm long and 140 to 160cm wide. That figure is a ceiling, not a target: a table of around 220 x 100cm would seat eight and leave generous space on every side.
How the table base changes how many people you can seat
Two tables with identical tops can seat a different number of people depending on where the legs are, so look at the base before you settle on a length.
Legs at the corners
The traditional four-leg layout puts a leg at each corner. Anyone sitting at the end has a leg either side of their knees, and on the long sides no chair can go where a leg stands. A 180cm table with corner legs often seats six rather than eight.
Legs or frames set in from the ends
Moving the legs inwards, as sledge, trestle and frame-style bases do, lets the top overhang at each end. The ends become usable seats and chairs can sit closer to the corners, so the same top seats more people. Check that the frame doesn't sit where knees go on the long sides.
Central pedestal
A single pedestal, most often found on round tables, leaves the whole edge free. Nobody has a leg to work around, so a round pedestal table can take an extra guest more easily than a four-legged table of the same size.
Twin pedestals or wide-set frames
Long tables need more support. Twin pedestals or two wide frames keep the ends and most of the sides clear, though the seats directly over each support have less knee room.
When the top and base are chosen separately, as they are with a made-to-order table, the base becomes part of the size decision. You can compare base styles on our table bases page.
Sizing round, oval and square tables
Round tables are sized by diameter. A 120cm round table seats four easily and six closely, while 150cm seats six comfortably and eight at a push. Round tables keep everyone in one conversation and suit square rooms, where a rectangle can leave awkward space at each end. Beyond about 160cm, the centre becomes hard to reach, which limits how large a round table can usefully be.
Oval tables seat about the same number of people as a rectangular table of similar length, sometimes one fewer at the ends. The rounded ends remove the corners people walk into, which helps in tighter rooms or where the table sits near a walkway.
Square tables suit four people at 90 to 100cm. A square table for eight, with two people per side, needs to be around 150cm across, and the room needs to be at least 3.3m square to keep 90cm clear on every side.
When a standard size doesn't fit your room
Standard sizes are built around average rooms and average chairs. If your dining area is long and narrow, sits in an alcove, or needs to seat more people than a standard length allows, a bespoke table avoids the compromise. Every Fairmont Reed table is custom-made in our South Lincolnshire workshop, and our online table builder lets you choose the top, base and length together.
To check a size in person, visit our showroom and sit at our tables, see work in progress at the workshop, or contact us to talk through your room measurements.
Frequently asked questions
What is the standard size of a dining table?
The usual reference point is a six-seater, which measures 160 to 180cm long by 90cm wide at a height of 74 to 76cm. Four-seater tables are typically 120 to 140cm long and eight-seaters 200 to 240cm. Width stays between 80 and 100cm for most tables, increasing only for very long designs.
What size dining table do I need for 6 people?
A rectangular table of 160 to 180cm by 90cm seats six. At 160cm, two people sit on each side and one at each end; at 180cm, three fit along each side. For a round table, choose a diameter of 120 to 140cm. With 90cm of clearance all round, a 180cm table needs a room at least 3.6m long.
What size dining table seats 8?
Eight people need a rectangular table of 200 to 240cm by 90 to 100cm, or a round table of 150 to 160cm. A 200cm table can seat eight using the ends, while 240cm fits four along each side. At this size the base makes a big difference, as corner legs can cost you the end seats.
What size is a 4 seater dining table?
A rectangular four-seater is typically 120 to 140cm long and 80 to 90cm wide. Square tables of 90 to 100cm and round tables of 90 to 110cm also seat four. A 120cm round table is worth considering if you occasionally need to seat five or six.
How much space do you need around a dining table?
Leave 90cm between the table edge and any wall or furniture on sides where people sit. The minimum on a side nobody walks behind is 75cm. Where people pass behind seated diners, or near a kitchen island or oven, allow 100 to 120cm.
How much space does each person need at a dining table?
Allow 60cm of table edge per person with standard dining chairs. Armchairs and carvers need around 70cm. At 50cm per person you can fit extra guests for an occasion, but it is too tight for everyday meals. Benches give more flexibility because people can shuffle up.
Is 60cm wide enough for a dining table?
Not for people sitting opposite each other. A 60cm-wide table works for seating along one side, against a wall or as a breakfast bar, but two place settings facing each other need at least 80cm. For serving dishes down the middle as well, aim for 90 to 100cm.
What is the standard height of a dining table?
Dining tables in the UK are usually 74 to 76cm high, designed for chairs with a seat height of 45 to 47cm. That leaves around 28 to 30cm between the seat and the tabletop. Check the clearance under the apron or frame rather than the top itself, especially with thicker tabletops and chairs with arms.
