A six chair dining table is usually between 150cm and 180cm long. A 150cm table seats six with two people on each long side and one at each end, while a 180cm table seats three along each side comfortably. For six people all seated around the sides and ends with generous elbow room, 165cm to 180cm is the more relaxed choice. Round tables seating six typically measure 130cm to 150cm in diameter.
Those figures come from a simple rule: allow 60cm of table edge per person. Anything less and diners touch elbows. Anything over 70cm each and conversation across the table starts to feel stretched.
Take the perimeter of the table and divide it by 60cm to find the realistic number of seats. On a 160cm by 90cm rectangle, each long side offers two comfortable places or three at a squeeze, and each end offers one.
That gives six around the sides and ends without difficulty. If you never use the ends, because the table sits against a wall or a radiator blocks one end, you need the full 180cm to fit three people along each side.
Table width matters too. A rectangular dining table should be at least 80cm wide so that two place settings can face each other with serving dishes down the middle. At 90cm to 100cm the table feels genuinely generous.
Rectangular tables are the most space efficient in a typical UK dining room, which is usually longer than it is wide. They also sit neatly against a wall when not in use.
Round tables seating six need a diameter of around 130cm to 150cm. They suit square rooms and encourage conversation because everyone can see everyone. The trade off is the floor space needed around them, since a round table cannot be pushed into a corner.
Oval tables offer a middle path: the length of a rectangle with softer corners that ease circulation in a narrow room. A 170cm oval seats six with less visual bulk than the equivalent rectangle. The modern dining tables UK sale range covers all three shapes, which helps when you are weighing the options against a specific room.
The table is only part of the calculation. Allow 90cm to 110cm between the table edge and the nearest wall or furniture so chairs can be pulled out and people can pass behind seated diners.
That means a 160cm table needs a room at least 340cm long to work comfortably, and around 280cm wide for a 90cm table with clearance on both sides. Measure the room and subtract the clearance before deciding on a table length rather than the other way round.
Where the room will not allow full clearance, position the table so the tight side faces a wall and use a bench there. A bench slides fully under the table and needs no space behind it.
Many UK homes need a table that seats four most days and six or eight occasionally. Extending tables solve this neatly, typically opening from 120cm to 160cm, or 160cm to 200cm, using a butterfly leaf stored inside the table itself.
Check how the mechanism works before buying. Some require the leaf to be stored separately, which is only practical if you have somewhere to keep it. Self storing leaves are more convenient but add a little depth under the tabletop, which reduces chair clearance slightly.
Also consider how often you will actually extend it. A table left permanently open is really just a large table, so measure the extended length against your room as the primary figure. The extending dining tables UK sale range shows the typical open and closed dimensions across different styles.
Standard dining table height in the UK is around 75cm. Paired with chairs at 45cm to 47cm seat height, that gives the 28cm or so of thigh clearance that most people find comfortable.
Watch for aprons and rails under the tabletop. A deep apron reduces the usable clearance and can stop upholstered chairs tucking in. Pedestal and trestle bases avoid the problem at the corners, which is why they often seat one more person than a four legged table of the same length.
If you are buying chairs at the same time, check arm height too. Carver chairs need the arms to pass under the table edge or they will sit permanently proud. The dining chairs UK sale range lists both seat and arm heights, which makes the check straightforward.
Two tables of identical length can feel very different. A solid wooden table with thick legs reads heavy and fills a room visually. A glass topped table of the same size almost disappears, which is useful in a compact space.
Marble and stone tops sit between the two: substantial to look at but often paired with slim metal bases that keep the floor visible. High gloss finishes reflect light and can make a room feel larger, though they show fingerprints more readily.
In a small dining room, choosing a lighter looking table often lets you go longer than you expected. A 170cm glass table can feel less imposing than a 150cm farmhouse table in the same space, and the glass dining tables UK sale options are worth considering where space is tight.
Mark the table footprint on the floor with masking tape before ordering. Put the chairs you already own inside the outline and sit on them. It takes ten minutes and is the single most reliable way to test whether a length works.
If you would rather remove the guesswork entirely, buying a table and chairs together guarantees the proportions are right. The 6 seater wooden dining table sets UK collection is designed around exactly these dimensions, so the clearance and spacing questions are already answered.

Many households hesitate between a table for six and one for eight, and the honest answer usually depends on how often the extra places are genuinely used.
A permanent eight seater needs around 200cm of length and a room of at least 380cm to allow proper clearance. If that space exists and gatherings are frequent, the larger table earns its place and looks better than a small one adrift in a big room.
Where the extra seats are needed only a few times a year, an extending table is the more sensible choice. Living with a 160cm table for most of the year and opening it to 200cm at Christmas is far more comfortable than squeezing past an oversized table every day.
Consider also how the room is used between meals. A table that doubles as a desk or homework space benefits from extra length, whereas one in a busy kitchen route does not.
The number of chairs stored is a factor too. Two spare chairs need somewhere to live, and stacking or folding designs solve this neatly. A bench is the other answer, seating two or three when needed and sliding fully out of sight the rest of the time.
Two tables of the same length can seat different numbers of people depending on what holds them up. A four legged table places a leg near each corner, which frequently prevents a chair sitting in that position and reduces the practical capacity.
Pedestal and trestle bases free the corners entirely, so a 150cm pedestal table often seats six where the same length on legs seats four comfortably. In a room where every centimetre counts, that difference is worth more than an extra 20cm of length.
Check the position of any cross rail as well. A stretcher running between the legs at ankle height is attractive but limits where people can put their feet, which becomes noticeable during a long meal.
Between 150cm and 180cm. A 150cm table seats six using both ends, while 180cm allows three people along each long side.
At least 80cm so that place settings can face each other with room for serving dishes. Between 90cm and 100cm feels more generous.
A diameter of 130cm to 150cm. Below 130cm the place settings start to overlap towards the centre of the table.
Allow 90cm to 110cm from the table edge to the nearest wall on every side people use, so chairs can be pulled out and diners can pass behind.
Yes, if you usually seat four. Measure the extended length against your room first, since that is the dimension that decides whether the table works when it matters.
