Dining Table Sizes: A Complete Guide by Number of Diners and Shapes

Updated in October 2026

Quick answer: Allow about 60 cm of table edge per guest. For a round table: 100 to 110 cm in diameter for 4 people, 140 cm for 6, and 180 cm for 8. For a rectangular table: 80 x 120 to 140 cm for 4 people, 90 x 180 cm for 6, and 100 x 240 cm for 8. The ideal width is between 80 and 100 cm, and the standard height of a dining table is 75 cm.

Choosing a dining table starts with a specific question: how many people sit at it every day, and how many during special meals? From there, the dimensions are no longer a matter of taste but become a matter of centimeter calculations.

In this guide, you'll find dining table dimensions based on the number of people for round, square, rectangular, and oval tables, as well as the recommended width and standard height. If you want to calculate the space needed for the entire room, including chairs and walkways, check out our guide to dining room dimensions.

Summary

  • Rule of thumb: 60 cm of table edge per guest; 70 cm for a little extra space.
  • Round: 100 to 110 cm for 4, 140 cm for 6, 180 cm for 8.
  • Rectangular: 80 x 120 to 140 cm for 4 people, 90 x 180 cm for 6 people, 100 x 240 cm for 8 people, 100 x 280 cm for 10 to 12 people.
  • Recommended width: 80 to 100 cm. If it's less than 70 cm, it's hard to eat facing each other.
  • Standard height: 75 cm, with seats at 45 or 47 cm.

The 60-cm-per-diner rule

Each person needs about 60 cm of table space on the side to eat without bumping elbows, and about 35 to 40 cm of depth for a plate, glass, and cutlery. When diners are seated across from each other, that depth doubles; that’s why dining tables are typically 80 to 100 cm wide.

With this rule, you can estimate the capacity of any table in seconds: divide the usable perimeter by 60, and you'll get its actual capacity. For a one-time celebration, you can lower this to 50 cm per person, which explains the ranges listed for the tables' maximum capacity.

Dimensions of a round dining table

The round table is the most sociable: everyone can see each other, and there’s no designated chairperson. However, it requires open space on all sides. It works especially well in square dining rooms and for groups of 4 to 6 people.

Diameter Comfortable diners Maximum capacity
100 cm 4 4
110 to 120 cm 4 6
140 cm 6 7
150 cm 6 8
180 cm 8 10

For 10 people to sit comfortably around a round table, it would need to be over 200 cm in diameter—a size that’s impractical for a home. Beyond that, rectangular or oval tables make better use of the space. An extendable round table solves the problem: round for everyday use and oval when guests come over.

Dimensions of a square dining table

A square table fits well in symmetrical spaces and can be pushed up against a wall or into a corner when not in full use. It's a great choice for small dining rooms and open-concept kitchens.

Side Diners
75 to 80 cm 2
90 to 100 cm 4
120 to 130 cm 4 people comfortably, up to 8 if cramped
150 cm 8

If the table is longer than 150 cm, the center of a square table will be out of reach for diners. For large groups, it's better to choose an extendable square table that can be lengthened into a rectangular shape.

Dimensions of a rectangular or oval table

The rectangular shape is the most efficient per square meter and the one that scales best when guests arrive: there’s always room for one more at the ends. The oval shape has the same dimensions, softens the corners, and provides a little more walking space in narrow dining rooms.

Width x Length Diners
80 x 120 to 140 cm 4
80 x 160 cm 4 to 6
90 x 180 cm 6 to 8 on time
100 x 200 to 220 cm 8
100 x 240 cm 8 to 10
100 x 280 cm 10 to 12

Dining table width: 70, 80, 90, or 100 cm

The width determines whether the plates and centerpieces will fit and whether there will be enough space around them. Here are the measurements:

Width What is it used for?
70 cm Just enough space to sit across from each other. Useful in narrow dining rooms with no room for a centerpiece.
80 cm The standard size for 4 to 6 people. A balance between comfort and space.
90 cm Seats 6 to 8 people comfortably, with room for serving dishes and a centerpiece.
100 cm or more Long tables measuring 200 cm or more, so they don't look too narrow.

If your dining room is long and narrow, a table that is 80 cm wide and 160 to 180 cm long is usually the best solution: it leaves room to walk on either side without sacrificing seating.

Standard height of a dining table

The standard height of a dining table is 75 cm (about 29.5 inches), with a typical range of 72 to 76 cm. It is designed for chairs with seats 45 or 47 cm above the floor: this 28- to 30-cm difference between the seat and the tabletop allows you to eat with your arms in a natural position.

Type Table height Seat Height
Dining table 72 to 76 cm 45 to 47 cm
Low dining table 65 to 70 cm 40 to 43 cm
High table or bar table 90 to 110 cm 65 to 80 cm

Before pairing a table with chairs you already own, measure the heights of both and make sure the difference is between 28 and 30 cm. If you’re using chairs with armrests, also check that the armrests fit under the tabletop. In our article on the best wooden dining chairs, we list the heights of each model.

And the space around the table

In addition to the table's dimensions, you'll need about 75 cm of clearance on each side for chairs and 90 to 100 cm in walkways. If the result doesn't fit in your dining room, go down a size or choose a different shape rather than sacrificing walkway space. The complete calculation based on the number of people is in the dining room measurement guide linked at the beginning.

And if there are usually 4 of you but you have 8 guests several times a year, don't buy the 8-person table—buy the 4-person one that converts to an 8-person table. Extendable solid-wood tables can be extended by 40 to 90 cm when needed.

Frequently Asked Questions

What size table do I need for 6 people?

For a round table, 140 cm in diameter is a comfortable size for 6 people; at 120 cm, it’s a bit tight. For a rectangular table, 80 x 160 cm seats 6 people, and 90 x 180 cm provides plenty of room, with enough space for 8 on rare occasions.

How big is a dining table for 4 people?

A rectangular table measuring 80 x 120 to 140 cm, a square table with sides measuring 90 to 100 cm, or a round table with a diameter of 100 to 110 cm.

What should be the diameter of a round table for 8 people?

For 8 people to sit comfortably, 180 cm. A 150-cm table seats 8 in a tight arrangement, which is acceptable for a celebration but uncomfortable as an everyday setup.

And what are the dimensions for a table that seats 10 people?

Whether rectangular or oval, 100 x 240 cm is the standard size for 10 people, and 100 x 280 cm if you want a little extra room. For a round table, it would need to be over 200 cm in diameter.

What is the ideal width for a dining table?

Between 80 and 100 cm. An 80-cm table comfortably seats 4 to 6 people; a 90- to 100-cm table leaves room for platters in the center. At less than 70 cm, it’s difficult to eat facing each other.
