Dining table size guide: dimensions for 4, 6, 8 and more

The rules behind every dining table size

Dining table sizing rests on three numbers. Use them and you can size a table for any room and any number of people.

• 24 in per diner. Each person needs about 24 in (61 cm) of table edge to eat without bumping elbows. 28 to 30 in is more comfortable, and armchairs at the table often need 30 in or more.
• 12 to 15 in of depth per place setting. Each side needs room for a plate, glass and cutlery, and the middle needs room for serving dishes. That's why most dining tables are 36 to 40 in wide; below about 30 in, two people facing each other run out of space.
• 36 in of clearance. Leave at least 36 in (91 cm) from the table edge to a wall or other furniture so chairs can be pulled out and people can sit down. Where people need to walk behind seated diners, allow 42 to 48 in (107 to 122 cm).

Table legs and bases change these numbers in practice. A leg at each corner of a rectangular table takes away a seat position at each end in some designs; a trestle or pedestal base frees up knee room and lets you squeeze in an extra chair more easily.

Dining table size by number of seats

These are typical dimensions for comfortable seating. Exact sizes vary by design, so check the maker's stated seating capacity and look at where the legs sit.

For six, a 72 in rectangle seats three per side at 24 in each, with nobody at the ends; a 78 to 84 in table seats two per side plus one at each end more comfortably. Round tables get unwieldy above about 72 in: people across the table are too far away to talk to and too far to reach the center.

Round, rectangular or oval

Rectangular

The most flexible shape. It fits long, narrow rooms, scales to any number of people and is the most common shape for extending tables. Its weakness is the ends: people at the far corners can feel cut off from the conversation at a long table.

Round

Round tables are the most sociable for four to six: everyone can see everyone, and there are no corners to bump. They suit square rooms and breakfast nooks, and they take up less floor than you would expect because the corners of the room stay open. A pedestal base helps most here, since there are no legs to work around. The walnut Desco is a round pedestal table built on this principle.

Oval

Ovals take the length of a rectangle with softer ends. They're easier to walk around in tight rooms and slightly easier to squeeze an extra chair onto, because the rounded ends have no corners.

Square

Square tables seat four well at 36 to 44 in a side. Larger squares seat eight but get deep: at 60 in, the center is hard to reach.

Clearance and room size

Measure the room first, then work backwards. Subtract the clearance you need on each side and what's left is the largest table that fits.

• 36 in (91 cm): the practical minimum from table edge to wall where nobody needs to walk behind seated diners.
• 42 to 48 in (107 to 122 cm): where people walk behind chairs to reach a kitchen, door or the other side of the table.
• Up to 60 in: next to a sideboard or cabinet whose doors or drawers open into the space.

Room dimensions are rounded up to the nearest half foot. In open-plan spaces, measure the clearance to the nearest obstacle, such as a kitchen island or sofa back, rather than to a wall. The rug under the table needs room too; see our rug size guide.

Height: table, chair and the 12-inch gap

Standard dining table height is typically 28 to 30 in (71 to 76 cm) from floor to tabletop. Dining chair seats are typically 17 to 19 in high. The important number is the difference: about 12 in (roughly 10 to 13 in works) between seat and tabletop gives room for your legs and puts the table at a comfortable height for eating.

• Apron clearance: many tables have an apron, a frame under the top. Check the distance from the floor to the underside of the apron; you want around 24 to 25 in, or at least 7 in above the chair seat, so thighs fit underneath.
• Armchairs: check that the chair arms slide under the tabletop or apron, otherwise the chair can't be pulled in.
• Counter and bar height: counter-height tables are typically 34 to 36 in and take stools with 24 to 26 in seats; bar-height tables are typically 40 to 42 in and take stools with 28 to 30 in seats. The same roughly 10 to 12 in gap applies.

Chair width is the other variable. Dining chairs are typically 18 to 22 in wide, so in 24 in of table edge there's a few inches of space between chairs. Wider upholstered chairs, such as the Sella, deserve the more generous 28 to 30 in spacing. Browse all dining chairs.

Extending tables

If you seat four most days and eight or ten a few times a year, an extending table is the answer. Size it in two ways:

1. Closed size should suit daily use and the room with full clearance.
2. Extended size should fit the room with at least the 36 in minimum, even if you accept less clearance on the few nights it is fully open.

Extensions come as removable leaves, stored separately; butterfly or self-storing leaves that fold inside the table; and pull-out ends. Self-storing leaves are the easiest to use often. Check where the legs end up when extended: on some designs, extending puts a leg mid-seat on the long side.

The oak Tavolata extends to seat from 4 to 10, which covers the range most households need. See all dining tables or the Editions dining collection.

How to choose: a quick checklist

1. Count how many people you seat on a normal day and on a full day.
2. Measure the room, then subtract 36 in on each side (42 to 48 in on sides where people walk).
3. Pick a shape that suits the room: round or square for square rooms, rectangle or oval for long ones.
4. Check the base: legs, trestle or pedestal, and where seats fall in relation to them.
5. Check height: about 12 in between chair seat and tabletop, with room under the apron.
6. Tape the outline on the floor, chairs pulled out, and walk around it.

A table that fits on paper can still feel crowded once chairs are out, so the tape test is worth doing. For help planning the room, our interior design service can work with your floor plan.
