THE SHORT ANSWER

Room minus 72 in Take 72 in off each room dimension, which leaves 36 in behind the chairs on every side, and what’s left is your largest table. A 10×12 dining area fits up to a 72 in-long table, which seats 6. If no one ever passes behind the chairs, 32 in a side is the minimum.

36 into edge past a seated diner
44 into walk behind the chairs
24 inof table edge per person

Plan for the chairs, not just the table. A diner pushed back from the table takes up the space between the table edge and the wall, and anyone who needs to get past needs more. The National Kitchen & Bath Association (NKBA) publishes those distances, and the calculator above applies them to your room.

Rectangular tables are usually 36 to 40 in wide (Bassett). Each diner needs about 24 in of table edge (IKEA, Pottery Barn).

For a dining corner in a living room, measure to the edge of the walkway or the back of the sofa instead of a wall. Our guide to a dining table in a small living room walks through the layouts.

  • The dining area, wall to wall or to the edge of the walkway.
  • Anything that sticks out: radiators, a sideboard, a door swing.
  • Whether people walk behind the chairs to reach the kitchen or a door.
  • Your chairs: armchairs need more than 24 in of table edge each.

Questions

How much space do you need around a dining table?

At least 36 in from the table edge to the wall so people can edge past seated diners, and 44 in to walk behind them. 32 in works only if no one ever passes.

What size table fits a 10×10 dining room?

With 36 in on every side, up to a 48 × 48 in table or a 48 in round. Either seats 4; the round can squeeze in 6.

How many people fit at a 6-foot table?

Six: West Elm sizes tables 60 to 72 in long for six. Along a 72 in side, that’s three diners at 24 in each.

Is a round table better in a small room?

In a square room, a round table seats about the same number as a square one of the same size, and its curved edge leaves a little more space at the corners for passing.
