“You just want to be sure the leg space isn’t being invaded by the supports,” said Jackie Hirschhaut, the vice president of public relations and marketing for the American Home Furnishings Alliance. The base - usually legs, a pedestal, or a trestle - can have an effect on how many people you can fit at a table. “Figure that each place at the table needs 22 to 24 inches of table space and that larger-scale chairs will require more,” said Max Dyer, a furniture industry veteran and a current vice president of casegoods (a category of hard furniture like tables, cabinets, and chairs) at La-Z-Boy Industries. Next, think about how you’re going to use the table. Then subtract about six feet from those two measurements to get a target dining table length and width.

So whether it’s part of a multiuse space or a separate dining room, start by measuring the length and width of the area you can dedicate to the dining table. “In addition to the footprint of the table, you’ll want three feet of breathing room on all sides - and more is better - to comfortably sit in a chair and move around the space,” said Lucy Harris, an interior designer in New York. The number one rule: Your dining table has to fit your dining area! But a dining table is a deceptively large piece of furniture, and you need to account for space around it, too.
