Dining table sizes — how many people actually fit, and the clearance behind every chair

The rule everything follows

Every diner needs 24 inches of table edge — elbows included. A 72-inch table seats six only if nobody sits the ends; the same table with end seats is an eight at Thanksgiving and a six every other night. Width matters too: under 36″ across, facing place-settings start to interleave.

Rectangular tables

Length × width	Seats	Notes
48 × 36	4	two per side
60 × 36	4–6	6 means end seats
72 × 36	6	the family default
84 × 40	6–8
96 × 42	8–10
108 × 44	10
120 × 46	10–12	check your room first

Extension tables: verify BOTH states — closed for every day, open for the one day that justifies it.

Round tables

Round tables seat more per square foot of table — and need more room around them, because every seat pulls back.

Diameter	Seats	Notes
36″	2	breakfast for two
42″	2–4
48″	4	the comfortable four
54″	6	six is snug
60″	6–8	the conversation size
72″	8–10	rare for a reason — reach

The space behind the chairs

pullback is the real footprint of a dining table

Chair pullback: 36″ from table edge to the nearest wall or piece — enough to sit down and stand up.
Walk-behind: 42–48″ where a path runs behind seated diners.
Buffet or sideboard (typ. 60 × 18): give its front 30″ of working room — and remember it faces the pullback zone.
Rug under the table: chairs should stay on it pulled out — table length + roughly 24″ per side. A 72″ table wants an 8 × 10.
Counter & bar stools: 21–24″ of run per stool.

Now place it on your plan.

Upload your builder's plan, set the scale, and drop a 72-inch table into your actual dining room — Poché draws the pullback halo and warns you the moment the walk-behind pinches.
