A 6 seater dining table is 72 inches long and 36 inches wide (6 × 3 feet, 180 × 90 cm), with three chairs a side, or two a side and one at each end. The table itself is easy to place; the chairs are what take the room. Pulled out with someone sitting, each chair needs 24 inches behind the table edge, and a person needs to pass behind that. So:

In a 9 × 9 foot dining space, put one long side against the wall and use the table as a 4-seater on weekdays, pulling it out for six.
Shapes
Rectangle, 72 × 36: the standard, fits along a wall, seats six without elbows touching.
Rectangle, 60 × 36: sold as a six-seater, really a comfortable four; six adults touch elbows.
Round, 54 to 60 inches across: seats six, everyone sees everyone, needs a square room of 10 × 10.
Bench on one side: three people on a bench that slides under the table, which saves 18 inches of floor.
What a 6 seater dining set should have
Table height 30 inches (75 cm) and chair seat height 18 inches: the pair that works.
Top thickness 25 mm or more in solid wood; thinner tops sag in the middle over years.
Legs at the corners, not inset, so the end seats have knee room.
Weight: a solid sheesham 6 seater set is 90 to 130 kg including chairs. A set at 50 kg is not solid wood.
Cushioned seats that unscrew, so the fabric can be changed.
