Round or rectangular table? Seat the guests and see

A table that "seats six" can still leave your elbows colliding. What decides it is how much table edge each person gets, and the shape of the table changes that a lot.

Pick round or rectangular, enter your table's size and slide the edge-per-person figure to see where the chairs go, how many seats fit, and how much floor the whole set needs. Includes what to measure before you buy and cheaper ways to seat extra guests.
