How the Round Table Seating Calculator works
Seats per table = the table circumference ÷ the edge space each guest needs, rounded down. The circumference is π × diameter, and about 22 inches of edge per guest is comfortable, while 18 inches is tight and 24 inches is roomy. Tables needed = guests ÷ seats per table, rounded up. Each table also needs room for pulled-out chairs and a walkway, so the footprint diameter is the table diameter plus the clearance on both sides, and the floor area is π ÷ 4 × the footprint squared. Check the number against your venue and fire code rules, which may set a lower limit. Example: with Table diameter 60 in, Edge space per guest 22 in, Chair and walkway clearance around the table 36 in, and Guests to seat 120, the result is Seats per table = 8; Tables needed = 15; Empty seats = 0.
