Enter your number of guests and preferred table type (rectangular or round) to find out how many tables you need and what size works best. You can also flip it around — input a table length or radius to see how many people it seats. Results include tables needed, seats per table, and a full breakdown by common table sizes.

Divide your total guest count by the number of seats per table. For example, 100 guests using 60-inch round tables (8 seats each) requires 13 tables. Always round up and consider adding 1–2 extra tables as a buffer for last-minute RSVPs or special seating needs. See also our Generator Wattage Calculator.
A 60-inch (5-foot) round table typically seats 8 people comfortably, or up to 10 if seating is tight. This is the most common round table size for weddings and banquets.
An 8-foot (96-inch) rectangular table seats 8 people along its long sides — 4 per side — using standard 24-inch spacing. If you add seats at both short ends, it can seat up to 10 people.
The standard allowance is about 24 inches (60 cm) of table length per person for comfortable seating. For tighter setups (such as banquets), 18–20 inches is sometimes used, while more formal or comfortable arrangements may use 28–30 inches. You might also find our Microwave Wattage Converter useful.
A 6-foot (72-inch) rectangular table seats 6 people comfortably (3 per side), or up to 8 if you include end seats. It's a popular choice for smaller events and classroom-style setups.
Room capacity depends on your square footage and table layout. A common rule of thumb is 10–12 square feet per person. Subtract areas used for dance floors, stages, or service stations before calculating. A 60-inch round table with chairs typically needs about 64–78 square feet of floor space.
A 72-inch (6-foot) round table comfortably seats 10 people. It requires more floor space than a 60-inch table, so ensure your venue has adequate room — typically around 90–100 square feet per table including chair clearance.
Round tables encourage conversation among all guests and are popular for weddings and galas. Rectangular tables are better for banquets, long head tables, or classroom/conference-style layouts. Rectangular tables also make more efficient use of space in some room shapes.
