How long a table can seat 30 people?

The length of a table that can seat 30 people typically depends on the type of seating arrangement. For a rectangular table, a general guideline is to allow 2 feet of space per person on each side, which would require a table length of approximately 20 feet. Alternatively, if using round tables, you might use multiple tables, with each round table seating about 8-10 people. In that case, you would need 3-4 round tables to accommodate 30 people.
