Seating chart for 400 guests at 6-ft rectangle tables: how many tables you need

400 guests is ballroom territory. 6-ft rectangle tables at 6 seats each work out to 67 tables, which means the venue's own floor plan, the room's posted capacity, and the caterer's service plan all shape where tables go before a single name is placed. Rectangles fit more people in a smaller footprint than rounds do, which matters once you're placing 400 guests. Just plan on the two ends of each table feeling slightly more removed from the middle.

Room size for 67 6-ft rectangles

Each 6-ft rectangle table needs about 7×8 ft: a 6-ft banquet table plus chairs along both long sides and walking room at the ends. That's roughly 3,752 sq ft for tables alone across 67 tables. Add space for a dance floor, bar, gift and cake tables, and walking paths, and plan on about 4,052–4,552 sq ft of total reception space, depending on how much of the room is dedicated to dancing versus dining.

FAQ

How many 6-ft rectangle tables do I need for 400 guests?

67 tables. That's 400 guests ÷ 6 seats per table = 66.7, rounded up to a whole table. You round up, not down, because a table can run under capacity but can't seat a fraction of a guest.

How much room do 67 6-ft rectangles take up?

Tables alone take about 3,752 sq ft (67 tables at roughly 7×8 ft each, a 6-ft banquet table plus chairs along both long sides and walking room at the ends). Add a dance floor, bar, gift and cake tables, and walking paths, and plan on roughly 4,052–4,552 sq ft of total reception space.

What if my guest count changes before the wedding?

Don't rebuild the chart for every RSVP. If about 10% don't show, 400 guests only actually needs 60 tables; if about 10% bring an unlisted plus-one, plan for 74. Wait until two weeks after your RSVP deadline to finalize, and leave a seat or two open at several tables rather than reworking the whole layout each time a guest count shifts.
