How many guests fit at a round table?

Short answer, because this is usually all anyone wants:

The 6ft round seating ten is the banqueting standard almost everywhere, and it is what a venue will quote you unless you ask otherwise.

How much space does each guest actually need?

The number that matters is table edge per person, not table area. Divide the circumference by the number of seats:

• 75cm each — generous. Room for a full place setting, a wine glass you are not guarding, and elbows.
• 60cm each — standard. This is what "comfortable" means in the table above and what caterers plan for.
• 50cm each — tight. Workable for a drinks-and-canapés seating, uncomfortable for three courses.
• Below 50cm — guests are touching. Somebody will spend the evening with their chair pushed back.

A 6ft round has a circumference of about 574cm. At ten guests that is 57cm each — just under standard, which is why ten at a 6ft is the number everyone lands on and nobody complains about.

Does adding one more seat really matter?

More than people expect. Going from ten to eleven on a 6ft round drops each guest from 57cm to 52cm. That is the difference between reaching for your glass and apologising for reaching for your glass.

If you are one seat over, it is almost always better to add a table than to squeeze every existing one. A room of eleven-seat tables feels crowded everywhere; a room with one extra table feels normal.

How many tables fit in the room?

Do not measure the tables. Measure the tables plus the space around them, which is the mistake that makes a room feel packed when the arithmetic said it was fine.

Per 6ft round, allow a footprint of roughly 3m × 3m. That covers the table, chairs pulled out, and enough room for someone to walk behind a seated guest without asking them to move.

• 1.5m between table edges is the minimum for a service aisle.
• 2m if staff are serving plated courses to both tables.
• 1.2m clear around the perimeter of the room, more if it is a fire route.

Then subtract the dance floor, the band, the bar, the cake table and the gift table before you start placing anything. Those go in first, not last, because they cannot move and tables can.

Round or long tables?

Rounds are better for conversation — everyone can see everyone, and nobody is stranded at an end. Long tables seat more people per square metre and photograph better. Most rooms end up with a mix: long tables where the room is narrow, rounds where it is wide.

One thing worth knowing: on a round table of ten, a guest can comfortably talk to about four people all evening. On a long table they can talk to three. If you are seating someone who knows nobody, a round gives them a better night.
