About Guest Seating Arrangement Calculator

Table count is guests minus the head table divided by seats per table, rounded up. Room area at 1.1-1.3 square metres per guest for a seated dinner covers tables, chairs and circulation — banquet venues quote capacity on roughly this basis.

Formula

Seating

tables = ceil((guests - head table) / seats per table); area = guests x space per guest

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How much space does a seated dinner need?

About 1.1-1.3 m2 per guest with round tables. Add more for a dance floor, buffet stations or a stage.

Round or long tables?

Rounds of eight to ten seat more people in the same area and encourage conversation; long tables look more formal but waste corner space.
