Table Layout Calculator — Tables & Seating Plan
Plan table sizes, quantities, and room layout for your event based on guest numbers.
How We Calculate This
This calculator works out how many tables you need based on guest numbers and table type.
The formula
Tables needed = (guests - top table guests) / seats per table
Floor space is estimated by allowing about 1.5 sqm per seated guest — enough for the table footprint, chair pull-back and a 1.5m service aisle between rows (Expo Hire / NACE guidance). That gives roughly 12 sqm for a 5ft round of 8, 15 sqm for a 6ft round of 10, 9 sqm for a 6ft trestle and 11.5 sqm for an 8ft trestle. Choosing a wider service aisle in the advanced options increases the floor space proportionally.
