The number of canteen seats required is not always equal to the total number of employees, students or visitors.

The calculation should be based on peak users, meal shifts, available floor space and the amount of time each group spends in the dining area.

Step 1: Estimate peak users

Identify the busiest meal or break period.

For example, a factory with 300 employees may not need 300 seats when workers eat in several scheduled shifts. A school may require a different calculation when multiple year groups share the same canteen.

Step 2: Identify the seating turnover

Estimate how long each group occupies the tables. Faster turnover may reduce the total number of seats required, provided the schedule is realistic.

Avoid planning a layout that depends on users leaving immediately.

Step 3: Measure usable floor space

Remove areas occupied by:

• Food counters
• Tray-return stations
• Wash areas
• Pillars
• Doors
• Storage
• Main walkways
• Emergency routes

The remaining area is the usable seating zone.

Step 4: Choose a mixture of capacities

Fibreglass canteen furniture is available in several seating configurations, including 2, 4, 5, 6 and 8-seater sets.

A mixed layout can serve individuals, small groups and larger groups more effectively than using one identical table throughout the facility.

Should every table be fully occupied?

No. Real canteen usage is rarely perfectly efficient. Some users prefer additional personal space, while bags or trays may occupy nearby seats.

Include a reasonable operational buffer when calculating capacity.

What else affects the furniture quantity?

Consider:

• Accessibility requirements
• Cleaning routes
• Queue positions
• Shift changes
• Group behaviour
• Future workforce or enrolment growth
• Replacement or spare units

A good canteen layout balances seating capacity with safe and practical movement.
