Formula and Assumptions

The recommended capacity is calculated using the following formula:

Recommended Capacity = (Venue Size ÷ 10) × Ventilation Factor

Where:

Venue Size is in square feet
Ventilation Factor is 1.2 for good ventilation, 1.0 for average ventilation

This formula is based on Ontario's public health guidelines which recommend a maximum of 10 square feet per person for indoor gatherings with good ventilation.

Note: Outdoor gatherings typically have higher capacity limits. Always follow local public health orders.

Worked Examples

Example 1: Small Indoor Venue

For a 500 square foot indoor venue with good ventilation:

Venue Size = 500 sq ft
Ventilation Factor = 1.2
Calculation: (500 ÷ 10) × 1.2 = 60 people

The recommended capacity is 60 people.

Example 2: Outdoor Event

For a 1,000 square foot outdoor venue:

Venue Size = 1,000 sq ft
Ventilation Factor = 1.0 (outdoor events typically have good natural ventilation)
Calculation: (1,000 ÷ 10) × 1.0 = 100 people

The recommended capacity is 100 people.
