In a place that may remain open to the public, that are not places of residence, occupiers and operators of the premises must not
- allow persons to enter or stay on the premises (whether outdoor or indoor) if the size of the premises is insufficient to allow for 4 square metres of space for each person (the four square metre rule)
- allow 100 or more people to enter and stay on indoor premises at the same time (the 100 person rule), and
- allow 500 or more people to enter and stay on outdoor premises at the same time (the 500 person rule).
These rules do not apply to certain "essential gatherings".
Where the 4 square metre rule applies, the size of the premises has to allow for at least 4 square metres of space per person.
All people on the premises, including staff, must be counted when applying the 4 square metre rule, the 100 person rule, and the 500 person rule.
How to calculate the number of people for the size of your room
- Measure the length of the room.
- Measure the width of the room.
- Multiply the length by the width to calculate the area of your room in square metres.
- Divide the area of your room (calculated in square metres) by 4 to calculate the maximum number of people allowed.
|Number of people||Minimum space required|
|1||4 square metres|
|10||40 square metres|
|20||80 square metres|
|30||120 square metres|
|40||160 square metres|
|50||200 square metres|
|60||240 square metres|
|70||280 square metres|
|80||320 square metres|
|90||360 square metres|
|100||400 square metres|
- Length = 8.25 metres
- Width = 10.6 metres
- Square metres: 8.25 x 10.6 = 87.45
- Maximum number of people: 87.45 ÷ 4 = 21
