In a place that may remain open to the public, 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).
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.
The rule is based on the total number of people in the space – including staff – and is limited to a maximum of 100 people gathering in the same, undivided indoor space.
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 = 87.45
- Maximum number of people = 21
