How many security guards do I need for an event?

Why ratios mislead

A guest-to-guard ratio treats a seated dinner for three hundred and a standing concert for three hundred as the same event. They are not. The count comes from the posts an event actually needs at the same moment, and the posts come from the layout and the plan. Walk the venue and ask: how many doors must be controlled, how big is the floor and how far can one officer see, is there a lot, is there cash, is there alcohol, and what happens at the end when everyone leaves at once.

The posts, one by one

Entrances: one officer per controlled door for the arrival window, checking tickets, lists or bags as the plan says; a second where the line is long. The floor: one roving officer for a calm event of a few hundred, more where alcohol is served, the crowd is young or the space is broken into rooms. The lot: one officer where parking is on site and unattended cars are the risk. Cash: one officer with the box and the route to the safe. The end: everyone on the floor moves to the exits and the lot for the last half hour.

What moves the number up

Alcohol, especially with a bar rather than served wine. Crowds under thirty. Rival groups, a contentious subject or a public figure. Outdoor venues with a long perimeter. Late finishes. Events where the host expects uninvited guests. Any of those adds a post; several of them add a lead officer to run the team.

What moves it down

A seated format, a guest list, a single entrance, a venue with its own staff at the doors, daylight and an early finish. A church banquet with one door and no bar can be one officer at the door and the lot.
