Event staffing calculator

How many stewards, security and first aiders does your event need? Get starting-point numbers from your attendance and risk level.

← All tools

Planning aid based on recognised crowd-safety guidance — not a substitute for a professional crowd risk assessment, formal egress calculation, or local regulations.

How it works

We start from common steward-to-attendee ratios — often around 1:100 for lower-risk crowds, tightening as density, alcohol, standing audiences and late-night events raise the risk — then add suggested security and first-aid cover scaled to your numbers.

Why it matters

Too few trained staff is a recurring factor in crowd incidents: no one to spot a building crush, open a relief exit, or start first aid in the minutes that matter most. Right-sizing your team before the event is far cheaper than discovering the gap on the night.

Good practice
  • Brief every steward on their position, the evacuation plan and how to escalate.
  • Add cover for alcohol, standing crowds, headline acts and entry/exit surges.
  • Keep first-aiders reachable and their locations known to all staff.
