How a Crowd Crush Happens — And Why Capacity Numbers Are Not Bureaucracy

Every time a concert is stopped for "overcrowding," someone online says the organisers were being dramatic. They were not. Crowd danger is not about how many people are in a field — it is about how many people are in one square metre, and how fast they can leave it.

• Up to ~2 people per m²: free movement. Comfortable.
• ~4 per m²: shoulder contact, movement slows.
• ~5–6 per m²: you no longer choose where you go; the crowd carries you.
• Beyond that: pressure waves travel through bodies. People are injured standing up, not trampled on the floor.

A licensed capacity is the number where exits, stewards, medics and open ground still work together. Cross it and every one of those margins shrinks at the same time.

1. One gate for everyone. A single entry point turns a patient queue into a wedge.
2. Everyone arrives at once. No support acts, one headliner, one arrival spike.
3. Ticket integrity fails. Screenshots, duplicates and jumped fences mean the real count is unknown.
4. No live counting. If nobody knows the number inside, nobody can decide to stop.
5. No hold plan. Stopping entry is a decision that must be pre-agreed, or it is made too late.

Timed entry slots. Multiple separated gates with scanners that reject duplicates. Stewards facing the crowd, not the stage. A control room with a live count and the authority to pause. Wide lateral escape routes, not just a back exit. And a published statement of what happens to your money if the event stops.

• Keep arms up and folded across your chest to protect your ribs and breathing space.
• Move diagonally with the crowd, never against it.
• Stay on your feet; help others back up immediately.
• Choose your spot before the surge — near a barrier gap, not against a solid fence.
• If you cannot breathe comfortably, leave early. Nobody remembers you left; you will remember you did.
