Venue capacity

Capacity looks like a single number in the venue brochure, but it's really a calculation that moves with your build. The licensed figure assumes an empty hall; fill it with booths, stages, and catering and the usable occupancy drops, because capacity is driven by egress — how fast people can get out — not by square metres. Organizers need the layout-adjusted number early, since it caps how many badges you can sell and how you schedule peak moments like keynotes and prize draws that pull the whole audience into one space. Commercially, capacity discipline protects the event's licence and its insurance; exceed it and an inspector can close the doors at your busiest hour, which is both a safety failure and a refund catastrophe. The common mistake is planning attendance against the brochure figure instead of recalculating after the floor plan is drawn, then discovering the gap when the fire marshal reviews the layout. One honest nuance venues rarely volunteer: registration counts and real-time occupancy are different things. Ten thousand registered doesn't mean ten thousand present at once, so events that track actual in-hall numbers can often admit more total attendees safely — but only if they're genuinely measuring, not guessing.
