How should I estimate attendee numbers for a new event?

Estimating attendance for a first-time event

Estimating attendance for a new event is a mix of research, comparable benchmarks, and conservative planning. Use multiple data points to create low/medium/high scenarios and plan logistics for the medium estimate.

Steps to estimate:

  • Research similar local events and analyze their reported attendance.
  • Survey your target audience via email, social media, or partner lists to gauge interest.
  • Start with conservative conversion rates: of those who express interest, expect 20–40% to register and 60–80% of registrants to attend.
  • Consider seasonality, competing events, and marketing reach when adjusting projections.

Create projection tiers:

  • Conservative: 50–60% of maximum expected sign-ups
  • Target: realistic number based on marketing plan and partnerships
  • Optimistic: high-response scenario for scaling needs

Operational tips:

  • Plan venue and catering for the target estimate, with scalable options (additional seating or food pickups).
  • Monitor registrations and adjust marketing intensity to hit goals.
  • Use early-bird incentives and limited ticket batches to create urgency and better forecasting.

Estimating is iterative—track registration patterns weekly and refine projections. For first-time events, prioritize flexibility and contingency so you can scale up or down without major cost penalties.
