Frequently Asked Questions

Q

How many waiters do I need for a wedding?

For a plated dinner wedding, plan 1 waiter per 10 guests. A 150-guest wedding needs 15 waiters for plated service. Buffet service needs fewer — about 1 per 25 guests (6 total). Add bartenders at 1 per 50 guests and bussers at 1 per 25 guests for a complete team.

  • Plated dinner: 1 waiter per 10 guests (most labor-intensive)
  • Buffet: 1 waiter per 25 guests (refill stations, clear plates)
  • Family style: 1 waiter per 15 guests (bring platters to tables)
  • Food stations: 1 waiter per 30 guests (attendants per station)
  • 150-guest plated wedding = 15 waiters + 3 bartenders + 6 bussers

Q

What is the standard bartender to guest ratio?

The standard ratio is 1 bartender per 50 guests for a full bar. For cocktail-focused events, use 1 per 35 guests. Each bartender can serve approximately 100–120 drinks per hour if the bar is well-stocked and organized. For a 150-guest wedding, hire 3 bartenders.

  • Standard bar: 1 bartender per 50 guests
  • Cocktail event: 1 per 35 guests (drinks are the focus)
  • Beer & wine only: 1 per 60–75 guests
  • Self-serve bar: 1 per 100 guests (just to manage and restock)
Q

What other event staff do I need besides waiters?

A full event staff includes captains (1 per 75–100 guests), bussers (1 per 25–40 guests), kitchen staff (1 per 50 guests), and optional coat check (1 per 80–120 guests) and valet (1 per 30–50 guests). Captains coordinate service flow and are essential for events over 75 guests.

  • Captain/maître d': 1 per 75–100 guests, coordinates timing and flow
  • Bussers: 1 per 25–40 guests, clear plates and reset tables
  • Kitchen staff: 1 per 50 guests, prep and plate food on-site
  • Coat check: 1 per 80–120 guests (winter/formal events)
  • Valet: 2+ drivers per 30–50 guests (if parking is limited)
Q

What guest-to-staff ratio should I aim for?

An overall guest-to-staff ratio of 8:1 to 12:1 is standard for well-run events. High-end galas aim for 6:1. Budget events can manage with 15:1. The ratio depends on service style — plated dinners require the most staff, while buffets need the least.

  • Luxury gala: 6:1 guest-to-staff (premium experience)
  • Plated wedding: 8:1 to 10:1 (standard quality service)
  • Buffet reception: 12:1 to 15:1 (less labor required)
  • Cocktail party: 10:1 to 12:1 (bartender-heavy, fewer waiters)
