How many supplies per guest?

People use more disposables than you'd think. They set a cup down, forget it and grab a new one, or take a fresh plate when they go back for dessert. Party supply makers plan on these amounts per guest:

ItemPer guest
Small appetizer plates2
Dinner plates1
Dessert plates1
Cups3
Napkins3
Cutlery sets1 for a meal

Example: 25 guests, appetizers and a meal, 10% extra

  • Appetizer plates: 25 × 2 × 1.1 = 55
  • Dinner plates and cutlery sets: 28 each
  • Cups and napkins: 83 each

Small things that help

  • Put out cup markers or a marker pen so guests can write their names on cups.
  • Choose sturdy plates for heavy foods like barbecue. Flimsy ones buckle.
  • Set out trash and recycling bins where people will see them.
  • Packs usually come in round numbers, so round up to the next pack.

Work out the food with the party food calculator and the tables with the table and seating calculator.

Frequently asked questions

How many cups per person for a party?

About three per guest. People lose track of their cup and grab a new one, especially at longer parties.

How many napkins do I need?

About three per guest, more if you're serving messy foods like wings or ribs.

Do I need dessert plates?

They're handy if dessert is served after the meal, since most guests won't reuse a dinner plate for cake.

How many trash bags for a party?

Plan on at least two, and about one for every 15 guests.
