Party planning calculator questions
How do I estimate food for a party?
Start with the number of adults and children, choose the party type, then estimate mains, sides, drinks, desserts and supplies together. PartyPrepList turns that food estimate into package counts so the list is easier to shop.
How much food do I need per person for a party?
For a full meal, plan one main serving per person plus sides, drinks and dessert. Children usually need smaller food portions, while cups, napkins and plates often stay close to one per guest or more.
What is the easiest way to make a party shopping list?
Use a calculator that converts servings into grocery units such as pizzas, bags, cans, bottles, trays, plates and ice. That avoids strange decimals and gives you a shopping list you can print or copy.
Where do the quantities come from?
We use standard catering formulas based on guest count, event duration, and meal style. Quantities are estimates because appetite, weather and event flow can change what people actually eat.
Can I adjust the numbers?
Yes. You can switch between Conservative, Standard, and Generous serving levels. You can also adjust package size or price for local stores.
