About PartyPrepList

PartyPrepList is an independent collection of free calculators for people planning parties, weddings, cookouts, classroom events, office lunches, and other group meals. We built it to turn vague serving advice into a practical shopping list.

What the calculators do

Each calculator starts with common serving-size rules, then adjusts the estimate using the information you enter. Depending on the tool, that can include the number of adults and children, event duration, meal style, number of side dishes, appetite level, package size, and a small buffer for seconds.

Results are converted into shopping units such as pizzas, pounds, bottles, cases, cans, bags, trays, cups, and plates. Calculations run in your browser and update as you change the inputs.

Our calculation method

Use a transparent per-person or per-hour starting quantity.
Apply adjustments for children, serving style, sides, event duration, and expected appetite.
Round up to whole packages so the result can be used while shopping.
Show the assumptions on each calculator page so users can check and change them.

Important: These results are planning estimates, not professional catering advice. Appetite, weather, local package sizes, dietary needs, and the rest of the menu can change the final quantity. For a large or high-stakes event, confirm the numbers with a caterer or venue.

How we improve the site

We review calculations when users report a problem, test tools on mobile and desktop, and update explanations when an assumption is unclear. We do not publish a calculator just to target a search phrase; every calculator is intended to produce a useful, adjustable result.

Feedback and corrections
