What to bring
Scaling a picnic spread to your guest list
Planning food for a group is really two decisions: how much per person, and how many people. This tool handles both by applying a common entertaining guideline — a food weight per adult that scales up with how substantial the meal is, and a half-portion adjustment for children — so you get one total instead of guessing dish by dish.
Duration matters too. A quick hour-long get-together needs less food and fewer drinks than an all-afternoon gathering where people graze on and off, and outdoor settings mean more hydration the longer the event runs, especially in the sun. This is a total-spread planner; if you want quantities broken down by individual dish, use a dedicated portion planner instead.
Frequently Asked Questions
How does this calculator estimate how much food I need?
It uses a common entertaining guideline that assigns a food weight per adult depending on how substantial the meal is — about half a pound for a light snack spread, three-quarters of a pound for a standard meal, and a full pound for a hearty, meal-replacing spread — then adds it up across your whole guest list.
Why do children only count as half a guest?
Kids typically eat noticeably less than adults at a shared spread, so counting each child as half an adult portion keeps the total closer to what actually gets eaten instead of over-buying. If you know your group of kids eats more like adults, just add them as extra adults instead.
Why does a longer event need more drinks per person?
The calculator assumes 2 servings (roughly 12 oz each) per guest for the first two hours, then adds one more serving per guest for every additional hour. Outdoor events add heat, sun, and activity on top of normal thirst, so longer gatherings need steadily more hydration, not just a flat amount per head.
How do I avoid running short or buying way too much?
Use the total as your starting shopping list, then adjust for your specific guests: a group of big eaters or teenagers will run over the estimate, while a lighter crowd or a spread with lots of competing dishes may run under it. It's easier to trim a slightly-too-big shopping list than to make an emergency store run mid-picnic.
A planning starting point only. Appetites vary a lot by group, weather, and how many other dishes are on the table — adjust up or down based on who’s actually coming.
