🍽️ Party Food Quantity Calculator
Enter your guest count, pick how hungry the crowd is, and add your dishes to see exactly how much to buy — per-item and grand totals in grams and kilograms, so you cater confidently without waste.
🎉 Plan the Spread
What is a Party Food Quantity Calculator?
It scales per-person catering amounts up to a whole party. Tell it how many guests are coming and how hungry they'll be, list your dishes with a per-person gram figure (handy presets are built in), and it returns the total quantity for each item plus a grand total in grams and kilograms.
Use it to write a precise shopping list, split cooking across a group, or sanity-check a caterer's quote. The appetite factor lets you dial the whole spread up for a big-appetite crowd or down for a lighter reception, so you buy enough without drowning in leftovers.
❓ Frequently Asked Questions
How does the party food quantity calculator work?
Enter your number of guests, choose an appetite level (light, moderate, or hearty), and add the items you're serving with a per-person amount in grams. It multiplies each item by your guest count and the appetite factor, then shows the total for every item plus a grand total in both grams and kilograms.
How much food should I plan per person?
Common catering rules of thumb are about 200 g of main protein, 150 g of sides, 80 g of salad, 100 g of dessert, and 60 g of bread per person — presets this calculator provides. Scale up for a hungry crowd or a long event, and down for an afternoon do or when there are many dishes competing for the same appetite.
What do the appetite levels do?
They apply a multiplier to every quantity: light is 0.8, moderate is 1.0, and hearty is 1.3. Pick light for a canapé-style reception or a hot day, moderate for a standard sit-down meal, and hearty for a big-appetite crowd, an all-day event, or when the food is the main attraction.
How do I avoid running out or over-catering?
Count adults and hungry teens at full appetite and children at a reduced amount, add a small buffer for seconds on popular dishes, and remember that more dish choices means people take a little of each. When in doubt, slightly over-cater on crowd-pleasers and shareable items — leftovers are easier to manage than an empty platter.
