Methodology
How we calculate this
Children are converted to adult-equivalent portions, then meal style and event duration adjust each food category.
The math
- Adult equivalents = adults + (children × 0.6)
- Category quantity = adult equivalents × portion allowance × meal and duration factors
Worked example
Twenty adults and five children equal 23 adult portions before meal-style and duration adjustments.
Frequently asked questions
Helpful answers
How much food should I plan per party guest?
For a full meal, plan roughly 6 to 8 ounces of main dish or protein plus sides, appetizers, and dessert per adult-sized portion.
How should children count in a party food estimate?
A practical starting point is about 50% to 65% of an adult portion, depending on age and appetite.
Should I make extra food for a buffet?
A modest buffer helps because guests choose different foods and serving spoons create uneven portions. Ten percent extra is often enough when several dishes are available.
