Catering Portion Calculator
For catered dinner service, plan 6 to 8 ounces of cooked protein, 4 to 6 ounces of each major side, and one dessert serving per adult.
Estimate quantities for plated meals, buffets, and receptions, then translate servings into purchasing units using your recipes' actual yields.
Kids are counted as about 60% of an adult portion. Appetite and leftover adjustments are shown in the result.

Catering quantities by service type
Plated service controls portions closely, so one contracted meal per attendee plus approved extras is usually sufficient. Buffets need roughly 10 to 15 percent more because serving sizes vary and guests sample several items. Stations and family-style meals fall between those models. For appetizers, allow 4 to 6 pieces before dinner or 12 to 15 pieces when they replace the main meal.
A standard dinner baseline is 6 to 8 ounces cooked protein, 4 to 6 ounces of each principal side, 1 to 2 ounces bread, and one dessert. With several sides, reduce the amount of each. For two proteins, forecast the preferred-choice split rather than ordering a full portion of both for every person. Record whether every figure refers to purchased, cooked, or plated weight.
From headcount to production sheet
Start with guaranteed guests, then add vendors, staff meals, dietary meals, and any contractual overage. Convert child counts using the agreed menu portion. Multiply by serving size, divide by recipe yield, and round to practical batch and case sizes. Apply one explicit buffer at the end so repeated rounding does not create excessive waste.
The production plan should identify batch count, pan size, holding equipment, refill timing, and safe temperature. Keep part of each item off the first buffet and replenish smaller pans. Log actual use after service; leftovers and shortages improve future estimates far more than generic rules. The calculator provides a fast check, while tested recipes and venue procedures remain the final authority.
