**Quick answer:** For a graduation party buffet, standard catering rules of thumb are: plan roughly 1 to 1.5 pounds of food total per adult, with about 5 to 6 ounces of protein and two to three sides of about 4 ounces each per person; count children as roughly half an adult portion; and add about 10 percent as a buffer. Appetite runs higher when the party spans a mealtime and lower for a mid-afternoon drop-in. These are estimates for planning — confirm exact quantities with your caterer based on your real headcount, timing, and menu. You invited fifty people. Ninety said maybe. Your kid invited the whole team. And now you are standing in a kitchen trying to answer the one question nobody ever teaches you: *how much food is enough?* Running out in front of a hundred guests is a specific kind of nightmare. Here are the numbers people in catering actually plan with. ## The core rules of thumb (per adult, buffet-style) - **Total food:** about 1 to 1.5 pounds per adult across everything on the table. - **Protein / main:** about 5 to 6 ounces cooked per person — more if it is the centerpiece, like smoked brisket. - **Sides:** plan two to three, at roughly 4 ounces each per person. - **Bread or rolls:** about 1 to 1.5 per person. - **Dessert:** about 1 to 2 pieces per person. - **Drinks:** about 2 to 3 servings per person for a party spanning a couple of hours. Say it plainly: these are planning estimates, not exact science. Menus, crowds, and timing move the numbers. Confirm with your caterer before you commit. ## Adjust for your actual party - **Timing.** A party that covers lunch or dinner needs full portions. A mid-afternoon drop-in between two and four needs noticeably less — people are grazing, not eating a meal. - **Crowd.** Teenagers and athletes eat more than the chart says. An older crowd eats less. A graduation party usually has both, which tends to average out — unless the guest list is mostly the team. - **Kids.** Count children as roughly half an adult portion. - **Buffer.** Add about 10 percent so you are not cutting it close. Leftovers at a grad party are a feature, not a bug. ## Do not forget the guest who eats gluten-free With celiac disease and gluten sensitivity as common as they are, a guest list of a hundred almost certainly includes someone who cannot safely eat a standard spread. The awkward version of this is a separate plate in the corner of the table, which singles someone out and still carries cross-contact risk from a shared kitchen. The simple fix is a menu that is gluten-free across the board, so nobody gets singled out and nobody gets sick on the big day. A dedicated gluten-free caterer removes the whole problem — there is no second menu to manage, because everything is safe. > "Running out of food at your kid''s graduation is a specific kind of panic. Plan for a pound to a pound and a half a person, add a little cushion, and make sure the celiac cousin can eat too. Then relax." > — Lew Kizer ## Or skip the math entirely A caterer does this arithmetic for a living.
