How Much Catering Food Per Person: A Lansing Portion-Planning Guide

Published July 9, 2026 by Lansing Catering Co

How much food to order is the question that keeps hosts up the night before an event. Order too little and the last table through the buffet gets picked-over trays. Order way too much and you have paid for food that goes home in foil. The good news is that catering quantities follow reliable rules, and once you know the per-person amounts, planning a party for 30 or 300 becomes simple arithmetic. Here is how we size an order for weddings, corporate lunches, and celebrations around Lansing, East Lansing, Okemos, Holt, Haslett, and Mason.

Two decisions shape everything else: whether the meal is plated or a buffet, and whether appetizers come before dinner or stand in for it. Settle those first, then the numbers below fall into place.

The Main Dish: Start With the Protein

The main protein anchors the order, so size it first. For a dinner, plan roughly 6 ounces of cooked, boneless protein per person. For a lunch, when appetites run lighter, 4 to 5 ounces is plenty. If you offer two proteins on a buffet, say chicken and a beef or salmon option, plan about 4 ounces of each per person, because most guests take a little of both rather than a full portion of one.

One detail trips people up: cooked weight versus raw weight. Meat loses weight as it cooks, and bone-in cuts carry weight you do not eat. A caterer orders raw to hit a cooked target, so when you are estimating, think in finished portions and let the kitchen handle the conversion. That is also why a "6 ounce portion" on the plate might start as 8 or 9 ounces of raw chicken.

Sides, Salad, and Bread

Around the protein, the supporting dishes follow their own per-person amounts. Most dinners run two sides, and that pairing is the sweet spot for variety without waste.

Starches like potatoes, rice, or pasta sit at the higher end of the side range because they are filling and popular. Vegetable sides can run a touch lighter. When in doubt, a little extra on the sides is cheaper insurance than running short on the protein.

Appetizers: The Piece Count That Changes Everything

Appetizers are where hosts most often miscalculate, because the right number depends entirely on their job. There are two very different scenarios.

Appetizers before a meal. When a full dinner follows, appetizers are a light welcome. Plan 3 to 5 pieces per person for the first hour, across a few options. You are taking the edge off, not feeding the room.

Appetizers as the meal. At a cocktail-style reception with no seated dinner, the appetizers are dinner, and the count jumps. Plan 10 to 14 pieces per person for a two-hour event, and 12 to 16 for something longer. Spread them across at least four to six options, mix hot and cold, and include a substantial item or two, sliders, a carving or pasta station, so guests leave satisfied rather than hunting for real food on the way home.

A cheese and charcuterie spread makes a lovely grazing station at either kind of event; plan about 2 ounces of cheese per person when it is one of several appetizers. For how these formats compare on service and cost, our buffet vs plated vs family-style guide is the companion to this one.

The Buffet Buffer

Here is the single most useful adjustment in catering math. A buffet needs more food than a plated meal for the same headcount, because self-serve portions are larger and less consistent than a plate built in the kitchen. Plan roughly 10 to 20 percent more across the board for a buffet. That buffer is what stands between a smooth line and the awkward moment when the last guests find empty chafing dishes. Plated events, by contrast, let you order tight, since every portion is controlled.

Guest mix matters too. A crowd of teenagers or a hungry post-game group eats more than a light-lunch office group. Tell your caterer who is in the room, and the estimate gets sharper.

Drinks and the Beverage Count

Beverages follow the clock. Plan about one drink per person per hour, with a little extra in the first hour when everyone arrives at once and reaches for something. For a three-hour reception, that is roughly three to four drinks per guest. Always over-provide water and non-alcoholic options, and for a summer event, budget extra cold drinks, because a July afternoon in Lansing moves a lot more lemonade and iced tea than a climate-controlled ballroom. Our summer outdoor catering guide covers hot-weather planning in more detail.

Timing and the Food-Safety Window

Quantity is not the only number that matters; time on the table matters too. Perishable food should not sit out more than two hours, or one hour when it is above 90 degrees, according to federal food-safety guidance. That is why a good caterer replenishes in smaller batches and keeps back-of-house reserves hot or cold rather than laying everything out at once. It also means ordering enough is only half the job; serving it safely across the event is the other half, especially outdoors under a tent.

Putting It Together: A Worked Example

Say you are hosting a 100-guest wedding dinner in Okemos, served buffet style. Start with the base per-person amounts, then apply the buffet buffer:

• Protein: 6 oz x 100 = about 38 pounds cooked, then add 15 percent for the buffet. Split across two proteins, that is roughly 3 ounces of each per guest.
• Sides: two sides at 5 oz each, plus the buffet buffer.
• Salad: 100 cups, dressing on the side.
• Rolls: 150 to 200, allowing for seconds.
• Dessert: 100 to 150 servings if you offer a small variety beside the cake.
• Drinks: for a four-hour reception, plan 4 to 5 beverages per guest, weighted toward the first hour and the toast.

The same framework scales down to a 25-person office lunch or up to a 300-guest gala. For how these portions translate into a per-plate price, see our wedding cost per person guide and corporate lunch catering guide, and browse dishes that portion cleanly on our menu page.

Frequently Asked Questions

How much main dish per person for catering?

For a dinner, plan about 6 ounces of cooked, boneless main protein per person, or 4 to 5 ounces for a lunch. If you serve two proteins on a buffet, plan roughly 4 ounces each, since guests take some of both. Bone-in cuts weigh more before cooking, so ask your caterer for the raw weight to order for the cut you choose.

How many appetizers per person should I order?

When appetizers come before a meal, plan 3 to 5 pieces per person for the first hour. When passed or stationed appetizers are the meal, as at a cocktail reception, plan 10 to 14 pieces per person for a two-hour event across a variety of options. Offer at least four to six different items so the selection feels generous.

How much more food do you need for a buffet?

Plan roughly 10 to 20 percent more food for a buffet than for a plated meal. When guests serve themselves, portions run larger and less predictable than a plated portion built in the kitchen. Ordering that buffer keeps the last guests through the line from finding empty trays, which is the most common catering complaint at self-serve events.

How many drinks per person for an event?

A good rule is about one drink per person per hour, with a little extra in the first hour when guests arrive thirsty. For a three-hour event, plan roughly three to four drinks per guest. Always provide plenty of water and non-alcoholic options, and count on more cold drinks for a summer outdoor event in the Lansing heat.

How much food per person for a cocktail reception?

If appetizers replace dinner, plan 10 to 14 pieces per person for a two-hour reception and 12 to 16 for longer, spread across passed and stationed items. Include a mix of hot and cold, a substantial option or two like sliders or a carving station, and a couple of vegetarian choices so the reception eats like a full meal, not a snack.

How do you plan catering quantities for a Lansing event?

Start with a firm headcount, decide whether appetizers precede or replace the meal, then apply per-person amounts for protein, two sides, salad, and dessert. Add a 10 to 20 percent buffet buffer, plan one drink per person per hour, and account for dietary needs. Share the final numbers with your caterer once RSVPs close so the order matches the room.
