A hungry crowd can turn a perfectly planned party into a picked-over tray in a hurry. This catering portion guide helps you order enough of the good stuff – stacked sandwiches, tender corned beef, crisp salads, hearty sides, and dessert – without paying for a mountain of leftovers.
The first question is not just, “How many people are coming?” It is, “How are they coming?” An office lunch at noon, a graduation party that runs all afternoon, and a game-day gathering with a refrigerator full of drinks call for different portions. Plan for the people, the timing, and the appetite. Around here, nobody is impressed by a skimpy sandwich tray.
Start With the Type of Event
A catered meal should fit the occasion. If food is the main event, your quantities need to carry the whole room. If guests are grazing between speeches, games, or cocktails, you can scale back a little while offering more variety.
For a straightforward office lunch, plan on one full sandwich per guest when sandwiches are the centerpiece, plus sides and dessert. If the group includes big eaters, active crews, or people skipping breakfast, add 10 to 20 percent. It is better to have a few sandwiches left in the break room than a team staring at an empty tray at 12:20.
For family parties, showers, and open-house celebrations, food often stays out longer and guests arrive in waves. Plan a little more generously. Early arrivals may eat lunch, late arrivals may make it dinner, and somebody always brings a teenager who can put away two sandwiches without blinking.
A dinner event calls for the biggest portions. When deli meats, hot entrées, or sandwich platters are the meal, build in a full serving for every adult plus a cushion. If you are serving several substantial dishes, guests may take smaller portions of each, but they still expect a satisfying plate.
Catering Portion Guide by Guest Count
These ranges are a practical starting point for a full deli-style meal. They assume adults are eating sandwiches or a protein-based main course along with sides. Kids, light eaters, and dessert-only guests can bring the average down, while hungry work crews and sports crowds can send it up fast.
| Guest count | Sandwiches or main servings | Deli meat for build-your-own service | Sides | Dessert servings | |—|—:|—:|—:|—:| | 10 guests | 11-12 | 4-5 pounds | 10-12 | 10-12 | | 20 guests | 22-24 | 8-10 pounds | 20-24 | 20-24 | | 30 guests | 33-36 | 12-15 pounds | 30-36 | 30-36 | | 50 guests | 55-60 | 20-25 pounds | 50-60 | 50-60 |
For build-your-own sandwich spreads, about 6 to 8 ounces of deli meat per adult is a dependable range. Choose the higher end when corned beef, pastrami, or another crowd favorite is on the table. Those are not the trays people politely pass by. Add enough bread or rolls for at least one and a quarter sandwiches per guest, along with cheese, condiments, and toppings.
If you are serving pre-made sandwich trays, one sandwich per person works for most lunch meetings when there are filling sides. Order extra when the sandwiches are smaller, the event stretches past an hour, or your guests are known for big appetites. A room full of hungry people does not need a lecture on portion control. It needs another tray.
Get the Sides Right
Sides make a catered meal feel complete, but they are also where hosts either overbuy or come up short. For potato salad, coleslaw, pasta salad, macaroni and cheese, or similar hearty dishes, plan on 4 to 6 ounces per person when serving two sides. If one side is doing most of the work, increase that to 6 to 8 ounces per guest.
A simple way to think about it: two sides give guests choices; three sides give the table abundance. For a 20-person office lunch, two large side options are usually enough. For a graduation party or family gathering where guests linger, three options work better – for example, a creamy salad, a vegetable-forward choice, and something warm or extra hearty.
Do not forget the supporting players. Pickles, chips, rolls, and condiments may not be the headline, but they make the meal feel like a real deli spread. Plan roughly 1 to 2 pickle spears per guest, a small handful of chips per person if they are included, and extra mustard, mayo, and dressing. Nobody should have to scrape the last bit of mustard from a nearly empty packet.
Dessert Depends on the Rest of the Menu
When dessert is the only sweet offering, order one serving per guest and a few extras. Cookies and brownies are easy crowd-pleasers because they can be served individually and do not require plates, forks, or a lot of setup.
If there is a birthday cake, a candy table, or guests are bringing desserts, you can reduce your order. In that case, plan for about two-thirds of the guest count. At an afternoon party with coffee, though, dessert tends to disappear faster than expected. People who passed on a second sandwich rarely pass on a cookie.
Adjust for Kids, Timing, and Guest Habits
Guest count is only the beginning. A group of 25 adults does not eat like 25 elementary-school kids, and a 6 p.m. dinner crowd does not eat like a 2 p.m. open house crowd.
For young children, estimate about half an adult portion. For older kids and teens, count them as adults, especially when sandwiches and fries are involved. Teen athletes, construction crews, movers, and all-day event staff may need one and a half servings each. That is not excess. That is knowing your audience.
Timing matters, too. A meal served between noon and 1 p.m. has a clear lunch expectation. Food set out at 3 p.m. may be treated as a snack, unless the invitation says dinner follows. Evening events require more food, particularly if alcohol is available or guests are arriving directly from work.
If your event runs longer than three hours, do not simply put all the food out at once. Hold back part of the order and refresh the spread later. It keeps the food looking better, helps manage temperature, and gives late arrivals the same welcome as the first people through the door.
Variety Is Better Than Guesswork
You do not need six sandwich varieties for a group of 12, but one choice rarely serves everyone. A smart catering order gives people a few familiar options: a signature meat sandwich, turkey or ham, a vegetarian selection, and a mix of breads or wraps when appropriate.
For larger groups, variety becomes more useful. Guests have preferences, dietary restrictions, and strong opinions about onions. Ask for headcount details before ordering: vegetarians, guests avoiding pork, gluten-sensitive attendees, and anyone with food allergies. Separate labeled options are far easier than trying to identify sandwiches after the trays have been opened.
The same goes for the main attraction. If you know your crowd loves corned beef, make it the hero and plan toward the generous end of the range. Bronx Deli has built its name on award-winning corned beef for a reason: when the food is that good, people come back for another bite.
Avoid the Two Most Common Catering Mistakes
The first mistake is ordering exactly to the headcount. Headcount is a baseline, not a finish line. Add a small buffer for most events, especially when food is replacing a meal. Ten percent extra is usually enough for a typical gathering; go closer to 20 percent for big eaters or all-day events.
The second mistake is ordering too many different things in tiny amounts. A table with five nearly empty trays feels less generous than a table with a few full, well-chosen favorites. Start with enough of the main course, add two satisfying sides, then bring in dessert and extras. Your guests will remember that the food was plentiful, not that there were twelve labels.
Place Your Order With a Real Plan
Before calling in your catering order, have four details ready: your guest count, serving time, whether food is lunch or dinner, and any dietary needs. Tell the catering team whether people will sit down together or come and go. That one detail can change the right amount of food.
Give yourself time, especially for larger events or busy weekends. A good caterer can help you shape the order, but they cannot read the room the way you can. Be honest about your crowd. If your family has a reputation for building towering sandwiches and circling back for seconds, say so proudly.
A generous table does more than feed people. It gives guests a reason to settle in, swap stories, and ask, “Who brought this?” Order for the moment you want to create – then make sure there is enough left for the person who arrives fashionably late.
