You might be wondering how much catering to order for 20 people. Whether it is a birthday party or a corporate lunch, figuring out the right quantities can feel intimidating. Good news, this process can be simpler than it looks. By planning around event type, dietary needs, and realistic portion sizes, you ensure your guests are satisfied without overspending.
Plan for event type and dietary needs
When you are hosting a casual birthday gathering or an elegant wedding reception, plan your menu first. Casual events with finger foods can work well with smaller servings, while formal dinners often call for more substantial portions. Catering services commonly tailor their offerings for social events (Candlelight Inn Restaurant), so do not hesitate to ask for practical suggestions.
It also helps to ask guests about dietary restrictions in advance (Tripleseat). Some may be lactose intolerant (Healthline), others might prefer dairy-free choices, and a few could be watching carb intake for health reasons. By communicating these needs to your caterer, you can easily arrange a balanced selection that covers everything from keto-friendly to diabetic-safe options.
Calculate portions carefully
Portion sizes matter more than you might think. Researchers have found that people tend to eat more when offered larger servings, known as the “portion size effect” (NCBI). Over-ordering can lead to waste and bigger bills. On the flip side, if you order too little, guests might feel they did not get enough.
Below is a quick-look table to guide your estimates for parties of about 20 guests. These figures assume a sit-down or buffet meal with moderate appetites:
| Item | Per Person Estimate | Total for 20 Guests |
|---|---|---|
| Protein (chicken, fish, or similar) | 6–8 oz (about 1 serving) | 8–10 lb total |
| Side dish(es) | 4–6 oz (1–2 small scoops) | 5–7 lb total |
| Salad or vegetables | 3–4 oz (a handful) | 4–5 lb total |
| Dessert | 1 slice or 1 small portion | 20 portions, plus a few extra |
You can adjust to match your menu and event style. If you are serving multiple proteins, you might reduce each type slightly, since people often sample more than one. If you want budget-friendly options, you can explore what is the cheapest food to cater? for creative alternatives.
Include variety for different diets
Offering multiple menu options keeps everyone happy. You might include a vegetarian pasta, a dairy-free salad, and a lean protein for the main dish. According to Tripleseat, labeling each dish with ingredients or dietary notes helps guests pick confidently. That way, those who need low-glycemic or low-carb foods can easily spot which choices are safest for them (Healthline).
Good news, many caterers in Baltimore are used to adapting meals for special requests. A few thoughtful swaps (like grilled veggies instead of cheese-filled sides) can help you accommodate most needs without increasing costs.
Check your cost and finalize
Before confirming your final order, take a moment to look at your event budget.

If you already have a budget in mind, see if it lines up with what you are ordering.
You could also compare whether catering is a better deal than booking a restaurant if you are hosting a large group.

Plus, for business functions, you may want to consider the current IRS deductions for business-related food and beverages, which sometimes allow a 100% write-off from certain restaurants (IRS.gov).
Summarize your catering plan
In a nutshell, focus on three key areas. First, plan around the type of event you are hosting, factoring in any dietary needs. Second, be mindful of portion sizes to avoid over- or under-ordering. Third, confirm the budget and check possible deductions for business events if that applies. By balancing these elements, you can feel confident about how much catering to order for 20 people.
