Everything you need to know about calculating food for your next event

The Golden Rule of Party Food

The most common mistake hosts make is underestimating how much food they need. The golden rule: it's always better to have leftovers than hungry guests. Plan for 10-15% more food than your calculations suggest.

How Much Food Per Person?

Here are the standard serving sizes for popular party foods:

  • Pizza: 3 slices per adult (about 1/3 of a large pizza)
  • Wings: 6-8 wings per person as an appetizer
  • Burgers/Hot Dogs: 1.5-2 per person
  • Tacos: 3 tacos per person
  • Nachos: 15 chips with toppings per serving
  • Salad: 1.5 cups per person as a side
  • Drinks: 2 per person for a 2-3 hour event
  • Cake: 1 slice per person

Adjusting for Your Crowd

Not all parties are created equal. Adjust your calculations based on:

Increase quantities by 25% when:

  • Guests are mostly adults with big appetites
  • The event is during a mealtime
  • There's alcohol being served (people eat more)
  • It's a long event (4+ hours)
  • The food is the main attraction (like a BBQ)

Decrease quantities by 25% when:

  • Serving multiple types of food
  • Many children attending
  • It's a cocktail party with apps only
  • Guests just ate or will eat elsewhere

Timing Matters

When you serve food affects how much people eat:

  • Lunch parties (11am-2pm): Plan for full meal portions
  • Afternoon parties (2-5pm): Reduce by 20%, people snack less
  • Dinner parties (6-9pm): Full portions, people are hungry
  • Late night (9pm+): Increase by 15%, late night munchies are real

The Multi-Food Strategy

Serving multiple foods? Reduce each item by 30-40%. If you're serving pizza AND wings, you don't need full portions of each. Use our calculators and toggle "Serving other food" for adjusted quantities.

Common Mistakes to Avoid

  1. Not accounting for no-shows: Typically 10-20% of invited guests don't attend
  2. Forgetting vegetarians: Always have at least one veggie option
  3. Ignoring dietary restrictions: Ask guests in advance
  4. Running out of drinks: People drink more than you think
  5. Not enough ice: Plan for 1 lb of ice per person for drinks, more for coolers

Real Planning Scenario and Tradeoff Signals

Scenario baseline: 30-person mixed crowd baseline. Start from a mixed menu with one anchor entree and two shared sides, then trim or expand by appetite profile.

Failure Cases Seen in This Scenario

  • โ€ขOrdering exact headcount quantities with no late-arrival buffer.
  • โ€ขServing all hot food at once, causing quality drop in hour two.
  • โ€ขSkipping a vegetarian fallback and forcing last-minute substitutions.

Budget Tradeoffs for Better Coverage

  • โ€ขPrioritize one premium anchor dish and keep sides cost-efficient.
  • โ€ขReplace half of premium drinks with self-serve options to hold budget.
  • โ€ขUse appetizer density to reduce expensive main-protein overages.

Baseline menu: $240. A +10 guest plan usually lands near $310 (+$70 delta).

Execution Timing Plan

  1. T-48hLock menu, confirm guest count band, and pre-buy shelf-stable items.
  2. T-24hPrep cold sides and split staging between hot and cold zones.
  3. T-90mStart anchor dish and set first-wave service tray.
  4. T+60mRefresh with second-wave food instead of topping up old trays.

What Changes at +10 Guests

  • โ€ขIncrease anchor dish by roughly one-third before adding extra side variety.
  • โ€ขMove from single drink station to two points to avoid service bottlenecks.
  • โ€ขAdd one simple backup tray to protect against unexpected appetite spikes.
