Pizza serving rule
3 slices per adult and 2 slices per child
Use the higher end when pizza is the clear main meal. Pull the count down when wings, dessert, salads, or open-house grazing share the table.
Best for: Pizza pickup, school parties, casual birthdays, and game-day pizza spreads.
Open Pizza & Cake CalculatorChicken wing rule
4-6 party-wing pieces when wings are one appetizer in a spread, or 10-12 when they are the main food
A raw pound usually yields 8-10 split pieces or 4-5 whole wings, which helps translate guest count into pounds before ordering.
Best for: Watch parties, casual buffets, sports nights, and wing tray orders.
Open Chicken Wing CalculatorTaco bar rule
1/3 lb taco meat, 2.5 shells, 2 oz cheese, and 1/2 cup beans-and-rice total per person
This is the default mixed-crowd baseline for buffet-style taco bars. Heavier appetites and lighter side support push the meat line higher.
Best for: Taco bars, graduation food lines, backyard parties, and self-serve buffet tables.
Open Taco Bar CalculatorParty ice rule
1.5 pounds of ice per guest
That translates to about 45 pounds for 30 guests, 75 pounds for 50 guests, and 150 pounds for 100 guests before outdoor-heat buffer.
Best for: Cooler parties, drink tubs, outdoor parties, and longer self-serve drink stations.
Open Ice CalculatorDrink pacing rule
2 drinks in the first hour and 1 drink for each additional hour
This is the starting point for mixed drink menus before you split the count into beer, wine, soda, water, or zero-proof lanes.
Best for: General drink planning, birthdays, showers, game-day gatherings, and backyard events.
Open Party Drink CalculatorCharcuterie board rule
4 total ounces per person for appetizer service or 8 ounces per person for meal service
The standard mixed board splits that total into about 40% cheese, 30% meat, 20% fruit or vegetables, plus 2 crackers per guest.
Best for: Wine nights, showers, grazing tables, and snack-forward hosting.
