Question 1

How many slices are in a large pizza?

Accepted Answer

Most large pizzas come with 10 slices, though this can vary by pizzeria. Small pizzas typically have 6 slices, medium has 8, and extra-large has 12. The calculator uses industry standard slice counts for accurate estimates.

Question 2

Should I order extra pizza if I have teenagers?

Accepted Answer

Absolutely! Teenagers often eat 4-5 slices each (compared to 2-3 for adults). The calculator has a special 'Teenagers' mode that accounts for this increased appetite. It's always better to have leftovers than hungry teens!

Question 3

How do I handle dietary restrictions when ordering?

Accepted Answer

Use the dietary sliders to indicate what percentage of your guests need vegetarian, vegan, or gluten-free options. The calculator will show you how many of each type to order. Pro tip: Many meat-eaters enjoy veggie pizzas too, so having extra vegetarian options rarely goes to waste.

Question 4

Is it cheaper to order multiple mediums or fewer larges?

Accepted Answer

Generally, large pizzas offer the best value per slice. The calculator includes a cost optimizer that compares prices and recommends the most economical size combination. Large pizzas are typically 20-30% cheaper per slice than mediums.

Question 5

Should I order extra for leftovers?

Accepted Answer

Cold pizza for breakfast is a universal joy! The calculator has a 'Leftovers' setting - select 'some' for 1-2 leftover slices per person, or 'lots' if you want substantial leftovers. Pizza stays good refrigerated for 3-4 days.

Question 6

How much pizza do kids actually eat?

Accepted Answer

Kids typically eat about half what an adult eats (1.5-2 slices vs 3). Enable the 'Has Kids' toggle and set the percentage, and the calculator automatically adjusts the total. If kids are under 10, they may eat even less.
