How to Use This Calculator
Enter guests and appetite

Different slice counts per pizza change how many pies you’ll need to order or bake.
Make topping & side decisions
Follow the variety suggestion and side portions to keep everyone satisfied.
Formula
Total slices = (Adults × slicesadult) + (Kids × sliceskid)
Pizzas needed = ceiling(Total slices ÷ slices per pizza)
Example: 10 adults, 4 kids, normal appetite → slices = 10×3 + 4×1.8 = 40.2 → large pizzas (10 slices) = 5 pies.
Tip: Add one extra pizza for late-night leftovers or unexpected guests.
Full Description
Hosting a pizza night? This calculator removes the guesswork from ordering or baking the right amount. Enter your guest count, appetite level, and pizza size to automatically determine how many pies to plan for. The tool also estimates beverage and side quantities so you can balance your menu without overbuying.
Adjust appetite levels to account for mixed events (kids’ parties versus sports watch parties) and toggle dessert planning if you’re serving sweets. Use the topping variety suggestion to ensure there’s something for everyone without overwhelming the table.
Perfect for
- Ordering delivery or planning a make-your-own pizza bar.
- Office lunches, kids’ birthdays, and game-day gatherings.
- Pop-up events where dough and toppings must be portioned precisely.
- Meal prep for freezer pizzas or par-baked crusts.
Keep allergen needs in mind and provide a vegetarian or gluten-free option if necessary. Track feedback from guests to fine-tune slice assumptions for future parties.
Frequently Asked Questions
How many pizzas should I order for leftovers?
Add one or two extra pizzas if you want guaranteed leftovers or anticipate late arrivals.
Do kids always eat fewer slices?
Not always. For teen parties, treat them as adults or bump appetite to hearty.
What if pizzas come uncut?
Use slice counts as a guide—communicate with the restaurant to pre-cut into equal slices.
Can I convert to metric?
Yes. Convert slice counts to total pizza area and order by diameter or square centimeters from your bakery.
