Slices per person — a working baseline
These are starting points, not laws. Adjust for known big eaters or light eaters in your group:
- Adults: 3 slices average. Heavier eaters trend to 4; lighter to 2.
- Kids 5–12: 2 slices.
- Kids under 5: 1 slice (often less, but order the whole slice anyway).
- Teens: count them as adults +1 slice — they often outpace the grown-ups.
Slices per pizza
Chain pizzas usually cut into:
- Small / medium: 6–8 slices.
- Large: 8 slices (sometimes 10).
- X-large / specialty: 10–12 slices.
Slice count varies by brand and franchise — call ahead if the cut shape matters.
Size mix for common group sizes
- 5–10 people: 3 large pizzas is a common safe target. Mix one cheese, one popular topping, one specialty.
- 10–20 people: 6–8 large pizzas. Add one veggie/vegan option if anyone in the group needs it.
- 20–50 people: switch to a mix of x-large + party-sized + a couple of cheese “safe” pies. Confirm cut counts at the store — large-group cuts often differ.
Dietary checklist (call before ordering)
For a group, run this short checklist beforeyou order:
- Any nut allergies? Many doughs and sauces contain trace nuts.
- Gluten-free or celiac? Cross-contact handling matters more than the crust label.
- Vegetarian / vegan options? Confirm whether the brand offers a dairy-free cheese.
- Halal / kosher? Confirm sourcing, not just toppings.
- Pork-free required? Pepperoni, sausage, and bacon are all pork.
- Spice tolerance for kids? Pepperoni varies a lot between brands.
Pizza Code Finder is not a dietary or medical tool. Confirm allergens directly with the restaurant, ideally by calling the specific store rather than relying on the app special-instructions field.
Practical timing
Chain pizza for delivery during peak Friday/Saturday evening often runs 60–90 minute waits. If your group event has a hard start time, ordering carryout 45 minutes before and picking up yourself usually beats waiting on delivery — and it saves the delivery fee /service fee/tip on each order.
