Planning Food for 15 Guests
Ordering pizza for 15 people can be tricky. You don't want anyone to go hungry, but you also don't want 10 boxes of leftovers.
Tips for Small Gatherings
- Personal Preferences: With only 15 guests, you can actually ask everyone for their favorite topping!
- Quality over Quantity: Since you're ordering fewer pizzas, consider upgrading to a premium local pizzeria instead of a chain.
- Leftovers: Plan for about 2 slices per person, but ordering one extra pizza for late-night snacking is never a bad idea.
Drinks & Sides
Don't forget the drinks! Our calculator estimates you'll need soda/water for a 3-hour party. If you're serving alcohol, a good rule of thumb is 1.5 drinks per person per hour.
Frequently Asked Questions
How many pizzas do I need for 15 people?
For 15 guests, you should order approximately 5 to 6 large pizzas. This assumes an average of 2-3 slices per person.
How many slices of pizza per person?
A good rule of thumb is 2.5 slices per adult and 1.5 to 2 slices per child. For a party lasting more than 2 hours, round up to 3 slices per adult to be safe.
What size cake do I need for 15 people?
For a small group of 15, a Quarter Sheet Cake (serves ~20) or a round 10-inch cake is sufficient.
