Planning Food for 100 Guests
Ordering pizza for 100 people can be tricky. You don't want anyone to go hungry, but you also don't want 10 boxes of leftovers.
Tips for Large Groups (100+ People)
- Variety is Key: For a group of 100, you should order at least 3-4 different topping combinations.
- The "Safe" Ratio: Stick to 40% Cheese, 40% Pepperoni, and 20% Veggie/Specialty. This pleases the crowd most effectively.
- Delivery Timing: For 100 guests, ask the pizza place to "double cut" the slices (party cut) if you're serving appetizers too.
- Sheet Cakes: For 100 people, a full sheet cake is usually the most cost-effective dessert option.
Drinks & Sides
Don't forget the drinks! Our calculator estimates you'll need soda/water for a 4-hour party. If you're serving alcohol, a good rule of thumb is 1.5 drinks per person per hour.
