Frequently Asked Questions
How much food do I need for a party?
It depends on guest numbers, whether food replaces a meal, event length and portion style. Use the planner to turn those into planning ranges for mains, sides, snacks and dessert.
How do you calculate food for adults and children?
We use simple planning multipliers (adult, teen, child, young child) to create adult-equivalent portions. These are planning aids, not biological precision.
How many pizzas do I need for a party?
Enter guests, slices per person and slices per pizza. Required slices are divided by slices per pizza and rounded up. You can add an optional extra pizza buffer.
How much cake do I need?
Enter how many guests will eat cake and a serving size. If you know how many servings your cake provides, we show whether you are short and by roughly how much.
How many drinks should I buy?
Drink estimates use guest count, duration, serving size and container size you enter. Longer events and warmer/outdoor settings increase water ranges.
Should I plan extra food?
Optional buffers (0%, 5%, 10% or custom) help with late changes. There is no universal rule — choose what fits your event.
Can I use confirmed RSVP numbers?
Yes. If My Event has estimated and confirmed counts, you can plan for estimated, confirmed, confirmed + buffer, or a custom number.
Can I use the planner for weddings?
Yes. Sit-down meal mode can show meal-choice counts from RSVPs when available, plus cake and evening snack planning.
Can I use it for children’s parties?
Yes. Children’s party food mode and quick calculators cover pizza, snacks, cake and juice-style planning.
Are the quantities guaranteed?
No. Quantities are planning estimates only. Appetite and serving style vary — always adjust for your guests.
Does the planner provide catering or nutrition advice?
It provides quantity planning and optional high-level serving tips. It does not provide medical nutrition advice, allergy diagnosis or catering quotes.
Can I save the plan to My Event?
Yes. Save Food Plan to My Event stores a summary on your active event. Calculators work without creating an event.
Food and drink quantities are planning estimates only. Appetite, serving sizes, event duration and catering style vary. Always adjust the plan for your guests and confirm specialist dietary/allergen requirements directly with your caterer or food provider.
