Confetti Calculator — How Much Confetti You Need
Calculate how much confetti you need for throwing, table scatter, or both at your celebration.
How We Calculate This
This calculator estimates confetti quantities based on guest numbers and usage type.
The formula
Throwing confetti = guests × 15g per person
Table confetti = number of tables × 20g per table
Pack sizes vary by type: paper confetti typically comes in 50g packs, metallic in 25g, and biodegradable/petal in 30g. Packs needed are rounded up to ensure you have enough.
Frequently Asked Questions
