Frequently asked questions
Multiply the trick-or-treaters you expect by the pieces you hand each (2 is typical), then add a 10–20% buffer. Eighty visitors at 2 pieces plus 15% needs about 184 pieces.
It depends on the street more than the town: decorated, well-lit blocks near schools can see 100+, quiet cul-de-sacs under 20. Last year's count — or a neighbour's — is the best guide.
Fun-size bags commonly hold 30–60 pieces; the calculator defaults to 40. Check the count on the bag, not just its weight, before you shop.
Turn off the porch light — the universal signal that a house is done for the night. Buying one extra bag is cheaper than a second trip.
Skip anything homemade or unwrapped, and consider a few non-candy or allergen-friendly options (glow sticks, stickers) for kids who cannot have common allergens.
