Never run out of marshmallows halfway through a campfire s'mores session again - this calculator breaks down exactly what you need based on group size and expected s'mores per person.
Formula (Classic S'more Ratio)
One s'more = 1 marshmallow + 2 graham cracker halves + 2 chocolate squares
Total S'mores = People x S'mores Per Person
Example
8 people, expecting 2.5 s'mores each:
Total = 20 s'mores → 20 marshmallows, 40 graham cracker halves, 40 chocolate squares
How Many Per Person?
Planning for roughly 2-3 s'mores per person is a common camping and campfire party guideline - most people want at least a second one once the first has been successfully toasted, and it's generally easier to have a small surplus than to run short mid-campfire when marshmallow cravings are running high.
