How much food for a kids birthday party?
The honest answer is less than most lists tell you, and the reason is the clock rather than the guest count. A party that starts at two in the afternoon and runs two hours misses lunch and misses dinner. Every child arrives fed and leaves in time to eat again.
The answer
12 children aged 3 to 5 and 4 adults, 2:00 PM for 2 hours.
12portions
This party misses lunch and dinner, so snacks and cake are enough. Ordering a full meal here is the most common overspend.
Our rule
16cupcakes
12 for the children plus 2 spares, and about half the 4 adults take one.
Our rule
33drinks
One cup per child per hour over 2 hours, minimum 2 each, plus 0.75 an hour for the adults, then a 10% buffer.

Two o clock is why this list is short
Most calculators take the number of guests and multiply. That produces a meal for a party that does not span one, which is the single most expensive mistake at a kids party. Before you order anything, check whether your party genuinely overlaps a mealtime. If it starts at noon the answer changes completely, and there is a page for that below.
This is a snack party, not a meal.

Your party is not this party
Change the guest count, the ages, the start time or the weather and the whole list moves. The calculator opens on the party above, so you can adjust it rather than start again.
