20 kids × 2 tbsp kernels = 2.5 cups total. An air popper handles ½ cup per batch, so plan for 5 batches taking about 15–20 minutes total.
Plan on ¼ cup (2 oz / 57g) of unpopped kernels per person for a standard serving. This yields about 8 cups of popped popcorn, which is a typical movie-theater medium. For a party with other snacks, reduce to 2 tablespoons (1 oz) per person.
| Serving Size | Kernels | Popped Volume | Best For |
|---|---|---|---|
| Small | 2 tbsp (1 oz) | 4 cups | Side snack, party bowl |
| Medium | ¼ cup (2 oz) | 8 cups | Movie night per person |
| Large | ½ cup (4 oz) | 16 cups | Main snack, sharing bowl |
| Party bowl | 1 cup (8 oz) | 32 cups | Crowd serving (4–6 people) |
Use 2–3 tablespoons of oil per ½ cup of kernels for stovetop popping. The ratio is roughly 1 tablespoon of oil per ¼ cup of kernels. Too little oil causes burning; too much makes soggy popcorn. Coconut oil gives movie-theater flavor.
Stovetop popcorn with bulk kernels is the cheapest method at about $0.10–$0.15 per serving. Air-popped is similar. Microwave bags cost $0.40–$0.60 per serving. Movie-theater popcorn costs $5–$9 for the same amount of kernels that cost $0.10 at home.
| Method | Cost per Serving | Flavor Control | Convenience |
|---|---|---|---|
| Stovetop (bulk kernels) | $0.10–$0.15 | Full | Moderate |
| Air popper | $0.08–$0.12 | Full | Easy |
| Microwave bags | $0.40–$0.60 | Limited | Easiest |
| Movie theater | $5.00–$9.00 | None | None (buy only) |
Multiply 1 oz (2 tbsp) of kernels per guest for a party with other snacks, or 2 oz (¼ cup) per guest if popcorn is the main snack. For 20 guests with other food, you need about 2.5 cups of kernels total, yielding roughly 80 cups of popped popcorn.
