How much pasta per person?
For a main dish, plan on 75–100 g (2.6–3.5 oz) of dry pasta per adult. Light eaters need closer to 75 g; hungry guests can eat 125 g. Kids count as roughly 60% of an adult portion.
Main dish versus side dish
The calculator uses 100 g dry pasta per adult for a standard main dish and 60 g per adult when pasta is one side among other foods. Appetite and one selected leftover allowance are applied after that choice.
Dry pasta vs cooked pasta
Dry pasta roughly 2.25× in weight when cooked. So 100 g dry becomes about 225 g cooked. Use dry weight when shopping and cooked weight when serving.
Worked example: pasta for 100 guests
With 100 adults, main-dish mode, normal appetite and no leftovers, the engine calculates 10 kg (22 lb) dry pasta and about 22.5 kg (49.6 lb) cooked. The default 10% leftover setting raises the dry requirement to 11 kg and rounds the purchase quantity to practical 250 g increments. Sauce and Parmesan use the same guest, appetite and leftover selections.
Tips for serving pasta at parties
- Cook in big batches and keep warm with a splash of pasta water.
