How Much Pasta to Cook
The standard serving size for dry pasta in Italy is 80 grams per person for a first course (primo) and 100 grams for a main course. In the US and UK, servings tend to be larger — around 100–115g per person for a main.
Dry pasta roughly doubles in weight when cooked — 100g dry becomes approximately 200–230g cooked, depending on the pasta shape and cooking time. Plan for leftovers by multiplying your dry amount by 2.2–2.5 for the final cooked weight.
Frequently Asked Questions
How much spaghetti per person?
For spaghetti as a main course, plan for 75–100g of dry spaghetti per person. If you're feeding particularly hungry adults or using it as the only main course, go for 100g per person.
How much pasta for 4 people?
For 4 adults as a main course, use 300–400g of dry pasta. For a lighter lunch or as a side, 250–300g is sufficient. Always cook slightly more than you think — pasta is easy to reheat.
Does the pasta shape affect portion size?
The amount by weight stays the same, but cups or volume measurements differ significantly by shape. Weight (grams) is the most reliable way to measure pasta portions.
How much does dry pasta expand when cooked?
Dry pasta absorbs water and expands to about 2.2–2.5 times its original weight. 100g of dry penne becomes approximately 220–250g of cooked pasta.
