How much pasta per person
Dry pasta portions typically run 85–115 g (3–4 oz) per person as a main course, or about 55–85 g (2–3 oz) as a side or starter portion. Multiply your chosen per-person amount by the number of guests to get the total dry weight to cook.
Shape affects perceived portion size — long pasta like spaghetti and short pasta like penne have different densities in a measuring cup, so weighing dry pasta on a scale is more reliable than eyeballing a handful. Cooked pasta roughly doubles in weight after absorbing water.
Example: for 6 guests at 100 g per person (a common main-course default), you need 600 g of dry pasta total, which works out to about 21.2 oz — close to one and a half standard 1 lb (454 g) boxes.
Common questions
How much dry pasta is one serving?
85–115 g (3–4 oz) is typical for a main course; 55–85 g (2–3 oz) works for a side dish or starter. Adjust based on appetite and how many other courses you are serving.
Does cooked pasta weigh the same as dry pasta?
No — pasta absorbs water and roughly doubles in weight when cooked. This calculator estimates dry (uncooked) weight to buy and cook, not the finished cooked weight.
