A pasta serving calculator converts the number of people and pasta type into exact dry pasta amounts in grams and ounces. Different pasta shapes have different serving weights — short pasta like penne packs more tightly than long pasta like spaghetti.
Water: use at least 4 quarts (4L) per pound of pasta. Salt generously — water should taste like the sea.
Cooking Time Reference by Pasta Type
| Pasta | Time (al dente) | 1 serving (dry) |
|---|---|---|
| Spaghetti | 8–10 min | 57g / 2 oz |
| Penne | 10–12 min | 57g / 2 oz |
| Fusilli | 10–12 min | 57g / 2 oz |
| Fettuccine | 8–10 min | 57g / 2 oz |
| Orzo | 7–9 min | 57g / 2 oz |
| Lasagna sheets | 10–12 min | 75g / 2.6 oz |
How Much Pasta to Cook Per Person
The standard restaurant portion for dry pasta is 2 oz (57g) per person as a main course. This becomes about 4 oz (113g) cooked. For heartier appetites or if the pasta is the only dish, use 3 oz (85g) per person.
Cooking Pasta Correctly
Use a large pot with plenty of water — at least 4 quarts per pound of pasta. Salt the water generously after it boils (about 1 tablespoon per 4 quarts). Don't add oil — it prevents sauce from adhering. Cook al dente (firm to the bite) and finish in the sauce for 1-2 minutes.
Reserve Pasta Water
Before draining, save 1 cup of starchy cooking water. Add it tablespoon by tablespoon when tossing pasta with sauce to create a silky, cohesive coating. This is the professional technique that makes restaurant pasta different from home pasta.

How much does pasta expand when cooked?
Dry pasta roughly doubles in weight — 2 oz dry becomes about 4 oz cooked. Volume expands significantly: 1 cup of dry spaghetti becomes about 2 cups cooked. Shapes vary; fusilli and penne expand more.
How do I measure spaghetti without a scale?
A bundle of spaghetti that fits through a quarter-sized circle (roughly the size of a 25-cent coin) is about 2 oz, one serving. Use a spaghetti measure tool or a hole in a spoon for consistency.
