Dry to Cooked Pasta Converter

For most pasta shapes, 1 cup of dry pasta yields roughly 2 cups of cooked pasta. So you'd need about 1 cup (approximately 100g) of dry pasta to make 2 cups cooked. Long pasta like spaghetti has a similar ratio — about 85–100g dry produces 2 cups cooked.

Short pasta like penne roughly doubles in volume when cooked. Using 4 cups of dry penne will yield approximately 8 cups of cooked pasta, which is enough for about 4–6 generous servings.

Not exactly. Short pasta (like penne) and long pasta (like linguine) have slightly different expansion ratios due to their shape and density. Penne tends to expand more in volume, while linguine absorbs water similarly by weight. By weight, the ratio is close, but by cup volume they can differ slightly.

Spaghetti roughly doubles in volume when cooked. To get 4 cups of cooked spaghetti you'd need about 2 cups (around 180–200g) of dry spaghetti. Use our calculator above for a precise conversion based on grams or ounces.

Most pasta absorbs about 1.8 to 2.2 times its dry weight in water during cooking. So 100g of dry pasta typically yields around 200–220g of cooked pasta. The exact ratio varies slightly by pasta shape and cooking time.

A standard dry pasta serving is typically 75–85g per person for a main course, or about 50–60g as a side dish. When cooked, this yields roughly 150–200g of pasta per person.

Yes, slightly. Thinner pasta like angel hair absorbs water and expands faster, while thicker shapes like rigatoni or penne may take longer but achieve a similar final ratio. By weight, most pasta expands to roughly 2–2.5x its dry weight regardless of shape.

Absolutely. Just enter the total dry pasta amount you plan to cook (e.g. 500g or 1000g), set your serving size, and the calculator will tell you the total cooked yield and how many servings it produces. Great for meal prepping or cooking for large groups.
