Pasta Weight Converter

Pasta roughly doubles in weight when cooked.

Dry to cooked weight ratio:

That last row surprises people. Fresh pasta already contains water, so there is far less left to absorb, and a 250 g packet of fresh tagliatelle feeds about two, not four.

Standard servings:

• 1 serving dry pasta = 56 g (2 oz) = 112 g cooked
• A main course rather than a side: 100 g dry is the Italian standard
• 1 pound (454 g) dry = about 8 servings, or 4 generous mains

Common dry amounts:

• 100 g dry = 200 g cooked = 3.5 oz dry
• 250 g dry = 500 g cooked = 8.8 oz dry
• 500 g dry = 1,000 g cooked = 1.1 lbs dry

Water and salt, which matter more than most people think:

• 1 litre of water per 100 g of dry pasta. Less than that and the starch concentration climbs, the water cools when the pasta goes in, and the shapes stick.
• 7 to 10 g of salt per litre. That is roughly a level tablespoon of table salt for a 4 litre pot. It sounds like a lot, and most of it goes down the drain, but pasta cannot be salted after the fact.
• Add the salt once the water boils, and never add oil. Oil coats the pasta and stops sauce clinging to it.

Tips:

• Weigh pasta dry for best accuracy.
• Cooked weight varies with cook time. Al dente to soft is a difference of 15 to 20% in finished weight.
• Save a cup of the cooking water before draining. The starch in it is what turns a thin sauce glossy.

Pasta is the food people most reliably over-portion, because dry pasta looks like so little. It roughly doubles in weight as it absorbs water, so a modest 2-ounce dry serving becomes a full plate once cooked. Eyeballing straight from the box almost always overshoots, which is how a “quick dinner for two” turns into leftovers for days.

Weighing is the only consistent way to portion it, because volume measures lie for pasta. A cup of penne and a cup of macaroni hold very different amounts, since the shapes pack differently, and long pasta won’t sit in a cup at all. That’s why the old tricks exist: a bundle of dry spaghetti about the diameter of a US quarter is roughly one serving. Handy in a pinch, but a kitchen scale set to 2 ounces for a side or 4 for a main is far more reliable than any guess.
