Pasta Weights, Conversions & Servings (With Calculator)

In this ultimate one-stop guide to pasta weights and conversions, you’ll find a calculator and charts to help you work out any conversion weights of pasta.

As well as this, I’ll help you to quickly convert before and after cooking weights and give you the tools you need to work out how much pasta you need to feed a certain amount of people.

Pasta Weights Before & After Cooking (in Grams & Ounces)

When it comes to pasta weights and servings, one of the most common questions is around before and after cooking weights because dry pasta increases in weight considerably when cooked.

I have experimented with cooking various types and shapes of dry pasta and weighing it before and after to find out how much it increases when cooked to try and get a definitive answer on how to calculate the difference.

The results were; there isn’t an exact amount that pasta increases by when it’s cooked because different shapes absorb more water than others, but I was able to get an average increase amount that can be used to estimate before and after cooking weights.

Pasta increases in weight when cooked by anything from 2 times the original weight up to 2.5 times the original weight. Based on this, a good amount to calculate an average pasta weight increase once cooked is 2.25 times the original weight.

Another way to calculate this figure is by adding 125% to the original dry pasta weight – you can use the chart below to see what this increase looks like for various servings.

How to Convert Cooked Pasta Weights to Dry Weights

In some cases, you might need to convert cooked pasta weights back to dry weights; for example, if a recipe is based on cooked weights or calories, information is based on dry pasta weights.

You can calculate the average dry weight of the pasta by dividing the cooked weight by 2.25; for example, if your cooked pasta weight is 100g, the dry weight will be about 40g.

Please note this is based on averages, and the amount of water pasta absorbs varies between shapes and will depend on how long the pasta is cooked for.

Pasta Weight Per Person

Recommended serving sizes vary depending on where you look and the country you live in; for example, in the USA, the serving recommendation of dry pasta is 2oz/56g, whereas, in the UK, it’s 75-85g.

To get an idea of what a weight of pasta looks like, the image below shows 50g/1.76oz of elbow/spiral pasta before and after cooking. As you can see, a 50g portion is relatively small and wouldn’t be enough for a main meal portion.

Based on this, I’ve categorized portion sizes into small, medium, large and extra-large so you can work out how much pasta you need per person depending on the appetites of the people you’re feeding.

The table below shows the dry to cooked pasta weights for each serving size, based on an average increase of 2.25 the original weight (see above).
