Portion calculator

A standard adult portion is 80 g of dry pasta or rice, 130 g of meat or fish, 200 g of vegetables and 50 g of bread. Children count as 0.5 to 0.9 of an adult depending on age. Four people therefore need about 320 g of pasta and 520 g of protein.

Formula and source

Equivalent adults = adults plus children times 0.7, multiplied by the appetite factor. Quantities come from multiplying equivalent adults by the standard portion of each category.

Source: Standard portion sizes from the Italian LARN reference intake levels.

Frequently asked questions

Are the quantities raw or cooked?

Raw. Pasta and rice roughly triple in weight when cooked, meat and fish lose between twenty and thirty per cent.

How do I plan next-day lunchboxes?

Add one equivalent adult for each lunchbox: you cook once and the quantity is already right.
