Pasta Dough Calculator
This calculator scales fresh pasta dough — flour and eggs — based on how many servings you need.
It uses the classic Italian ratio of 100g flour to 1 egg per serving.
It's based on the traditional Italian ratio of 100g flour per large egg per serving, a formula developed to balance enough protein and moisture for a dough that's elastic without being sticky.

The Science Behind It
The 100g-flour-to-1-egg ratio is a traditional Italian pasta formula that balances enough protein and moisture for a dough that's elastic but not sticky. Egg yolks specifically contribute fat that makes the pasta tender. Source: La Cucina Italiana.
La Cucina Italiana's traditional pasta guidance documents the 100g-flour-to-1-egg ratio as a regional standard, though some Italian regions historically favor variations using more egg yolks for a richer dough.
Egg yolks contribute fat and emulsifiers that make fresh pasta more tender and easier to roll thin, which is why some enriched pasta recipes substitute additional yolks for whole eggs.
Where This Shows Up
Home cooks preparing a dinner party or family gathering use this calculator to scale a fresh pasta recipe precisely to their expected guest count.
Bakers and pasta enthusiasts experimenting with different flour types, like using semolina alongside all-purpose flour, rely on this base ratio as a starting point before adjusting for the new flour's absorption.
Italian cooking classes frequently teach the 100g-per-egg ratio as a foundational lesson, since it lets students scale a fresh pasta recipe to any group size without memorizing multiple formulas.
A Worked Example
Say you're cooking for 6 people at roughly 100g of fresh pasta per serving. Total flour needed is about 600g, which at the classic ratio of 100g flour per egg means using 6 large eggs — the whole recipe scales directly from the per-serving flour target.
Whole Egg vs Egg Yolk Pasta
| Whole Egg Pasta | Egg Yolk Pasta | |
|---|---|---|
| Ratio | 100g flour : 1 whole egg | 100g flour : 2 yolks |
| Richness | Standard | Richer, more tender |
| Color | Lighter yellow | Deeper yellow |
Common Mistakes
- Using small or medium eggs without adjusting the ratio, since the classic formula assumes large eggs as the standard.
- Adding too much flour while kneading to compensate for a sticky dough, which can make the finished pasta tough instead of tender.
- Not resting the dough after mixing, which prevents the gluten from relaxing enough for easy rolling.
- Rolling pasta dough immediately after mixing without a rest period, which makes it harder to roll thin and can result in a tougher final texture.
- Not adjusting flour type when substituting '00' flour for all-purpose, since the two absorb liquid differently despite the same egg ratio.

Frequently Asked Questions
How much pasta dough do I need per person?+
About 100g of fresh pasta dough per serving is standard.
Can I use only egg yolks for pasta dough?+
Yes, some recipes use all yolks for a richer, more tender pasta — typically 2 yolks per 100g of flour instead of 1 whole egg.
Does this ratio work for all pasta shapes?+
Yes, the base dough formula is the same regardless of shape — differences come from how the dough is rolled and cut afterward.
Can I make pasta dough without eggs?+
Yes, many regional Italian styles use just flour and water instead, though the texture and richness differ from egg-based pasta.
Does altitude affect fresh pasta dough?+
Minimally compared to baked goods, since pasta dough doesn't rely on leavening — altitude mainly affects boiling time for the cooked pasta.
