What is the butter-to-dough ratio for croissants?

Traditional French croissants use a butter block that is about half the weight of the base dough (50% ratio). This gives the classic flaky, buttery layers. Some recipes use slightly less (40%) for a lighter result or more (60%) for an ultra-buttery pastry.

How many folds do croissants need?

Classic croissants use 3 single (letter) folds, creating 27 layers of dough and butter. Pain au chocolat uses the same lamination. Danish pastries can use 3 single folds or 2 double (book) folds. Too many folds can cause the butter to blend into the dough rather than staying as distinct layers.

What temperature should the butter be?

The butter block should be cool but pliable — about 15°C. If the butter is too cold, it will crack and break through the dough layers. If too warm, it will melt into the dough and you will lose the distinct layers. Work in a cool kitchen and chill the dough between folds.

How long does laminated dough take to make?

From start to baked croissants, expect 12-24 hours. This includes making the dough (30 min), chilling (2+ hours), 3 rounds of folding with resting between each (3-4 hours), shaping, final proof (1-2 hours), and baking (15-20 min). Many bakers do the folding one day and bake the next morning.

How We Calculate This

This calculator works backwards from the number of pieces and desired piece weight to determine the total dough needed (with 10% added for trimming waste). It then splits this into base dough and butter block using the butter-to-dough ratio.

The Calculation

Total dough = Pieces x Weight x 1.1 (trimming)
Base dough = Total / (1 + butter ratio)
Butter block = Total - Base dough
Base dough ingredients use baker's percentages based on flour weight
