Bread Hydration Guide
How hydration percentage affects dough character and bread types.
| Hydration % | Dough Feel | Bread Types | Skill Level |
|---|---|---|---|
| 50-55% | Very stiff, easy to shape | Bagels, pretzels | Beginner |
| 56-60% | Firm, smooth | Sandwich bread, rolls | Beginner |
| 61-65% | Slightly tacky, workable | French bread, pizza | Beginner |
| 66-70% | Tacky, moderate stickiness | Country bread, sourdough | Intermediate |
| 71-75% | Sticky, extensible | Artisan sourdough, batard | Intermediate |
| 76-80% | Very sticky, slack | Ciabatta, focaccia | Advanced |
| 81-85% | Extremely wet, batter-like | High-hydration ciabatta | Advanced |
| 86-90%+ | Pourable, very wet | Focaccia, pan breads | Expert |

How to Convert Oven Recipes to Air Fryer
Hydration is the most important ratio in bread baking. It's the total water weight divided by total flour weight, expressed as a percentage. Getting it right determines your crumb structure, crust, and workability.
The basic rule:
- Hydration % = (total liquid ÷ total flour) × 100
- Sourdough starter contributes both flour and water — a 100% hydration starter is 50/50
- Milk counts as ~87% water by weight; eggs count as ~75% water
- Higher hydration = more open crumb but stickier, harder-to-handle dough
This calculator accounts for all liquid sources including sourdough starter (at any hydration level), milk, and eggs. It gives you the true hydration of your final dough.

Frequently Asked Questions
What is bread hydration?
Bread hydration is the ratio of total water to total flour in a dough, expressed as a percentage. A dough with 700g water and 1000g flour has 70% hydration. It's the single most important variable in determining bread texture.
What hydration should I use for sourdough?
Most sourdough recipes use 70-78% hydration. Beginners should start around 70% which is easier to handle. As you gain experience, try 75-80% for more open crumb. Hydration above 80% requires advanced shaping skills.
How does sourdough starter affect hydration?
Starter contains both flour and water. A 100% hydration starter (equal parts flour and water) adds equal amounts of each. A 200g starter at 100% hydration adds 100g flour and 100g water to your dough's totals.
Does milk count as water for hydration?
Milk is about 87% water by weight. So 100g of milk contributes roughly 87g of liquid to your hydration calculation. The remaining 13% is fat, protein, and sugar which affect texture but not hydration math.
Why is my high-hydration dough so sticky?
That's normal. High-hydration doughs (75%+) are inherently sticky. Use wet hands, a bench scraper, and techniques like stretch-and-fold instead of kneading. The stickiness reduces as gluten develops during bulk fermentation.
What hydration is best for sandwich bread?
Sandwich bread works best at 60-65% hydration. This produces a soft, tight crumb that slices well and holds fillings. Enriched doughs (with butter, eggs, milk) can go lower because the fats add tenderness.
