Hydration is the percentage of water relative to flour, and it's the single number that most defines your crust. It's also the number people chase upward for no reason, then wonder why their pizza got worse.
Hydration by style
| Style | Hydration | Oven temp |
|---|---|---|
| Home oven / New York | 60–63% | 500–550°F |
| Neapolitan | 60–65% | 800–900°F |
| Detroit / pan | 70–75% | 500°F |
| Roman al taglio | 75–85% | 550°F |
| Sicilian | 65–70% | 500°F |
Our pizza dough calculator takes the number of pizzas, ball weight, hydration, salt and yeast, and returns exact gram weights.
What water actually does
Water creates steam. Steam inflates the crumb. That's the whole mechanism — more water means bigger, more open holes and a lighter, chewier texture.
It also makes dough slacker, stickier, and harder to shape, and it changes how the base browns. Every gain has a cost:
| Lower hydration (58–62%) | Higher hydration (70%+) |
|---|---|
| Easy to handle and stretch | Slack, sticky, needs technique |
| Tighter, more uniform crumb | Open, airy, irregular holes |
| Crisper base | Chewier, softer |
| Forgiving of mistakes | Punishes them |
Flour has to keep up
Higher hydration needs stronger flour. Protein content is what holds the water — around 12–14% for high-hydration doughs, and it's why Italian 00 pizza flour and bread flour behave so differently from all-purpose.
Push all-purpose flour to 75% and it can't build enough gluten to hold the structure. The dough goes soupy and no amount of kneading fixes it, because the protein simply isn't there.
Handling wet dough
Wet hands, not floured hands. Counterintuitive and correct — water stops dough sticking to you without drying it out. Flour on your hands ends up in the dough and quietly lowers your hydration.
Stretch and fold instead of kneading. Wet dough can't be kneaded conventionally. Fold it over itself every 30 minutes during the first couple of hours; gluten develops on its own between folds.
Use the autolyse. Mix flour and water only, rest 30 minutes, then add salt and yeast. The flour hydrates fully and gluten starts forming with no work at all. It's free and it makes wet dough noticeably more manageable.
Cold ferment. Cold dough is dramatically easier to handle than room-temperature dough. 24–72 hours in the fridge also builds far better flavour. If high-hydration dough is defeating you, cold fermentation is usually the fix.
Start at 62%
If you're new, or new to a particular oven, start at 62% and change nothing else until you can make that consistently well. Then move in 2% steps.
Most home pizza problems are not hydration problems. They're oven temperature problems, or under-fermentation, or a cold stone. Raising hydration to fix those makes everything harder while fixing nothing.

Frequently Asked Questions
What hydration should pizza dough be?
Around 60 to 63% for a home oven, 60 to 65% for Neapolitan in a very hot oven, and 70 to 75% for pan styles. Match hydration to your oven temperature.
Is higher hydration pizza dough better?
No, just different. Higher hydration gives an open, chewy crumb but needs high heat, strong flour and better technique. In a 500°F home oven it often makes pizza worse.
Why is my high hydration dough soggy?
Usually the oven isn't hot enough to turn the water to steam quickly, or the flour is too weak to hold the structure. Use bread or 00 flour and drop the hydration.
How do you handle sticky pizza dough?
Wet your hands rather than flouring them, use stretch-and-folds instead of kneading, try an autolyse, and cold ferment the dough — cold dough handles far more easily.
