Hydration is the single most important number in a pizza dough recipe. I don't say that lightly. Get it wrong and nothing else matters, not the 72-hour ferment, not the Caputo 00, not the $200 steel. Get it right and you can mostly ignore everything else and still pull off a great pie.
This is the guide I wish existed when I was figuring this out at home. The exact hydration I use for every style, why each number lands where it does, and the fixes for the mistakes I made so you don't have to make them. Bookmark it. Refer back when a dough goes sideways.
Hydration is the ratio of water to flour, expressed as a percentage. If a recipe calls for 1000g flour and 650g water, that's 65% hydration. Flour is always 100% in baker's math, every other ingredient (water, salt, yeast, oil) gets measured relative to it.
Why does this matter? Because water is what activates gluten, controls crumb structure, and determines how much steam gets produced in the oven. More water = more open, airy crumb. Less water = denser, chewier, crispier.
Bookmark this. Every pizza style I make lives somewhere in this range.
Those are the ranges. Where you land inside the range comes down to three things: how hot your oven gets, how long you're fermenting, and what flour you're using.
Dense, crisp, easy to handle. The dough holds its shape, stretches without tearing, and bakes into a cracker-thin crust. Great for beginners. Think: bar pie, tavern pizza, thin-crust NY. Low-hydration doughs don't produce big puffy airy cornicione, they produce snap.
This is where 90% of home pizza lives. 65% is the universal "can't mess it up" starting point. Good stretch, decent crumb opening, works in a home oven at 550°F with a Baking Steel. Every single NY-style recipe on this site lives here.
Big puffy cornicione, large irregular holes in the crumb, soft and airy interior. Trickier to handle, the dough is sticky and needs stretch-and-fold technique instead of kneading. Requires a 48-72 hour cold ferment to build enough gluten strength to handle the water. Detroit and Sicilian live here.
Rome al taglio, focaccia, experimental territory. These doughs are essentially batters that you fold multiple times over hours. Massive open crumb. Not something I'd suggest until you've nailed the 65-72% range first.
A question I get constantly: "I want to try a higher hydration, how do I actually do it?" Here's the playbook.
Bread flour has 12-13% protein. That's your baseline. If you want to go above 68% hydration, switch to high-gluten flour (14%+) like King Arthur Special or Central Milling Organic. More protein = more gluten network = more water the dough can absorb without falling apart.
Cold fermentation (48-72 hours at 38-40°F) lets gluten fully hydrate and organize slowly. You can push hydration 2-5% higher with a long cold ferment vs a same-day dough. If you're stuck at 63% same-day, you can comfortably hit 67% with a 48-hour cold ferment using the same flour.
Kneading a 72% hydration dough on a counter is miserable. The gluten isn't developed yet and the dough just sticks to everything. Instead: mix everything in a bowl, let it rest 20 minutes (autolyse), then do 4 stretch-and-folds every 15-30 minutes for the first 1.5 hours. Wet your hands to stop sticking. The dough will transform from a sloppy mess into a smooth elastic ball without you kneading once.
Bump it 1-2% at a time. Don't jump from 62% to 75%, you'll fail and get discouraged. Go 62 → 64 → 66 → 68 over a few weekend bakes. You'll feel the dough change each time and learn what's happening.
A lot of pizza blogs recommend 70%+ hydration for everything. If you have a 900°F outdoor pizza oven, that's fine. In a 550°F home oven, it's often wrong. Here's why.
At 550°F, water in the dough takes longer to turn to steam and escape. A 75% hydration dough in a 550°F oven comes out gummy in the middle even when the outside looks done. The crust doesn't have enough direct heat intensity to drive all that water out fast enough.
The home-oven sweet spot is 63-67%. That's my range for every round-pie recipe on this site. Pan pizzas like Detroit and Sicilian get away with higher hydration because they bake longer in oil-coated pans at slightly lower temperatures (500-525°F), which gives water time to evaporate properly.
These are the specific hydration percentages I use in my home oven (550°F, Baking Steel top rack). If you're following any recipe on this site, these are already dialed in, but here they are as quick reference.
63%. That's the number I use every time. It's the sweet spot where the dough is still workable by hand, produces a classic chewy NY slice, and bakes cleanly in a home oven at 550°F. For the full recipe see /recipes/perfect-plain-cheese-pizza.
It depends on the style. For a round NY-style pie at 550°F, yes, you'll get a gummy crumb. For a pan pizza like Detroit or Sicilian, 70-72% is perfect because the longer bake time lets water evaporate properly.
Flour is 100%. Every other ingredient is a percentage of the flour weight. For 1000g flour at 65% hydration: 1000 × 0.65 = 650g water. Salt at 2% = 20g. Yeast at 0.4% = 4g. That's the entire math.
No. Pizza dough is the one place where weight accuracy actually matters. A cheap $10 kitchen scale pays for itself on your first dough.
55% for a Chicago tavern or cracker-style pizza. Below that the dough won't properly hydrate and you'll get a tough, pasty texture no matter how long you ferment.
