Pizza Dough Hydration Explained
Hydration is the single biggest texture lever in pizza dough. Move it five points and you have a different pizza.
Hydration is water weight as a percentage of flour weight. Low 50s: stiff, crackery. High 50s to low 60s: classic New York chew. Mid 60s: Neapolitan puff. 70%+: open, airy, custardy crumb that demands skilled handling and high heat.
The texture map
55%: stiff dough, thin crackery crust, easy to handle. 60%: balanced, the New York zone, foldable with chew. 65%: soft and puffy, the Neapolitan zone, extensible but manageable. 70%: slack and sticky, bakes into an open irregular crumb. 75%+: focaccia territory, nearly pourable, needs a pan or serious skill.
Matching hydration to your oven
Hotter ovens tolerate wetter dough: the intense heat sets the structure before it spreads. In a 550 F home oven, 70 percent dough can bake up gummy inside before the outside finishes. Match wet dough to steel-plus-broiler heat; keep it at 62 to 65 percent for standard home bakes.
Flour sets the ceiling
Strong bread flour drinks 65 to 68 percent happily; all-purpose gets slack above 62. Whole grain flours absorb more but ferment faster. When trying a new flour, start 3 points under your target and add water until the dough feels alive but controllable.
Adjusting by feel
Numbers get you close; hands finish the job. The dough should be tacky but not glued to your fingers after kneading, smooth, and extensible. Dry winter air and humid summers shift effective hydration a point or two, so treat the percentage as a starting bid.

Hydration questions
What does 65% hydration mean?
Hydration is water as a percentage of flour weight. At 65 percent hydration, 1,000 grams of flour takes 650 grams of water.
Is higher hydration better?
Higher hydration yields a more open, airy crumb, but the dough is stickier and harder to shape, and it needs high heat to bake through. Better is matching hydration to your flour, oven, and handling skill.
Why is my high hydration dough sticky?
High hydration dough is inherently sticky. Handle with wet hands, use stretch-and-fold technique instead of kneading, and give it time: the flour hydrates and the dough firms up over the ferment.
Can I convert a recipe to different hydration?
Yes. Keep the flour weight, multiply by your target hydration for the new water weight. Salt and yeast stay the same unless you are also changing the total batch size.
