The Simple Math Behind Hydration
Flour is always the baseline, counted as 100%. Every other ingredient gets measured as a percentage of that flour's weight. So if you have 500 grams of flour and a recipe calls for 65% hydration, you need 325 grams of water (500 ร 0.65). That's it โ no advanced math, just a ratio.
This system, called baker's percentages, is why professional recipes scale so easily. Whether you're making 2 pizzas or 20, the percentages stay identical โ only the total amounts change. Our pizza dough calculator does exactly this math for you across four different pizza styles.
What Changes as Hydration Goes Up or Down
Low hydration (55-60%) makes a firm, easy-to-stretch dough that's forgiving for beginners. It holds its shape well but bakes up a bit denser and less airy inside.
Medium hydration (60-65%) is the sweet spot most home pizza makers land on โ it's the range most Neapolitan and New York recipes use, including the calculator's own presets. You get a nice balance of open, airy crumb without the dough being a nightmare to handle.
High hydration (70%+) is where Detroit and Sicilian styles live. This dough is genuinely sticky and looks more like thick batter than traditional dough right up until it goes in the pan. That stickiness is exactly why those styles get pressed into an oiled pan instead of stretched by hand โ trying to hand-stretch a 72% hydration dough is a losing battle that ends with dough stuck to everything in your kitchen.
Why Higher Hydration Isn't Automatically Better
It's tempting to think more water always equals a better pizza, since high-hydration dough gets so much hype online. It's not that simple. Higher hydration doughs are harder to shape, ferment differently, and can genuinely overwhelm a beginner who hasn't built the hand-feel for sticky dough yet.
The right hydration is the one that matches your style and your comfort level, not the highest number you can find. A well-made 60% hydration Neapolitan pizza beats a poorly-handled 75% hydration one every time. Master a moderate hydration first, then experiment upward once handling wet dough feels natural instead of frustrating.
One more honest tip: hydration also depends on your flour. Different flours absorb water differently, so a 65% hydration dough with one brand of flour might feel noticeably different with another. Treat percentages as a strong starting point, not gospel, and adjust by feel as you get more reps in.
