My Homemade Pizza Dough Was Soup One Week and a Brick the Next. Baker's Percentages Fixed It
For about a year, my Friday pizza night was a coin flip. One week the dough was a sticky swamp that glued itself to the counter, the next it was a stiff ball that fought back every time I tried to stretch it. Same recipe, same flour, same oven. The "recipe" was three cups of flour and a cup of water, and I only worked out why it failed when a friend who bakes for a living asked me a simple question: "How many grams is your cup?" I had no idea. This guide is for home cooks who want consistent pizza dough hydration. By the end you'll be able to scale any pizza dough recipe up or down using baker's percentages, and know which numbers to change for Neapolitan, New York or pan-style pies.
Why Do Cups Make Inconsistent Dough?
A cup of flour is not a fixed amount. Scooped straight from the bag it can weigh 140 g or more; spooned lightly and levelled it is closer to 120 g, which is the figure King Arthur Baking uses in its ingredient weight chart. That's a swing of roughly 15 to 20 percent in flour alone, and since water was my only other major ingredient, my dough's wetness changed every week.
Here is what my "three cups plus one cup" recipe did in practice:
| Scoop style | Flour (3 cups) | Water (1 cup) | Water ratio |
|---|---|---|---|
| Light spoon and level | 360 g | 237 g | 66% |
| Heavy scoop | 420 g | 237 g | 56% |
A ten-point swing in hydration is the difference between a sticky dough and a stiff one. The fix is to stop measuring by volume and weigh everything in grams, a habit professional bakers call working in baker's percentages.
What Is Pizza Dough Hydration?
Hydration is the weight of water in a dough expressed as a percentage of the weight of flour. A dough with 600 g of flour and 372 g of water has a hydration of 62%, because 372 ÷ 600 = 0.62.
Baker's percentages express every ingredient this way, with flour always fixed at 100%. That's the standard system taught in professional baking and used across the trade. It means a recipe is really a set of ratios, so it works for one pizza or forty.
Typical styles sit in different hydration bands:
| Style | Hydration | Texture |
|---|---|---|
| Neapolitan | about 62% | Soft, elastic, thin centre |
| New York | about 63% | Chewy, foldable |
| Detroit (pan) | about 75% | Airy, open crumb |
| Roman al taglio | about 80% | Very wet, large bubbles |
Those are typical starting points, not rules. Your flour matters too: higher-protein bread flour absorbs more water than all-purpose, so the same percentage can feel different depending on the bag.
Key Takeaway
Hydration is just water divided by flour, by weight. If your dough feels wrong, change the percentage by 2 or 3 points and keep every other ratio the same, instead of adding "a splash" of water or a "handful" of flour.
How Do You Scale a Recipe With Baker's Percentages?
Scaling works backwards from how many dough balls you want. Add up all the percentages, divide your total dough weight by that sum (as a decimal), and you have the flour weight. Every other ingredient is then flour × its percentage.
Worked example: four Neapolitan pizzas. Four balls of 250 g gives 1,000 g of dough. Using 62% water, 2.8% salt and 0.2% instant dry yeast:
- Sum of percentages: 100 + 62 + 2.8 + 0.2 = 165.0
- Flour: 1,000 ÷ 1.65 = 606 g
- Water: 606 × 0.62 = 376 g
- Salt: 606 × 0.028 = 17 g
- Instant yeast: 606 × 0.002 = 1.2 g
Same method, a New York pie. Say you want four 285 g balls (1,140 g). With 63% water, 2% salt, 3% oil and 0.4% yeast, the sum is 168.4:
- Flour: 1,140 ÷ 1.684 = 677 g (about 5.6 US cups at 120 g each)
- Water: 427 g
- Salt: 13.5 g
- Oil: 20 g
- Yeast: 2.7 g
Metric or imperial doesn't matter, because it's all ratios. In ounces, those four New York balls are about 40 oz of dough, with roughly 24 oz of flour. If you'd rather skip the arithmetic, the Pizza Dough Calculator does exactly this for any style. For general ratio work, the Baker's Percentage Calculator and the Recipe Scaling Calculator cover other doughs.
💡 Pro Tip
Make a little extra: 5% more of everything. Dough sticks to the bowl and your hands, and a small buffer means your last ball is the same size as the first.
How Much Yeast Should You Use?
Yeast is the percentage people guess most often, and it's the easiest to overdo. Small amounts do the job when you give the dough time. A long, cold ferment in the fridge for 24 to 72 hours develops flavour, which is why Neapolitan recipes use as little as 0.2% instant yeast.
Different yeast types are not interchangeable gram for gram. The common baker's conversion, as the calculator's defaults reflect, looks like this at a similar fermentation length:
| Yeast type | Typical % of flour | Notes |
|---|---|---|
| Instant dry (IDY) | 0.2% | Mix straight into flour |
| Active dry (ADY) | 0.25% | Dissolve in warm water first |
| Fresh / cake | 0.6% | Crumble into water |
| Sourdough starter | about 20% | At 100% hydration |
⚠️ Note
Those yeast numbers are for a long cold ferment. For a same-day dough that rises at room temperature in 2 to 4 hours, use several times more (often 1% or more). Warm kitchens speed everything up, so cut back in summer.
Frequently Asked Questions
What hydration should a beginner use for pizza dough?
Start at 60 to 63%. Dough in that range is forgiving and easy to stretch. Move up in 2% steps once you're comfortable handling stickier dough.
Why weigh water instead of measuring it in a jug?
Because it's faster and more accurate. One millilitre of water weighs one gram, so a scale handles both ingredients in the same bowl and avoids reading a jug at eye level.
How big should each dough ball be?
Roughly 250 g for a 10 to 12 inch Neapolitan-style pie and 285 g for a 12 to 14 inch New York pie. Pan styles like Detroit typically use 400 g or more.
Does salt change the dough much?
Yes. Salt tightens gluten and slows yeast, so 2 to 3% is the usual range. Leave it out and dough ferments too fast and tastes flat.
Can I use these percentages with whole-wheat flour?
Yes, but whole-wheat flour absorbs more water, so you may need 3 to 5 points more hydration for the same feel.
Try It Yourself
Consistent dough comes from weighing flour and expressing everything else as a percentage of it. Pick a style, choose how many pizzas you want, and let the numbers scale for you.
