Hydration sounds technical. However, it’s one of the simplest ways to change the texture, structure, and overall feel of your Neapolitan pizza crust.
In this guide, you’ll learn what hydration means, why it matters, and how to choose a hydration level that fits your flour, environment, and pizza goals.

What is “hydration” in pizza dough?
Hydration is simply the percentage of water compared to flour by weight.
For example:
- 1000g flour + 600g water = 60% hydration
- 1000g flour + 650g water = 65% hydration
- 1000g flour + 700g water = 70% hydration
Because it’s a ratio, hydration stays consistent even when you scale your dough recipe up or down.
Why hydration matters for Neapolitan pizza
Hydration affects both how your dough behaves and how your pizza bakes.
As hydration changes, you’ll notice differences in:
- Dough handling (easy vs sticky)
- Oven spring (how much the crust puffs)
- Crumb openness (airy holes vs tight crumb)
- Bake speed and char
- Overall crust texture
In other words, hydration influences both the process and the final bite.
Higher hydration usually creates a lighter, airier crust
When hydration is dialed in properly, the crust becomes lighter, softer, and more cloud-like around the edges.
The additional water allows the dough to expand more during the bake, creating a more open cornicione with better oven spring and leopard spotting.
However, higher hydration also increases difficulty.
The dough can feel:
- stickier
- softer
- harder to control
- more sensitive to temperature
If rushed, it can easily lose shape during stretching and preparation.
Lower hydration is easier to manage
At around 58–62%, the dough feels tighter, firmer, and more forgiving.
This makes it a great range for:
- warmer kitchens
- beginners
- home pizzaiolos
- doughs that over-ferment easily
However, if hydration becomes too low, the crust can bake denser and lose that signature airy Neapolitan texture.
What hydration should you use for Neapolitan pizza?
There isn’t one “perfect” hydration percentage.
The best range depends on:
- your flour
- kitchen temperature
- fermentation style
- experience level
- oven setup
A practical starting point: 62–65%
For many home and professional setups, 62–65% hydration is a very balanced range.
It:
- stretches well
- still holds shape
- produces a light crust
- remains manageable during service
When 66–70% hydration makes sense
Higher hydration works best when:
- your flour absorbs water well
- your kitchen temperature is controlled
- your fermentation is stable
- you want a softer, more open crumb
This range can create an extremely airy and delicate crust when handled properly.
When 58–61% is the better choice
Slightly lower hydration is often better if:
- your kitchen runs hot and humid
- your dough overproofs quickly
- the dough becomes too sticky during service
- stretching becomes difficult
In warmer climates like Singapore, lowering hydration slightly can make the workflow much easier and more stable.
What we’ve learned in our own kitchen
One thing we’ve learned over time is that hydration behaves very differently depending on temperature, fermentation timing, and even the time of day.
In warmer kitchens, dough softens much faster during service. A hydration percentage that feels perfect in the morning can feel significantly looser later in the day once fermentation progresses further.
That’s why hydration is never just about “adding more water.” It’s about balancing the entire dough system properly.
Hydration is not just “add more water”
Hydration works together with:
- flour strength
- fermentation
- salt
- temperature
- dough handling
Changing one variable often changes the behavior of everything else.
Flour strength and water absorption
Different 00 flours absorb water differently.
As a result:
- 65% hydration may feel perfect with one flour
- but overly soft with another
Whenever changing flour brands, it’s important to retest hydration before adjusting other variables.
Salt and fermentation time
Salt slightly tightens gluten and slows fermentation.
If:
- salt is reduced
- fermentation is extended
the dough can feel looser even at the exact same hydration level.

Temperature changes everything
Warmer dough ferments faster and softens earlier.
A hydration percentage that feels manageable at 24°C may feel extremely sticky at 30°C.
If your dough constantly feels like it’s “melting,” lowering hydration slightly and shortening bench time can help stabilize the workflow.
Common hydration problems (and how to fix them)
Dough is too sticky to handle
Try:
- lowering hydration by 1–2%
- allowing more rest after mixing
- tightening balling technique
- reducing excess bench flour
Too much flour during stretching can burn in the oven and create bitterness.
Dough tears while stretching
This usually happens when:
- the dough is too tight
- under-rested
- under-fermented
Try:
- increasing resting time
- checking fermentation progress
- slightly increasing hydration if necessary
Crust feels dense instead of airy
Hydration may be low, but fermentation is often the bigger issue.
Check:
- fermentation timing
- shaping technique
- gas retention during stretching
Once fermentation becomes more consistent, increasing hydration slightly can also help improve openness.
How hydration affects reheating
Hydration also changes how Neapolitan pizza reheats.
Higher-hydration doughs tend to stay softer, while lower-hydration crusts crisp up faster.

FAQ
Is 70% hydration always better for Neapolitan pizza?
Not necessarily.
Higher hydration can produce a lighter crust, but it also requires better handling, stronger flour, and more temperature control. For many setups, 62–65% is more practical and consistent.
Why does my dough feel different every batch?
Hydration is affected by:
- flour absorption
- room temperature
- dough temperature
- fermentation timing
Even small environmental changes can affect how the dough behaves.
Can I fix hydration after mixing?
You can add small amounts of water during mixing, but it becomes much harder once gluten develops fully.
Usually, it’s better to adjust the next batch gradually by 1–2%.
