Pizza Dough Calculator
Sizes the dough ball from the pan rather than from a recipe, using the thickness factor professionals work to, then breaks it into flour, water, salt, yeast and oil — and shows why going up two inches needs far more dough than it sounds like.

What this result does not account for
- Thickness factor is a loading constant, not a baked height — hydration, fermentation and rim technique all change the finished thickness.
- Style ranges overlap and vary between pizzaiolos; the factors offered are representative rather than definitive.
- Yeast is fixed at 0.3% of flour and is not adjusted for fermentation time or temperature.
- Assumes the dough is stretched to the stated size; a thick unpressed rim concentrates dough away from the centre.
- Does not model flour strength, and high hydration in a weak flour will not behave as the numbers suggest.
In short: Dough scales with area, not diameter. Going from a 12-inch to a 16-inch pizza is only 1.33× across but 1.78× the dough — 78% more, not 33%. The professional method is the thickness factor: ounces of dough per square inch, typically 0.07–0.08 Neapolitan, 0.085–0.095 New York and 0.12–0.14 for pan and Detroit styles.
Formula
dough weight (oz) = area (in²) × thickness factor
round area = πr² · rectangular area = length × width
total dough = flour × (1 + hydration + salt + yeast + oil)
∴ flour = total dough ÷ (1 + hydration + salt + yeast + oil)
[('TF', 'Thickness factor — ounces of dough per square inch. A loading constant, not a height.'), ('0.075 / 0.09 / 0.13', 'Neapolitan, New York, and Detroit or Sicilian.'), ('28.35 g', 'One avoirdupois ounce, for converting the loading into grams.'), ('1 + Σ%', 'The divisor that turns a target dough weight back into flour, since every percentage is against flour.')]
Worked Example
- Measure the pan, not the recipe. Round pizzas use πr²; rectangular pans are length times width.
- Pick a thickness factor. 0.06 cracker, 0.075 Neapolitan, 0.09 New York, 0.125 pan, 0.13 Detroit.
- Multiply for the ball weight. Area times thickness factor gives ounces; multiply by 28.35 for grams.
- Add a handling reserve. Five percent at home, more for wet dough or many pies.
- Divide back to flour. Total dough divided by one plus all the percentages gives the flour; every other ingredient follows from it.
Four 12-inch Neapolitan pizzas at a thickness factor of 0.075 need 240 g per ball, and with a 5% handling reserve that is about 1,008 g of dough in total. At 62% hydration with 2.5% salt and no oil, that resolves to roughly 609 g of flour, 378 g of water and 15 g of salt. Order 16-inch pans instead and the same four pizzas need 78% more dough — not the 33% the change in diameter suggests.
Strengths & Limits Of This Model
Where this engine is strong
- Sizes dough from the pan you actually own instead of from a recipe written for another one.
- Makes the area-versus-diameter trap explicit and quantifies it.
- Inverts baker's percentages correctly to recover flour from a target dough weight.
- Includes a handling reserve, which recipes almost never do.
Where it stops
- Thickness factor has to be chosen, and the style ranges overlap.
- Cannot account for individual stretching technique, which changes the effective area.
- Fixed yeast percentage will not suit every fermentation schedule.
Practical Use Cases
Sizing dough for a pan you already own
Working forwards from area is more reliable than hunting for a recipe written for your exact pan.
Scaling a pizza night to a guest count
Ball weight times count plus a handling reserve, then back to flour in one step.
Finding your own thickness factor
Divide a ball weight you already like, in ounces, by the area you stretch it to. That number then scales to any size.
Diagnosing a base that came out too thin
Usually the same ball stretched to a larger diameter — loading falls with the square of the size.
Methodology & Editorial Standards
Dough weight is derived from pan area rather than from a recipe, using the thickness factor convention standard in professional pizza making: ounces of dough per square inch of finished pizza. Round area is πr² and rectangular area is length times width, and the resulting ounce figure is converted at 28.349523125 g per avoirdupois ounce. The thickness factors offered — 0.06 cracker, 0.075 Neapolitan, 0.09 New York, 0.11 medium, 0.125 pan, 0.13 Detroit and Sicilian, 0.14 Chicago deep dish — sit within the published ranges for each style. Ingredient quantities are then recovered by inverting the baker's-percentage identity: total dough equals flour multiplied by one plus the sum of hydration, salt, yeast and oil percentages, so flour equals total dough divided by that sum. Yeast is held at 0.3% of flour, a modest same-day level, and is included in the divisor rather than ignored even though its effect on the total is small. The handling reserve is applied to the batch total, not to the individual ball weight, since the loss occurs at the bowl and the bench rather than per pizza. Verification against published ball weights: a 12-inch at 0.075 gives 240 g and a 10 by 14 Detroit pan at 0.13 gives 516 g, both inside the commonly cited ranges.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.

Pizza Dough Calculator — 20 Expert FAQs
20 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
How much dough do I need for a 12-inch pizza?
About 240 g for a Neapolitan at a thickness factor of 0.075, and around 290 g at 0.09 for a New York style. Published Neapolitan ball weights for a 12-inch pie cluster between 250 and 280 g, which corresponds to a thickness factor of roughly 0.078 to 0.087, so anything in that region is defensible. The style and your own preference matter more than any single published number.
What is thickness factor in pizza making?
It is the weight of dough per unit of pan area — conventionally ounces per square inch. Multiply the area of the pizza by the thickness factor and you have the dough weight, at any size. It is not a measurement of how tall the crust will be; it is a loading constant. Cracker crusts run about 0.06, Neapolitan 0.07 to 0.08, New York 0.085 to 0.095, pan pizza 0.12 to 0.13 and deep dish up to 0.15.
Why does a 16-inch pizza need so much more dough than a 14-inch?
Because dough follows area and area follows the square of the diameter. A 16-inch is only 14% wider than a 14-inch but has 31% more area, so it needs 31% more dough. Over a bigger jump the effect compounds: 12 inches to 16 inches is a third wider and 78% more dough. Scaling by diameter instead of area is the most common sizing error in home pizza making.
How do I work out flour from a target dough ball weight?
Divide by one plus all the baker's percentages expressed as decimals. For a 280 g ball at 70% hydration, 2.5% salt and 0.2% yeast, that is 280 divided by 1.727, which is 162 g of flour. Water is then 70% of that, 113 g, and so on. The reason it works is that every percentage in baker's math refers to the flour weight, so the flour is the only unknown.
What hydration should pizza dough be?
Around 60 to 65% for Neapolitan, 58 to 63% for New York, and 68 to 75% for pan and Detroit styles, which are proofed in an oiled pan and do not need to be stretched by hand. Roman al taglio runs 75 to 85%. Higher hydration gives a lighter, more open crumb but a stickier dough, and it demands a flour with enough protein to carry the water.
How much yeast for pizza dough?
Very little, especially for a long ferment. Around 0.2 to 0.3% of flour weight in instant yeast suits a same-day dough, and 0.05 to 0.1% is plenty for a 48-hour cold ferment in the refrigerator. Pizza is one of the clearest cases where less yeast and more time produces a substantially better result — the flavour comes from the fermentation, not from the yeast.
Should I add oil to pizza dough?
It depends on the style. True Neapolitan uses none at all under the VPN convention. New York style uses 1 to 3%, which contributes to the foldable texture and helps the crust brown at the lower temperatures of a domestic oven. Pan and Detroit styles use 3 to 5%, and there is oil in the pan besides. Oil is not part of hydration — it contains no water at all.
How much dough for a Detroit style pan?
A 10 by 14 inch pan is 140 square inches, and at a thickness factor of 0.13 that is 18.2 ounces, about 516 g. Published figures for Detroit pans run 500 to 650 g, so the calculation lands in the normal range. Detroit dough is proofed in the oiled pan rather than stretched, so it needs to be slack enough to relax into the corners on its own.
Can I use the same dough ball for different pizza sizes?
You can, but the pizza changes character. Stretching a ball sized for a 12-inch out to 14 inches drops the loading by 26.5%, giving a thinner, crisper and drier base. That may be exactly what you want, but it is a different pizza rather than the same one made bigger. If you want the same eating quality at a larger size, scale the dough by area.
How much extra dough should I make for waste?
Five percent is enough for a careful home batch. Wetter doughs leave more behind, so 8 to 12% is sensible above about 70% hydration, and 12 to 18% is worth it when making many pies, where it also buys you a spare ball. Running short on the last ball after fermentation is finished is not something you can fix, which is why the allowance is cheap insurance.
Is this pizza dough calculator free to use?
Yes. It is free, requires no account, and has no usage limits. ApexConverter is funded by contextual advertising, never by selling user data.
Is my data sent to a server?
No. The engine runs as Vanilla JavaScript inside your browser under our Zero-Server Client-Side Execution model. Your figures are computed locally and are never transmitted, logged, or stored.
How accurate is this calculator?
It applies the standard closed-form formula in IEEE-754 double precision, rounding only at the display layer. The engine is reconciled against an independent reference implementation before release.
Does it work on mobile?
Yes. The interface is mobile-first with numeric keypad hints and is tested down to a 320-pixel viewport with no horizontal scrolling.
Can I use it offline?
Largely, yes. Because computation is client-side, the page continues to calculate without a network connection once it has loaded.
Which currency does it use?
Amounts display in US$ accounting format, but the underlying mathematics is currency-agnostic. The result is identical in any currency, so simply read the figures in your own.
Why does a result show an em-dash?
An em-dash indicates the calculation is not defined for the inputs given — typically a division by zero or a value outside the valid domain. We show a dash rather than a misleading number.
How do I report an error?
Email apexconverter.praxiscalc@gmail.com with the tool URL, your exact inputs, the output received and the output you expected. Verified mathematical errors are patched within 72 hours.
