Pizza Dough Ball Weight Calculator by Size
A 12 inch Neapolitan pizza needs about 250 g of dough. Dough weight scales with AREA, not diameter: a 12 inch circle is 113.1 square inches and Neapolitan dough runs roughly 2.2 g per square inch, so 113.1 x 2.2 = 249 g. The same 2.2 g per square inch gives 111 g for an 8 inch pizza and 442 g for a 16 inch.
Pick your pizza size and style and this returns the ball weight, plus the batch total for however many you are making. The one thing worth internalising before you use it: dough weight scales with area, not diameter. A 16 inch pizza is not 33 percent more dough than a 12 inch, it is 78 percent more, because the area of a disc grows with the square of the radius.
Dough ball weight calculator
Density is dough weight divided by pizza area. It is the same idea as American thickness factor, just in grams instead of ounces.
Take this batch total to the hydration calculator to turn it into flour, water, salt and yeast.
What is dough density, and why not just use a recipe?
Dough density is dough weight divided by pizza area. It is the number that stays constant when everything else about the pizza changes, which makes it far more useful than a recipe tied to one size. Once you know that your favourite base is 2.45 g per square inch, you can produce it at any diameter without guessing.
American pizzerias have used the same idea for decades under the name thickness factor, measured in ounces per square inch. The conversion is exact: 1 oz per square inch is 28.35 g per square inch, so a thickness factor of 0.08 is 2.27 g per square inch and a thickness factor of 0.10 is 2.84. Both figures are shown in the results so you can talk to either tradition.
The formula is short enough to do in your head at the bench:
- Round pizza area = 3.1416 multiplied by the radius squared, where radius is half the diameter
- Rectangular pan area = length multiplied by width
- Ball weight = area multiplied by density
- Batch total = ball weight multiplied by the number of pizzas, plus about 2 percent for waste
Why does scaling by diameter go so badly wrong?
Because area grows with the square of the radius, so intuition based on the diameter consistently underestimates how much dough a bigger pizza needs. This is the single most common reason a home-made large pizza tears in the middle during the stretch or comes out of the oven with a translucent, cracker-thin centre and a fat rim.
| Diameter | Area | Neapolitan 2.2 | New York 2.6 | Pan 3.4 | Area vs 12 in |
|---|---|---|---|---|---|
| 8 in | 50.3 sq in | 111 g | 131 g | 171 g | 44% |
| 10 in | 78.5 sq in | 173 g | 204 g | 267 g | 69% |
| 12 in | 113.1 sq in | 249 g | 294 g | 385 g | 100% |
| 14 in | 153.9 sq in | 339 g | 400 g | 523 g | 136% |
| 16 in | 201.1 sq in | 442 g | 523 g | 684 g | 178% |
| 18 in | 254.5 sq in | 560 g | 662 g | 865 g | 225% |
| 20 in | 314.2 sq in | 691 g | 817 g | 1,068 g | 278% |
Read the last column and the point becomes obvious. A 16 inch pizza needs 78 percent more dough than a 12 inch, not the 33 percent that the diameters suggest. A 20 inch needs almost three times as much. The full version of this table lives on the dough ball size chart if you want it on the fridge.
What density should I use for each style?
The density presets in the calculator come from the way each style is actually eaten. A Neapolitan is a personal pizza with a thin, wet centre and all its structure in the rim, so it runs light. A New York slice has to be picked up and folded without collapsing, so it carries more dough and usually 1 to 3 percent oil to keep it pliable. A pan pizza is not stretched at all, it is pressed to the edges and allowed to rise into a bread, so it runs far heavier.
| Style | g per sq in | Thickness factor | Typical size | Ball weight |
|---|---|---|---|---|
| Extra thin, cracker crust | 2.0 | 0.071 | 12 in | 226 g |
| Neapolitan | 2.2 | 0.078 | 12 in | 249 g |
| Contemporary Neapolitan | 2.45 | 0.086 | 12 in | 277 g |
| New York | 2.6 | 0.092 | 16 in | 523 g |
| New York, thick slice | 2.9 | 0.102 | 18 in | 738 g |
| Detroit, 10 x 14 pan | 3.4 | 0.120 | 140 sq in | 476 g |
| Sicilian, deep pan | 3.8 | 0.134 | 18 x 13 in | 890 g |
Treat these as starting points and then adjust to your own taste, because density is the most personal number in pizza. Bake a 12 inch at 249 g, then bake the next one at 275 g, and you will know within two pizzas which side of the range you belong on. That is a much faster route than reading opinions about it.
Does oven type change the ball weight?
Indirectly, and mostly through what your oven can physically fit. The floor of a 12 inch portable oven cannot take a 16 inch pizza, so the size decision is made for you before the dough decision is. Work out what your oven can actually cook with the oven size calculator before committing to a ball weight, because there is nothing more frustrating than a beautifully proofed 400 g ball and a stone it does not fit on.
Bake temperature has a smaller but real effect. A 900F oven finishes a pizza in 60 to 90 seconds, so a very thin base survives the bake without drying out. A 550F home oven with a steel takes six to eight minutes, and a base at 2.0 g per square inch will be a cracker by the time the cheese is right. If you are baking in a home oven, move up one density step from the style you are copying. Work the temperature side out on the bake temperature and time calculator.
How do I divide a batch into equal balls?
Weigh each one. Dividing a bulk dough by eye produces balls that differ by 30 or 40 g, which is a visible difference in a 250 g target, and it is the reason one pizza in a batch always comes out noticeably thicker than the others. Cut with a bench scraper rather than pulling by hand, because tearing the dough destroys the gluten network you spent hours developing and the ball never quite recovers its shape.
Shape each piece into a tight ball with a smooth top surface and a sealed seam underneath, then rest them in a proofing box with enough space between them that they can spread into discs without touching. Balls that fuse together have to be torn apart, and a torn ball never stretches evenly again. Two to three ball diameters of spacing is enough.
A 0.1 g scale is more precision than ball dividing needs, but it is the same tool the hydration calculator requires for weighing yeast, so most people only buy one. Once the balls are made, the proof time calculator tells you when they will be ready.
What about the rim, and does it count?
It does, and this is where density figures earn their keep. When you stretch a Neapolitan, you are deliberately pushing dough out of the centre and into the cornicione, so the same 250 g produces either a thin centre with a dramatic rim or an even base with almost no rim, depending entirely on technique. The ball weight sets how much material you have to distribute. It does not decide where it ends up.
That is why two people can make very different pizzas from identical balls, and why "how much dough for a 12 inch" has a range rather than an answer. If your rim is thin and your centre is thick, the fix is in the stretching, not in the calculator. Our guide to stretching pizza dough covers pushing the gas outward instead of flattening it, which is the part that decides the shape of the finished slice.
Frequently asked questions
How much dough do I need for a 12 inch pizza?
About 250 g for a Neapolitan style 12 inch pizza. The arithmetic is area multiplied by a dough density: a 12 inch circle is 113.1 square inches, and Neapolitan dough runs about 2.2 g per square inch, so 113.1 times 2.2 gives 249 g. A New York style 12 inch at 2.6 g per square inch would be about 294 g, because a New York base is thicker and carries more sauce and cheese.
How much dough for a 16 inch pizza?
A 16 inch circle is 201.1 square inches. At Neapolitan density that is about 442 g, and at New York density around 520 g. Sixteen inch is the size where ball weight matters most, because doubling the diameter from 8 inches quadruples the area. Scaling by diameter rather than by area is the single most common mistake, and it produces a 16 inch pizza that tears in the middle every time.
Why does dough weight scale with area and not diameter?
Because a pizza is a disc, and the area of a disc grows with the square of the radius. Going from a 10 inch to a 12 inch pizza is only a 20 percent increase in diameter but a 44 percent increase in area, so it needs 44 percent more dough to keep the same thickness. If you scale by diameter you get a base that gets thinner as the pizza gets bigger, which is exactly why large home-made pizzas tend to tear at the centre.
What is thickness factor in pizza dough?
Thickness factor is dough weight in ounces divided by the pizza area in square inches, the traditional American pizzeria measure. A thickness factor of 0.08 is a thin Neapolitan-style base, 0.10 is a classic New York slice, and 0.13 or higher is Sicilian or pan. This calculator uses grams per square inch instead, because home bakers weigh in grams, but the two are directly convertible: 1 oz per square inch equals 28.35 g per square inch.
Should a rectangular pan pizza be calculated differently?
Only the area formula changes. A round pizza is pi times the radius squared, a rectangular pan is simply length times width. A 10 by 14 inch Detroit pan is 140 square inches, and at a pan density of about 3.4 g per square inch that is 476 g of dough. Pan styles use a much higher density than round pizzas because the dough is pressed out to the pan edge and allowed to rise thick rather than stretched thin.
How much extra dough should I make to allow for waste?
Add about 2 percent to the batch total. Dough sticks to the bowl, the bench, the scraper and your hands, and on a 1,000 g batch that lost material is enough to leave your last ball 15 or 20 g light. Professional bakeries build in the same allowance. If you want four exact 250 g balls, mix for 1,020 g of total dough and accept that the leftover is the price of hitting every ball on target.
How we choose: we compare published manufacturer specifications, verified owner reviews, and long-established baker's percentage practice. We do not test gear in person. Dough figures are guidance, not a recipe guarantee: flour, water and room conditions all vary, so read your dough as well as the numbers.
Heat safety: a pizza oven at working temperature holds a 700F to 950F floor and a shell hot enough to burn on contact. Use long-handled peels and heat-rated gloves, keep children and pets clear, burn fuel outdoors only with clearance from anything combustible, and never pour water on a hot baking stone. Water flashes to steam instantly and thermal shock cracks stone.
