Pizza topping portions: how much cheese on a 12 inch pizza
On a 12" (30 cm) pizza, use 70–80 g of tomato sauce and 90–100 g of mozzarella, or a mozzarella–cheddar blend. A 10" takes about 65 g of cheese, a 14" about 130 g and a 16" about 170 g. Scale every topping by the square of the diameter, not the diameter: a 16" pizza has 1.8 times the surface of a 12".
Pizza portion control chart by size
The 12" column is the reference, cross-checked against the Neapolitan pizza specification (60–80 g tomato and 80–100 g mozzarella on a Margherita) and the costing sheets professional pizzaioli share online. The other sizes are calculated from surface area and rounded to the nearest 5 g.
| Topping | 10" (25 cm) | 12" (30 cm) | 14" (36 cm) | 16" (41 cm) |
|---|---|---|---|---|
| Tomato sauce | 55 g | 75 g | 105 g | 135 g |
| Mozzarella or mozzarella–cheddar blend | 65 g | 95 g | 130 g | 170 g |
| Cheese on a four-cheese (mozzarella part) | 45 g | 70 g | 90 g | 120 g |
| Pepperoni | 40 g (12–15 slices) | 60 g (18–22 slices) | 80 g (25–30 slices) | 105 g (32–38 slices) |
| Ham | 55 g | 75 g | 105 g | 135 g |
| Doner / kebab meat | 55 g | 75 g | 105 g | 135 g |
| Chicken (cooked, diced) | 50 g | 70 g | 95 g | 120 g |
| Raw sliced mushrooms | 65 g | 95 g | 130 g | 170 g |
| Sweetcorn (drained) | 25 g | 40 g | 55 g | 70 g |
| Jalapeños | 15 g | 25 g | 35 g | 45 g |
| Red onion | 20 g | 30 g | 40 g | 50 g |
| Olive oil | 3 g | 4–5 g | 6 g | 7 g |

Treat these as starting points. Weigh ten of your own pizzas exactly as they leave the pass on a Friday night, compare with the chart and fix your spec. A 7" kids’ pizza works out at about 25 g of sauce and 35 g of cheese. Pepperoni counts depend on the stick: a 40 mm slice weighs roughly 3 g, so count slices rather than weighing them on the line.
Why you scale by the square of the diameter
Toppings cover a surface, and surface grows with the square of the diameter. A 10" pizza is 507 cm², a 12" is 730 cm², a 14" is 993 cm² and a 16" is 1,297 cm². So a 16" isn’t a third bigger than a 12", it’s 78% bigger. The rule:
new grams = reference grams × (new diameter ÷ reference diameter)²
Example: 95 g of cheese on a 12" gives 95 × (14 ÷ 12)² = 129 g on a 14". To refine it, allow for the crust: the outer 1.5 cm takes no topping, so working on (diameter − 3 cm)² gives a touch less on the 10" and a touch more on the 16".

How many pizzas from 1 kg of mozzarella?
- 1 kg of grated mozzarella: about 10 pizzas at 12", or 6 at 16". A 2.3 kg catering block covers roughly 24 twelve-inch pizzas.
- 1 kg of sauce: around 13 pizzas at 12".
- A 2.5 kg tin of pizza sauce: 30–33 pizzas at 12" once you allow for what’s left in the tin.
The easiest audit: divide a week’s cheese deliveries by the number of pizzas sold. If the answer is 120 g when your spec says 95, the gap is going on in the pizza maker’s hand.
Which cheese to use, before how much
What 20 g of extra cheese costs in a year
Take a shop selling 50 pizzas a day, 6 days a week, 45 weeks a year: 13,500 pizzas. With catering mozzarella at around £6.50 a kilo, an extra 20 g per pizza is 13p, or roughly £1,750 a year. A heavy-handed 40 g doubles that to about £3,500. The “generous hand” is often the most expensive member of staff.
On French trade forums, one owner describes getting most of his margin back by cutting cheese from 120 g to 100 g on his 31 cm pizzas, and 100 to 90 g on cheese-heavy ones, without a single customer comment. The usual target is food cost at 30% or less of the net (ex-VAT) selling price.
Turn these grams into a food cost
Having weighed every gram to win back a few pence a pizza, handing 25–30% of the order to a delivery app undoes the work. With your own website and commission-free online ordering, the savings from tight portion control stay in your till.
Keeping portions consistent on a busy line
- Scales at the station during training weeks and for every new starter: weigh, show, weigh again.
- Calibrated ladles and portion cups after that. A flat-bottomed 3 oz (90 ml) ladle gives roughly the 12" sauce portion; spiral it out from the centre.
- Pre-portioned cheese in deli pots before the Friday rush, colour-coded by size.
- Spread to within 1–2 cm of the edge. Piling toppings in the middle gives a soggy centre.
- Less is more. Overloading, especially with wet toppings like raw mushrooms, peppers or undrained sweetcorn, releases water and leaves the base pale.
- Laminate the chart and pin it above the prep fridge, and update it when the menu changes. Your menu descriptions, online and printed, must match what’s actually on the pizza: the FSA expects accurate allergen information for every dish, and a swapped cheese or a new sauce can bring in an allergen your listing doesn’t mention.

FAQ
How much cheese goes on a 12-inch pizza?
About 90–100 g of mozzarella or a mozzarella–cheddar blend for a standard pizza, around 70 g if other cheeses go on top. Many UK takeaways use more, but beyond 120 g the cheese pools oil and costs you margin.
How much tomato sauce per pizza in grams?
70–80 g on a 12" is enough; the Neapolitan specification says 60–80 g for a Margherita. Over 90 g the centre goes wet and the base stays pale.
How many pizzas do I get from 1 kg of mozzarella?
About 10 twelve-inch pizzas at 95–100 g, or 6 sixteen-inch. Compare a week’s cheese usage with pizzas sold to find your real portion.
How do I scale toppings for a bigger pizza?
Multiply by the square of the diameter ratio. Going from 12" to 16" multiplies the surface, and the toppings, by about 1.8. Scaling by diameter alone under-tops large pizzas.
Do I really need to weigh toppings?
Weigh for the first weeks and whenever staff change, then switch to calibrated ladles and pots. Twenty grams of extra cheese a pizza costs a busy shop around £1,750 a year.
