Pizza Sauce Coverage Calculator

Enter the pizza diameter and sauce density to find how much sauce you need.

How it is calculated

The tool treats the pizza as a flat circle. Area is A = π × (d ÷ 2)², with the diameter d in inches, giving square inches. Sauce by weight is oz = A × density, where density is ounces of sauce per square inch. Grams follow from g = oz × 28.35, so the ounces are weight ounces, not fluid ounces. If you leave the density empty it uses 0.018 oz per sq in. The diameter must be above zero and the density cannot be negative. The whole circle is counted, including any crust rim you plan to leave bare, so for a thick border you may reduce the diameter to the sauced area only. Results are shown to two decimals.

Worked example

A 14-inch pizza with the default density of 0.018 oz per square inch. The radius is 7 in, so the area is π × 7² = 3.1416 × 49 = 153.94 sq in. Sauce = 153.94 × 0.018 = 2.77 oz. In grams, 2.77 × 28.35 ≈ 78.55 g (the tool works from the unrounded ounces). Moving to a 16-inch pizza at the same density raises the area to 201.06 sq in and the sauce to 3.62 oz, about 31% more for two extra inches.

Common mistakes

  • Entering the radius instead of the diameter. A 14-inch pizza is d = 14; typing 7 gives a quarter of the correct area and sauce.
  • Entering centimetres. The field is inches, so a 35 cm pizza must be converted to about 13.8 in first; typing 35 would overstate the sauce more than six times.
  • Treating the ounce figure as fluid ounces or cups. The density is a weight, so weigh the sauce on a scale; a cup of sauce does not equal the same number of ounces.
  • Assuming the sauce scales with diameter. Because area grows with the square, a pizza twice as wide needs four times as much sauce, not twice.
  • Counting the bare crust edge. The tool sauces the full circle, so for a pizza with a wide rim, measure the sauced diameter instead.

About this calculator

Pizza sauce coverage scales with the pizza's area, not its diameter — since area grows with the square of the radius, a 16-inch pizza needs roughly 1.8× the sauce of a 12-inch one, not just a third more. The usual way to plan sauce is a target density, expressed in ounces of sauce per square inch of dough.

This calculator takes the pizza's diameter in inches and finds its area (π × r²), then multiplies by your sauce density to tell you exactly how much sauce to portion out, in ounces and grams. It's handy for pizzerias standardizing recipes across sizes and home cooks who want consistent sauce coverage whether they're making a personal 10-inch pizza or a large 18-inch one.

    You can calibrate the density to your own style. Weigh the sauce you normally put on one pizza, convert it to ounces, and divide by the pizza's area in square inches from the results. If you use 3 oz on a 14 inch pie, that comes to about 0.0195 oz per square inch. Enter that in the density box and scale to any size. How much sauce do you use on your usual size?
