Pizza Size Value Calculator
Updated: PizzaCodeFinder toolRuns in your browser. We don't save your inputs.
Pizza area grows with the square of the radius — a 16" pizza has about 1.8× the area of a 12". That's why a larger pizza often beats two smaller ones on price per square inch, even when it costs more up front.
How to use this tool
- Inputs:
- Diameter, price, and quantity for each pizza you want to compare.
- Output:
- Area per pizza, $/sq-in, sq-in/$, and which option is the better value.
Results
| Pizza | Area (sq-in) | Total area | Total price | $ / sq-in | sq-in / $ |
|---|---|---|---|---|---|
| Pizza A | 113.1 | 113.1 | $14.99 | $0.13 | 7.54 |
| Pizza B— best value | 201.1 | 201.1 | $19.99 | $0.10 | 10.06 |
Best value is Pizza B — about 33.3% more pizza per dollar than the next option.
How the math works
- Area= π × (diameter ÷ 2)². A 12" pizza is ≈ 113 sq-in. A 16" pizza is ≈ 201 sq-in.
- $ / sq-in is the cost of a single square inch of pizza. Lower is better.
- sq-in / $ is how much pizza you get per dollar. Higher is better. The calculator uses this to pick the best-value pizza.
- Quantitymultiplies both area and price, so you can fairly compare e.g. "two mediums" vs "one large".
The calculator ignores crust style, toppings, density, and your personal preferences — none of those are captured in dollars per square inch.
FAQ
- Why does the big pizza win so often?
- Area grows with the square of the radius. A 16" pizza has ~1.8× the area of a 12", so even at a higher sticker price it often beats two smaller ones on cost per square inch.
