Read the complete guideWhy Bigger Pizzas Are Usually Better Deals
Pizza area grows with the square of the diameter. A 16-inch pizza has 78% more area than a 12-inch pizza, but rarely costs 78% more. This means the price per square inch decreases as the pizza gets larger, making the bigger size almost always the better deal.
Common Pizza Sizes and Areas
Standard pizza sizes and their approximate areas:
| Category | Value |
|---|---|
| Small (10") | 78.5 sq in |
| Medium (12") | 113.1 sq in |
| Large (14") | 153.9 sq in |
| Extra Large (16") | 201.1 sq in |
| Party (18") | 254.5 sq in |
Examples
Medium vs Large Value
A 12" medium pizza costs $12.99 and a 16" large costs $16.99.
The 12" pizza has 113.1 sq in ($0.115/sq in) while the 16" has 201.1 sq in ($0.084/sq in). The large pizza offers 27% more pizza per dollar.
Key takeaway: Even though the large pizza costs more upfront, you get significantly more food per dollar.
Getting the Best Pizza Deal
Use these strategies when ordering pizza:
- Always compare price per square inch, not just total price
- A pizza with double the diameter has 4x the area
- One large pizza is usually cheaper per square inch than two smalls
- Check deals: sometimes two mediums are offered for less than one large
- The number of slices does not affect how much pizza you get
Frequently Asked Questions about Pizza Deal Calculator
Is a larger pizza always the better deal?
Almost always, yes. Because area scales with the square of the diameter, a pizza that is slightly larger in diameter is significantly larger in area. The price increase is typically much smaller than the area increase.
Should I buy two medium pizzas or one large?
One large pizza is almost always more food than two mediums. Two 12" pizzas have a combined area of 226 sq in, while one 18" pizza has 254 sq in -- 12% more food, and usually for less money.
