> The pizza comparison calculator compares buying several smaller pizzas with fewer large ones – total area, total price, price per square inch and how much you save – so you get the most pizza for your money.

## Inputs

- Option A diameter (in, cm)
- Option A – number of pizzas
- Option A – price per pizza
- Option B diameter (in, cm)
- Option B – number of pizzas
- Option B – price per pizza

## Results

- Option A total area
- Option B total area
- Option A total price
- Option B total price
- Option A per square inch
- Option B per square inch
- Better value
- Difference in total area (B vs A)

## Formula

```
Total area = number × π × (d ÷ 2)²
Price per in² = total price ÷ total area
Savings = (price per in² of the dearer option − cheaper) × area you need
```

## Explanation

Deals like "two medium pizzas" often give less pizza than one large. Comparing total area makes the trade-off obvious.

### How to use the Pizza Comparison Calculator

- **Option A diameter**
- **Option A – number of pizzas**
- **Option A – price per pizza**
- **Option B diameter**
- **Option B – number of pizzas**
- **Option B – price per pizza**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the diameter, number and price of each option.

### Tips

- Order by area, not by diameter: a 16" pizza has almost twice the area of a 12" one.
- Plan about 3 slices per adult for a meal, more for big appetites and teenagers.
- For homemade pizza, cold-ferment the dough for 24–72 hours for better flavour.
- Preheat the oven and the stone or steel for at least 45 minutes.

### Common mistakes to avoid

- Comparing prices per pizza instead of per square inch.
- Forgetting that a thick crust eats into the topping area of a small pizza.
- Over-topping homemade pizza, which leaves the middle soggy.

### What each result means

- **Option A total area** = [Option A – number of pizzas]×pi×([Option A diameter]÷2)^2
- **Option B total area** = [Option B – number of pizzas]×pi×([Option B diameter]÷2)^2
- **Option A total price** = [Option A – number of pizzas]×[Option A – price per pizza]
- **Option B total price** = [Option B – number of pizzas]×[Option B – price per pizza]
- **Option A per square inch** = [Option A total price]÷([Option A total area]÷6.4516)
- **Option B per square inch** = [Option B total price]÷([Option B total area]÷6.4516)
- **Difference in total area (B vs A)** = ([Option B total area]÷[Option A total area] - 1)×100

## Worked example

Inputs — Option A diameter: 12 in; Option A – number of pizzas: 2; Option A – price per pizza: $11; Option B diameter: 16 in; Option B – number of pizzas: 1; Option B – price per pizza: $19.

Results — Option A total area = 226 in²; Option B total area = 201 in²; Option A total price = $22.00; Option B total price = $19.00; Option A per square inch = $0.097; Option B per square inch = $0.094; **Better value = Option B**; Difference in total area (B vs A) = -11 %.

## FAQ

**Are two medium pizzas more than one large?**
Two 12 in pizzas (226 in²) are less than one 18 in (254 in²) but more than one 16 in (201 in²).

**How do I know which deal is better?**
Compare the price per square inch.

**Why do bigger pizzas cost less per inch?**
Dough, labour and oven time don't grow as fast as area.
