Standard Pizza Size
ISO 216 defines paper sizes. B0, A0, B1, A1, B2, A2, etc...
So how about matching pizza sizes?
- Should they match the paper sizes - ie, be of equal area to A4/A3/etc paper sizes?
- Should one key dimension of the pizza (either circumference or radius) be a nice metric round number? (radius=1m means a pizza with pi m² area!)
Current common pizza sizes
- 12" Diameter
- USA "small"
- This is 729cm²
- 16" Diameter
- USA "large"
- This is 1279cm²
Proposed "metric" sizes
By ISO216 surface area
"ideal" A and B series paper sizes would be the following: B3 is 1767.76 cm² A3 is 1250 cm² B4 is 883.88 cm² A4 is 625 cm²
A "Pizza with area of A0" - let's call that a "P-A0" would be a pizza of surface area of 1m!
- P-B0 - Area = B0 paper = sqrt(2) m² = 14,142 cm²
- Radius: 67.1cm
- P-AO - Area = A0 paper = 1m² = 10,000cm²
- Radius: 56.4cm
Let's start with a radius of 50cm (since this is a nice conceptual diameter of 1m) ...and then reduce radius by half for each size in the series?
- PO - Radius = 50cm
- Area = 7853 cm²
- P1 - Radius = 25cm
- Area = 1963 cm²
Let's start with a circumference of 1m. Remember, C=pi*2r
- P0 - Circumference = 1m
- Radius = 15.9 cm
- Area = 795 cm²
...this seems unreasonably small as a base size, yet the next metric niceness = a circumference of 10m, is 10x the size... and 100x the area (ie, about 8m²). yikes!
