As both a sad nerd and a fan of Dominos pizza, I decided to calculate which of their four different pizza sizes represented the best value. I did this by calculating the area of the pizza (based on the diameter of each size) relative to the cost of that size.
Today I also made use of Dominos limited ‘555 deal’, which is three small pizzas for £5.55 each. That got me curious as to whether this was the best bite for my buck, and so I’ve compared them all. The results of this experiment are as follows:
|Type||Diameter (Inches)||Area (Inches Squared)||Price||Price per square Inch (pounds)|
|‘555’ 3 Pizza Deal||212.64||£16.65||0.078|
|Triple Bonanza (Buy 2 Large, 3rd Free)||429.42||£29.98||0.070|
|Buy One Get One Half Price (Small)||141.76||£16.49||0.116|
|Buy One Get One Half Price (Medium)||207.74||£19.49||0.094|
|Buy One Get One Half Price (Large)||286.28||£22.49||0.079|
|Buy One Get Second for £5 (Small)||141.76||£15.99||0.113|
|Buy One Get Second for £5 (Medium)||207.74||£17.99||0.087|
|Buy One Get Second for £5 (Large)||286.28||£19.99||0.070|
What we can see is that buying a regular ‘Small’ pizza is the worst value option. Large is the best value. As for the deals, my ‘555’ deal is not (but is almost) the best value deal. That prize goes equally to the Buy One Get Second for £5 (Large) and the Triple Bonanza deals.
Quite logically, it’s the best value to get as large a pizza as possible either by itself or as part of a deal. Just in case you were wondering!
Incidentally, I ate 1 and 2/3 of my three small pizzas, equal to around 118.15 square inches, meaning I’d eaten the equivalent of slightly more than a medium, but less than a large. Maths is fun.
