Pizza Rule
(telegra.ph)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
The math only really works for 18+ inch pizzas though. The pizza places around me don't even offer 18 inch pizzas. 14" large or 16" XL are the highest they go. In that case at most places near me, two twelves is often cheaper per square inch and does have more area than one 14" or 16". Especially since Domino's usually has coupons for two 12s that make it significantly cheaper than 1 L or XL.
Factor in the crust ratio of those though. We're talking 1.5 inch of crust, so 16" vs 12" is actually more like comparing 13" to 9" of pizza with cheese and topping. 132 v 64 square inches. You're getting 70 squares inches of crust on that 16", and 49 square inches of crust on the 12 inch. So more total food on 2 12s, but a lot more crust than one 16.
Even better!
Make it extra crust with pieces of crust as a topping and it'll be perfect.
Pizza place that just opened up down the street from me only offers one size:
18 inches.
The other option is to purchase by the slice.
