^^That’s not specific enough. I have a few places here that calls their large 14”. In NYC, large is 16” I think there is even 18”. Some places have XL, which is the NYC size typically, but many places don’t even make their pizzas that big. The size of the slice is quite different from a 14” to a 16”, and especially 18”. My guess is it’s at least 20% more pizza in a slice from 14” to 16”, but I didn’t calculate the geometry. You need at least 16” to sell by the slice, and most people wouldn’t eat more than 2 slices “by the slice” sizes at a party I would think.
Like I said, I’m not trying to argue with the suggested amount by the pizza place, I’m just curious about how they calculated it.
My experience is off the coasts, and in the south, the larges are often 14” and they don’t even offer a 16”
