Maybe it was 15 inches but it shrunk?

I made pizzas in college and we'd have to stretch the dough out alittle bigger than the box because it shrinks.

I really don’t think it could shrink by 2 full inches of diameter—like they said, that’s a full quarter of the area of the pizza. The horizontal shrinkage in the oven is likely only a few eighths of an inch
