Pizza Size By Brand 

Some frozen pizza brands give an “Assembled Product Dimensions” measurement. This number lets the customers know the assembled dimensions of an item.

This sizing is done to make shipping cost calculations easier to calculate, as well as to generate a label for shipping purposes (source: Maropost). When it comes to pizzas, you can tell how big they are (roughly) based on the size of the box. 

Here are some popular brands of frozen pizza and their sizes according to the data we gathered at Amazon, Walmart, and Target (deduced from the size of the boxes):
