Funnily enough, the bread content is the same either way (I work at subway). We pull out these frozen dough sticks that would be an excellent murder weapon, thaw them, then stretch them to fit the twelve inch pans. Sometimes they shrink a little I’m the proofer or while baking. But like, regardless of whether your sandwich is ten inches or twelve, the volume of bread is the same. 

It’s with a six inch that you’ve maybe got some variation since we kinda eyeball it. Also, if you’re rude, you’re getting ~5 and the next nice customer is getting 7🤷🏼‍♀️

But the bread is a vehicle for the toppings which you get less of if the bread shrinks
