So, Why The Dimension Debate?

So why can’t we agree on what to call this pan?

I contacted a few major cookware brands to determine why they chose one measurement over the other.

The answers revealed what I figured was true: anything goes!

Companies can set their standards for measuring pan sizes, confusing shoppers.

My theory is that you call the pan by the name you grew up hearing.

For some people, saying the smaller number first makes sense.

For others, length always comes first.

Either way, you’re not wrongas long as you agree that both pans are the same.
