I was talking with a potential client over coffee about producing promotional materials for his event.
Me: Sounds like what you want are buttons, which are pretty cheap to produce and memorable. I could design something in three different sizes: 1 inch, 1.5 inches and 3 inches.
He looked puzzled.
Client: I have no idea how big that is.
Me: …Okay. Well, 1 inch is about the size of a quarter.
Client: That’s kind of small. Maybe I want 3 inch buttons.
Me: He decided that he wanted 3 inch buttons. How big is 3 inches?
I pointed to the top of his cup, said it was roughly that wide in diameter. He went quiet for another moment.
Client: 3 inches is kind of big. How big is 1.5 inches?
You have the tools to solve this mystery, Sherlock.
