Many people come to this website with a simple query: how long is a pen? Here is our best take on an answer to this deceptively simple question.

“When asking how long is a pen?” we’d counter that by asking, in turn, “Which pen do you mean?” Maybe you’d then say, “A normal pen…” and the conversation would go in circles for a few more minutes, but in an effort to avoid this exact conversation, we’ll do what we can go get ahead of all possible variations on this question.
