Width
You want to put this towel over this scarecrow, but you have to measure its width first. If the towel doesn't have a greater width than the scarecrow, some of it will be showing. Which you definitely don't want.
The scarecrow creeps you out. You don't want to look at it anymore, so you're standing eerily close to it measuring its width, so you can hide it forever.

You finish measuring the width of the scarecrow and the width of the towel, and you realize you're the width of a habanero (はば) pepper short. This is fine, you grow those. This is a whole field of habaneros! So you pluck one off the nearest plant, tape it to the cloth, and cover that scarecrow right up.
Do you know the width of a habanero? It's one scarecrow minus one cloth.
