aren't those regular dashes? em dashes seem just a bit longer
N dashes. They are as wide as an n. M dashes are as wide as an m.
But what is em?
Em means the letter M. That's what it's called. Historically, M in a font was equally as wide as it was tall, so it's used to refer to the font size.
It's a width same as point size of a font: https://en.wikipedia.org/wiki/Em_(typography)
