Client: Looks great, just one thing, can we make the spaces in the paragraphs bigger please? Sorry, I’m a stickler for these things. I’m a real layout nerd.
Me: OK, when you say the spaces in the paragraphs, do you want me to increase the leading, or increase the size of the line breaks between the paragraphs?
Client: I don’t know what those terms mean, but but make the spaces between the paragraphs a little bigger, larger, wider.
Some layout nerd…
