Is there a way to limit line width in Gmail?

Question

I'd like my Gmail editor to enforce a maximum line width for emails I'm composing, say 70 or 80 chars. Is there a way to do this? Perhaps with a Chrome extension?

Answer 1

It doesn't look like there's any such tool out there.

Your most viable option is to use a text editor to compose your message and then paste it into a Gmail message. This might be helpful: How can I add line breaks to a text file?

Answer 2

Actually, Gmail does this automatically, but it only does it in plain-text messages. Turn off Rich Formatting in your message and it'll be wrapped to ~80 characters before it's sent.
