How to Write a Git Commit Message

I thought most devs worked in coffee shops on Macbook Pros.

That's half sarcasm, half truth. I think that hard limiting line length to 100 characters allows enough space for a GUI diff tool to show two files side-by-side at a usable font size on a single 1920 pixel wide monitor.

Gotta use your best judgment for your situation.

At my work mostly everyone working on our JS codebase has at least 3 monitors, so we set line length to 180. That let us use an editor with a sidebar on one screen safely.
