What’s a good string height for my guitar?”
Totally valid question, because when you’re new to guitar you really have no frame-of-reference for what a “good action” is or what it feels like.
Over time you’ll naturally develop a personal preference for what action feels right for you. Until that time, I’ll give you some actual measurements here that you can use to know whether your guitar is currently set up in the ballpark of low, medium, or high action.

P.s. The measurements are in imperial AND metric ?
