String Gage-to-Nuts

There is actually a "string gage to nut ratio". To quote an on-line factoid: "String Gages- 1st- .011, 2nd- .013, 3rd- .018 wound, 4th- .024 w, 5th- .011 .... Suggested nut spacing is 9/32” between strings with overall width of 1 1/8” ...". It may not make sense for a guy with a tele... but I have heard before about this... apparently, it DOES depend on what nut width you have, for a given/ expected string gage. This is all in the realm of the little elves that build these things, and maintain them... I am a pilot, and the mechanics joke about "When the little dohiccus in the back goes 'boing, boing', you always come and get us to fix it"... otherwise, we tend to go unnoticed and unrecognized and un-respected. Luckily, musicians are more feeling and caring about other people on our little orb, especially those who tend to our sick intruments/ friends. We take out guitars to the luthier like some would drive their wife to a doctor. What I mean to say is... the pilot has no idea how the condenser works, apart from in theory... likewise, we as guitarists play these things... but WHO really knew there was any connection at all between the nut width and expected string gage?
