First Fret Height

Post by DaveLeeNC » Sun Mar 11, 2018 12:22 am

Kind of the 'standard action' for a CG at the 12th fret is 3mm/4mm. Probably even more variables in play here, but what would typical height measurements be at the first fret?

Thanks

Seems like .6mm e and .7mm E comes to mind.

Probably correct. The StewMac website states .75mm and .6mm for nylon string (in the same place they recommend 4mm and 3.2mm.

Thanks.

Most of the measurement posts here refer to 1st fret height with third fret held down. I see their point and it has its uses - but it makes the increment very small - like 0.15 mm on the e - but a more mesureable 0.25 - 0.3 mm on the bass side.
Just measuring under the 1st fret as strung is a simple useful guide as to whether your nut could be lower ( sounds painful ! )
