What is the standard measurement for guitar fret distance and how does it affect the playability of the instrument?

The standard measurement for guitar fret distance is typically around 2.0 to 2.5 millimeters. This distance affects the playability of the instrument by determining how easy it is to press down on the strings to produce clear notes. If the frets are too high or too low, it can make playing more difficult and affect the overall sound quality of the guitar.
