I can’t say if I have small fingers or not. But the length of my fingers never has been a problem for me. Well, long fingers can definitely give you an advantage, as reaching frets can be much easier.
However, it does not mean that people with short fingers cannot be good guitarists. I mean, there are many famous guitarists who have small fingers, such as the rock legend Angus young! But I have seen some so-called “guitar teachers” claiming that people with short fingers cannot compete with guitarists with long fingers. I don’t believe that even a bit. Still, I want to know your opinion on this and understand what the majority of people think about this.
