When you make or repair the fretboard you need fret spacing calculator. In this article I have very nice calculator to locate fret position. Only put in your scale lenght and you get fret spacing table. But I have for you not only distances from the nut to frets but two more columns in table. First of all spacing between adjacent frets and special one distance from one chosen fret to other ones. This can be very helpful for understanding what the scale lenght on your guitar for example. You can calculate any guitar scale length up to any number of frets. It might not only be for guitars, as it's simply a calculator for the 12-tone equal temperament tuning.
