All About A Fretted Instrument's Scale Length - 12fret

The math is that for a given pitch and ‘unit weight’ (this is the weight of the string in pounds per inch), string tension changes with the square of the vibrating length. The unit weight, and hence the tension, can be adjusted by changing the material used for the string or, on wound strings, changing the ratio of core to winding.
