Among acoustic guitars, the most common scales are clustered around 25.4–25.5 inches and 24.75 inches. ... The basic rule of scale length is simple: For any given tuning and set of strings, longer scales have higher tension.
What determines a guitars scale length?
'Scale length' refers to the distance between a guitar's nut and its bridge. So in other words, a guitar's scale length is determined by the gap between the two main components that seat its strings. It can therefore be thought of as the measurement of the maximum sounding length of a guitar's strings.
What's the difference in guitar scale length?
When people talk about a short scale, it's typically 24 3/4 inches, while long scale is over 25 inches. A greater scale length means more tension in the strings, since they have to span a greater distance. Since short-scale guitars have less string tension, they have a little more wiggle room and punch.
