Although string spacing only need a simple measurement, we often find a lot of customers overlook this when looking to purchase new bridge parts and pickups.
Different manufacturers or types of guitars use different string spacings, for example, most Gibson and PRS guitars use 50 mm and Fender uses 52 - 55 mm, measured low E to high E.
So we need to figure out the exact spacing in order to purchase the right part for upgrade on different guitars.
What is String Spacing?
String spacing is the distance between the strings of a guitar from low E to high E, usually measured at the bridge or pickups, because we know that it contracts at guitar nut. We also use terms like individual string spacing to describe the distance between neighbour strings.
How to Measure String Spacing?
String spacing is measured the entire distance from the center of low E string to the center of high E string.
You can also measure neigbour strings and times the number of space. You can do the measure on the bridge or pickup, for example, the middle of each center and magnetic pole. Some luthiers might make proportional string spacing considering the different diameters of each string, but most off-the-shelf guitars come with equal setup purely because it's simple and quick to use.
Why is it Important?
If you'd like to replace your guitar bridge, bridge saddles, or pickups, it's essential to know the string spacing before you purchase any parts. Otherwise, you might purchase the wrong ones.
