MEASURING SCALE LENGTH FOR BRIDGE POSITIONING

When assembling a guitar kit, achieving precise bridge positioning allows for optimal playability and sound. Central to this process is understanding and measuring the scale length—a fundamental factor that affects intonation, string tension, and overall performance.

What is Scale Length?

Scale length refers to the distance between the nut (at the headstock) and the bridge's saddle, where the strings make contact. It is measured at the high E string position as shown in the picture above. This measurement significantly impacts various aspects of your guitar's performance, such as fret spacing, string tension, and intonation. To achieve consistent playability across the fretboard, it's vital to maintain the correct scale length.

Measuring Scale Length

To measure the scale length of your guitar kit, follow these steps:

• High E String Measurement: Measure the distance between the nut and the bridge saddle for the high E (Em) string. This is the exact vibrating length of the string. If the holes for the bridge are not pre-drilled, the scale length value will help you position your bridge accurately and pre-drill at the right position as discussed in the bridge positioning article.
• 12th Fret Calculation Check: Measure the distance from the nut to the 12th fret and then multiply this distance by 2. This should yield the same value as the measurement from step 1 and should correspond to the scale length value provided on our product page or in the scale length table below.

Ensuring Bridge Precision

Accurate scale length measurement directly impacts bridge positioning. When marking the position for your bridge, use the verified scale length value to ensure precision. This positioning guarantees that the strings will have the correct tension, the frets will align appropriately, and your instrument will play in tune.
