Fretboard Radius Action
A precise tool.
What is the Fretboard Radius Action & How does it work?
The fretboard radius is a crucial factor in determining the playability and tone of a guitar or bass. A larger fretboard radius results in higher string action, which can make the instrument easier to play but may affect the sustain and clarity of sound.
The string action at the 12th fret is directly influenced by the fretboard radius. It is calculated based on the distance from the strings to the fingerboard at this specific point, which affects playability and tone.
text{String Action} = frac{R^2 – (frac{L}{2})^2}{R}
R = Fretboard Radius, L = Scale Length

Frequently Asked Questions
What is fretboard radius?
Fretboard radius is the curve of the fingerboard, measured in inches. It affects how high or low the strings sit over the neck.
How does fretboard radius affect string action?
A larger fretboard radius results in higher string action, making it easier to play but potentially reducing sustain and clarity.
What is string action at the 12th fret?
String action at the 12th fret is the distance from the strings to the fingerboard at that specific point, influencing playability and tone.
How do I measure fretboard radius?
To measure fretboard radius, use a large ruler or caliper placed across the neck at the 12th fret, ensuring it is perpendicular to the strings.
What is a typical fretboard radius for electric guitars?
A common fretboard radius for electric guitars is 7.25 inches, while basses often have a radius of 9.5 to 12 inches.
How does string action affect playing comfort?
Higher string action can make it easier to play chords and move between frets but may require more finger strength and cause fatigue over time.
Can I adjust the fretboard radius on my guitar?
Yes, you can have your guitar’s neck reset or refretted with a different radius to suit your playing style and preferences.
