How Wide Should Fret Slots Be?

Fret slots should be wide enough to accommodate the width of the fret wire being used. The most common widths are .023″, .024″, .

025″, and .026″. These widths will work with all variations of fret wire on the market, from the thinnest to the thickest.

The width of the fret slot is also determined by the scale length of the instrument. The scale length is the distance from the nut to the saddle, and it determines how far apart the frets will be spaced. The most common scale lengths are 25.

5″, 24.75″, and 25″.

The rule of thumb is that the wider the fret slots, the easier it will be to install frets, but the narrower the slots, the better intonation you will achieve. If you are having trouble installing frets, or if your instrument’s intonation is not as good as it could be, consider widening the fret slots.
