Guitar Frets Explained: Features, Types and Tips

Guitar frets are the metal strips embedded across the fingerboard of a guitar that divide it into the chromatic scale. Press a string down behind one of those strips, and it shortens the vibrating length to produce a precise pitch. Without frets, accurate intonation across the neck would be nearly impossible for most players — which is why fretted instruments dominate popular music while fretless instruments demand years of ear training to play in tune.

What Guitar Frets Actually Are

Each fret is a T-shaped piece of metal wire pressed or glued into a slot cut across the fingerboard. The visible part — the crown — curves slightly upward. The tang, hidden inside the wood, holds the fret in place. The fret doesn't itself produce sound; it acts as a contact point that determines string length and therefore pitch. The space between two frets defines a semitone.

Fret numbering starts at the nut and increases toward the body. The 12th fret marks the octave — exactly halfway along the vibrating string length. Standard acoustic and electric guitars typically have between 19 and 24 frets, depending on the instrument's design and intended playing style.

Fret Materials

Nickel-silver — an alloy of nickel, copper and zinc — is the standard material for guitar frets. It is soft enough to machine easily, hard enough to withstand normal playing, and provides a warm, slightly smooth feel under the fingers. Most guitars from all price points ship with nickel-silver frets.

Stainless steel frets are harder and more durable. They last significantly longer than nickel-silver — some players report near-lifetime durability. The downside is that stainless steel is harder on tools during manufacture and fitting, which raises costs. Some players find stainless steel feels slightly slicker; others prefer it. For players who gig heavily, the long-term saving on refrets can be worthwhile.

EVO gold frets (a titanium-based alloy) offer a warm gold appearance with durability between nickel and stainless. They are less common and mainly found on boutique instruments. Genuine gold frets exist but are purely cosmetic and wear quickly.

Fret Sizes

Frets are described by width (the contact surface) and height. Common profiles are vintage/small, medium, medium-jumbo, and jumbo. Dunlop and Jescar both publish dimensional specifications for their fret wire, and guitar makers commonly specify which profile they use.

Narrow, low vintage guitar frets suit precise chord playing and feel closer to a classical instrument. Jumbo frets have a taller crown, which means your fingertip contacts fret before it contacts wood — this reduces resistance during bending and vibrato, and is preferred by many lead players. Medium-jumbo is often described as the all-rounder: enough height for comfortable bending, enough precision for clean chord work.

Fret Count and Scale Length

Guitar frets interact with scale length — the distance from nut to saddle — to determine where each pitch sits on the neck. Longer scales (like the Gibson Baritone or Fender Jazzmaster on longer settings) produce wider fret spacing; shorter scales (like the Gibson Les Paul's 24.75 inches vs Fender Stratocaster's 25.5 inches) bring frets closer together. This affects playability, string tension and tone.

Twenty-two frets is the most common count on electric guitars. Twenty-four frets allow two full octaves on each string but require a neck pickup positioned closer to the nut, which affects tone. Acoustic guitars typically offer 20 to 21 frets, with upper frets often difficult to access due to neck geometry.

Fret Wear and Maintenance

Guitar frets wear over time. Repeated string contact creates grooves or flat spots in the crown, which cause intonation problems, buzzing and uneven feel. How quickly frets wear depends on playing frequency, string material, and fret material. Nickel frets on a heavily played guitar may need attention after five to ten years; stainless frets on a similarly used instrument might last the guitar's lifetime.

A fret dress — levelling, crowning and polishing frets — can extend the life of worn frets significantly. A full refret replaces all frets. Both jobs can be done by a competent luthier. See our setup guide for details on when a fret job is needed and how to spot the signs.

Fret Buzz and Action

Fret buzz — the rattling sound when a fretted note vibrates against an adjacent fret — is one of the most common issues on guitars. It can result from low action, uneven frets, a warped neck or incorrect nut slots. Not all fret buzz is a problem: a small amount in a live setting is often inaudible through an amplifier. Excessive buzz points to a setup issue worth addressing.
