Standard Bass Guitar Fret Count

Most bass guitars have between 20 and 24 frets, with 24 frets being the most common in modern instruments. A standard four-string bass typically comes with 24 frets, which gives you a range of about four octaves across all strings. The exact number depends on the bass model and manufacturer, but you will rarely encounter a bass with fewer than 20 frets or more than 36 frets.

The frets themselves are the metal strips embedded into the fingerboard that divide it into playable sections. Each fret represents one semitone (half step) in pitch. When you press a string down against a fret, you shorten the vibrating length of the string, which raises the pitch. The distance between frets gets slightly smaller as you move toward the body of the bass, following a mathematical pattern that ensures each fret produces the correct pitch.

Key Takeaways

  • Most modern bass guitars have 24 frets, though 20, 21, and 22-fret basses are also common and fully functional.
  • The number of frets determines your highest playable note on each string, but does not affect how the bass sounds or plays in lower registers.
  • Five-string and six-string basses typically have the same fret count as four-string models, giving them extended range in the lower frequencies.
  • Fret count matters more for lead bass playing and soloing than for standard bass lines, which rarely venture past the 12th fret.

Why Bass Guitars Have Different Fret Counts

The number of frets on a bass is partly a matter of tradition and partly a matter of playing style. Older bass designs, particularly Fender Precision and Jazz basses from the 1950s and 1960s, often came with 20 frets. This was standard for decades because most bass players did not need the higher notes—bass lines sit in the lower register, and the first 12 frets cover the range where most traditional bass work happens.

As bass playing evolved and players began using the instrument for more melodic and soloing work, manufacturers started adding frets. A 24-fret bass became the modern standard because it offers enough range for any playing style without making the neck uncomfortably long. Some boutique and high-end basses go up to 28, 30, or even 36 frets, but these are specialty instruments for players who specifically need that extended upper range.

How Fret Count Affects What You Can Play

The 12th fret on any string is one octave higher than the open string. On a standard four-string bass tuned E-A-D-G, the 12th fret of the E string gives you an E one octave up. If your bass has 24 frets, you can play two octaves above the open E string. With a 20-fret bass, you stop one octave plus four semitones higher.

For most bass lines and groove-based playing, fret count makes almost no practical difference. The majority of bass work happens in the first 7 frets, where the notes sit comfortably in the bass register and blend with the kick drum and low end of the mix. You would only notice the limitation of a 20-fret bass if you regularly play high melodic passages, solos, or jazz standards that venture into the upper register. For beginners and intermediate players, a 20-fret bass is completely sufficient.

Five-String and Six-String Bass Fret Counts

A five-string bass adds a low B string below the standard E, extending the range downward. Most five-string basses have the same number of frets as their four-string counterparts—typically 24. The extra string gives you five additional semitones below the open E, so you gain range at the bottom of the instrument rather than the top.

Six-string basses usually add both a low B and a high C string, and they also typically come with 24 frets. Some extended-range basses with five or six strings may have 26 or 28 frets to take advantage of the extra strings' potential, but 24 remains standard. The fret count on a multi-string bass works the same way as on a four-string—each fret raises the pitch by one semitone on whichever string you are playing.

Fret Size and Spacing

The physical size of the frets and the spacing between them change as you move up the neck, even though the number of frets stays the same. Frets near the headstock are farther apart because the string length is longer and the pitch intervals are larger in absolute distance. By the time you reach the 20th fret, the spacing is noticeably tighter, and your fingers have less room to move.

This spacing affects playability, especially for players with larger hands or those learning to play. Some basses with 24 frets have slightly wider spacing in the upper frets to make them more playable, while others maintain consistent spacing throughout. If you are shopping for a bass, it is worth playing one with your target fret count to see how the upper frets feel under your fingers.

Fretless Bass Guitars

Some bass players use fretless basses, which have no frets at all—just a smooth fingerboard. These instruments require more precise finger placement because you must land exactly on the pitch without the fret to guide you. Fretless basses produce a different tone, often described as warmer or more vocal, because the string vibrates against the smooth wood rather than stopping at a metal fret.

Fretless basses are less common than fretted ones and are typically chosen by experienced players or those playing specific genres like jazz or funk. They do not have a "fret count" in the traditional sense, but many fretless basses have fret markers—small dots or lines inlaid into the fingerboard—to show where the frets would be. These markers help with intonation and learning, even though there is no physical fret to stop your finger.

Choosing a Bass by Fret Count

If you are buying your first bass, do not let fret count be your primary concern. A 20-fret or 24-fret bass will work equally well for learning and playing standard bass lines. The difference only matters if you know you want to play high melodic passages or solos regularly. Most working bass players, even professionals, use 24-fret basses straightforward because they are the modern standard and offer flexibility without any downside.

What matters more than fret count is the overall feel of the bass—how it balances in your hands, how the neck width and thickness suit your grip, and how the tone resonates with you. Play several basses in different price ranges before deciding. A well-made 20-fret bass will serve you better than a poorly constructed 24-fret one, and the difference in price is usually minimal anyway.

Frequently Asked Questions

Can I play high notes on a 20-fret bass?

Yes, but not as high as a 24-fret bass. A 20-fret bass stops four semitones (one-third of an octave) lower than a 24-fret model on each string. For most bass playing, this is not a limitation. You only notice it if you regularly play melodies or solos in the upper register.

Do more frets make a bass harder to play?

Not significantly. The upper frets are closer together and require more precise finger placement, but this only affects you if you actually play up there. For the first 12 frets where most bass work happens, a 20-fret and 24-fret bass feel nearly identical.

Why do some basses have 22 frets?

A 22-fret bass is a middle ground between 20 and 24 frets, offering a bit more range than a 20-fret without the full extension of 24. Some manufacturers offer this as a standard option, and some players prefer the slightly shorter neck length it provides.

Does fret count affect the tone of a bass?

No. The tone comes from the wood, pickups, strings, and amplifier. Fret count only determines how high you can play, not how the bass sounds in the registers you actually use.

What is the highest fret count you can get on a bass?

Some specialty and extended-range basses go up to 36 frets, though these are rare and expensive. Most players never need more than 24 frets. Anything beyond that is for specific musical styles or personal preference.
