Standard Guitar Fret Count

Most acoustic and electric guitars have 20 to 22 frets. The most common count is 22 frets, which gives you nearly two full octaves of playable range above the open strings. Some guitars have 20 or 21 frets instead, and a few specialty models go higher — up to 24, 27, or even more — but 22 is what you'll find on the majority of guitars you encounter.

The fret count matters because it determines how high you can play on each string. A fret is a metal strip embedded across the neck at a specific distance from the previous one. When you press a string down against a fret, you shorten the vibrating length of the string, which raises the pitch. The higher up the neck you go, the higher the notes you can play.

Key Takeaways

  • Most guitars have 22 frets, though 20 and 21 are also common on acoustic models.
  • Each fret raises the pitch by one semitone, so fret 12 is one octave higher than the open string.
  • The fret count is fixed when the guitar is built and cannot be changed without major neck work.
  • Classical guitars typically have fewer frets (18 to 19) because the wider neck and body design limits access to higher positions.
  • Extended-range guitars designed for metal or progressive music often have 24 or more frets to reach higher notes.

Why Fret Count Varies Between Guitar Types

Different guitar styles have different fret counts because of how the body and neck are designed. Classical guitars usually stop at 18 or 19 frets because the wider neck and larger body make it harder to reach frets near the body. The neck joins the body at a higher fret position, physically blocking access to anything beyond that point.

Acoustic steel-string guitars typically have 20 or 21 frets. The narrower neck compared to a classical guitar allows the neck to join the body a bit higher, giving you access to a few more frets. Electric guitars most often have 22 frets, and some have 24. Because electric guitar bodies are thinner and the neck can extend further up the body, manufacturers can fit more frets into the same physical space.

If you play styles that demand very high notes — metal, progressive rock, or jazz fusion — you might seek out a 24-fret guitar. The extra frets give you two more semitones of range on each string without having to shift your hand position as far up the neck.

How Frets Are Numbered and Spaced

Frets are numbered starting from 1 at the headstock end and counting upward toward the body. The open string (before you press down on any fret) is considered fret 0. Fret 1 is the first metal strip, fret 2 is the second, and so on. This numbering matters when you read guitar tabs or chord diagrams — they tell you which fret to press and which string to use.

The spacing between frets follows a mathematical pattern called the equal temperament scale. Each fret is slightly closer to the previous one as you move toward the body. This is why the distance between fret 1 and fret 2 is larger than the distance between fret 20 and fret 21. The pattern ensures that each fret raises the pitch by exactly one semitone (half-step), so fret 12 is always one octave higher than the open string, regardless of which string you're on.

Fret Access and Cutaways

On acoustic guitars, the body shape limits how far up the neck you can comfortably reach. A cutaway — a notch cut into the upper bout of the body — gives you better access to the higher frets. Acoustic guitars with cutaways (called cutaway acoustics) let you reach frets 15 and higher more easily than a traditional rounded body would.

Electric guitars don't have this problem because the body is thinner and doesn't extend as far. You can reach the highest frets on a 22 or 24-fret electric guitar without the body getting in your way. This is one reason electric players often feel more comfortable playing in higher positions than acoustic players do.

What Happens Beyond the Last Fret

Once you reach the last fret on your guitar, you can still play higher notes by using harmonics — a technique where you touch the string lightly at specific points without pressing it down fully. Natural harmonics occur at fret 12, fret 7, and fret 5, and they ring at a higher pitch than the fretted note. Artificial harmonics and pinch harmonics extend this range even further, though they require more technique to execute cleanly.

Some players also use a capo — a device that clamps across all the strings at a specific fret — to shift the pitch of the entire guitar up. This doesn't give you access to frets beyond your guitar's physical limit, but it changes which notes the open strings produce, which can open up new fingering patterns and sounds.

Checking Your Guitar's Fret Count

If you're not sure how many frets your guitar has, the easiest way to find out is to count them. Start at the headstock end and count each metal strip as you move toward the body. You can also check the manufacturer's specifications — most guitar makers list the fret count on their website or in the product manual. If you've lost the manual, searching the model number online usually brings up the specs quickly.

Another way is to look at the inlays on the fretboard. Most guitars have dot inlays at frets 3, 5, 7, 9, 12, 15, 17, 19, and 21. Fret 12 usually has two dots or a different marker because it's the octave point. If you count the dots, you can estimate the total fret count, though this method is less precise than counting the actual frets.

Frequently Asked Questions

Do all guitars have the same number of frets?

No. Most have 20 to 22, but classical guitars have 18 to 19, and some electric guitars have 24 or more. The count depends on the guitar type and how the neck joins the body.

Can I add more frets to my guitar?

Not practically. Adding frets requires removing the fretboard, refitting it, and re-crowning all the frets. It's expensive, time-consuming, and usually not worth it. Buying a guitar with the fret count you need is the better choice.

What's the difference between fret 12 and the open string?

Fret 12 is exactly one octave higher than the open string. It's the midpoint of the fretboard and sounds the same note as the open string, just two octaves higher. This is why fret 12 is marked differently on most guitars.

Do I need 24 frets if I'm a beginner?

No. Most beginner songs and exercises use frets 1 through 7. A 22-fret guitar gives you plenty of range for learning. You only need 24 frets if you play styles that regularly use the highest positions, like metal or advanced jazz.

Why are classical guitars limited to 19 frets?

Classical guitar bodies are wider and the neck joins the body lower than on steel-string acoustics. The body physically blocks access to frets beyond 19. The design prioritizes tone and comfort for fingerstyle playing over high-fret access.
