If a guitar feels “hard to play”, the action is usually the reason. Action is the height of the strings above the frets, and it has a huge effect on comfort, tone and buzz. Too high and every note is a fight. Too low and the strings rattle.
Here’s what action is, what typical settings look like and how to tell if yours is off.
What Action Means
Action is measured at the 12th fret: the distance from the top of the fret to the bottom of the string. The low E is normally set a little higher than the high E, because thicker strings vibrate in a wider arc.
Typical Settings
These are common starting points that a tech works from. The right action for you depends on your playing style, string gauge and the guitar itself.
| Guitar | Low E at 12th fret | High E at 12th fret |
|---|---|---|
| Electric | about 1.8 to 2.2 mm | about 1.4 to 1.6 mm |
| Acoustic (steel string) | about 2.3 to 2.8 mm | about 1.6 to 2.0 mm |
| Classical (nylon) | about 3.5 to 4.0 mm | about 2.5 to 3.0 mm |
| Bass | about 2.5 to 3.0 mm | about 2.0 to 2.5 mm |
Players with a light touch often like it lower. Heavy strummers and slide players usually prefer it higher.
Action Is About More Than the Bridge
Action isn’t one adjustment. It’s the result of three things working together:
- Neck relief: the slight forward curve in the neck, set with the truss rod. Too much relief raises the action in the middle of the neck; too little causes buzz.
- Nut height: if the nut slots are too high, the first few frets feel stiff and notes play sharp. If they’re too low, open strings buzz.
- Bridge or saddle height: the final fine-tuning.
Get these in the wrong order and the problem just moves around the guitar. On acoustics, lowering the action usually means reshaping the saddle, which can’t be undone. That’s why action is something we set as part of a full setup, finishing with the intonation. More in Why DIY Guitar Setups Often Go Wrong.
Signs Your Action Is Off
Too high:
- Pressing notes down takes effort, especially above the 5th fret
- Barre chords are tiring
- Notes play slightly sharp when fretted
Too low:
- Buzz on certain frets, or everywhere (see what causes fret buzz)
- Bends “choke” and die out
- Less sustain
Why Action Changes
Action isn’t fixed. It changes with:
- The seasons: in the Netherlands, dry winter air with the heating on tends to straighten the neck and lower the action, while damp summers do the opposite. More in Is Your Guitar Ready for Autumn?
- String gauge: heavier strings pull the neck forward more
- Fret wear: over time, frets wear down unevenly
Get Your Action Set for the Way You Play
In a setup we start by asking how you play, then set relief, nut, action and intonation to match. Here’s what happens during a setup. A standard setup is €75 including VAT, and most guitars are ready within 24 to 48 hours.
GuitarBuddy is based in Zandvoort and works with players in Haarlem, Aerdenhout and Amsterdam. Book your guitar setup.
