Electric Guitar String Height Chart 

Proper string height, also known as guitar action, is one of the biggest factors affecting how an electric guitar feels and sounds. If the strings are too high, the guitar can be difficult to play and may cause finger fatigue. If they're too low, you may experience fret buzz, dead notes, or poor sustain.

Using the correct string height helps improve comfort, playability, and tone. In this guide, you'll find a recommended electric guitar string height chart, learn how to measure your guitar's action, and discover what adjustments may be needed for the best performance.

What Is String Height?

String height is the distance between the bottom of each string and the top of the fret. This measurement is usually taken at the 12th fret using a Guitar String Action Ruler.

Having the correct string height can help:

  • Improve playing comfort
  • Reduce finger fatigue
  • Minimize fret buzz
  • Increase sustain
  • Improve note clarity
  • Maintain better intonation

Recommended Electric Guitar String Height Chart

For most electric guitars, the following measurements provide an excellent starting point.

String Recommended Height
Low E (6th String) 1.5–1.75 mm
High E (1st String) 1.25–1.5 mm

These measurements are taken at the 12th fret while the guitar is tuned to standard pitch.

Every guitarist has a different playing style, so you may choose to make small adjustments after testing the guitar.

Why String Height Matters

Proper string height affects nearly every aspect of your guitar's performance.

With the correct setup, you can enjoy:

  • Easier fretting
  • Faster playing
  • Cleaner notes
  • Better sustain
  • Reduced buzzing
  • Improved overall comfort

Even small changes in string height can make your guitar feel completely different.

Tools You'll Need

Before checking your guitar's action, gather the following tools:

Using a Guitar String Action Ruler provides the most accurate measurements and makes adjustments much easier.

How to Measure Electric Guitar String Height

Step 1: Tune the Guitar

Always tune your guitar to standard pitch before measuring the action.

Since string tension affects string height, measuring an untuned guitar can produce inaccurate results.

Step 2: Position the Guitar

Hold your guitar in its normal playing position rather than laying it flat on a table. This provides the most accurate measurement.

Step 3: Measure at the 12th Fret

Place the Guitar String Action Ruler directly on top of the 12th fret.

Measure from:

  • The top of the fret
  • To the bottom of the string

Check both the Low E and High E strings and compare them to the recommended measurements above.

Signs Your String Height Needs Adjustment

You may need to adjust your guitar if you notice:

  • Excessive fret buzz
  • Strings that feel too high
  • Notes choking during bends
  • Poor intonation
  • Uneven string height
  • Difficulty playing barre chords

Regularly checking your setup helps keep your guitar performing at its best.

Factors That Affect String Height

Bridge height isn't the only thing that affects your action.

Other important setup factors include:

  • Neck relief
  • Nut slot height
  • String gauge
  • Fret wear
  • Seasonal humidity changes

If one of these components is out of adjustment, changing the bridge height alone may not solve the problem.

Choosing the Right String Height

Every guitarist has different preferences depending on their playing style.

Lower Action

Best for:

  • Lead guitar
  • Fast solos
  • Light picking
  • Modern rock

Advantages:

  • Easier fretting
  • Faster playing
  • Less finger fatigue

Slightly Higher Action

Best for:

  • Heavy rhythm playing
  • Blues
  • Aggressive picking
  • Players who prefer maximum sustain

Advantages:

  • Fuller tone
  • Reduced fret buzz
  • Better sustain

Start with the recommended measurements, then make small adjustments until your guitar feels comfortable.

Frequently Asked Questions

What is the best string height for an electric guitar?

A good starting point is:

  • Low E: 1.5–1.75 mm
  • High E: 1.25–1.5 mm

These measurements provide an excellent balance between comfort and clean tone.

Where should I measure string height?

Measure the string height at the 12th fret, from the top of the fret to the bottom of the string.

Can low string action cause fret buzz?

Yes. If the action is too low, the strings may vibrate against the frets and create unwanted buzzing.

Do heavier strings require higher action?

Sometimes. Heavier strings can vibrate differently and may require slight adjustments depending on your playing style and guitar setup.

Final Thoughts

Setting the correct string height is one of the easiest ways to improve your electric guitar's playability, tone, and overall performance. Starting with 1.5–1.75 mm on the Low E string and 1.25–1.5 mm on the High E string provides an excellent balance for most players.

Using a Guitar String Action Ruler makes measuring quick, accurate, and repeatable, helping you achieve a professional-quality setup with confidence.
