String instruments have been around for centuries, and will likely continue to be used into the future. String instruments come in a variety of types, but all have one thing in common: strings!
String instruments can be divided into two main categories: stringed instruments and chorded instruments. Stringed instruments have strings that are played individually, while chorded instruments have strings that are played simultaneously.
The guitar is a chorded instrument that has a neck with several chords on it. These chords connect to a frame where the strings are plucked. Above the frame is a thin piece of wood called a headstock that connects to a string called a tuning peg. The tuning peg connects to the strings to change which note is being played.
Determine what frequency it plays
Now that you know what note your string plays, you can determine the length of the string. A string one meter long will play a note one octave lower than a string that is zero meters long.
To find out how long your guitar strings are, you need to know what frequency it plays. There are many free sites and apps that can help you determine the frequency of a note played on a given string.
Once you have determined the length of your guitar strings, you can go ahead and replace them! Make sure to keep track of which ones go on which strings, though- that way you do not mess up your guitar again.
Keep in mind that guitar strings age, just like people do. Sometimes they get too worn out and need to be replaced.
Share your results!
We hope you tried this experiment and shared your results! Did you find that the average length of a guitar string was similar to the 0.73 meters in the experiment? Did you find different lengths for different strings?
If you tried this experiment, we would love to see photos or videos of you doing it! You can share them on Twitter using @OddlyEnoughHQ or @IBiology, or on our Oddly Enough Odds & Ends Facebook page.
Calculate the length of the string
To calculate the length of the string, you need to know two things: how long the string is unfingered and what note it is tuned to play.
If you are tuning a guitar, you need to know how long the strings are when they are unfingered. The average length of a guitar string is 0.73 meters, or 27 inches. This is an easy measurement to take with a tape measure.
To calculate the pitch of the note, you need to know how many waves propagate down the string in a given amount of time. For example, if it takes one second for nine waves to propagate down the string, then the frequency (or pitch) of the note is nine cycles per second, or nine Hz.
You can find out how many waves propagate down the string by measuring its length and then doing some math (fun, right?).
Determine what frequency it plays
To determine what frequency the string plays, you need to know how long it is. You also need to know what note it plays with the chord you are trying to make.
A guitar string twice as long will sound a note one octave higher. A guitar string half as long will sound a note one octave lower.
To find the length of the string, measure it with a ruler. Most guitar strings are around 0.73 meters (28 inches) long. Some may be slightly shorter or longer depending on the guitar and tuning.
To find what note it plays, look up what notes make up that chord and see which one is closest to the sounding pitch of the string. For example, if the string sounds like an E above middle C (330 Hz), then it is a E thirdstring-fourth position fingering on the guitar.

We hope you enjoyed finding out how long a guitar string is and how to calculate the length of an unfingered guitar string. You now have the knowledge to tell anyone how long a guitar string is!

That’s pretty neat, but what does a guitar string have to do with math?
Everything we experience in life is based on certain properties or laws of nature. For example, the fact that everything is made up of molecules is a fundamental property of reality.
Similarly, the laws of physics (like gravity) are fundamental properties that determine how everything in the universe behaves. Even something as seemingly simple as why it’s harder to pull one hand away from something when the other hand is pulling it toward itself is due to a law of physics. It’s called “inverse pull.”
The more string that you have, the harder it is to pull it away from where it’s attached. This has to do with how much resistance there is to being pulled away. More length equals more resistance! Read more about this here.
