For beginners interested in strings, the ukulele is a great choice to start. The ukulele is light, relatively small, and produces a sound similar to that of a guitar, mandolin, or banjo. On the other hand, there are many types of ukuleles, including the soprano ukulele, concert ukulele, etc. The ukulele is also used to play different musical genres.

The key element of any ukulele is the strings, and the vast majority of ukuleles use four strings. Strings of different thicknesses help create the ukulele's overall tone. Therefore, ukulele strings usually have different thicknesses. For example, on a soprano ukulele in standard "high-g" tuning, the E string is usually the thickest, and the G string is usually the thinnest.

This article will mainly discuss the ukulele, including its introduction, types of string materials, and the reason for the different thicknesses of strings.

Overview of the 4 String Ukulele

A standard ukulele has four strings. They are traditionally tuned G-C-E-A, so open strings sound like a C6 chord. Therefore, ukulele players sometimes refer to this tuning as the key of C.

On the other hand, the length of the ukulele strings varies depending on the size. Therefore, overall length and scale length are important when choosing strings. The first is the distance from the nut to the bridge, while the second is the string length that vibrates when plucked.

  • The soprano ukulele has 21 inches of string length and 13 inches of scale length.
  • The concert ukulele has 23 inches of string length and 15 inches of scale length.
  • The tenor ukulele has 26 inches of string length and 17 inches of scale length.
  • The baritone ukulele has 30 inches of string length and 19 inches of scale length.

Types of Ukulele String Materials

1. Nylon strings

Nylon strings are the most common type of modern ukulele strings. Nylon strings are comfortable to the touch and have a warm and soft tone. The downside is that the nylon string doesn't stay in tune like other string materials.

2. Fluorocarbon strings

Fluorocarbon string is similar to nylon string but has a brighter tone overall. Additionally, this type of string is also more durable than nylon string. However, fluorocarbon strings are more expensive than nylon strings.

3. Steel strings

Steel strings are not a traditional choice for ukuleles. Generally, this string type is more suitable for instruments such as guitars and basses. However, steel strings might be the first choice if you want a bright, breezy sound from the ukulele and you want strings that can accommodate different tunings.

4. Wound nylon strings

Wound nylon is a nylon alternative to wound metal strings. This type of ukulele string has a nylon core wrapped around a thin polymer wire. Wound nylon has a richer sound than standard strings and is most commonly found on baritone or tenor ukuleles.

5. Wound metal strings

The winding metal string is similar to winding nylon string but with a metal core. These strings produce a tone as bright as steel strings, which may make the ukulele sound more like a guitar.

Why Would String Thickness be Different?

There are several reasons why 4 string ukuleles have different string thicknesses:


The feel of ukulele strings varies with their gauge or thickness. For example, more tension is required to bend the string if the string is thicker. However, for guitarists, pitch bend is important in certain playing styles.


String gauges also affect timbre. For example, ukulele strings with smaller gauges tend to be more treble-heavy and generally work better in the higher register. On the other hand, strings with a larger gauge are better at producing lower tones in the bass range.


Generally speaking, different string gauges affect the frangibility of the strings themselves. If the ukulele strings are thicker, more tension is required to break. On the contrary, if the ukulele strings are thinner, they are likelier to break.
