What Does String Gauge Mean?

String gauge is the thickness or the diameter of the string. On a 6 string Guitar, all six strings are of different thicknesses. The first string is the thinnest or the lightest gauge. The 6th string is the thickest or the heaviest gauge. 
Same stands for other stringed instruments like bass guitars, cellos, etc. They have strings of varying thicknesses or gauges. First being the thinnest and gradually with each string, thickness or gauge increases.

What is Light String and Heavy String Gauge On a Guitar?

Thinner the string of the guitar, the lighter the string gauge. The thicker the string of the guitar, the heavier the string gauge. For e.g 1st string on a six-string electric guitar is the thinnest and have string gauges like .08, .09, .010. While the 6th string of an electric guitar, which is the thickest,  have string gauges like .042, .044, .46, etc.

What are the different guitar string gauges?

Three fundamental guitar string gauges are Light String Gauge, Medium String Gauge, and Heavy String Gauge. Apart from these fundamental string gauges, there are other string gauges. All these are subcategories of the three fundamental guitar string gauges. These string gauges are like super-light, light-medium, heavy top-light bottom, Drop tuning etc.

    • Light Gauge Strings: - Light gauge strings are thin in diameter. Gauges like .010-.048, .011-.050  are light gauges in acoustic guitar strings. String Gauge - 008-.038 and .009-.042 are light gauges in electric guitar.
      You Should select Light gauge strings for the following reasons: -
      • light Gauge strings are easy to play with, easy to bend.
      • Light Gauges sound brighter than medium or heavier gauges.
      • Light gauge strings exert less tension on the guitar neck and are a safe choice for old guitars.
Few reasons to avoid Light String Gauge
    • Light Gauge Strings produce less volume and sustain.
    • Light gauge strings are more prone to buzzing, especially if you are a player with a rough touch and like a low neck action.
  • Medium/Heavy Gauge Strings: - Medium or Heavy gauge strings are thick. They are heavy. They have more mass. So they exert more tension on the guitar neck and are difficult to play, as compared to light gauges. Heavier gauges generate more volume and sustain. They don't break easily and are less prone to buzzing so they are an excellent choice for those who play rough. Acoustic strings medium gauges are generally .013 -.056 and similar.
  • Light-Heavy Gauge: - Light heavy gauges are a combination of light and heavy strings. In modern-day playing, you cannot ignore aspects like string bending and neither can you ignore a good low end. This is why light heavy gauges are made. They offer you the best of both worlds. The 1st, 2nd and 3rd strings are of the light gauge while the 4th, 5th, and 6th strings are heavier gauges. This way you get easy playing and bright sounding with the first three strings while the top three strings produce a more bass prominent tone, good for riffs. Acoustic strings light-heavy gauges are .012-.054 and similar.

String Gauges On An Acoustic Guitar

 

Why String Gauge is Important?

Reason Number 1:- Strings are a physical aspect of your guitar that plays a major role in how your guitar sounds. As we have already learned, lighter gauges generate a more treble tone while heavier gauges generate a more mid and bass-rich tone. So if you are an electric guitar player and opt for a lighter string gauge set( like .09-.042) you will get a much more treble tone from your electric guitar. If you opt for a Heavier string gauge(like .012-.052) you will get a more mid rich tone. Same stands for other stringed instruments like acoustic guitar, bass guitar, ukulele, etc.
Reason Number 2:-The second major reason you should carefully choose your string gauge is that it greatly alters the way your guitar plays and feels. Lighter string gauges are easy to play and bend but they are more prone to fret buzz. A lighter gauge feels easy on your fingers. Most lead guitar players prefer a lighter gauge to get an easy feel. Also if you are a beginner and If you feel that playing the guitar is tough and it hurts your fingers, try out with a lighter string gauge. This could change your learning experience completely. 
Heavier gauges are difficult to play and bend but are stable and less prone to buzzing. Heavier gauges are preferred by rhythm and jazz players. 
Reason Number 3:-  This difference in thickness or gauge is the reason why different strings on a guitar are capable of tuning to a different note and produce different sounds. The thin strings oscillate on a higher frequency(treble) while the thick strings oscillate on a lower frequency(mids/bass). 
Reason Number 4:-  Tuning Stability. The third major reason is that string gauges are a major game player when it comes to guitar tuning and intonation stability. If your guitar easily gets out of tune. One of the many reasons could be your guitar strings stability and the string gauge you play. While lighter gauges easily get detuned, heavier gauges tend to stay more in tune.
Also, if you are in a drop or alternate tuning. You might need a heavier gauge to get more tuning stability and better intonation. 
Reason Number 5:- More Volume. If you want more output out of your acoustic, electric, bass guitars. Switch to a heavier gauge. Heavier gauges equal more volume or more output.

        Hi Nethan!
        Thanks for your comment.
        The bridge choice completely depends upon your guitar body shape and size. I suggest, you consult any local luthiers. They will be able to help and guide you better.

        Thanks for this lesson, I learned plenty!


      • Nethan Paul

        This is a detailed post and it has helped me understand the basics of guitar parts. I have just got a second hand guitar from a friend at a cheap price but the strings are not good. I have to replace them. I had no idea on gauge as well. Thank you for letting me know about it. Could you also suggest which Tune O Matic bridge (https://faberusa.com/product-category/faber-bridges/abr-59/) should I choose for my acoustic guitar because the strings are not sitting properly.
