The strings on your classical or acoustic guitar have a big factor in the sound the guitar emits. Choosing the best strings for acoustic guitar can be a daunting task! If you enter any store that sells guitar strings, you will be very confused as there are so many options and you do not know where to start!
The best strings for acoustic guitar are a matter of choice and depend on what you play. However, there are some guidelines you can follow and information you can learn that will determine what is best for you. That being said, you have to try different brands and materials until you decide what works best.
In this article, I wanted to explain the exact details of guitar strings and how to choose the right one for your guitar, and the style you play.
Read on if you want to know how to choose the best strings for acoustic guitar.
Acoustic guitar strings
The acoustic guitars don’t have pickups or amplifiers to amplify the sound, so the strings will have a big factor in the sound that comes out of the guitar, as well as the factors that you choose the strings on, including the body of the acoustic guitar itself.
Of course, the big difference is in the sound. The classical guitar has nylon strings, and it plays classical and flamenco.
The acoustic guitar has steel strings and is played by rock, pop, country, and blues. In any case, the strings of any guitar in them should not be installed on the second guitar, ever!!
I mean, it is useless to install classical strings on acoustic, and vice versa, too. The structure of the neck of the classic guitar and the top of the body cannot handle the tension of the acoustic strings.
If you do this, there is a possibility that you will damage the bridge (the place where the strings are attached).

Acoustic Strings Standards
Before we mention the main characteristics and the different types of acoustic guitar strings, we will first talk about stringing standards as they apply to both types, classic and acoustic.
Guitar strings are made with different thicknesses or you can say different standards. The thicknesses are about 1 thousandth of an inch. The minimum thickness of a string is 0.010 and the thickest is 0.059. These criteria have a significant impact on the sound of the guitar and the ability to play it.
Light Tension Standards
- Easy to play
- The bending technique is much easier
- It cuts frequently
- A low sound and the note fade quickly
- Buzzing sound from the frets, especially if the action is low
- Its tension is low on the neck, so it is recommended for very old guitars
Heavy Tension Standards
- Hard to play
- You need to press it harder to make a sound, and bending will not be easy
- The sound is much louder and the notes last longer
- A lot of tension on the guitar’s neck
Acoustic guitar strings standards by numbers
Standards may differ from one brand to another depending on the manufacturer, but in general, these are the standards and thicknesses of the strings for acoustic guitars:
- “extra light”: .010 .014 .023 .030 .039 .047
- “custom light”: .011 .015 .023 .032 .042 .052
- “light”: .012 .016 .025 .032 .042 .054
- “medium”: .013 .017 .026 .035 .045 .056
- “heavy”: .014 .018 .027 .039 .049 .059
Best Strings for acoustic guitar factors
In choosing the strings, try to take into account these factors:
1) Body Style
An important rule: if the guitar body is small, use light strings, if large, use heavy strings.
2) Playing Style
If you play finger-style, it is best to choose light strings for ease of playing. If you are playing strumming, chords, and songs, it is better that you get heavy tension, although it will not be easy if you are a beginner.
What if you play both? Then you should choose medium-light. This combines the two, the bass strings are heavy tension (for the strumming), and the treble strings are light tension (for the finger-style).
3) Desired Tone
I am sure you know by now that the heavy strings have a higher sound, especially in the bass strings because of the chords and bass notes, as for light strings, the sound will be better on treble strings because of the solos and finger-style.
4) Guitar age and condition
Old guitars are in a fragile condition, and if heavy strings are attached to them, the neck of the guitar will be pulled out of place or arched, and the bridge may come out of the guitar!
If you are not sure about the condition of your guitar, or whether heavy strings are suitable for it or not, try to consult someone who repairs guitars.
the Materials
Here are the acoustic characteristics of the most common types of guitar strings:
- Bronze: Sound clear and loud and has a strong resonance, its problem is that it wears out quickly because the bronze is oxidizing.
- Phosphoric Bronze: It sounds like bronze but is warmer and the phosphorous extends its lifespan.
- Aluminium Bronze: The sound is very strong in bass and treble and is considered better than phosphorous bronze.
- Brass: Its sound is more metallic than the rest of the strings.
- Polymer-coated: its sound is not as strong and resonant as other uncoated strings, but it is more durable and anti-rust.
- Silk and Steel: Iron strings coated with a layer of silk or nylon and copper. Its tone is softer than the rest of the strings, and it is considered the favorite strings of folk and finger-style players.

Conclusion
There are many factors to determine choosing the best strings for acoustic guitar and to say that there is only one type of string that fits them all, will be like saying there is only one type of shoe!
Here are my recommendation based on the style you play. Again, you should experiment with different types of brands until you find your “sound”.
Style of Playing | Tension | Material | Brand |
---|---|---|---|
Finger-Style | LIGHT | Silk & Steel | D’Addario |
Soloing | MEDIUM | Phosphor Bronze | Elixir |
Acoustic Rock | HARD | Bronze | D’Addario XT 80/20 |
