Strings are absolutely critical to your overall sound when it comes to acoustic guitars, and play just as important a role as your playing style or your guitar’s bracing pattern or tonewood. But with so many types available, choosing the best acoustic guitar strings for you doesn't always seem so easy.

Rest easy though, as our experts have been test-driving set after set of acoustic guitar strings to ensure you quickly know which ones will help your guitar sound the way you want it to. We've also looked at strings across a variety of price points, covering off budget options and more luxurious strings for your instrument, whether you're rocking a cheap acoustic guitar or a top-level strummer.

When it comes to selecting the best acoustic guitar strings for you, there are so many decisions to make on material, gauge, and price. Coated guitar strings have made huge advances in terms of tone and feel, and are an increasingly popular choice among acoustic players looking to extend the life of their strings. 

They invariably enhance higher frequencies, too, but all of this goodness comes at a price – quite literally, as coated strings are typically more expensive.

Many of the string sets featured in this acoustic guitar strings buyer’s guide are coated, but we've included some alternatives, and some more traditional string options too.

The best acoustic guitar strings: buying advice

All of the sets featured in our best acoustic guitar strings round-up come in a variety of gauges. The string gauge - the thickness or diameter of the string - has an impact on your tone and technique, and on your guitar.

Thicker strings will sound fuller, with a more rounded low end, and on balance they tend to be louder. They’re more durable, too. Fewer string breaks? That’s great. But there are drawbacks. For players who are still building strength in their fretting hands, thick gauges can make for a chastening playing experience, especially if you are a finger-picker or like to play fast runs and bend your strings. If you are a folky strummer, heavier might be a better option.

Lighter gauge strings are easier to get a handle on, to fret and bend, and they sound a lot brighter. The trade-off is that you lose some of that bottom end. For some players that is worth it. But not all.

Take a look at your guitar, too. For smaller bodied acoustic guitars, lighter gauge strings might complement the sound better, and vice-versa, with thicker strings a better fit sound-wise for larger bodied jumbo and concert models. 

Guitar strings are measured in 1/000th of an inch, and packaged in sets that are typically referred to by their thinnest string, the high E. So a “set of 12s” will have a high E string that has a 12 gauge, measuring 0.012-inches across its diameter.

Here's a generic guide to acoustic guitar string gauges:
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

Acoustic guitar strings are commonly made of bronze, phosphor bronze, brass, nickel, silk and steel.

Each material has its own timbre. Bronze sounds bright, with bell-like clarity and a wide treble-forward frequency response. As the name suggests, phosphor bronze sees phosphor added to the alloy to slow oxidation and extend string life. Phosphor bronze strings tend to sound a little darker and warmer than bronze. 

Brass strings have plenty of top-end jangle, nickel strings have warmer tone, make an excellent vintage choice, as does monel – a nickel-based alloy that many guitarists swear by for getting the best out of their tonewood.

What about nylon strings?
If you’ve got a classical guitar, you’ll need nylon strings. In a set of classical strings, the top three strings are made from clear or rectified nylon, with the bottom three typically using bronze or silverplayed copper wire wrapped around a multi-filament core. 

Classical guitar strings are referred to as having high or low tension, with high tension strings offering a heavier feel and low tension a more easy to play feel. 

The good news? Strings are not expensive
Our biggest piece of advice would be to pick up a few options and get restringing and experimenting! What feels light to one player may pose a struggle to others. But guitar strings are cheap enough that you can try a few sets without breaking the bank. The more you experiment, the sooner you find a set that gives you the tone and feel you want.
