Electric guitar string gauge simply means the thickness of the string. One measures it in thousandths of an inch. So, a 10-gauge string has a thickness of 0.010 inches.
One usually calls the sets after the lightest string in it. For instance a set of 10s means that the high E-string is 0.010 inches thick.
What Guitar String Gauge Means
The most common electric guitar string gauge for electric guitar strings is.010-.046. One commonly calls them “regular” or “10s”. They offer great balance between tension and sound. Nickel-wound strings for electric guitars form the usual standard in the industry.
Lighter gauges, like.009-.042, give clearer sound and bend more easily, so they work for beginners.
Heavier gauges need bigger tension to reach the right notes. This makes them harder to bend and vibrate. Though, they create stronger tones.
Thinner gauges play more easily and put less pressure on the guitar neck. Even so, thicekr strings give deeper sound.
Really light gauges, like 8s, make bending and vibration feel wonderful. The strings are more loose and stretchy. They need a bit of time to adjust, because the guitar resists less strongly.
Electric guitars most commonly use strings between 9 and 11 gauges. Pickups on electric guitars affect the tone, hence the natural sound of strings matters less then on acoustic.
The length of the scale also matters a lot. Fender-scale have 25.5 inches, while Gibson-scale 24.75 inches. The longer the scale, the more tension on the strings.
Tuning also matters. For Drop D-tuning, changing only the low E to 42 up to 46 gauges, one can get stronger and steady tension. Low tuning is commonly used in metal music, and thicker gauges help that.
On acoustic guitars, 11 and 12 gauges are the standard. A set of 10s exists, but the sound can sound very weak on acoustics. The D’Addario set for acoustic gauges works like this: heavy are 014-059, medium 013-056 and light 012-053.
Classical guitar strings are totally different. One describes them usually by tension instead of gauge. Unlike steel sets, where the diameter grows straight from high E to low E, on classical the diameters are not straight.
The bass strings are much thicker compared to the treble strings. Classical strings use different materials, like clear nylon, red nylon, black nylon, titanium and composites.
Hybrid sets are worth noting. A set of 10-52 gives heavier bass strings, while it keeps light trebles. This works for players that want easy bends on high strings, but more weight below.
It takes some weeks of practice to fully adjust to a new gauge. Choosing gauges yourself, one risks poor balance. Buying awhole set, one has assurance that the gauges match one with the other.
