Electric Guitar String Tension Calculator

Electric Strings and Playability

While acoustic guitars are built for volume and resonance, electric guitars are built for playability and performance. Because electric guitars rely on amplifiers, the strings can be much thinner and the tension much lower, allowing for techniques like wide vibrato and deep string bends that are physically impossible on an acoustic.

Tension vs. 'Feel'

In the electric world, tension is often discussed in terms of 'slinkiness.'

• .008 or .009 (Super Light): Very low tension. Extremely easy to bend, but can feel 'floppy' and is prone to breaking if played aggressively.
• .010 (Regular Light): The industry standard balance of tone and playability.
• .011 or .012 (Medium): High tension. Used primarily by jazz players for a thick, warm tone, or by metal players who tune their guitars significantly lower (Drop-D or C-Standard).

The Formula

The Impact of Scale Length

A Fender Stratocaster (25.5" scale) will have higher string tension than a Gibson Les Paul (24.75" scale) when using the exact same set of strings. This is why many Gibson players use .010s, while Fender players might prefer .009s to achieve a similar 'feel' under the fingers.
