Guitar String Lifespan Calculator
Find out when to change your guitar strings based on how often you play and the string type.
Includes coated vs uncoated string comparison.
Why guitar strings go dead
Guitar strings degrade through a combination of sweat, skin oils, dirt, and oxidation. The oils and acids in perspiration corrode the metal winding on bass strings and pit the surface of plain strings, gradually deadening the tone. High humidity accelerates oxidation. The result: loss of brightness, sustain, and intonation accuracy.
Factors that affect string life
- Playing time: The single biggest factor. More hours of contact = faster wear.
- Sweat acidity: Some players’ sweat is more corrosive than others. If your strings go dull noticeably fast, this may be a factor.
- String material:
- Nickel-wound (electric): Standard, warm tone. Typical life: 3–6 weeks of regular play.
- Stainless steel (electric): Brighter, more corrosion-resistant. Life: 6–10 weeks.
- 80/20 Bronze (acoustic): Bright when new but oxidises quickly. Life: 2–4 weeks.
- Phosphor Bronze (acoustic): Warmer, longer life than 80/20. Life: 4–8 weeks.
- Coated strings (e.g. Elixir, Cleartone): Polymer coating protects windings. Life: 3–5× longer than uncoated equivalents, though initial brightness is slightly lower.
- Maintenance habits: Wiping strings down after every session extends life by 30–50%. String lubricants and cleaners also help.
Signs it is time to change
Your strings need replacing when: tone sounds dull or tubby, intonation is off even after tuning, you see visible rust or discolouration, strings feel rough or sticky, or you notice unusual tuning instability. For recording or live performance, many professionals change strings before every session regardless of age.
