Light gauge of standard mandolin string vs light gauge of standard guitar string?

When describing string gauges, the term "light" is only a general guideline. The strings that one manufacturer might describe as "light", another might call "extra light" because there are no precise industry standards. The strings themselves are most accurately measured by gauge.

If you check the web, you'll find that the range of E strings on mandolin sets advertized as light gauge fall between .009 and .011 http://www.musiciansfriend.com/mandolin-strings?_r...

Light gauge acoustic guitar strings would tend to be more in the .011 - .012 range.....a little heavier. You can find thinner acoustic E strings but they would be considered "extra light". Electric guitar strings run a little lighter than acoustic, so those lights are equivalent to mandolin lights.

Remember that the string thickness is only one consideration. The scale length of the instrument plays a huge part in the overall tension of the string.

That's impossible to answer simply because there's so much variation. Even so-called "light gauge" guitar strings vary from one manufacturer to another.

Any guitar save would desire to tell you in case you're taking the guitar in. So JCR already replied the previous question. electric powered guitar strings are frequently lighter. maximum acoustics comes with 11's or 12's.
