If you are new at playing guitar, or you are in the beginning stages of learning to play, you might be wondering which strings are recommended for your use. The size and type of string on a guitar can affect its general tones and sounds, so you might want to try playing on several different guitars first with different brands or sizes of strings before you decide which string plays and sounds best for you.
The type of strings one should play on depends on a number of factors including: the strength of the guitarist's hands, and whether or not it is an acoustic guitar or an electric guitar. Electric guitars tend to have lighter gauge strings when you buy them brand-new with strings already on them. Acoustic guitars tend to have slightly heavier gauge strings when you buy them brand-new than electric guitars.
There can be great benefit in learning how to play an acoustic guitar or an electric guitar. A person learning guitar might build his or her hand strength better on heavier gauge strings, by learning to play an acoustic guitar, provided he or she does not have any sort of disability in the fretting hand such as arthritis, paralysis, or carpal tunnel syndrome.
Guitar strings are made in a range of gauges that are based on thousandths of an inch. For beginning guitar players, an excellent idea is to start out on a good, basic guitar such as the "Squier Dreadnought acoustic guitar by Fender". It comes with a bronze set of strings that range in size from the high E string being a .012 to the low E string being a .052. These are considered "light" strings for an acoustic guitar, but if your hands are not strong enough, or you just prefer to start out easier, then a lighter guitar string might be better when you begin playing.
There are generally no right or wrong brands or sizes of strings to use for playing on a guitar.
Good luck and happy shredding! --James Hester
