String length adjustment is best done with an electronic tuner, in England they cost about £15 and the best ones have a needle display.
Basically you tune the open string say low E and then you press the string down on the 12th fret( a higher E ) - if both notes bring the needle to the middle position then the string length is correct - you repeat the procedure for all the strings and adjust if neccesary - when set up correctly all your chords should........SING
