its all in the thumb. try this:
put your thumb at the top side of the neck of the guitar (so if you had just your thumb on the neck, it would hang on to the neck) and put your middle finger on the 12th fret. now try to get your ring finger on the 15th fret.
pretty hard, isnt it?
now, put the thumb on the lower back of the neck and put your middle finger on the 12th fret.
this time if you stretch, it can easily reach the 15th fret, and with a little effort, reach the 16th fret.
ok now try this:
put your thumb the lowest it can go, touching the bottom edge of the neck. now put your middle finger on the 12th fret, and you can reach the 16th fret easily.
the reason it gets easier is because the lower your thumb is, the lower your wrist is, and the easier it is to stretch.
try this now: sorta lift your guitar so the body touches your chin. now put your middle finger on the 12th fret and stretch your ring finger. amazing! you can reach the 17th fret! wow!
hope that helped.
