The reason a lot of guitarists have difficulty 'reaching' chords is that they are pressing way too hard with the left hand. Remeber, you are not pressing down the strings onto the frets like buttons. The only function of the left hand is to shorten the strings. I would suggest lightening up your touch a bit: Try this to prove my point: Press down a string onto a fret with all of your might....Play a note. Now try the same thing again, but this time just barely press down... just enough to hold the string onto the fret, keep the finger right behind the fret, not towards the middle..... play a note... It is exactly the same sound. So why play harder, you are just wasting energy. Once you get this down, even with small hands, you should be able to reach and play any chord with ease. For that chord, you don't need a stretch, but your hands are way too tense, that is why you think that they need streching. Again, try just lightening up your touch a bit. Hope that helps!
