In reply to Chalky-Monkey:
Yes, is the short answer (no pun intended).
I used to have a similar problem as, while I'm not as short as you,
I'm still well under average height.
There are several things you could do to improve:
1. Basic campussing for contact strength and dynamic movement
2. Get on easy problems you know you can do, but miss holds out, to force yourself into long, dynamic moves
3. Work on lock-off strength to enable you to lock off poor holds with one arm and therefore provide yourself additional cm's of reach
4. Ignore specific problems at the wall and just spend a session every week bouncing between far-spaced holds, popping for finishing jugs, cutting loose on roofs etc., etc.
I found that adding dynamic climbing to my repertoire opened up higher grades and consequently loads more problems inside and out.
Good luck
