I'm 15 years old and approximately 5'4. I've been riding horses for over 7 years, but have never had the opportunity to own one of my own. However, I've recently acquired the necessary fundage, resources, and proper boarding location and am super stoked to finally purchase a horse of my own. =) My only dilemma is, what is the appropriate height for a horse for a girl of my age and height? I've heard that when you stand next to the horse on a level surface, your nose should just be level with the horse's back. Has anyone else heard this? Suggestions would be sweet.
