Not sure about height. At least 16.1, though probably taller.
She was a brood mare after retiring from racing (she won twice!), so she's still got some mommy fat. But my daughter and the trainer will work that off of her pretty quickly.
She's re-learning her ground manners now (that "proud" look is actually her being high-strung and twitchy).
Soon she'll begin her jumper training.
