According to The Buddha, we all are "buddha-nature." We are not separate selves apart from the rest of the world. Buddha-nature is Emptiness. In effect, this means that all individuals, whether human or not, are empty of separate substrata. Although the forms of different individuals are different, their essence is the same. If so, it follows that Buddha-nature is One in every individual. Ultimately, therefore, there is a deep identity between oneself and all other beings. Since nature is all beings, to live in harmony with nature is, ultimately, to live in harmony with oneself. .

No
No one is sure since the Buddha did not want his followers to erect any statues of him. Since he was born in Northern India / Nepal, you can assume he was about the same height as people there are now, which is somewhere near 5' 5" or so. But in the long term, why does it matter? Outside appearances indicate nothing as to the compassion and kindness that is within ones person.
