This "Guide to Drawing the Body" is a great reference chart from Joumana Medlej, majnouna.com. It was created for those drawing human anatomy but it is also useful information for those sculpting figures and creating dolls. See more charts at majnouna.com
Note: The actual size of the image is about 2400x3500 pixels, which Blogger isn't displaying full size. Chart is much easier to read if you download a copy.
