This is a simple model to provide reference for general body proportions when working with the 8 head idealized measurements. It can still be utilized for other proportions and very easily edited to suit needs and styles. This can be helpful for starting new models from scratch to arrive at generally accurate locations of features that can then be modified as needed as no human body is the same. Also useful for checking against existing models and to study differences in the human form.
It is important to note that on average people are somewhat close to this but there is a lot of variation within the human form and so this should be used as a sanity check starting point. It is a helpful learning tool along the way. I created this while doing an anatomy study that you can see here: https://www.artstation.com/artwork/3oA38D
