A guide to tools for observational measuring
Drawing from the nude figure offers its own challenges, including our ability to depict accurate proportions of the human body. To improve your ability to draw a believable likeness to any subject, no matter who it is, you will need to improve your understanding of proportions as they appear on the subject.
In drawing, our most valuable tool for measuring is our eyes. To become better at making intuitive visual judgements, you will need to learn to draw without relying too much on other visual measuring tools. However, when the need arises there are a range of measuring tools that can help you to either see your subject afresh or to aid your objective looking; assisting you in developing a robust approach to life drawing, so that you become familiar with all parts of the body in proportion and in the right place relative to each other.
