A beginner’s step-by-step to the guide Andrew Loomis method of constructing the human head
Start with a circle. The better the circle. the better your head will turn out. so make it good! Determine the browline and centerline based on the direction the head is facing. Keep in mind that the eyebrows will sit right on the browline. The ellipse separates the front plane and the side plane of the head. Wrapping centerlines around the sphere’s contour help to think in terms of form.
Now the side of the sphere becomes a flat plane described by straight contour lines rather than curved. This cross describes the tilt of the head. A helpful way of ﬁnding the hairline is by drawing an arc through the center of the side cross. Find the bottom of the nose by equaling the distance from the hairline to the browline. Equal thirds: From hairline to browline, from browline to noseline, from noseline to bottom of the chin.
Draw the arc from back of sphere around to chinline in order to find the jaw. Follow the centerline of the side plane all the way down to complete the structure of the jaw. The ear ﬁts in the lower-back quadrant Of the side plane. Indicate the contours of the brow-ridge, cheekbones, mouth, and chin. Now practice constructing this simpliﬁed head in all the angles. Be as deliberate with the proportions as you can. Before rushing into the features, anatomy, and lighting of the head, take the time to commit the structure and proportions of memory. Time invested in studying construction pays dividends!
A common mistake is to misjudge the direction and tilt of the model’s head. It’s helpful to focus on the cross of the front plane to accurately judge the direction the head is facing…
…and to focus on the cross of the side plane to judge the tilt of the head.
Use the Loomis method to practice the form and proportions of the skull. Pick up an artist’s skull model and draw lots and lots of them to build an intuitive understanding of the structure of the head.
