Loomis Head — sphere, jaw, planes, in that order

Why Loomis won

Three reasons. (1) Memorable abstraction. The "sphere with side planes flattened off" is mentally cheap to hold; you can construct it on a napkin from memory after one viewing. (2) Forgiving proportions. The jaw lands at a proportional offset from the sphere's center; small errors compound less than methods that rely on absolute measurements. (3) Generalizes to any angle. Once you can draw the sphere, rotating it is just rotating the construction lines on it.

What it does well

• Three-quarter views at eye level. The canonical case. Almost every Loomis tutorial uses this angle for a reason — it's where the method shines.
• Quick gesture sketches. You can land an accurate head construction in 60 seconds and refine from there.
• Teaching. Students grasp the sphere-plus-jaw concept in one lesson; they spend the next year refining the features.

Three known failure cases

• Extreme tilts (pitch > 45° forward or back). The standard construction sequence breaks because the brow-line ellipse foreshortens. Three adjustments fix it.
• Children and infants. The 1:1 cranium-to-face proportion is wrong; infants have ~60% cranium, ~40% face. Loomis's proportions assume an adult skull.
• Heavy facial-feature variation (large noses, square jaws, prominent cheekbones). The sphere works for the cranium, but the jaw landing point requires manual adjustment.

Alternatives — when to switch

The Reilly method (1940s, NYC) emphasizes rhythmic flowing lines instead of Loomis's geometric construction. Better for caricature, stylized illustration, and anyone whose end product values flowing line over realistic proportion.

The Asaro head (Asaro & Vilppu, modern) emphasizes faceted planes for lighting study. Better for sculptors, 3D modelers, and anyone whose goal is form rather than line.

The Bargue method (1860s) is observational — copy from a master plate, no abstraction. Better for atelier students building observational accuracy as a foundation.

The single fastest way to internalise the Loomis construction

Most artists who try Loomis once or twice get stuck because the construction feels arbitrary until the angle relationships become automatic. The fastest path past this is a 30-day daily-repetition exercise. Each day, draw twenty Loomis heads at varied angles — five front, five three-quarter (left and right), five profile, five tilted up or down. Twenty heads in fifteen minutes; pace yourself for accuracy, not speed. By day fifteen you stop thinking about the construction and start using it; by day thirty the ball-and-jaw silhouette appears almost without conscious effort. The cumulative time investment is roughly eight hours, after which the method is a permanent part of your figure-drawing vocabulary.

How Loomis fits into a multi-method portrait practice

Working portrait artists rarely use Loomis in isolation. The typical integration: start with Loomis to establish the head's orientation, tilt, and proportional landmarks (two minutes); switch to Asaro mentally for the plane analysis when you start modelling values and lighting (Asaro's eight major planes are the structure that light falls onto); use Reilly's rhythmic curves to integrate the features into a unified facial flow; check final proportional accuracy against the reference in the Bargue observational mode. Each method does part of the work the others handle poorly. The pillar comparing all four methods covers this integration in detail.

Try it

The Loomis Head tool lets you load a reference photo and adjust the sphere's axis interactively. The 5,000-word Loomis method pillar walks through all 13 construction steps with annotated diagrams.
