What the Loomis Method Is and Why It Works
The Loomis method is a proportional drawing system created by illustrator Andrew Loomis to help artists construct the human head accurately from any angle.
If you want a reliable way to draw faces without guessing proportions, learning how to use Loomis method can dramatically improve your portrait and figure sketching.
What makes it useful is its balance of structure and flexibility.
It gives you a repeatable framework for head construction while still allowing for individual features, perspective, and stylization.
Core Anatomy of the Loomis Method
The Loomis method starts with a simple sphere, then adds a side plane and a jaw shape to form the basic skull.
From there, the face is divided into proportional sections that place the brow, nose, mouth, and chin in consistent positions.
- Sphere: Represents the cranium or top part of the skull.
- Side plane: A cutaway section that establishes the side of the head.
- Jaw block: Connects the lower face and chin to the cranium.
- Center line: Shows the head’s orientation in space.
- Brow line: Typically marks the midpoint of the head.
This construction makes the method especially effective for heads turned in perspective.
Instead of placing features by eye, you build the head from simple forms and then map the facial landmarks onto that structure.
How to Use Loomis Method Step by Step
1. Draw the basic sphere
Begin with a clean circle or oval to represent the cranial mass.
Keep it simple and light, because this shape will act as the foundation for the rest of the head.
Next, draw a vertical center line down the front of the sphere.
This line helps indicate the direction the face is turning, and it becomes essential once you place the features.
2. Add the side plane
Cut a small wedge off one side of the sphere to create the side plane of the head.
In Loomis construction, this plane is often aligned with the ear region and helps define the skull’s width.
The side plane is important because it gives the head a three-dimensional feel.
Without it, the drawing can look flat or front-facing even when you want a three-quarter view.
3. Attach the jaw shape
Extend two lines from the side plane downward to form the jaw.
These lines should angle inward toward the chin, creating a tapered lower face.
The size and angle of the jaw will vary by subject.
A stronger jawline, a narrower chin, or a softer transition into the neck can all be adjusted at this stage.
4. Mark the brow line and face thirds
Once the head shape is established, place the brow line around the midpoint of the sphere.
From there, divide the remaining lower face into proportional sections for the nose and mouth.
- Brow to nose base: Helps position the nose structure.
- Nose base to chin: Guides mouth placement and lower-face proportions.
- Hairline area: Often sits above the brow line, depending on the individual.
These divisions are guides, not rigid rules.
Real faces vary, but the Loomis method gives you a dependable starting point that makes those variations easier to manage.
5. Place the features
After the structure is in place, map the eyes, nose, mouth, and ears onto the head.
The eyes typically sit across the brow line area, with the nose extending downward from the center of the face and the mouth located between the nose and chin.
Remember that features wrap around the head form.
The farther the face turns, the more one eye recedes and the more the far side of the features compresses in perspective.
6. Refine with planes and contours
Once the basic proportions are correct, refine the head by adding the planes of the forehead, cheekbones, nose, lips, and chin.
This is where the head begins to look less like a diagram and more like a portrait.
Use contour lines to show curvature and direction.
The Loomis method is not just about measurement; it is also about understanding how the skull turns in space.
How to Use Loomis Method for Different Head Angles
One of the biggest advantages of the Loomis method is its adaptability.
You can rotate the basic construction for front, profile, three-quarter, high-angle, and low-angle views.
Front view
In a front view, the center line runs straight down the center of the sphere and jaw.
Both sides of the face should appear symmetrical, though small asymmetries in the features are normal.
Three-quarter view
This is the most common and most useful angle to practice.
One side of the face becomes narrower, the far eye shifts back in perspective, and the side plane becomes more visible.
Profile view
For profile, the sphere still helps establish the skull, but the side plane and jaw become more prominent.
The facial features stack along the side of the head rather than spreading evenly across the front.
High and low angles
When the head tilts up or down, the ellipse of the skull changes and the center line curves with the form.
The Loomis method helps you keep the facial proportions stable while the perspective shifts.
Common Mistakes When Learning the Loomis Method
Many beginners treat the Loomis method as a formula instead of a construction process.
That often leads to heads that look rigid, overly symmetrical, or disconnected from real anatomy.
- Making the sphere too small: This can distort the skull proportions.
- Ignoring perspective: Feature placement must change when the head turns.
- Overdrawing the jaw: A heavy jaw can make the head look boxy or unnatural.
- Forcing symmetry: Human faces are rarely perfectly balanced.
- Skipping the center line: Without it, the head direction becomes unclear.
To avoid these issues, think in terms of volume first and features second.
The structure should support the portrait, not replace observation.
Practice Exercises to Improve Fast
If you want to master how to use Loomis method efficiently, repetition matters more than perfect drawings.
Short daily studies are often more effective than occasional long sessions.
- Draw 10 spheres and rotate the center line in different directions.
- Construct 5 heads from reference photos using only the Loomis framework.
- Practice heads from front, three-quarter, and profile views.
- Compare your construction to anatomy references, such as the skull and facial planes.
- Redraw the same head angle multiple times to improve consistency.
Using photo references from different genders, ages, and ethnic backgrounds will also help you understand how the underlying structure stays consistent while the surface features change.
How to Use Loomis Method for Portrait Drawing
In portrait work, the Loomis method is most helpful during the blocking stage.
It lets you establish placement before spending time on details like eyelashes, texture, or shading.
Professional illustrators, concept artists, and character designers often use this method because it saves time and reduces proportion errors.
It is especially valuable in digital painting workflows, where construction layers can be adjusted quickly before final rendering.
For realism, use the method to anchor the face, then compare your drawing against the reference for feature size, tilt, and spacing.
For stylized art, keep the same structural logic but exaggerate shapes or simplify planes.
Tools That Help With Loomis Construction
You do not need specialized equipment to learn the Loomis method, but a few tools can make practice smoother and more effective.
- Graphite pencils: Good for light construction lines.
- Brush pen or fineliner: Useful for confident final contours.
- Digital drawing software: Ideal for editable layers and quick revisions.
- Reference library: Helps you study real facial variation and perspective.
Many artists also keep a skull reference or anatomy book nearby.
Understanding the zygomatic arch, brow ridge, jaw angle, and nasal bridge can make your Loomis heads more convincing.
When to Move Beyond the Basics
Once the foundational version feels comfortable, you can go beyond the standard construction.
Study the planes of the head, muscle groups, and facial expressions to make your drawings more expressive and anatomically grounded.
At that stage, the Loomis method becomes less of a strict lesson and more of a visual language.
It helps you design heads quickly, control proportion with confidence, and adapt the structure to real people or invented characters.
