Free Beginner's Guide to Drawing Skulls

Understanding Skull Anatomy and Basic Structure

Before you begin drawing skulls, it's worth learning about the actual bones and shapes that make up a human skull. A skull contains 22 bones in adults, though many of these are fused together. The main sections include the cranium (the rounded upper part that holds the brain), the facial bones, and the jaw. Understanding these basic components helps you draw skulls that look realistic rather than cartoonish or distorted.

The cranium makes up roughly two-thirds of the total skull volume. It's wider at the top and narrows as it moves toward the face. The eye sockets, called orbits, are positioned in the front and slightly to the sides. The nasal cavity sits between the eye sockets and is roughly triangular in shape. The teeth sit in the upper and lower jaws, with the upper teeth anchored in the maxilla bone and the lower teeth in the mandible.

The cheekbones, or zygomatic bones, extend from the side of the skull and create the width across the face. The forehead area, made from the frontal bone, curves over the top of the eye sockets. When you look at a skull from the side, you'll notice the jaw angles back underneath the cranium rather than jutting straight forward. This angle matters when drawing skulls in profile.

Many beginner artists find it helpful to study actual skull photographs or bone models before drawing. Medical websites, anatomy textbooks, and museum collections often show clear images of real skulls from multiple angles. Spending 15 to 30 minutes examining these reference images before you draw can improve your accuracy significantly. You might sketch quick thumbnail studies—small, rough drawings—of skulls from the front, side, and three-quarter views to build mental familiarity with proportions.

Takeaway: Study reference images of actual skulls from multiple angles and identify the major bone sections before attempting your first drawing.

Proportions and Measurement Guidelines

Skull proportions follow general mathematical relationships that hold true across most adult human skulls. Learning these proportions gives you a framework for drawing skulls that look balanced and believable, even when you're working from memory or imagination.

The human skull is roughly as wide as it is tall when measured from the bottom of the jaw to the top of the cranium. If you imagine drawing a square around a front-facing skull, it should fit reasonably well, though the cranium portion is wider than the jaw area. The distance between the eyes typically equals the width of one eye. This means if you draw one eye socket, you can fit another eye socket in the space next to it, and a third eye socket could fit in that same measurement. This is sometimes called the "three eyes rule."

The distance from the bottom of the eye sockets to the bottom of the nose is roughly equal to the distance from the bottom of the nose to the chin. This creates three roughly equal zones on the face: forehead to eyebrows, eyebrows to nose, and nose to chin. The top of the eye sockets sits approximately one-third of the way down from the top of the skull.

When drawing a skull in profile (side view), the eye socket sits much farther forward on the skull than many beginners expect. The jaw extends back, and there's a noticeable curve to the top of the cranium. The nose, though made of cartilage in life, is typically shown as a small triangular void in drawings. The front teeth sit directly above the bottom teeth, and the jaw angle is sharper than the soft human face suggests.

Creating a basic construction using light circles and lines helps you establish these proportions before adding detail. Draw a large circle for the cranium, then add a smaller rectangular or heart-shaped form below it for the jaw. Lightly mark where the eye sockets, nose cavity, and teeth should go using the proportional guidelines mentioned above.

Takeaway: Use the "three eyes rule" for eye socket spacing and divide the front-facing skull into three equal horizontal zones to maintain accurate proportions.

Drawing Skulls from the Front View

The front view (also called the frontal view) is often where beginners start because you can see both sides of the skull at once and compare them for symmetry. This view shows the full width of the cranium, both eye sockets, the nasal cavity, and the upper teeth clearly.

Start by lightly sketching a large circle near the top of your paper. This circle represents the upper portion of the cranium. Below and slightly overlapping this circle, sketch a smaller shape for the jaw—this can be a rounded rectangle or an inverted heart shape, depending on the skull type. The jaw portion should be noticeably narrower than the cranium.

Next, lightly draw a vertical center line down the middle of your skull shape. This line helps you keep both sides symmetrical. Draw a horizontal line across where you want the eye sockets to sit, using the one-third measurement mentioned earlier. The eye sockets are roughly oval or almond-shaped and should be positioned equidistant from the center line. Between and slightly below the eye sockets, sketch the nasal cavity as a small triangular or heart-shaped opening.

Below the nasal cavity and centered on your vertical line, sketch a horizontal line for the teeth. The upper teeth are typically shown as a series of small rectangles sitting on top of the lower teeth. The teeth don't extend all the way to the edge of the jaw—there's space on either side. You can show individual teeth with light lines, or keep it simpler by just indicating the tooth line and adding shadows.

Once your basic shapes are in place, begin refining the outlines. The cheekbones extend from the sides of the nasal cavity outward and slightly downward. The top of the cranium has a gentle curve. The jaw tapers toward the chin, and the jaw angle (where the side of the jaw meets the bottom) is a distinct corner in a skull. Add small details like the slight ridges above the eye sockets and the texture of the teeth.

Shading brings your front-view skull to life. The eye sockets are typically dark because they're deep cavities. The nasal cavity is also dark. The cheekbones catch light if your light source comes from above or to one side, so they might stay lighter. The underside of the jaw and the spaces between teeth are usually darker. Study your reference image to see where shadows naturally fall.

Takeaway: Begin with a large circle for the cranium and a smaller jaw shape below it, use a center line for symmetry, and place eye sockets and the nasal cavity using the one-third proportion guide.

Drawing Skulls in Profile and Three-Quarter Views

The profile view (looking at the skull from the side) reveals different proportions than the front view and shows the true shape of the jaw angle more clearly. Many artists find the profile view challenging at first because the eye socket appears very far forward on the skull, and the back of the cranium is larger than the front.

For a profile skull, start with a circle for the cranium, but position it so you're only seeing the side. The eye socket will sit at the very front of this circle—this surprises many beginners who expect it to be more centered. Below and slightly forward of the circle, sketch the jaw line. The jaw extends backward and downward, then angles sharply upward at the back where it meets the cranium. This jaw angle is one of the most recognizable features of a skull in profile.

The nasal cavity appears as a small triangular opening in the middle of the front of the skull. The front teeth sit above the bottom teeth at the very front of the jaw. The back of the cranium bulges noticeably—this is where the brain was housed. The forehead slopes backward rather than being vertical. When shading a profile skull, the eye socket is dark, the cheekbone area facing the light might be lighter, and the underside of the jaw is typically darker.

The three-quarter view combines elements of both the front and profile views. Position your skull at an angle so you can see three-quarter of the front face and a bit of the side. Start with a tilted circle for the cranium and an angled jaw shape. Draw the center line at an angle rather than straight down—this helps show the skull's rotation. One eye socket will appear larger or more forward than the other because of the perspective. The nasal cavity is visible, as are the teeth, but at an angle.
