He doesn't have a face. That’s the first thing you realize when you sit down to learn how to draw the Slender Man. It sounds easy, right? You just leave the head blank. But if you mess up the proportions, he just looks like a tall guy in a cheap suit, and the horror immediately evaporates. To get it right, you have to tap into that specific brand of "Uncanny Valley" that Eric Knudsen—better known by his internet handle Victor Surge—perfected back in 2009 on the Something Awful forums.
Knudsen didn't just make a monster; he tapped into a primal fear of things that are almost human but stretched just thin enough to be wrong.
If you’re looking to sketch this guy, you aren’t just drawing a character. You’re trying to replicate a digital folk legend. Whether you're a fan of the original Creepypasta lore, the Slender: The Eight Pages game, or even the 2018 Sony film, the visual remains remarkably consistent. He is tall. He is thin. And he is profoundly unnatural.
The Anatomy of a Nightmare: Getting the Proportions Wrong on Purpose
Usually, art teachers tell you that an adult human is about seven and a half heads tall. Throw that out the window. If you want to master how to draw the Slender Man, you need to aim for ten, eleven, or even twelve heads tall.
Think about a spider. Or a stick insect.
Start with a very light "gesture sketch." Use a 2H pencil if you have one, or just barely touch the paper with a standard HB. You want a line that is almost invisible. Draw a small oval for the head, then drop a long, slightly curved line for the spine. This line should be excessively long. When you get to the limbs, make them look like they belong to someone twice his height. The elbows should sit lower than a normal person's waist. The fingers? They should reach past the knees.

In the original manipulated photos Knudsen created, Slender Man was often tucked into the background, partially obscured by trees. This is a great tip for your composition. If his limbs mimic the jagged, reaching branches of an old oak tree, the viewer’s brain gets confused. Is that a branch? Or is it a finger? That’s where the fear lives.
The Suit: Formalwear for the Void
Why a suit? Nobody really knows. It’s part of the mythos. Some say it makes him look like an authority figure, which adds a layer of psychological dread. When you're detailing the clothing, keep it sharp.
- The Jacket: It’s a standard two-button black suit. Don't make it baggy. It should look like it’s being stretched by his frame.
- The Tie: Usually red or black. A red tie pops against the monochrome palette and draws the eye toward the center of the figure.
- The Shirt: Crisp white.
Don't over-complicate the fabric folds. If you add too much detail to the suit, it becomes too "real." You want him to look a bit like a silhouette that has been given a three-dimensional shape. Focus the shadows in the armpits and under the lapels to give the figure some weight, so he doesn't just look like a paper cutout.
Facing the Faceless
The head is arguably the hardest part of how to draw the Slender Man. It seems counterintuitive. How can a blank space be hard?
The trick is the structure. Even though there are no eyes, nose, or mouth, there is still a skull underneath that "skin." You should lightly indicate a brow ridge and a jawline. This prevents the head from looking like a thumb. Use very soft, subtle shading around where the eye sockets would be. If you’re using digital tools like Procreate or Photoshop, use a soft airbrush with a low opacity. If you’re using charcoal or graphite, use a blending stump or even your finger to smudge a faint gray shadow into the "face."

It should look like skin has been vacuum-sealed over a featureless mannequin head.
Those Infamous Tentacles
Not every version of Slender Man has them, but they’re a staple of the "Slender-walking" imagery. They’re often called "tendrils" or "appendages." These shouldn't look like octopus tentacles. They aren't thick and fleshy. Instead, think of them as oily, black wisps of smoke that have suddenly become solid.
Draw them coming out of his back, specifically the shoulder blade area. Vary their thickness. Some should be thin as wire, others thick as a human arm. They should curve in unnatural, jerky angles. Look at some photos of dead vines or cracked glass for inspiration on these shapes.
Atmosphere and Shading: Making Him Part of the World
A drawing of Slender Man in a vacuum isn't scary. He needs a context.
If you look at the "Marble Hornets" web series, which really propelled the character into the mainstream, the horror came from the low-quality, grainy footage. You can mimic this in your art. If you're working traditionally, use "cross-hatching" to create a gritty, lo-fi texture in the background. If you're working digitally, add a "noise" filter or a slight motion blur to the edges of the character.

Keep the lighting high-contrast. This is often called chiaroscuro. You want deep, oppressive blacks and sharp, bright whites. If he’s standing in a forest, the shadows of the trees should bleed into his suit.
Avoid These Common Mistakes
People often make him too "buff." He isn't a superhero. He shouldn't have bulging biceps or a wide chest. He should look fragile, almost brittle. If you could snap him like a dry twig, you’re doing it right.
Another mistake is making the face too "smooth." While it's featureless, adding a bit of texture—maybe some faint, vein-like lines or a slight mottled gray—makes it look more like organic matter and less like a plastic mask.
Moving Toward Your Own Style
Art is about interpretation. While the "classic" Slender Man is the one we’ve discussed, don't be afraid to tweak him. Maybe in your version, his suit is tattered and old. Maybe his fingers have extra joints. The legend of the Slender Man grew because people kept adding their own "sightings" and "evidence" to the pile. Your drawing is just the next piece of evidence in that digital trail.
To really nail the vibe, try drawing him into an existing photo. Take a picture of a park or a hallway in your house, print it out (or import it to your tablet), and sketch him into the darkest corner. It’s a great exercise in matching lighting and perspective, and it’s honestly a bit chilling to see him "standing" in your own living room.
Next Steps for Your Artwork
Start by sketching three different silhouettes of varying heights and limb lengths. Don't worry about the suit yet; just focus on the "wrongness" of the frame. Once you find the one that feels the most unsettling, lay a fresh sheet of paper over it (or create a new layer) and begin building the suit around that frame. Experiment with the red tie versus the black tie to see which one creates the specific mood you're going for. Finally, try adding a "static" effect over the whole image by using quick, horizontal pen strokes to simulate the video interference often associated with his presence.
