Ever tried to draw smoke and ended up with something that looks suspiciously like a bunch of grapes or a stray cloud? It’s frustrating. You’re aiming for that wispy, ethereal movement—the kind you see trailing off a campfire or a snuffed-out candle—but the paper just gives you a heavy, clumpy mess. Honestly, the biggest mistake people make when figuring out how to draw smoke is treating it like a solid object. It isn't. Smoke is a suspension of carbon particles in air. It’s a ghost. If you draw it with hard outlines, you’ve already lost the battle.
Most beginners grab a 2B pencil and start circling. Stop. Smoke has no "edge." It has transitions. If you look at the work of master draftsmen or even modern concept artists like Loish, you'll notice they prioritize flow over form. Smoke is about physics, not just aesthetics. It’s about fluid dynamics—specifically, how heat interacts with the atmosphere.
The Science of the Swirl: Why Smoke Behaves That Way
Before you even touch your sketchbook, you need to understand what you're looking at. Smoke moves through two main phases: laminar flow and turbulent flow.
When smoke first leaves a source—let's say a cigarette or a burnt match—it starts as a straight, smooth line. This is the laminar phase. It’s predictable. It’s sleek. But as it rises, it loses heat and hits the surrounding air, which creates friction. That's when it breaks. It starts to wobble and then spirals into the turbulent phase. This is where those iconic loops and "S" curves come from. If you draw your smoke as a chaotic mess from the very bottom, it looks fake. You need that initial "stem" of stability to make the chaos up top feel earned.
Think about the air around the smoke. Smoke doesn't just exist in a vacuum; it’s being pushed and pulled by invisible currents. Even the slight movement of a person walking past or a draft from a window will shred the smoke into ribbons. Professional animators at Disney, especially back in the hand-drawn days of Fantasia, used to study "incidental motion." They knew that the "empty" space around the smoke was just as important as the soot itself.

Getting the Tools Right (Hint: Toss the Sharpener)
You don't need a $100 set of pencils to do this well. You do, however, need the right textures. If you’re using standard printer paper, you're going to struggle. It’s too smooth. You want something with a bit of "tooth," like a cold-press Bristol or a decent sketchbook page.
- Graphite vs. Charcoal: Graphite is shiny. If you use it for heavy smoke, you'll get a metallic glare that ruins the depth. Charcoal is matte and deep. It’s also incredibly messy, which is actually a benefit here.
- The Kneaded Eraser: This is your primary drawing tool. Not the pencil. In smoke drawing, you often "draw" by removing pigment rather than adding it.
- Blending Stumps (Tortillons): Use these sparingly. If you over-blend, you get mud. Sometimes a piece of tissue or even your pinky finger (though the oils in your skin can be a pain) works better for those soft, hazy gradients.
How to Draw Smoke Without Using Outlines
Seriously, put the mechanical pencil down. If I see a hard line around a cloud of smoke, I know it’s an amateur job. Smoke is a volume, not a shape.
Start by laying down a very light, even tone of graphite or charcoal over the area where the smoke will be. This is your "mid-tone." Now, take your kneaded eraser. Shape it into a fine point or a flat edge. Instead of drawing the smoke, you’re going to "lift" the highlights out of the gray background. This creates a soft, natural transition that a pencil line can never replicate.
Variation in density is key. Smoke is thicker at the source and becomes more transparent as it dissipates. You should be able to see "through" parts of the smoke to whatever is behind it. Artists like Stan Prokopenko often emphasize that the "lost and found" edge is the most powerful tool in an artist's kit. A "lost edge" is where the smoke is so thin it perfectly matches the value of the background. A "found edge" is where it’s thick enough to catch the light. Switching between these makes the viewer’s brain fill in the gaps, which feels much more "real" than a forced line.
Light and Shadow: The Secret to Volume
Smoke isn't white. It isn't gray. It’s a collection of surfaces that catch light. If your light source is coming from the top right, the top right of each "puff" or "curl" in your smoke needs to be the brightest. The opposite side should have a subtle shadow.
But wait. Here is where it gets tricky. Because smoke is translucent, it also experiences something called "subsurface scattering" (sorta). Light doesn't just hit the surface; it travels through the particles and bounces around. This means that sometimes, the "shadow" side of a smoke plume can actually look quite bright if there’s a light source behind it. This is called rim lighting, and it’s the fastest way to make your smoke look three-dimensional.
If you're drawing a dark, moody scene, try using a white charcoal pencil on toned paper (like Strathmore Tan). Instead of drawing the shadows, you draw the light hitting the smoke. It’s a total game-changer for your workflow. It forces you to think about where the light is hitting, rather than just where the "stuff" is.

Stylized Smoke vs. Realism
Not everyone wants to draw like a Renaissance master. Maybe you're into manga or American comic styles. In those cases, you will use lines. But the logic remains the same.
In Japanese woodblock prints (Ukiyo-e), smoke is often depicted as a series of interlocking, rhythmic curls. Think of the Great Wave off Kanagawa—those same fluid principles apply to smoke. The trick here is line weight. Make the lines thicker at the base of a curve and let them taper off into nothingness as the smoke dissipates. This creates a sense of "vanishing."
Even in a stylized comic, don't make every "puff" the same size. Nature hates symmetry. Make one loop huge and the next one tiny and jagged. Overlap them. If you have three loops in a row that are the same size, it’ll look like a cartoon tail, not a dynamic plume of exhaust or fire.
Common Pitfalls to Dodge
People usually rush. They want the smoke to be finished so they can get back to drawing the "cool" part of the image, like a dragon or a car. But smoke is the atmosphere. If the smoke is bad, the whole drawing feels flat.
- The "Sausage" Problem: This happens when you draw long, tubular shapes that don't vary in width. Real smoke expands as it rises.
- Over-blending: If you use a blending stump on everything, the smoke will look like a blurry smudge rather than a physical substance. Keep some "harder" edges in the thickest parts of the smoke to give it structure.
- Ignoring the Source: Always remember where the smoke is coming from. If it’s a heavy fire, the smoke should be dark, soot-heavy, and turbulent. If it’s a cigarette, it’s thin, blue-ish (if you're using color), and delicate.
Practical Steps to Master Smoke Drawing
Practice doesn't make perfect; deliberate practice does. You can't just doodle and expect to get better at fluid dynamics.
First, go find a candle. Light it. Blow it out. Watch the smoke. Better yet, film it in slow motion on your phone. Watch how the "stem" of the smoke holds steady for about two inches before it starts to loop. Notice how the loops get wider and more jagged as they go up. This is your best reference.
Try a "negative space" exercise. Take a piece of paper and cover a square entirely in charcoal. Now, using only your eraser, try to "carve" a plume of smoke out of that blackness. It’s hard. It’ll be messy. But it will teach you more about value and light than ten hours of pencil sketching.

Next, focus on "tapering." Every single wisp of smoke should start somewhere and end somewhere else—it shouldn't just stop abruptly. Use a very light touch at the end of your strokes. If you’re using digital tools like Procreate or Photoshop, use a brush with "pressure sensitivity" turned on for opacity. This allows you to fade the smoke out naturally.
Finally, look at the masters. Study the clouds in J.M.W. Turner’s paintings. He was the king of "atmospheric" drawing. His smoke and fog aren't shapes; they are moods. Even if you're drawing a sci-fi explosion, that sense of mood is what will make your work stand out on a platform like ArtStation or Instagram.
Stop thinking about how to draw "smoke" as a thing. Think about drawing the way air moves. When you can see the wind in your mind, the smoke will follow.
Next Steps for Your Practice:
- Study Fluid Dynamics: Look up "Kelvin-Helmholtz instability" on Google Images. It's the scientific name for those beautiful "wave" patterns you see in clouds and smoke. Understanding the geometry behind these waves will give your drawings a level of realism that most artists lack.
- Toned Paper Exercise: Buy a sheet of gray or tan paper. Use a black colored pencil for the shadows of the smoke and a white charcoal pencil for the highlights. This forces you to see smoke as a 3D volume with two sides, rather than just a gray blob.
- Limit Your Strokes: Try to draw a complex smoke plume using fewer than 20 pencil strokes. This helps you focus on the "gestalt" or the overall flow, preventing you from getting bogged down in tiny, unnecessary details that clutter the image.
