The 12 Principles of Animation Explained (With Figure Drawing Insights)
We still remember the first time someone sat us down in a Montreal animation studio and walked us through the 12 principles frame by frame. A senior animator pulled up a bouncing ball test, then a walk cycle, then a clip from a classic Disney short, and suddenly the drawings we’d been doing in life class made a different kind of sense. Those principles weren’t rules invented to slow us down — they were the vocabulary behind every believable movement we’d ever watched. Today, they guide every gesture drawing we teach, whether a student is preparing an animation portfolio or simply learning to see the human figure more clearly.
Why the 12 Principles Still Matter in Modern Animation
The principles were codified by Ollie Johnston and Frank Thomas, two of Disney’s Nine Old Men, in their 1981 book The Illusion of Life. They distilled decades of studio experience into a shared language that animators could use to make drawings feel alive. That language hasn’t aged. Whether you’re keyframing a character in Maya, rigging a 2D puppet in Toon Boom, or flipping paper on a light table, the same questions come up: does this pose read, does this timing feel right, does this movement have weight?
From Disney’s Golden Age to Today’s Montreal Studios
Montreal has become one of the most active animation hubs in North America, with studios large and small producing feature films, series, and commercial work. The tools have changed dramatically since the 1930s, but the notes that supervisors give in dailies sound remarkably similar to what Johnston and Thomas wrote down. “Push the anticipation.” “Your arcs are breaking.” “Add some overlap on the cape.” Our Montreal art classes integrate these principles from day one, because students who understand them early build stronger habits and waste less time unlearning bad ones later.
How Figure Drawing Anchors Every Principle
You can memorize the 12 principles in an afternoon. Applying them takes years, and it starts with the body. Figure drawing teaches you how weight shifts through a hip, how a spine curves under load, how a hand leads an arm in a throw. Gesture drawing compresses that knowledge into seconds, training you to capture the essence of a pose before details get in the way. Every principle on this list — squash, anticipation, arcs, appeal — lives inside the human form long before it lives inside a rig.
The Core Principles: Squash, Stretch, and Anticipation
These three principles do most of the heavy lifting in any action scene. They’re also the easiest to spot when they’re missing, which is why we drill them constantly in our studio sessions.
Squash and Stretch: The Illusion of Weight and Flexibility
Squash and stretch gives objects the feeling of mass and elasticity. A rubber ball flattens on impact and elongates as it launches. A character’s face squashes on a heavy landing and stretches during a leap. Classic cartoons pushed this to extremes — think of Tex Avery’s wolves or the Genie in Aladdin. Modern 3D animation uses the same idea more subtly, often baked into rigs as volume-preserving deformers.
The rule of thumb: keep volume consistent. If a ball squashes wide, it should also get shorter. If a character stretches tall, they should narrow. Break that rule intentionally and you get a stylized effect; break it accidentally and the character looks like melting clay.
Anticipation: Setting Up the Action
Anticipation is the wind-up before the pitch. A character crouches before jumping, pulls back before throwing, inhales before speaking. Without it, actions feel sudden and weightless. In our Montreal studio, we teach anticipation through gesture drawing exercises: students hold a pose at the peak of a wind-up for 30 seconds, then flip to a 10-second gesture of the follow-through. Repeating this drill builds an instinct for where the energy comes from before it releases.
Staging, Straight Ahead, and Pose to Pose
Once you can make a single action read, the next challenge is composing it clearly and choosing a workflow that fits the shot.
Staging: Directing the Viewer’s Eye
Staging is cinematography for animators. It’s the choice of camera angle, silhouette, and composition that tells the audience where to look. A well-staged pose reads instantly, even in silhouette. A poorly staged one buries the action behind clutter. We encourage students to squint at their drawings — if the story still reads when everything goes blurry, the staging is working.
Straight Ahead vs. Pose to Pose: When to Use Each
These are the two fundamental approaches to animating a sequence:
- Straight ahead: You draw frame by frame from start to finish, discovering the action as you go. It’s spontaneous and great for effects, fire, water, and chaotic motion.
- Pose to pose: You plan key poses first, then fill in the in-betweens. It gives you control over timing and is essential for dialogue, acting, and anything that needs to hit specific beats.
Our animation training in Montreal uses both methods, often on the same portfolio project. A student might pose-to-pose a character’s walk cycle, then switch to straight ahead for the cloth simulation on their coat. Knowing when to switch is a professional skill in itself.
Follow Through, Overlapping Action, and Slow In Slow Out
These principles are about momentum — how energy continues after the main action stops, and how it accelerates and decelerates along the way.
Follow Through and Overlapping Action: Natural Momentum
Follow through is what happens after a character stops: a ponytail keeps swinging, a cape settles, a belly jiggles. Overlapping action is the related idea that different parts of the body move on different timings — the hips lead, the chest follows, the head arrives last. Hair and cloth are the classic teaching tools because their motion is entirely dependent on the body driving them. Animate the body first, then layer the secondary motion on top.
Slow In and Slow Out: Timing for Realism
Nothing in nature moves at a constant speed. A bouncing ball slows as it reaches the top of its arc and accelerates as it falls. That’s slow in and slow out, and it’s the first exercise in almost every Montreal art class we run. Students draw a ball bouncing across the page, spacing the frames closer together at the peaks and further apart near the ground. Get the spacing right and the ball feels heavy. Get it wrong and it looks like it’s floating.
Arcs, Secondary Action, and Timing
These three principles tie movement to storytelling. They’re also where a lot of student work starts to feel professional.
Arcs: The Path of Natural Movement
Almost nothing in the body moves in a straight line. A hand reaching for a cup travels along an arc. A head turning follows a curve. In figure drawing, we look for these arcs in the gesture itself — the sweep from shoulder to fingertip, the curve of the spine. In animation, we track them as motion trails and correct any pose that breaks them.
Secondary Action: Adding Depth Without Distraction
Secondary action supports the main action without stealing focus. A character scratching their chin while thinking, or adjusting a sleeve while talking, adds life. The key word is support. If the secondary action pulls attention away from the primary one, it’s no longer secondary — it’s competition.
Timing: The Difference Between Amateur and Pro
Timing is the soul of animation. The same drawings played at different speeds communicate completely different emotions. A head turn over four frames reads as a snap; over sixteen frames it reads as a slow, suspicious glance. We often point students toward the Montreal animation festival circuit, where they can watch short films back to back and feel how dramatically timing choices shape tone. Seeing a hundred different approaches in one evening teaches more than any lecture.
Exaggeration, Solid Drawing, and Appeal
The final three principles are what separate technically correct animation from animation people remember.
Exaggeration: Pushing Poses for Impact
Exaggeration means pushing a pose beyond reality to communicate its intent. A surprised character’s eyes go wider than anatomically possible. A heavy character’s steps land harder. The trick is to exaggerate the idea, not just the shapes — a scared pose should feel scared first, stretched second.
Solid Drawing: The Foundation of Figure Drawing
Solid drawing is the ability to draw a form that feels three-dimensional from any angle. It’s why we spend so much time on construction in our classes: boxes, cylinders, spheres, and how they combine into a human body. An animator who can’t draw a convincing torso from a three-quarter back view will struggle with every turn in a shot.
Appeal: Creating Characters Audiences Love
Appeal is charisma. It’s not about being cute or pretty — it’s about being interesting to look at. A villain can have appeal. A rock can have appeal. It comes from clear shapes, strong silhouettes, and poses that express personality. Our Montreal animation portfolio prep emphasizes these final principles because reviewers can spot appeal — or its absence — in a single page of sketches.
FAQ
Do I need to know all 12 principles before starting Montreal art classes?
No. We introduce them progressively, and most students arrive with little or no formal background. What matters more is a willingness to draw consistently and take feedback.
How much figure drawing do I need for an animation portfolio?
Strong portfolios typically include a dedicated sketchbook section with dozens of gesture drawings and life studies. Quantity matters less than consistency — regular practice over months shows far better than a last-minute cram.
Can I learn the 12 principles from books alone?
Books like The Illusion of Life and The Animator’s Survival Kit are essential reading, but they work best alongside hands-on practice and critique. Animation is a craft learned through repetition and feedback.
Which software should I learn first?
Start with whatever your target studios use, but don’t let software delay your drawing. The principles transfer across 2D, 3D, and stop motion — the tools are just different brushes.
How long does it take to build a competitive animation portfolio?
Most of our students spend six to eighteen months of consistent practice before applying to programs or studios. Progress depends heavily on weekly drawing hours and how actively you seek critique.
Mastering the 12 principles through steady figure drawing and gesture drawing practice is the surest path to a strong animation portfolio — there are no shortcuts, but there is a clear road. If you’re ready to put in the hours with guidance, we’d love to see you in one of our Montreal art classes. Bring a sketchbook, bring curiosity, and we’ll take it from there.
