🎬 The 12 Principles of Animation
Master the timeless fundamentals that bring characters and stories to life
Squash and Stretch
The most important principle that gives weight and flexibility to drawn objects. When something moves, it compresses and extends to show the impact of forces while maintaining consistent volume.
Anticipation
Prepares the audience for a major action by showing preparatory movement. This makes the action more realistic and helps direct the viewer's attention to where it will occur.
Staging
Presenting ideas clearly through camera angles, lighting, and character positioning. The goal is to direct attention and make the story point unmistakably clear to the audience.
Straight Ahead & Pose to Pose
Two fundamental animation approaches. Straight ahead creates spontaneous, fluid action by drawing frame by frame. Pose to pose uses key positions for more controlled, planned animation.
Follow Through & Overlapping
Different parts of a body or object move at different rates. Some elements continue moving after the main action stops, creating more natural and believable motion.
Slow In and Slow Out
Objects need time to accelerate and decelerate. Adding more frames at the beginning and end of movements, with fewer in the middle, creates more convincing motion.
Arc
Most natural movements follow arched trajectories rather than straight lines. This principle ensures that characters and objects move in visually pleasing and realistic curved paths.
Secondary Action
Additional movements that support and enhance the main action. These subtle animations add richness and dimension without competing for attention with the primary movement.
Timing
The spacing of actions in time, determined by the number of frames. Proper timing gives meaning to movement, conveying weight, size, and emotional state of characters.
Exaggeration
Pushing actions, expressions, and poses beyond normal limits to make them more dynamic and appealing. Exaggeration adds excitement and helps convey emotions effectively.
Solid Drawing
Understanding three-dimensional space, weight, balance, and anatomy. Even in 2D animation, characters should feel like they have volume and exist in believable space.
Appeal
Characters and designs should be engaging and pleasant to watch. Appeal doesn't mean cute - even villains need visual appeal through interesting design and clear personality.
12 animation principles crafted by Disney legends Ollie Johnston and Frank Thomas, are the DNA of motion. They’re what make a bouncing ball feel alive, a character expressive, and every movement believable. Whether you animate in After Effects, Blender, Toon Boom, or with pencil and paper, mastering these principles will elevate your craft from “meh” to mesmerizing.
1. Squash and Stretch — Giving Life to Form
Squash and stretch isn’t just for cartoon balls—it’s the heartbeat of motion. It creates weight, volume, and flexibility, making everything feel alive.
Example: A bouncing ball stretches as it rises and squashes when it hits the ground. A character’s face squashes when shocked or stretches in surprise.
Applications: Characters, objects, liquids, facial expressions.
Common Mistakes: Too subtle = stiff motion; too extreme = distracts unless intentional.
Pro Tip: Always keep volume consistent. Squash + stretch should never alter the overall mass of the object.
Without it, your animation is just static images playing in sequence. Yawn.
2. Anticipation — The Setup That Hooks
Anticipation is like a drumroll before a magic trick. It prepares your audience for what’s about to happen.
Example: A boxer pulls their arm back before a punch. A character crouches before jumping.
Applications: Every major action—gestures, jumps, expressions, even dialogue.
Common Mistakes: Skipping anticipation makes motion feel abrupt, confusing, or robotic.
Pro Tip: Subtle anticipation works for even small movements, like a hand reaching for a cup.
Think of it as saying, “Heads up, something cool is coming!”
3. Staging — Clarity is Everything
Staging is composition in motion. It ensures the audience immediately understands the action and story.
Example: Tilt a character forward to show determination, slouch to show defeat.
Applications: Storyboarding, camera angles, scene blocking, key poses.
Common Mistakes: Overcrowding the frame or hiding the main action behind objects.
Pro Tip: Use silhouettes to test clarity—if the pose reads in black and white, it works.
A well-staged scene tells the story before a single frame moves.
4. Straight Ahead vs. Pose-to-Pose — Chaos vs. Control
Straight Ahead: Draw each frame in sequence. Great for fluid, unpredictable motion.
Pose-to-Pose: Define keyframes first, then fill in-between frames. Ideal for planning and control.
Pro Tip: Blend both: pose-to-pose for structure, straight-ahead for natural flow.
It’s like cooking: one method improvises, the other follows a recipe. The tastiest animations mix both.
5. Follow Through & Overlapping Action — Momentum Matters
Follow-through ensures parts of a character keep moving after the main action stops. Overlapping action means different parts move at slightly different times.
Example: Hair sways after a head turn; clothes lag as the body stops.
Applications: Characters, animals, props, vehicles.
Common Mistakes: Everything stops simultaneously—robotic and lifeless.
Pro Tip: Heavier objects move slower. Think elasticity, weight, and inertia.
Without it, motion looks stiff, like PowerPoint animations from 2005.
6. Slow In and Slow Out — Motion With Rhythm
Objects accelerate and decelerate naturally. Slow in and slow out (ease-in, ease-out) mimics real-world physics.
Example: A car accelerates slowly, speeds up, then slows to a stop.
Applications: Character movement, camera pans, object animation.
Common Mistakes: Linear motion looks fake and mechanical.
Pro Tip: Use motion curves in digital tools to fine-tune acceleration for smoother, realistic motion.
It’s like easing into a hug instead of slamming into someone headfirst.
7. Arc — Nature’s Path
Everything in nature moves in arcs: leaves falling, arms swinging, birds flying.
Example: A swinging sword follows an arc, not a straight line.
Applications: Limbs, projectiles, camera paths.
Common Mistakes: Straight-line motion feels unnatural unless mechanical.
Pro Tip: Visualize motion paths in software; smooth curves = professional polish.
Straight lines are for spreadsheets, not life.
8. Secondary Action — Personality in Motion
Secondary actions enhance the main action, adding flavor and depth.
Example: A character walks (primary), while tapping their foot (secondary).
Applications: Gestures, props, facial expressions, small quirks.
Common Mistakes: Overdoing it, distracting from the main action.
Pro Tip: Use secondary actions to reveal personality subtly.
Think jazz hands—optional but oh-so-satisfying.
9. Timing — The Soul of Motion
Timing defines weight, speed, and emotion. Slow, heavy movements convey sadness; quick, light motions show energy.
Example: A sad walk is slow and measured; a happy bounce is fast and rhythmic.
Applications: Dialogue, fight sequences, comedic beats, dramatic moments.
Common Mistakes: Uniform timing feels lifeless; ignoring frame counts loses emotion.
Pro Tip: Timing charts help visualize frames per action—experiment for emotional impact.
Timing is your character’s heartbeat—get it wrong, and they’re flatlined.
10. Exaggeration — Amplify Emotion
Exaggeration clarifies actions and heightens emotion, making motion memorable.
Example: Eyes bulge in shock, character flops dramatically when sad.
Applications: Comedy, dramatic storytelling, key poses.
Common Mistakes: Too subtle = boring; too extreme = distracting.
Pro Tip: Exaggerate to communicate, not to confuse.
In animation, bold moves beat realism every time.
11. Solid Drawing — Foundations Matter
Even digital animation needs solid fundamentals: weight, volume, perspective.
Example: A character rotating in space must maintain consistent form.
Applications: Character design, posing, 3D rotations.
Common Mistakes: Flat or inconsistent shapes; broken perspective.
Pro Tip: Always imagine your character in 3D space, even in 2D animation.
Solid drawing = skeleton; the other principles = muscles, skin, and soul.
12. Appeal — Charm Your Audience
Appeal makes characters memorable and relatable. It’s not just “cute”—it’s charisma in motion.
Example: Mickey Mouse, SpongeBob, or quirky sidekicks.
Applications: Character design, expressions, gestures, personality.
Common Mistakes: Bland, generic designs.
Pro Tip: Appeal is the combination of visual clarity, engaging design, and personality that resonates. Test readability in silhouette.
Appeal is why we root for characters—even the weird ones.
