Animation is an extraordinary art form that brings stories, characters, and worlds to life in dynamic ways. Whether it’s in feature films, television shows, video games, or even advertisements, animation serves as a medium to convey emotions, ideas, and dreams in a way that no other medium can. However, creating effective animation requires much more than drawing and rendering. A set of core principles, known as animated rules or “principles of animation,” serve as the foundation for creating engaging and believable motion.

ToggleIn this blog post, we’ll explore these essential animated rules, examining their origins, applications, and how they contribute to the craft of animation. Whether you’re an aspiring animator or simply a fan of animated works, understanding these principles will help you appreciate the magic behind the scenes.
The 12 Principles of Animation
The 12 principles of animation, developed by Disney animators Ollie Johnston and Frank Thomas in the 1930s, are the cornerstone of traditional animation. These principles ensure that animated characters feel alive, believable, and full of personality. Let’s break them down:
- Squash and Stretch
Squash and stretch is the most fundamental principle in animation, bringing a sense of weight, flexibility, and gravity to animated objects. This principle allows for exaggerated movements that make characters feel alive and grounded. By stretching a character’s body or face or squashing it in certain ways, animators can evoke emotion, humor, or drama. - Anticipation
Anticipation is the preparation phase before a major movement occurs. Whether it’s a character crouching before jumping or winding up their arm before a throw, anticipation sets up expectations for the audience. Without anticipation, action would seem sudden or out of place. - Staging
Staging refers to the way an action or scene is framed to ensure that the audience can clearly read the emotion, focus, and significance of the moment. This principle deals with the positioning of characters, objects, and the camera to guide the viewer’s attention. A well-staged scene ensures clarity in the storytelling. - Straight Ahead Action and Pose-to-Pose
These two approaches to animation involve different methods of creating motion. Straight ahead action is when animators draw frames one by one in a continuous sequence, creating fluid and unpredictable motion. Pose-to-pose, on the other hand, involves key poses being established first, and the in-between frames are filled in later. Both techniques have their benefits, but combining them can lead to more dynamic and expressive animation. - Follow Through and Overlapping Action
Follow through is the idea that once a character has moved, their parts (such as hair, clothes, or limbs) continue moving due to inertia. Overlapping action refers to the offset timing of different body parts, where each part of a character moves at a slightly different rate. These principles make movement more natural and realistic. - Slow In and Slow Out
To achieve more realistic motion, slow in and slow out refers to the gradual acceleration and deceleration of a character’s movement. For example, a car starting to drive will move slowly at first, then pick up speed, and finally slow down before stopping. This principle ensures smooth, believable movement. - Arc
Most natural movements follow an arc or curve rather than a straight line. By incorporating arcs into animation, animators create more fluid, organic motion. Whether it’s the swing of a pendulum or the movement of a character’s arm, arcs help give movement a sense of grace. - Secondary Action
Secondary actions are additional motions that complement the primary action. For instance, while a character is walking (primary action), their arms might swing, or their clothes might ripple (secondary actions). These details add depth and richness to the animation, making it feel more alive. - Timing
Timing refers to the number of frames used to depict a particular action, which affects the speed and rhythm of the movement. Proper timing ensures that actions are neither too fast nor too slow and that they fit with the desired emotional tone. For example, a punch might take a few frames to land for a dramatic effect, while a quick, playful gesture might only take one or two frames. - Exaggeration
Exaggeration is a vital part of animation that pushes actions, expressions and poses beyond what is realistically possible. This doesn’t mean distorting the essence of a character or story, but rather amplifying certain characteristics to convey emotion, energy, or humor. Exaggeration brings life and fun to the animation, making it visually striking. - Solid Drawing
Solid drawing ensures that characters and objects feel three-dimensional and have weight. This principle requires animators to have a strong understanding of anatomy, perspective, and volume, allowing them to create believable, solid characters that inhabit their worlds convincingly. - Appeal
Appeal refers to the quality that makes a character or design engaging, charismatic, and likable. It doesn’t just refer to attractiveness but also to the character’s personality, style, and design. Appeal ensures that the audience feels a connection to the character, making them compelling and memorable.
Animated Rules in Digital Animation and 3D Animation
While the 12 principles of animation originated in traditional 2D animation, they are still widely applied in digital and 3D animation. However, the techniques have evolved to accommodate new technologies and mediums.
In digital animation, the principles remain the same, but the tools have changed. Software like Autodesk Maya, Blender, and Toon Boom allows animators to create intricate 3D models, simulate complex environments, and apply dynamic lighting and textures. Digital tools have expanded the creative possibilities of animation, but the core principles, like timing, appeal, and squash and stretch, still play a crucial role in crafting effective animation.
3D animation introduces additional challenges, particularly in the realms of rigging and character control. Rigging is the process of creating a skeleton for a 3D model so that it can be manipulated and animated. Unlike 2D animation, where each frame is drawn individually, 3D animators manipulate models in a 3D space, adjusting bones, joints, and weights to create movement. Despite these differences, the principles of anticipation, follow-through, and timing are just as important in 3D as they are in 2D.
For instance, in movies like Toy Story or Frozen, animators use the principles of anticipation and follow-through to make characters like Woody or Elsa feel like they are truly part of the world around them, even though they are created digitally. The fluidity of these 3D characters is the result of applying classic animation principles to modern techniques.
The Importance of Breaking the Rules
While these principles are essential for creating realistic and engaging animation, there are times when breaking the rules can lead to more creative and artistic results. Animation is an expressive medium, and sometimes bending or twisting the principles can add unique flair or emotional depth to a scene.
For example, animators often exaggerate certain actions or use non-realistic motion to convey an emotional state, like in the works of surrealist animator Jan Švankmajer, whose films push the boundaries of what traditional animation can do. By intentionally distorting the principles of animation, artists can create experiences that are more abstract, symbolic, or avant-garde.
Conclusion: Mastering Animation and Its Rules
In conclusion, the world of animation is both complex and fascinating, offering endless opportunities for creativity and expression. The animated rules provide a strong foundation for animators to create motion that feels organic and compelling. By mastering these principles, animators can bring their characters to life in ways that resonate with audiences, evoke emotions, and tell powerful stories.
However, the true beauty of animation lies in its ability to adapt and innovate. Whether through traditional 2D hand-drawn techniques or cutting-edge 3D animation, the principles of animation continue to shape the industry and inspire new generations of artists. As animation technology evolves, so too will the possibilities for creativity, but the fundamental rules will always be the backbone of great animated works.
