 12 Principles of Animation


When we dive into the world of animation, we encounter certain principles that are used to recreate the movements of life and present it to the audience from an artistic point of view. These principles are the "12 Principles of Animation" laid out in the 1930s by Ollie Johnston and Frank Thomas of Walt Disney Productions and detailed in "The Illusion of Life: Disney Animation". These principles are the cornerstones for creating the depth, movement, and expression of animation.


1. Squash and Stretch: This principle refers to the flexibility and weight of objects and
characters in animation. Objects compress and expand as they move, giving the movement
dynamism and realism.
 
2. Anticipation: It is the character's preparatory action before acting. This
helps the viewer anticipate what will happen and makes the movement more understandable.
 
3. Staging: Elements such as the character's poses, movements, and scene arrangement are
used to make the story understandable and interesting.
 
4. Straight Ahead Action and Pose to Pose: These two different animation techniques
determine the continuity and rhythm of the movement. While direct action requires
continuous drawing from the beginning to the end of a scene, pose-to-pose involves drawing
key poses first and then adding intermediate frames.

5. Follow Through and Overlapping Action: This means that some body parts continue to move
even after a character's movement has stopped, or different body parts move at different
speeds to increase the realism of the movement.
 
6. Slow in and Slow Out: Movements usually start slowly, speed up, and then slow down.
This principle makes it look more realistic.
 
7. Arc: The movements of living beings are generally non-linear and follow an arc or circular
orbit. This principle refers to the reproduction of these natural movements in animation.
 
8. Secondary Action: Additional actions that support the main action and further deepen the
character's feelings or thoughts.
 
9. Timing: Controlling the speed and rhythm of movements greatly affects the liveliness and
the expressiveness of the animation.
 
10. Exaggeration: Exaggerating a character's movements, expressions, or emotional reactions
going a little beyond reality adds energy and charm to animation.
 
11. Solid Drawing: It is the principle of applying the rules of perspective, weight, and volume
to make the animation feel three-dimensional and the weight of the characters.
 
12. Appeal: The need for characters to be engaging and empathetic to the audience. This is
achieved through character design, movement, and expressions.
 
The 12 principles of animation provide a foundation for understanding and practicing the art
of movement and expression. Most modern animation studios continue to apply these
principles to bring life and expression to their animations.
