Users perceive objects in the simplest form possible.
The Law of Pragnanz, also known as the Law of Simplicity or Good Figure, is a principle in Gestalt psychology. It states that people will perceive and interpret ambiguous or complex images in the simplest form possible, often reducing the perceived object to its most basic and recognisable shape.
Background
Originating from Gestalt psychology, the Law of Prägnanz is one of the many laws that describe how humans perceive visual elements. Gestalt psychology emphasises that the human mind tends to perceive objects as part of a greater whole and will simplify complex images into simpler forms. This law plays a crucial role in understanding visual perception and how people make sense of the world around them.
Law of Pragnanz Design Example
Consider a website’s logo. If it’s too intricate with many details, users might not remember or recognise it easily. However, if the logo is simple and clear, like Apple’s apple or Nike’s swoosh, it’s instantly recognisable and memorable. Similarly, in app designs, simple icons without too much detail are more easily understood and remembered by users than complex ones.

Design takeaways
- Simplicity is Key
Avoid overcomplicating designs. The simpler and clearer, the better. - Reduce Clutter
Too many elements can confuse users. Stick to essential components. - Use Recognisable Patterns
Familiar shapes and patterns are easier to understand. - Prioritise Clarity
Ensure that the main message or function is clear and not lost in the design.
