Optical Illusions in Type Design: A Guide for Graphic Designers
The Importance of Awareness in Font Design
Type designers know that letter forms can play tricks on our perception. Sometimes an equal amount of space between letters looks wrong, requiring kerning adjustments. Sometimes a stroke of the same width can look thinner or thicker depending on whether it’s vertical or horizontal. It’s essential to be aware of such illusions in font design, as they can significantly impact the overall look and feel of a design.
7 Optical Illusions to Be Aware Of
Nostalgic Dolphin, a design studio specializing in branding, typography, and UI/UX design, has created a blog post that highlights 7 optical illusions that every graphic designer should know. The studio’s founder, Igor Petrovic, has curated a list of illusions that can affect the way we perceive shapes and lines in type design.
The Overshoot
The overshoot is an optical illusion that causes curved or pointed shapes to look larger or smaller than shapes that end with flat lines. This can be particularly problematic when designing fonts with curved or pointed serifs.
The Bone Effect
The bone effect is another common optical illusion that causes a disjointed look where a straight line meets a half-circle. This can be mitigated by using an ink trap, which helps to create a smooth transition between the two shapes.
Sharp Joint Darkening
Sharp joint darkening is an illusion that causes a union to look heavy when two lines cross at a sharp angle. This can be addressed by using a subtle curve or a slight adjustment in the angle of the lines.
Other Optical Illusions
Other optical illusions that designers should be aware of include the Ponzo illusion, which causes parallel lines to appear non-parallel when one line is placed behind a curve; the Hermann grid illusion, which creates the illusion of gray dots where none exist; and the Kanizsa triangle, which creates the illusion of a triangle where none exists.
Conclusion
By understanding these optical illusions, designers can create more harmonious and effective typography. By being aware of these visual tricks, designers can avoid common pitfalls and create fonts that are both aesthetically pleasing and easy to read.
