How simple fonts can make your product feel easier to use
The font you use on your pricing page or user manual shapes how difficult your product feels. Psychologists found that when instructions are printed in an easy-to-read font like Arial, people estimate the task will take 8 minutes. When printed in a difficult, decorative font, they estimate it will take 15 minutes. High cognitive fluency translates directly into higher sales and fewer abandoned checkouts.
The Invisible Effort of Reading
Every time the human brain encounters a piece of written text, it performs two distinct operations simultaneously. The first is decoding the visual presentation—identifying the shapes of the letters, distinguishing them from the background, and assembling them into recognized words. The second operation is comprehending the underlying message. While conscious awareness focuses almost entirely on the meaning of the words, the subconscious mind continuously monitors how difficult the visual decoding process feels.
This subjective ease or difficulty of information processing is known in psychology as cognitive fluency. When visual inputs are crisp, clear, and familiar, the brain experiences high perceptual fluency. Processing feels fast and effortless. Crucially, the brain does not neatly separate the sensation of reading from its evaluation of the topic being read. Instead, it frequently misattributes the ease of reading the words to the inherent qualities of the underlying task or object itself.
The Font Experiment on Perceived Effort
The direct connection between typographic clarity and perceived effort was famously demonstrated in research by psychologists Hyunjin Song and Norbert Schwarz. In their experiments, participants were given identical step-by-step instructions for an exercise routine. One group read the instructions printed in Arial, a clean and standard sans-serif typeface. Another group read the exact same instructions printed in a difficult, decorative script font like Brush Script.
Even though the actual exercise routine described was identical word for word, participants who read the text in Arial estimated that the workout would take approximately 8 minutes to complete. Those who read the decorative font estimated that the same workout would take around 15 minutes. Furthermore, participants who read the harder-to-read font judged the exercise routine as requiring significantly more effort, skill, and discipline, and they were far less willing to make it a part of their regular daily routine.
