Abstract
Sans serif typefaces, which were first developed in the early 19th century, were designed to be eye-catching rather than beautiful, due to the demand during the Industrial Revolution. In the 1920s, a clear “functional beauty” was discovered by introducing geometric structures into serif-free typeface designs, and they became widely used throughout the 1930s. After World War II, the decline of modern sans serif typefaces led to the elimination of monotonous, uniform strokes, emphasizing the modulation of thickness while leaving the handwritten mark of the letters. Furthermore, the characteristics of classical Roman typefaces were introduced, resulting in the creation of the humanist sans serif, which combines old and new. The designer who designed it was also a calligrapher, and it can be said that his mastery of handwritten letters gave it the readability required for body text.
