Type design is the art and craft of creating and modifying typefaces, which are sets of characters that include letters, numbers, and symbols. Designers focus on aspects like shape, size, and spacing to ensure that text is legible and visually appealing. Each typeface can convey different emotions and styles, making it an essential element in graphic design and branding. The process involves sketching ideas, refining them digitally, and testing how the typeface looks in various contexts. Famous type designers, such as Matthew Carter and Adrian Frutiger, have created iconic typefaces that are widely used in print and digital media, influencing how we read and perceive text.
