A typeface is a set of characters that share a common design, including letters, numbers, and symbols. Each typeface has its own unique style, which can convey different emotions or messages. Common categories of typefaces include serif, sans-serif, script, and monospace, each serving different purposes in design and readability. Typefaces are used in various applications, from printed materials like books and magazines to digital platforms such as websites and apps. Choosing the right typeface is essential for effective communication, as it affects how the text is perceived by the reader.
