Big fonts are typefaces that are designed to be larger than normal sizes. They are used to draw attention to specific words or phrases, to create impact and grab the reader's attention. They are often used in branding, advertising, headlines, titles, and subheadings, as well as in various types of digital and print designs. Big fonts are available in a variety of styles and designs, ranging from clean and minimalist to bold and expressive, and can be customized to suit different needs and preferences.
