The main difference is between regular and bold fonts. Regular fonts are usually used for headings, body text, and other areas where the font size is large. Bold fonts are generally used for titles and other areas where the font size is small. There are also a number of different weights for each type of font. Thin fonts are generally used for headings and body text, while medium weight fonts are often used for subheadings and other smaller areas. Heavy weight fonts are generally used for larger headers, paragraphs, and other areas that need to stand out on the page.
