The term “sans-serif” comes from the French word “sans” meaning “without”, so it’s easy to understand that sans-serif typefaces don’t have the extra flourishes or small lines that serif typefaces do. Helvetica, Arial, and Verdana are some of the most popular sans-serif typefaces.
Because sans-serif typefaces are associated with modernity, simplicity, and clarity, they’re often used in graphic design, advertising, and branding. However, you may want to consider a serif typeface for projects that involve a lot of text or need to be printed, since they are more readable.
