A font is a set of characters with a specific design, style, and size that are used to display text. Fonts can be identified using various font finder tools available online and as mobile apps. These tools use advanced AI to search through their database and compare the fonts to the one in the image. They list all font matches and give a preview of how each looks like as text. Some of these tools also allow users to enter their own text and play with font size for the full experience. The Font Matcherator and Fontspring Matcherator are two examples of font finder tools that search the catalog of over 900,000 paid and free fonts available for download or purchase on their respective sites.
