A font is a particular size, weight, and style of a typeface. In metal typesetting, each font is a matched set of type, with a piece (a "sort") for each glyph, and a typeface consists of various fonts that share an overall design. In the 21st century, with the advent of computer fonts, the terms "font" and "typeface" are often used interchangeably, although the term "typeface" refers to the design of typographical lettering, whereas the term "font" refers to the specific style of a typeface, such as its size and weight.
There are several tools available to identify fonts from an image, such as WhatFontIs, WhatTheFont, Font Squirrel Matcherator, and Fontspring Matcherator. These tools use advanced AI to find the font in most cases, but low-quality images can cause some misses. Some of these tools are available as apps for iOS and Android devices.
