Font Classification: As typography progressed over time there came to be genre's within the field. This led to a system to differentiate typefaces based on thickness, serif's, improved techniques of print with more contemporary inks and paper. Designers began using techniques from different eras to form new typefaces using both new and old elements.
Old Style fonts originated from the Renaissance era which led to the fonts appearing "warm" and "friendly." It is based on handwriting and often has a noticeable contrast with thick and thin strokes. Bracketed serifs are an important element as well.
Examples: Caslon, Garamond, and Palladium
Transitional: Coming from the 18th century, this style combines Old Style features with broad nib pen writing along with a new system of using metal engravings.
Examples: Newton, Petersburg, ITC New Baskerville, Bachenas
Modern: After the introduction of the metal engraving system, this style became known for using a strong contrast between the widths of letters. Serifs tended to be long and thin with strictly vertical axes.
Example: Bodoni, Neva, and Selina
Slab Serif: This style differs from serifs because of a noticeable use of thick square-ended serifs. This was popular in the mid-19th century. Usually all strokes are of a similar width with a large x-height.
Examples: Luxor, Clarendon, Ziggurat
Sans Serif: This style became known as the "bare minimum" due to the lack of serif aspects, like a "tail." They became popular in the mid-19th century by the introduction of type being carved into wood.
Examples: Akzidenz Grotesk, Gill Sans, Futura
Script: Similar to handwriting, the fonts in this family vary and have been in existence since people have been writing. These fonts have a dynamic, fluid, and imperfect form. Usually these fonts are used for something formal, like a wedding invitation.
Example: Brush Script, Sonora, Choc, Mistral
Blackletter: These recognizable and memorable fonts are often used for headlines, labels, and even tattoos. Even though some fonts in this category can be difficult to use, it is one of the most popular types of font.
Examples: San Marco, Fette Fraktur, Engravers Old English
Grunge: "Sketchy" is the best way to describe this category. There are no clear, set descriptions of this style but many are a variation of another font. This became popular along with the Grunge musical movement.
Examples: MC Auto, Turbo Ripped, Laundromat
Monospaced: In this category, all letters are evenly spaced with the same width, this resembles the way a typewriter works. This leads to letters being nonproportional because they each take up the same amount of space by expanding or condensing.
Examples: Courier, Orator, OCR B
Undeclared: These fonts use both serif and sans serif characteristics. They mostly have sans serif form with flared serif elements
Examples: Optima, Beorcana, Copperplate Gothic
