Letterforms: Typeface Design from Past to Future Hardcover – Illustrated, July 3, 2018 by Timothy Samara
Letterform literally translates to mean the form of letters. To truly understand what this means and what the specific characteristics of letterform are, we must first understand the basic design relationship between Form and Content.
The very fact that there is both FORM and CONTENT is one of the factors that distinguishes Design from mere Decoration. At the most basic level, FORM is HOW something looks and Content is WHAT it is. So, FORM is being addressed when we are considering options of color, media, material, size, shape, texture, style, etc.—the aesthetic. Virtually any decision that will determine of affect the LOOK of the thing being created. That thing could be a sculpture, a poster, a painting or a letter of the alphabet. So, some specific examples of variables that affect the FORM of letters are stroke weight, type of serif, x-height, scaling, posture, etc.
By comparison, CONTENT is created when we are considering the purpose, message, meaning, information, facts, sequence, story telling, etc. The design concept of Form Follows Function is basically saying that the look (FORM) of the thing being created is not the first thing to consider. Instead the designer must first have a solid understanding of the purpose or message (CONTENT) and then make the aesthetic decisions that will shape the FORM.
So, back to letterform. It follows from above that letterform is then, not meaning, message, purpose—CONTENT. But instead letterform is concerned with any and all the individual characteristics or variables that influence the aesthetic look of letters. We see the result of some of the infinite possible combinations of these typographic variables as different typeface families, and even further as fonts within a type family. We also see that different combinations of variables can create, add to, or influence different feelings or moods and therefore enhance or influence the overall design message that may also include images, style of layout, choice of media or material, physical location/context, color psychology, etc.
A type designer is very aware of these potential effects of manipulating the variables that create letterform (and also the above mentioned relationship between FORM and CONTENT). Because of this, a type designer is rarely (if ever) designing a typeface simply to create a “cool” or “pretty” typeface. Instead it would be much more common to have a design goal in mind such as “more readable on the computer screen” or “evoke contemporary technology), or even “sturdy readable and subtle personality”, etc. Luckily for the rest of us, type designers have created millions of typefaces for us to choose from with these goals in mind. However, we do need to be aware of the same variables that they (the type designer) tweaked in specific combinations for specific effects. With this awareness we can then make intelligent design decisions when choosing type and pairing it with or complimenting the overall design message.
Some letterform variables can be used to categorize typefaces into specific Style Category groupings:
- Serif
- (the slope or “bracket” that transitions from the stroke of the letter to the serif is a specific characteristic that is in combination with and varies with the type of serif that is used.)
- Old Style Roman

- Transitional Roman
- Modern Roman

- Slab
- Sans-serif
- Script
- Novelty
- Calligraphic
Type variable of Horizontal Scaling (this, as well as vertical scaling, is obviously a method of distortion. Use only with extreme discretion.)

- Condensed
- Extended
Type variable of Posture (Forward posture is normally referred to as Italicizing the form. Its specific form of emphasis usually results in implying a personal statement. Back slant is rare, and would qualify as a special effect. Besides these two extreme postures, most typefaces are quite vertical or close to it.)
- Italics
- Backslant
Type variable of Stroke Weight (this is different from the overall width of a letter. It refers to the stroke only.)
- Variable-weight
- Mono-weight
- thin/light
- regular
- semi bold
- bold
- ultra bold
- Heavy
- Black
Type variable of x-Height (Generally speaking, an x-height that is above mid-point will result in greater readability without increasing the point size of the letter. Conversely, an x-height that is lower than mid-point will lower readability but will generally be regarded as “stylish”.
