Motivated by the pursuit of a more balanced alphabet, van den Oudenalder spent more than four decades designing alphabets where each letter occupied the same surface area, adhering to strict, unique guidelines for each design. His designs house a wide range of guidelines, making each alphabet unique in expression and appearance.

The majority of typefaces are optimized for readability and to express a certain characteristic to the reader. Although practical in everyday use, it limits letter creativity and uniformity. For example, due to the introduction of kerning, letters are not directly located below another. Van den Oudenalder therefore focused on monospaced typefaces that keep a certain uniformity and symmetry.

Much of his work was executed on graph paper, with each letter composed of carefully arranged squares. To ensure consistency, he manually counted the squares to calculate the total surface area of each letter. Once an alphabet approached completion all letters would be redrawn on a larger scale, allowing for a more precise square count before finalizing the design.
