Letter and word combinations are defined by the contrasting anatomy of perfect circles and hard corners that appear in unconventional relationships. Many letters that are usually rounded are square instead, and many typically angled forms are circular.

Boulder Mono was created to have a shapely, energetic feel. At large sizes the type is fluid and geometric. The tone is clean and visually arresting. When set as text, the type presents a typical monospaced rhythm, offset by a raw and unique reading atmosphere.

The ten style Boulder Mono family consists of a broad range of weights and features split-style italics that creates a visually dynamic emphasis. The split italic takes advantage of the geometric form as letters are divided and offset on key structural points.

While Boulder Mono is by no means a traditional text face, it is still a very legible and useful typeface when used appropriately. Dynamic and structural at large sizes, Boulder Mono is exceptionally legible at small sizes.

Boulder Mono has been designed so that the geometric styles simulate conventional letterforms when viewed at small sizes. Settings at 12pt and less will appear more fluid and traditionally legible than larger sizes.

The split forms of the italics are particularly idiosyncratic at large sizes. The letterforms are playful and deconstructed. However, when used at small sizes the italics compress to appear oblique, creating a more typical italic feel.
