Interborough collects the inconsistent characteristics of those signs and combines with a personal touch to create a new, unique design itself. The sans-serif typeface explores the American, compact modular style and try to balance the solid, geometric form with subtle curviness in minor eccentric details. Interborough employs a confident and optimistic look that is found in visual designs of early 20th century. In short, Interborough is unique but familiar, structured but versatile, nostalgic but up-to-date.

Functionality wise, in a nod to its origin, Interborough is highly optimized for signage & wayfinding usage, especially with the support of the extra exclusive glyphs for street suffix, honorific titles, arrows, etc. At the same time, Interborough also strives to be a functional, legible text-based typeface. The complimentary lowercase set, which did not exist in the original inspiration, is designed with a relatively large x-height to support legibility and readability. Due its nature being a condensed sans-serif, Interborough is suitable for a shorter to medium body of text that attracts attention rather than a longer body of text that requires unobtrusive fluidity.
