Fair N Square by David Kerkhoff is a free techno display font with tall, rectilinear lettering and a stark architectural profile. Its strokes stay mostly uniform, with squared arches, flat crossbars, abrupt right-angle turns, and unusually open joins. The extreme height is the defining feature.
Digital graphics are a natural setting for these severe, machine-cut forms, especially crisp interface titles, electronic music artwork, and science-fiction game menus. The same narrow geometry also suits futuristic event posters and technology branding, where the lettering can resemble a printed circuit or custom industrial control-panel label.
