Frankfurt Flag

The flag of Frankfurt am Main is a simple bicolor design, officially described as a horizontal triband of red-white-red. The central white stripe is twice the height of each of the two red stripes, creating a distinctive and balanced visual proportion. This civic flag is used by the city government and flown on municipal buildings, representing the city's identity and autonomy.

While the bicolor is the primary civic flag, the city also possesses a more elaborate state flag or service flag (Dienstflagge). This version features the same red-white-red background but is defaced with the city's coat of arms centered on the white band. The arms add significant heraldic complexity to the otherwise straightforward design of the basic flag.

The colors are precisely defined for official use, with the red specified as Pantone 485 C or its equivalents in other color systems. This ensures consistency in reproduction across various media, from physical fabric to digital displays. The flag's design is deeply rooted in the city's historical heraldic traditions, which date back to the medieval period.

The red and white colors are the traditional heraldic tinctures of Frankfurt, directly derived from its coat of arms. These colors have been associated with the city since at least the 13th century, symbolizing its long history and status as an Imperial City within the Holy Roman Empire. The specific arrangement of the stripes is a modern formalization of this ancient color scheme.

On the state flag, the central coat of arms carries deeper symbolic meaning. The silver eagle on a red field represents Frankfurt's historical connection to imperial power and its former role as an Electoral City. The eagle is a classic symbol of authority and freedom in German heraldry, underscoring the city's historical importance and self-governance.

The use of red and white as the city's colors is documented from the 13th century, appearing on seals and banners. The current, precisely defined form of the red-white-red bicolor was formally adopted in the 20th century, following the standardization of German municipal flags. The design codifies a color combination with centuries of continuous use.

The coat of arms featuring the eagle was officially granted in the 14th century and has undergone stylistic revisions over time. Its incorporation into the state flag follows the common German practice of distinguishing between a simple civic flag (Bürgerflagge) and an official service flag for government use.
