The flag is based on that of the Abbot of St. Gallen, who was the feudal lord of Appenzell until 1403. The flag of the abbey showed a bear on a yellow field, and the independent territory Appenzell changed the field to white for its own flag. Before its independence, Appenzell had a flag of a bear statant (on all fours) on a honeycombed field, attested from 1377.
Appenzell split into its two half-cantons as a result of the Swiss Reformation, in 1597.
Most mass-produced flags are commonly 150x90cm / 5x3' or 90x60cm / 3x2', which will often vary from the official size ratio. We now offer a custom-manufactured official size option for our many of our flags.
