The subject of the coat of arms refers to Karstula's position as the "gateway to Ostrobothnia", as the inland routes to Ostrobothnia have passed through Karstula in ancient times and still do today. The coat of arms was designed by Ahti Hammar, and the Karstula municipal council approved it at its meeting on 9 March 1953. The Ministry of the Interior confirmed the coat of arms for use on 16 July of the same year.
