At the world championship in St. Moritz she won the slalom and the combined competition and was second in downhill (after Swiss Anny Rüegg).

To this day, Cranz remains the most successful competitor at the World Championships, with twelve gold and three silver medals.

At the 1936 Winter Olympics, Cranz won the newly established alpine combined competition in a spectacular race.

Taking place during World War II with only Germany-friendly athletes, the championship was not acknowledged by the International Ski Federation.
