The left‐right positions of the political parties in Sweden, Norway, Denmark, Finland, and Iceland are compared from the late 1970s to the beginning of the 1990s. To locate the parties, survey data on the voters' self‐placements along the left‐right continuum are used. In order to study changes in the left‐right polarity and the degree of consensus along the left‐right continuum in each of the countries, we use the mean party positions to calculate three different measures of party distances. The wing party distance is that between the party farthest to the left and the party farthest to the right. The rival party distance is that between the Social Democratic Party and the traditional Conservative Party. Finally, the mean party distance is the average distance between all pairs of parties. One of the main conclusions is that in Sweden and Iceland the left‐right continuum seems to contract, whereas in Norway and Denmark the left‐right polarity and the distances between the parties are increasing. In today's Nordic party space, the distance between left and right is longest in Denmark and shortest in Norway. Eventually, 39 Nordic parties are brought together on the same left‐right scale. The analysis reveals that there are some clearly distinguishable clusters of parties or party families in the Nordic countries, such as, for example, the socialist parties, the social democratic parties and the conservative parties. Other party groups differ greatly in left‐right position, like the progressive parties, the liberal parties and t
