What scale are the Playmobil?

Defining the Playmobil scale is not trivial. First of all because the Playmobil figure itself is no longer realistic, since it does not keep the proportions of a human between the head and the rest of the body.
But based on their height we could say that the Playmobil scale is 1:24, although their vehicles could be more similar to the 1:18 scale.
