This is referred to as the coastline paradox. A coastline is fractal-like — which means that it has self-similar properties, similar at every scale — therefore the closer the observer looks, the more detail is revealed, leading to a greater overall length. The United Kingdom's coastline is more broken than coastlines of many other countries. It has a fractal or Hausdorff dimension or 'wiggliness' of 1.25, which is comparatively high; the Australian coastline for example
