The length of England's coastline is approximately 2,000 miles (3,200 km).1
It is important to note that this figure is not a fixed, absolute value. Due to the coastline paradox, the measured length of a coastline varies depending on the scale of measurement used. Because coastlines are fractal in natureāfeaturing complex curves, bays, and inletsāusing a smaller measuring scale reveals more detail, which in turn increases the total measured length.2
