Total areas including water are also given, but when ranked by total area, a number of coastal cities appear disproportionately larger. San Francisco is an extreme example: water makes up nearly 80% of its total area of 232 square miles (601 km 2).

In addition to coastline lengths, this is the source of the land area used to calculate the "coast/area ratio" for both TWF and WRI (see below) coastline measurement. This ratio measures how many metres of coastline correspond to every square kilometer of land area. The ratio illustrates the ease of accessibility to the country's coast from ...
