  • Various sources differ on the number of islands some countries include, likely due to varying definitions between an island, an islet, and an atoll.
  • Listed coastline lengths are subject to the “coastline paradox”, in which the measured length of a coastline gets longer as the unit of measurement (mile, kilometer, meter, foot, etc.) gets shorter. The specific units of measurement used to initially measure each country’s coastline are unknown.
