Which Country Has the Longest Coastline
Canada has the longest coastline in the world, stretching about 202,080 kilometers (125,567 miles). Its coast borders the Pacific, Atlantic, and Arctic oceans, giving it the most shoreline of any nation.
Why Canada's Coastline Is So Long
Canada's coastline is extremely long because of its many islands, deep fjords, and complex shoreline shapes. The Arctic Archipelago alone adds thousands of kilometers, and measuring every inlet and island increases the total length significantly.
How Coastline Length Is Measured
Coastline length depends on measurement scale and method. Smaller measurement units capture more detail, so fractal-like shorelines appear longer. The World Factbook and other sources use standardized data, but exact rankings can vary by source.
Why Long Coastlines Matter
Long coastlines support shipping, fishing, and marine research. They also affect national defense, border management, and climate patterns. Countries with extensive coastlines often have strong maritime economies and strategic importance in global trade routes.
