Look at a standard world map, and Canada looks big, but not that big. The secret is in the fractal nature of coastlines—all those tiny islands, fjords, and inlets add up like crazy. Canada has over 52,000 islands, including the entire Arctic Archipelago. Every little bump and bay is measured, and the official surveyors don’t miss a single rock. It’s like measuring a crumpled piece of paper: the more you zoom in, the longer the edge gets. Meanwhile, countries with smooth, sandy coasts—like Brazil or the United States—look tiny in comparison.
But wait, what about Russia and Indonesia? They’re huge too!
Russia comes in second—around 37,653 kilometers—which is still massive, but barely a third of Canada’s total. Indonesia, with all its thousands of islands, clocks in at about 54,716 kilometers (yes, more than Russia, but still a distant second to Canada). Here’s the irony: Indonesia has way more swimmable beach, but the official measurement game is rigged by Canada’s endless Arctic fjords. So if you want to brag about “coastline length,” you need a lot of jagged, frozen inlets—not just warm sand. (Nature’s weird sense of humor, right?)
Which Country Has the Longest Coastline in the World? List of the 7
“But what about Australia?” I hear you ask. Good question! Australia has about 25,760 kilometers—beautiful, but a pipsqueak compared to the top three. The US, including Alaska (which is a cheat code), has roughly 19,924 kilometers. So if you want to visit the longest coast, you’re basically booking a trip to Canada and hoping you don’t need a parka in July.
