Which Country Has The Longest Coastline In The World

Last summer, I was on a beach in Portugal, staring at the endless Atlantic. “This must be the longest coastline in the world,” I thought, while a seagull tried to steal my sandwich. Spoiler alert: I was dead wrong. That gull got my lunch, and my geography got brutally corrected.

You see, Portugal has a gorgeous coast, but it doesn’t even crack the top ten. So, which country actually has the bragging rights for the most shoreline? Prepare to be surprised—it’s not an island nation you’d expect.

The winner is… Canada. Yes, really.

Canada has the longest coastline in the world, stretching a mind-boggling 202,080 kilometers (about 125,567 miles). To put that in perspective—go ahead, grab a coffee, you’ll need it.

That’s four times longer than Indonesia’s coastline, and ten times longer than Australia’s. I know, I know—you probably thought it would be Australia or maybe Russia. But nope, Canada wins the “I’m literally surrounded by water” contest by a landslide.

But why is Canada’s coastline so crazy long?

Here’s the plot twist: it’s not because Canada is huge (though it is). It’s because of fractals. Yes, math just crashed the party. Coastlines are super jagged—every bay, inlet, and tiny island adds kilometers.

Canada’s northern and eastern coasts are full of fjords, archipelagos, and thousands of islands. Think of it like crumpling a piece of paper: the surface area stays the same, but the edge gets ridiculously longer. Canada’s coastline is nature’s crumpled paper.

The Arctic archipelago alone—where polar bears outnumber people—adds tens of thousands of kilometers. And don’t get me started on Newfoundland and British Columbia, which look like someone took a saw to a map.

How does Norway compare? (You were thinking it, right?)

Norway is famous for its dramatic fjords, and yes, it has a long coastline for its size. But it’s no match for Canada. Norway’s coast is about 83,000 kilometers if you count every nook and cranny.

That’s still impressive—enough to wrap around the Earth twice. But Canada’s coastline wraps around the Earth five times. Five. Times. Next time you’re stuck in traffic, remember: in Canada, you could drive for months and never see the same beach twice.

The runners-up (because we love a good ranking)

After Canada, the list goes: Indonesia (around 54,720 km), Russia (37,653 km), and the United States (19,924 km). Yes, the US has a surprisingly short coastline compared to Canada. Alaska helps, but still—Canada is the undisputed king.

Australia comes in at number eight, with about 25,760 kilometers. And the UK? It’s not even close to the top ten, despite being an island. Size matters less than shape—a lesson for life, honestly.

Wait—what about the “inland” issue?

Here’s where it gets slightly controversial. Does Canada’s coastline include all those little islands up north? Yes, according to the CIA World Factbook (yes, spy agencies track this stuff). The measurement counts every island’s shoreline.

If you only count the mainland coastline, Canada would lose to Indonesia. But the world agrees: every square inch of land counts. So, Canada wins fair and square. Take that, geography nerds.

Also, fun side note: Monaco has the shortest coastline—just 5.6 kilometers. You could walk the entire country’s beachfront before finishing your morning baguette. Canada’s coast is 36,000 times longer. Talk about existential scale.

Why does this matter? (Spoiler: it’s about more than bragging)

Having a long coastline is not just trivia—it shapes a country’s identity, economy, and climate. Canada has the largest marine territory on Earth, controlling rich fishing grounds and shipping routes.

It also means massive challenges: protecting shorelines from erosion, oil spills, and climate change. Melting Arctic ice is opening new waters, but also threatening Indigenous communities who’ve lived along these coasts for millennia.

And let’s be real—if you’re a Canadian, you probably haven’t seen most of your own coastline. I mean, who has time to visit 200,000 kilometers of beaches? That’s a lifetime road trip.

Final thought: next time you’re on a beach, tip your hat to Canada

So, if you ever find yourself arguing over a pub quiz, remember: Canada wears the crown. Not because of maple syrup, polite people, or hockey—but because geography decided to make its edges ridiculously crinkly.

And if someone tries to tell you it’s Australia or Russia? Just smile, take a sip of your drink, and say, “Fractals, my friend. It’s all about the fractals.” Then watch them Google it like I did after that Portuguese seagull incident.
