Let’s wrap this up like a burrito. The Mexico-U.S. border is about 1,954 miles. That’s longer than the distance between Berlin and Baghdad, but shorter than the Great Wall of China (which is 13,171 miles, if you’re keeping score). Compared to the U.S.-Canada border? That one is 5,525 miles—the longest international border in the world. So, Mexico? It’s the little brother of borders. But it’s the one everyone talks about, because drama sells.
So next time someone asks, “How long is the Mexico-US border?” you can say, “It depends on whether you’re measuring with a ruler, a river, or a lawsuit.” Then, for extra credit, tell them the Rio Grande is actually the Rio Grande—Spanish for “Big River.” It’s not. It’s, like, medium. But hey, it’s the thought that counts. Now, go measure something else, like your coffee mug. I bet it’s shorter than you think.
