Antipode Finder - Opposite Side of the World
Example: Madrid → Wellington, NZ
Where would you end up if you dug straight through the center of the Earth? This antipode finder shows the point on the opposite side of the world. Your antipode is the spot on Earth's surface diametrically opposite your location. Enter a city or your coordinates to find your antipodal point and the nearest major city. Because oceans cover most of the planet, most antipodes are in the water.

How We Calculate This
Antipodal latitude = -input latitude. Antipodal longitude = input longitude + 180 (normalized to -180 to 180 range). Distance to nearest city uses the Haversine formula for great-circle distance.

Frequently Asked Questions
What is an antipode?
An antipode (or antipodal point) is the point on Earth's surface diametrically opposite to a given location. It's where you'd emerge if you tunneled straight through Earth's center.
How is the antipode calculated?
The math is simple: antipodal latitude = -original latitude, antipodal longitude = original longitude ± 180°. If the result exceeds ±180°, it wraps around.
Why do most antipodes fall in the ocean?
About 71% of Earth's surface is ocean. Most of the populated Northern Hemisphere's antipodes are in the vast Pacific or Indian Oceans. Only about 4% of land has a land antipode.
What is an "Earth sandwich"?
An Earth sandwich is when two people on opposite sides of the world simultaneously place bread on the ground, creating a "sandwich" with Earth as the filling. It's a fun geography challenge!
Which cities have land antipodes?
Very few! Madrid and Wellington, NZ are a famous pair. Parts of China (Shanghai, Hong Kong, Taipei) have antipodes in Argentina/Paraguay. Most major cities have their antipode in the ocean.
