Antipode Map and Opposite Point Finder
Find the exact antipode—the point on the opposite side of the Earth if you dug a straight line through the center of the globe—for your current GPS location, any U.S. city or ZIP Code, or any latitude/longitude coordinates.
Use your current location, enter a city, ZIP Code, or coordinates, or pick a sample point above.

How Antipodes Are Calculated and Mapped
An antipode is the point on Earth’s surface that sits diametrically opposite to your starting location—the exact spot you would emerge if you drilled a straight tunnel directly through the center of the planet. Mathematically, for any WGS84 latitude φ and longitude λ, the antipodal latitude is the opposite hemisphere at the same angle (φ′ = −φ) and the antipodal longitude is shifted by 180 degrees around the globe (λ′ = λ + 180° when λ ≤ 0°, or λ′ = λ − 180° when λ > 0°). The surface great-circle distance between any point and its antipode is half the circumference of the Earth: approximately 12,430 miles (20,004 kilometers) in every compass direction.
Why Almost Every U.S. Antipode Falls in the Indian Ocean
Because ocean water covers roughly 71% of the Earth’s surface and two-thirds of all continental landmass sits in the Northern Hemisphere, only about 15% of land area on Earth has an antipode that also lands on solid ground (roughly 4% of the planet’s total surface area):
- Contiguous United States (Lower 48): Nearly the entire mainland United States (
25°N–49°N,67°W–125°W) is antipodal to the remote southern Indian Ocean between Madagascar, Western Australia, and Antarctica (25°S–49°S,55°E–113°E). - Rare U.S. Land Antipodes: The Hawaiian Islands (
19°N–22°N,155°W–160°W) are antipodal to land in southern Africa—specifically Botswana and Namibia—while a few towns in northern Montana near the Canadian border (such as Havre and Rudyard, Montana) are antipodal to the French Southern and Antarctic Lands (Kerguelen Islands). - Major Global Land Antipode Pairs: Spain and Portugal are antipodal to New Zealand; Chile and Argentina are antipodal to eastern China and Mongolia; and parts of Southeast Asia are antipodal to the Amazon Basin in South America.
Instant Land vs. Ocean Detection
Whenever you calculate an antipode on QuickWhere, our browser engine tests the opposite coordinates against 242 countries and territories in the Natural Earth 1:50m boundary dataset to tell you immediately whether your opposite point hits land or open ocean, and plots both pins on the world map.
