Yes. Use decimal degrees in the format latitude, longitude (for example: 40.4168, -3.7038), or enter values in the coordinate tool below. Latitude must stay between -90 and 90, and longitude between -180 and 180 for valid results.
Can I choose a point directly on the map?
Yes. Click anywhere on the left map to set your origin point. The antipode marker and all related calculations update instantly, including biggest city in radius and population totals.
What does "Biggest city in radius" mean?
It finds the city with the highest population inside your selected radius around the antipode. Results come from the built-in cities15000 dataset. Increase the radius to include a wider area, or decrease it to focus on local context around the exact antipode point.
Which cities are included in City Insights?
City Insights uses the cities15000 dataset, so it includes cities and populated places with population above 15,000. Smaller towns and villages are not part of these radius calculations.
Why do I sometimes get "No city found in this radius"?
Some antipodes are remote and far from major settlements. Increase the radius slider to capture more cities from the dataset, especially when the antipode lies in oceanic or sparsely populated regions. Also note that only places above 15,000 population are included.
Can I calculate distance between two points?
Yes. The distance tool below the map returns great-circle distance (shortest path over Earth’s surface) in kilometers. This is useful for aviation-style route context and global comparisons, even when no direct road route exists.
How precise are antipode coordinates and distances?
Antipodes are computed mathematically from your input coordinates. Distance values use spherical Earth formulas and are accurate for practical planning and education, with small differences possible versus ellipsoidal geodesic models.
Can I share a result link?
Yes. The URL updates with your query parameter after search, so you can copy the page link and share that exact lookup. Anyone opening the link will load the same place input directly.
Antipode quick facts
Use these quick facts to understand what antipodes mean in real-world geography.
Most antipodes are in the ocean
Land covers less than a third of Earth, so the opposite point is usually water. On an antipode map, many searches point to the Pacific or Southern Ocean. Use an antipode calculator to confirm whether the opposite side of Earth is sea or land for any coordinates.
Land-to-land pairs are uncommon
Exact city-to-city antipodes are rare. That is why antipode lookup tools usually show nearest major cities instead of perfect urban matches. Nearby-city context around antipode coordinates is more useful for practical geography and travel comparisons.
Near-maximum surface distance
Antipodes are about 20,000 km apart along the surface (roughly half Earth's circumference). This is close to the longest possible great-circle distance between two places on Earth. It makes antipode distance a useful benchmark when comparing global routes.
Opposite hemispheres
North becomes south, so seasons are generally reversed between antipodes. When you find the opposite side of Earth, weather and daylight trends are often inverted by month. This helps when comparing climate zones between your origin and antipode location.
Why "digging to China" is usually wrong
From most of North America and Europe, the antipode lands in the ocean, not East Asia. An antipode map debunks this myth quickly by plotting true opposite coordinates. Try different major cities to see how often the endpoint is open water.
Time is not always 12 hours apart
Time zones follow borders, so antipodes do not guarantee a clean 12-hour clock difference. Political boundaries and daylight-saving rules can shift offsets away from a perfect 12 hours. Check both antipode coordinates and local time data for accurate comparisons.
