Slide to any meridian and see every country it passes through.
How this tool works
Pick any longitude and the tool intersects that meridian with all country boundaries live in your browser, listing countries crossed with approximate overland lengths and drawing the line pole to pole. Unlike latitude circles, every meridian is the same length, about 40,008 km around.
What you can do with it
- Find which countries line up north to south anywhere on Earth
- Check which meridian your city sits on and who shares it
- Explore historically important meridians beyond Greenwich
- Compare how empty the Pacific meridians are versus Europe and Africa
Why use it
Meridians reveal surprising alignments: which countries sit directly north or south of each other is one of the most reliably counterintuitive geography questions there is.
