Frequently Asked Questions

What is straight-line distance?

Also called "as the crow flies" distance, it's the shortest path between two points on Earth's surface, calculated using the Haversine formula. It ignores roads, terrain, and flight paths.

How is the flight time estimated?

Flight times are estimated using an average commercial jet speed of 850 km/h, plus 30 minutes for takeoff and landing. Actual flight times vary based on route, wind, and layovers.

Can I compare city sizes too?

Yes! Each distance page links to the corresponding city size comparison, where you can see both cities side by side on synchronized maps at the same zoom level.
