About CityDistance.io

What is CityDistance.io?

CityDistance.io is a free online tool that helps you find cities based on their distances from known locations. Using the principle of triangulation, you can pinpoint cities by entering the distances from two or three reference cities.

How It Works

Our triangulation calculator works by drawing distance circles around your reference cities. Where these circles intersect, you'll find cities that match your distance criteria. The more reference cities you use, the more accurate your results will be.

• 2 Cities: Creates two intersecting circles, typically giving two possible intersection areas
• 3 Cities: More precise triangulation with a single intersection point

Use Cases

• Solving geography games and puzzles (like GeoGuessr, Worldle)
• Educational purposes - learning about geography and distances
• Travel planning - finding cities at specific distances
• Curiosity - exploring what cities are equidistant from multiple locations

Data Sources

Our city database contains over 30,000 cities worldwide, sourced from GeoNames. Map data is provided by OpenStreetMap contributors.
