About City Distance

What is City Distance?

City Distance 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.

We built CityDistance.io as a practical geography utility first. The site combines interactive calculators, reference pages, and educational articles so users can both solve a distance problem quickly and understand the geographic logic behind the answer.

Who We Build For

City Distance is designed for people who need fast, trustworthy distance context between world cities without opening a complicated GIS tool or jumping across multiple travel sites.

• Players of geography games who need to reason from distance clues, radius clues, or triangulation hints
• Students and teachers looking for approachable examples of great-circle distance and global scale
• Travel-curious readers who want to compare routes, flight distance, and regional geography
• General users who simply want a clean city-to-city distance lookup with map context

How to Use

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 SatZoom, Satle)
• Educational purposes - learning about geography and distances
• Travel planning - finding cities at specific distances
• Curiosity - exploring what cities are equidistant from multiple locations

What You Can Do on CityDistance

Beyond the triangulation solver, CityDistance offers a suite of geography tools and content pages:

• Use the city-to-city distance calculator for any two cities worldwide, or the radius search to find every city within a given distance.
• Read practical guides in the City Distance Blog, including distance estimation, radius clues, and triangulation strategy.
• Use the built-in city search database inside the calculators to look up major cities worldwide without leaving the tool workflow.
• Train your geography intuition with three free quiz modes: the Daily Challenge, Distance Guess sprint, and the City Distance Quiz.
• Read the City Distance Blog for tutorials on triangulation, distance estimation, great-circle routes, and common geography-game mistakes.

How Our Distance Calculations Work

City Distance focuses on straight-line geographic distance, also called great-circle distance. For most tools on the site, we calculate the shortest path over the Earth's surface using city latitude and longitude coordinates. This is the standard way to compare global city scale and to support geography games that use coordinate-based distance clues.

In practical terms, this means our results are designed for geographic comparison, not for turn-by-turn driving routes. Where we show estimated flight times, those are supporting reference values derived from distance and typical air-travel assumptions rather than live airline schedules.

Data Sources

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

We use that raw geographic foundation to build search, triangulation, reference pages, and educational content around a curated set of major cities and notable city pairs.

Editorial Standards

We do not treat City Distance as a pure page farm. Our goal is to publish pages that are useful on their own, explain how a result should be interpreted, and help users build better geographic intuition over time.

• We write original guides and explainers around the tools instead of relying only on generated route templates
• We review copy for clarity, consistency, and whether it actually helps a user answer a geography question
• We keep legal, privacy, and contact information publicly available so users know who operates the site
• We continue refining which pages are indexable so search traffic lands on pages with stronger standalone value

Updates and Feedback

City Distance is updated continuously. We expand content, improve route explanations, adjust page quality thresholds, and add new educational articles as the site grows.

If you spot a data issue, want a specific topic covered in the blog, or have feedback on a tool or city page, email us at info@citydistance.io. Reader feedback helps us decide which improvements should be prioritized next.
