Radius Map
Drop a center (your location, a click, or a search) and draw a circle of any radius in kilometres or miles. The tool shows the circle live on the map, its area, and every city from our world database that falls inside — handy for delivery zones, travel planning, and "what's within 100 km of me" questions.

What people draw radii for
- Business zones: delivery ranges, service areas, catchment estimates.
- Travel: "what can I reach within 300 km" — the in-circle city list links straight to each city's coordinates page.
- Regulations & filters: visualising distance-based rules (residency radii, drone limits, listing filters).
- Curiosity: a 20,000 km radius covers the whole planet — try it.
The circle is drawn geodesically-honest for its size: distances are computed on the sphere, so the city list stays correct even for huge radii where flat-map circles lie.
Frequently asked questions
Can I draw the radius in miles?
Yes — switch the unit toggle and both the input and the readout flip between kilometres and miles (the circle itself is identical).
Which cities are listed inside the circle?
The 300+ world cities and landmarks from this site's coordinates database that fall within your radius, sorted by distance — each links to its full coordinates page.
Is the circle accurate for huge radii?
Distances are computed on the sphere, so the in-circle list is correct at any size. The drawn circle uses the map projection, which visually stretches near the poles — the list is the truth.
