Draw a radius around any point on a map
The radius map tool draws true distance circles around any location on Earth. Set a center by searching for an address or city, clicking the map, or dragging the pin — then enter a radius in kilometers, miles, or nautical miles. It's the fastest way to answer questions like "what's within 30 km of here?" or "how far does a 5-mile delivery zone reach?".
Unlike simple screen-space circles, every ring here is a geodesic circle computed on the Earth's surface, so the distance is exact in every direction at any latitude. Add up to five color-coded rings to compare zones — service areas, commute ranges, drone flight limits, school catchments — and export the result as a clean high-resolution PNG.
Frequently asked questions
How do I draw a radius on a map?
Search for a place or click anywhere on the map to set a center point, then type a radius in kilometers, miles, or nautical miles. The circle updates instantly and you can drag the pin to fine-tune the center.
Are the circles geographically accurate?
Yes. Each ring is computed as a geodesic circle on the Earth's surface, so a 100 km radius is a true 100 km in every direction — even at high latitudes where flat-map circles become distorted.
Can I draw multiple radius rings at once?
Yes, you can add up to five rings around the same center — useful for delivery zones, commute ranges, or coverage tiers. Each ring gets its own color and shows its area.
Is the radius map tool free?
Completely free, with no account required. You can download your radius map as a high-resolution PNG image and use it in documents, presentations, or listings.
