Multi-ring radius map generator
This radius map tool draws distance rings around any point on an interactive map. Place a center by clicking the map, searching an address or using your current location, then set the ring spacing, ring count and total radius — at city, regional or global scale, in miles or kilometers.
Rings can be styled with your own line and fill colors, opacity, line width and solid or dashed lines, on light, dark, street, outdoor, satellite or blank basemaps. Gap, count and total radius stay linked, so you can think in "rings every mile" or "out to 25 km" and the other values follow.
Common uses include delivery zone planning, emergency response coverage, store catchment analysis, travel distance visualization, event planning, and comparing coverage between several locations.
How to draw a radius on a map
- Search for an address or place, click the map, or tap My location to set the center.
- Choose miles or km.
- For evenly spaced rings, set the gap and the number of rings — or type the total radius. For uneven rings, switch to Custom and list the distances, such as
1, 3, 5, 10. - To compare several locations, switch Click map to to Add center and place each one; they all share the same rings.
- Adjust colors and labels, then copy a link to share the map.
Examples
- 5 mile radius: miles, Equal, gap 5, count 1.
- Rings every mile out to 3 miles: miles, Equal, gap 1, count 3.
- Walk, bike and drive zones: km, Custom,
1, 5, 20. - Flight range from a city: km, Global scale, gap 1000, count 5.
How accurate are the circles?
Every ring is a geodesic circle: each point on it is the stated distance from the center along the Earth's surface, so a 1,000 km ring is right even across countries. Because web maps use the Mercator projection, which stretches shapes toward the poles, large rings and rings far from the equator look oval on screen even though the distances are correct. Ring areas are calculated on the globe, not on the flat map.
A radius shows straight-line distance. Rivers, highways and terrain mean real travel distance is longer; for drive or walk times, use an isochrone map instead.
Frequently asked questions
How do I draw a 5 mile radius on a map?
Choose miles, set Equal rings with a gap of 5 and a count of 1, then click the map or search an address to place the center. For rings every mile up to 5 miles, use a gap of 1 and a count of 5.
Can I draw circles around several addresses?
Yes. Switch "Click map to" to Add center, then click or search each location. Every center gets the same set of rings, and each one can be dragged, renamed or removed.
Why does my circle look like an oval?
Circles are drawn on the curved Earth, so every point of a ring is the true distance from the center. Web maps use the Mercator projection, which stretches shapes away from the equator, so large or far-north circles look taller than they are wide.
Can I share my radius map?
Yes. Copy link saves your centers and ring settings into the link, so anyone who opens it sees the same rings.
