Radius Map — Draw a Circle Around Any Address
Free radius map tool with no signup and no usage limits. Search an address (or use your location), drop a circle in miles or kilometers, add more circles, then share the link or export a PNG / KML file. Everything runs in your browser.

Click the map to drop a circle · drag the white center dot to move · drag the outlined edge dot to resize · up to 12 circles.
How to draw a radius on a map
- Find your center. Type an address or place into the search box, tap the map directly, or press My location to center on where you are right now.
- Set the radius. Enter a number with your preferred unit — miles, kilometers, meters or feet — or use the one-tap presets for 1, 5, 10, 25, 50 and 100 miles.
- Fine-tune. Drag the white center dot to move a circle, and drag the outlined dot on its edge to resize. The label always shows the current radius.
- Save or share. Copy link encodes every circle into the URL, PNG downloads a snapshot image, and KML gives you a file you can open in Google Earth or import into Google My Maps.
What is a radius map used for?
Real estate. Show buyers what sits inside a 5, 10 or 20 mile ring around a listing — schools, grocery stores, hospitals and commuter towns. Export the PNG and drop it straight into a listing presentation.
Delivery & service areas. Communicate your delivery radius to customers, check whether an address falls inside your coverage, and share a live map link instead of a screenshot.
Travel & relocation. Answer questions like “what is within 30 miles of this city?” before booking or signing a lease.
Safety & planning. Sketch evacuation radii, noise buffers, event perimeters or emergency response zones for quick, informal planning work.
Radius to area conversion table
Every circle covers a known amount of land. These values assume a perfect circle: area = π × radius².
| Radius (miles) | Area (sq mi) | Area (acres) |
|---|---|---|
| 1 mi | 3.14 | 2,011 |
| 2 mi | 12.57 | 8,043 |
| 3 mi | 28.27 | 18,096 |
| 5 mi | 78.54 | 50,265 |
| 10 mi | 314.16 | 201,062 |
| 15 mi | 706.86 | 452,389 |
| 20 mi | 1,256.64 | 804,248 |
| 25 mi | 1,963.5 | 1,256,637 |
| 50 mi | 7,853.98 | 5,026,548 |

How to draw a radius on Google Maps (the workaround)
Google Maps does not offer a built-in radius tool — the circle drawing options people ask about simply aren't in the consumer app. The practical workaround is to draw your circle here, then export it as a KML file and import that file into Google My Maps. You get your radius overlaid on Google's familiar map, together with any pins and layers you already keep there. If you don't specifically need the Google interface, the map above does the whole job itself — including sharing and PNG export.

Frequently asked questions
›How accurate is the radius circle?
The circle is a true geodesic circle: every point on its edge is exactly the chosen distance from the center, computed on a spherical Earth model. At the scale of typical radius maps (a few miles to a few hundred), any distortion from the map projection is negligible. Remember that a radius is straight-line distance — roads will almost always be longer.
›Can I draw multiple radius circles on one map?
Yes — up to 12 circles at once. Click a new spot on the map to drop another circle, and use the table below the map to review, select or delete any of them. Each circle gets its own color so overlapping zones stay readable.
›Can I export the circle to Google Earth or Google My Maps?
Yes. The KML button downloads a standards-compliant KML 2.2 file containing every circle as a polygon. Google Earth opens it directly, and Google My Maps accepts it as an import.
›Does this radius tool work on mobile?
It is designed mobile-first. Tapping the map drops a circle, the edge handle resizes by touch, and the tool renders fine down to small phone widths.
›Is this really free? What's the catch?
There is no catch: no account, no watermark, no usage cap. The site is funded by display advertising, and your coordinates never leave your browser — only address searches are sent to the geocoding service.
