Radius Around Point

You can use this tool to find the radius around a point on the map. First type in the radius required in kilometers or miles and then click on the map at the center of where you wish the circle to appear. You can then create as many radii as you wish.

Add label marker: Type text below then click on the marker for which the label should be attached:


Circumference of last circle km miles
Area of last circle km² acres

Once you have a radius on the map :

 Generate KML 

CSV Upload - [latitude,longitude,radius(km),label(1 text character / optional)] per line

Click Here to Show/Hide CSV Upload Panel


  1. Type in a radius required in the text box above.
  2. [Zoom and Pan to find the required area on the map then click on the map to draw a circle] OR [Type a location into the text box and click Draw Radius] OR [Input the latitude and longitude of the location in decimal format].
  3. Click as many times as necessary to draw multiple circles.
  4. You can use the [Clear Map] button to erase all markers and radii and start again.

Use the "URL to last radius" text box to find a URL that will show the most recent radius on this page when opened in a web browser. This URL can be sent to anyone if you wish to forward it on.

Google Earth KML Output

You can now export all the drawn radii on the map to Google Earth for improved display and printing. You must have Google Earth installed (or another application capable of importing KML files). You need to have a radius displayed on the map before the output will work. Please report any bugs.

The procedure to Export to KML is as follows:

  1. Draw one or more radii on the map as you see fit
  2. Once ready, click the [Generate KML] button. You will probably need to scroll down the page to find this!
  3. After a short delay, a blue hyperlink will appear below the button that reads [Download KML File Here]
  4. Click the hyperlink to download the KML file to your local machine
  5. You can then open the KML file in application such as Google Earth

Currently, the KML will include:

  1. The same radius size and shape
  2. Transparency of 50%

It will not include:

  1. Shading colour (blue only, but you can change this once it is loaded into Google Earth)
  2. Line colour (you can change this once it is loaded into Google Earth)
  3. Line thickness (you can change this once it is loaded into Google Earth)

These features may be added later depending on feedback.

CSV Upload

The CSV option allows you to upload bulk points to the map. To do this you must format your points using the convention of latitude,longitude,radius per line where latitude and longitude are in decimal format and radius in km. Make sure to strip out any whitespace. You can upload as many lines as you wish, however more lines will take more time and every web browser will have its limits on the maximum number of lines (hence circles drawn) before things slow to a halt.

For Example...


..should add two radii around the Olympic stadium in London for 10km and 15km

Future Ideas

  • To be able to download the list of circles parameters, in the same way as the CSV upload
  • Ability to input nautical miles

ryq, you can clear the data using the Clear map button inside the map options section. If the point plotted isn't accurate to the location you expect, it helps to specify the state/county/country as well as this is intended to be used worldwide and some town or city names are ambiguous in this context. In terms of "decides its own numbers" please explain and we will be glad to look in to this.

On a scale of 1-10, I give it a 1. It doesn't clear data, decides to post centers in other states, decides its own numbers. Hey, it's a random circle generator.

fantastic free tool!

please find my radius abouve
By ANDREJ KURDIUMOV on 14th August 2016

Jessica , the only option currently is to use the [CSV Upload] section and add a 1 letter annotation
By Free Map Tools on 11th August 2016

How can I caption my radii?
By Jessica on 11th August 2016

Hi Frank, if you expand [Map Options] the Clear Map button should be in there. This is reset the map.
By Free Map Tools on 11th August 2016

How about a "Clear Searches" button?
By Frank on 11th August 2016

extramsg, can you provide the address used please and we will investigate.
By Free Map Tools on 5th August 2016

Sucks. Gets the original address right, but screws up the lat/long when it draws the circle, resulting in an incorrect result.
By extramsg on 4th August 2016

Thank you. My mother got a 500yd protection order from her ex. Her Ex just moved and we started thinking that his new place is really close. I used your mapping tool to find out that indeed he is 256yrds away. I know it's now what the tool was meant for, but it's really helped her in her abuse case against him.
By BM on 31st July 2016

SP, thanks for the feedback. These options are hidden until you click the [Map Options] section. You should then see options Clear Map and Full Screen.
By Free Map Tools on 29th July 2016

Great site. I would like to suggest a reset button as the only way to clear the map was to refresh the page after I accidentally added a radius point. Also if you could add a button to maximize just the map window it would make analysis easier instead of being constrained to the current window size.
By SP on 28th July 2016

Hi, if you expand [Map Options] the Clear Map button should be in there.
By Free Map Tools on 21st July 2016

I don't see a "clear Map" button -- it is talked about but I don't see one.
On 21st July 2016

Androish, this new feature has now been added.
By Free Map Tools on 21st July 2016

Andrew, multiple radius in the URL has now been added
By Free Map Tools on 21st July 2016

thanks, i got compliment from my boss
