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.
Radius Around Point Map
- Type in a radius required in the text box above.
- [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].
- Click as many times as necessary to draw multiple circles.
- 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:
- Draw one or more radii on the map as you see fit
- Once ready, click the [Generate KML] button. You will probably need to scroll down the page to find this!
- After a short delay, a blue hyperlink will appear below the button that reads [Download KML File Here]
- Click the hyperlink to download the KML file to your local machine
- You can then open the KML file in application such as Google Earth
Currently, the KML will include:
- The same radius size and shape
- Transparency of 50%
It will not include:
- Shading colour (blue only, but you can change this once it is loaded into Google Earth)
- Line colour (you can change this once it is loaded into Google Earth)
- Line thickness (you can change this once it is loaded into Google Earth)
These features may be added later depending on feedback.
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.

I'd really like to be able to easitly print the circle to a PDF or printer or save as a JPG. I can do it, but it's a bit cumbersome.

It uses air miles.
By Free Map Tools on 26/08/2015
Is the radius made up of road miles or air/nautical miles?
By Sam on 24/08/2015
Can you include a printout of the zipcode at the center of each circle that is placed? It would help me as I'm job searching to input job search parameters of geographic locations.
By Mike on 24/08/2015
Exactly what I needed! :)
Mike, you can find out the population inside the radius by using the User Menu. Please see our blog article for more details.
By Free Map Tools on 18/08/2015
it would be cool to add statistics like total population in/outside of radius etc. But this is still very cool, thanks!

Hi Sharon, please use [Birmingham, UK] and this should do the trick.
By Free Map Tools on 14/08/2015
Hi, I'm trying to add Birmingham UK, but every time I try any address/postcode (zip), it takes me to Birmingham Alabama!

Hi Jo, perhaps Draw Concentric Circles can help do what you require?
By Free Map Tools on 11/08/2015
Any chance from the same location I can put two or three radius dimensions. eg 15km, 25km and 50km, so I can create freight like quote distances from depot?
By Jo on 11/08/2015
Hey guys, anyone else using this with Tinder? :))

Great tool! Thank you!
And I agree, it would be nice to see the city names that are within a radius.
It appears if you expand the Map Options section

where is the CLEAR MAP button?
Hi Fiona, you can use print screen or the snipping tool to take a screenshot of the map and then print. You can also save a radius for future by using the User Menu at the top right of this page.
By Free Map Tools on 26/07/2015
How can I save my radius map to a document and print it?
By Fiona on 24/07/2015
good one....very useful....thank you for all your team who worked for this tool.
