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.

  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

  • Allow annotation for labeling the radius center point
  • Allow annotation for the radius distance
  • Provide more colours

A time (30mins) & distance (30km) option would be handy from a location, eg, how far can I travel driving for 30mins or how many suburbs are 30Km from my starting point in any direction
By Tony on 31/07/2014

When producing multiple radius it would be great to be able to lock previous radius to prevent unintentional alteration of those already established. Also would be nice to have ability to drag screen when in full screen mode, without unintentionally creating another radius
By Tracy D. on 29/07/2014

It would be nice to have a list of cities as a result from the radius.
By Amo on 29/07/2014

Hi Billy, please have a look at How Far Can I Travel.
By Free Map Tools on 28/07/2014

Hi, there is a Full Screen option inside the Map Options section.
By Free Map Tools on 27/07/2014

Maybe make a function so the map can be full screen so you can see it better.
On 27/07/2014

Pls make the map bigger (on the screen). Great tool otherwise
By David on 26/07/2014

Yes, of course, that's what I say I do, i.e. the following long-ish process: 1) Open separate tab/window with Google, 2) type in: 50 feet in kilometers, 3) select and copy the result, 0.01524, 4) Go back to FMT and paste it into the km box. My (and others') suggestion was to simply have a "feet" box (there's plenty of room for it in the GUI), which could either feed straight to the API, if it accepts that, or to do a quick conversion (feet times 0.0003048) before sending it. This isn't a criticism, I hope you understand - this tool is wonderful! The feet thing is the only pain point for me, but I can live with it if need be. Thanks for posting this and the other great Free Map Tools!
By MontrealPaul on 25/07/2014

I am honestly thrilled!
By Mary / Austria on 25/07/2014

it would be really good if you can have an option to plot a line which show travelling distances - IE 10 minutes driving time from a point...
By Billy on 24/07/2014

how do I find the zip codes for multiple points
By Brian D on 24/07/2014

MontrealPaul, the best option would be convert to km and type the decimal number in the km box. So for example 0.05 for 50m or 0.01524 for 50 feet
By Free Map Tools on 23/07/2014

very good tool, it would be useful to set a default colours and line thickness

This is a great app, one of many on this site! One feature I would very much like to see is the ability to enter radii in meters or (preferably, for me) feet. It's possible that the Google API wouldn't accept these - I don't know - but I know it accepts decimal values, because that's how I enter values of less than a mile or kilometre. Perhaps on your side you could do a quick conversion before forwarding to the API? My "quick kludge" is to enter the feet into Google, and it quickly returns the decimal values of miles/kilometres, but it's clumsy, and it would be good not to have to add this step! Thanks!

Hi David, when we test, it looks fine...Image and video hosting by TinyPic
By Free Map Tools on 21/07/2014

The calculations need to be adjusted. I asked to draw a 60-mile radius around Greenville SC and it drew about a 35-mile radius.
By David on 21/07/2014

Hi Stephen, there isn't too much we can do as this is controlled by the Google Static Maps API.
By Free Map Tools on 14/07/2014

The map image on this page looks fine and the cities are readable through the overlays. When I look at the static map image the city/town names are hard to read because the shading is too dark. Is there a way to lighten that up?
By Stephen on 14/07/2014

MG, The problem isn't the file size as such. It is the length of the request before it makes the file will all the coordinates of every circle. This is hitting a limit. Yes, please split the requests to let it work
By Free Map Tools on 03/07/2014

If i have a 1.25 mile radius what would be my Circumference?
