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
Radius Center Point Choose one of:
1) Use the radius drawing tool on the map
2) Place radius by location name :
3) Input Coordinates : Latitude Longitude (decimal)
4) Draw radius at your location

InputCSV Upload [latitude,longitude,radius(km),label(optional)] per line
|Circumference of last circle km miles
|Area of last circle km² acres
|Latitude / Longitude of center of last circle
|URL to last radius
|Google Maps Static API Image Output
|Step 1 : Get the map above to look as you wish (pan/zoom/radii)
|Step 2 :
|Google Earth KML Output
|Once you have a radius on the 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, the KML file with download
- 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.

Daniel, please see : Find New Zealand Postcodes Inside a Radius.

Do you have a post code radius feature for New Zealand
By Daniel on 14th February 2024
Amazing, Please add export PDF option.

Something seems to have gone wrong with this tool. Drawing concentric circles around Brisbane, Australia within the 10000-14000 km range results in overlapping arcs which bear no relation to any meaningful measurement of distance.

is there a way to download to PDF or similar?

Thanks for still providing this tool, but the new version seriously needs a Language selection menu for place names, or just have English as the default like the old version did.
On 13th December 2023
I just want to say something positive here. I use this tool to check if fences for geofencing overlap, and the fact that I can generate all my circles at once and have them labeled has made this process unbelievably more efficient. Great job, I'm a huge fan of this tool!
On 13th November 2023
Does not work?
On 2nd November 2023
Please revert back to old version, so much more useful.
By FrutLootz on 25th October 2023
I keep coming back hoping this has improved, but it's still garbage

After you switched to OpenStreet Maps, this utility is not very useful.
When you draw circle you never know what the R is. Before you could see R and other data as you draw. It is a mess now.

The radius does scale correctly when you get close to the north and south poles
By Brett on 12th September 2023
Very cool :thumb up:

We used to use this tool to adjust circles on a map, but now we can't dynamically edit the radius and center position of the circles once placed.
By Alexandre Simoneau on 28th August 2023
Totally incorrect radius being shown
requested 4.4 miles More like <1km
On 21st August 2023
Still don't understand the reason for the absolute downgrade
On 21st August 2023
Ughh this is such a downgrade from the old version!! :(
By Troy on 14th August 2023
Akhil, that name is static so cannot be changed.
By Free Map Tools on 19th July 2023
While uplodating layer on Google earth, the circle name changed as "Radius" how should to change this?
