Drawing Concentric Circles on a Map

If you have a need to produce a map with a range of circles to indicate a series of radius from a central point, our Concentric Circles Map can be used.

This can be useful when it comes to estimating delivery zones or delivery charges for fast food delivery series for example.

In order to use the Concentric Circles Map, it is necessary to add lines of text with a particular format to the text box below the map. We will now show a few examples of how this can be done:

First, you need to browse to the page http://www.freemaptools.com/concentric-circles.htm

The format of each line is:

[Location] , [Start Radius] , [End Radius] , [Colour]


  • [Location] is the location of the centre point inside a pair of double quotes. This can be a place name or a latitude / longitude value
  • [Start Radius] – The radius where this concentric circle starts
  • [End Radius] – The radius where this concentric circle ends
  • [Colour] – The fill colour of the radius.

You can add one or many lines depending on how many concentric circles you require. We will now show a few examples of how this can be used.

Example 1: Delivery Zones in London

If we wish to express 4 delivery zones in London, England, each 5km apart, we can use the lines:

“London, England”,0,5,Blue

“London, England”,5,10,Green

“London, England”,10,15,Orange

“London, England”,15,20,Red



Lines used for Delivery Zones in London

This will produce the following Concentric Circle Map:


Delivery Zones in London

Example 2: 100 mile to 150mile Range From New York

If we wish to illustrate an area between a 100 and 150 miles radius from New York with latitude/longitude of 40.7127, -74.0059 in purple, we could use the following line:

“40.7127, -74.0059”,100,150,purple



Text for 100 mile to 150mile Range From New York

Note: You can specify the units on the map. You can also use the Full Screen button to show the map in full screen mode.

This will produce the following map:


100 to 150 miles radius from New York

List USA ZIP Codes Within a Drive Time Radius

Following the addition of our new User Menu feature, we can show an example of how to use multiple pages on Free Map Tools and share data between them.

This scenario, is to list the USA ZIP codes within a ‘drive time’ radius. In this example we will find all ZIP codes within a 2 hour drive from Detroit, USA.


      1. Make your drive time radius. E.g. https://www.freemaptools.com/how-far-can-i-travel.htm?address=Detroit,%20Michigan,%20USA&speed=53&time=2&accuracy=10&u=km&hw=false&m=false&mode=DRIVING
      2. Once finished, choose Save Area from the User Menu
      3. Give the new area a name
        User Menu Save Area
      4. Go to http://www.freemaptools.com/find-zip-codes-inside-user-defined-area.htm
      5. Choose User Menu > Load Area
      6. Click your new area from the list to load it
      7. Click the Search For ZIP codes button

Your ZIPs are now returned!

Please use this example a basis for your own needs and uses across different pages on Free Map Tools

You can see how data is compatible between pages on https://www.freemaptools.com/about-user-menu.htm#featuretable
