Very useful

Radius around a town or a point would be very useful - trying to use this to find a new home in an area, and we don't know postcodes for the centre points.

Colin, please have a look at How Far Can I Travel. It does something very close to this on a worldwide basis.

Thanks for such a useful tool. To take it to another level, how about the option of plotting a line of constant distance traveled along roads, so it would be an irregular shape rather than a circle. It's a tall order, I know...

Hi, you can switch to full screen and take a screenshot.

How do I get a copy of plotted map radius
By admin@camoskips.co.uk on 13/04/2016

Please show/list all postcodes that fall within the boundaries selected.

I would like to use this map for my website. How can I transfer it? What is the cost? Thanks Susan

Hi This tool is wonderful. Using it to help people visualise how easily short distances could be cycled I would find it eve more useful if the Google bicycling layer could be overlaid.

Thank you. Very useful for users of electric cars. Point to remember is radius is as the crow flies not actual milage by road.

Thanks Brian

Needed to find areas within 100 miles of my home for business use. It worked a treat, great site, many thanks

Can I highlight 10kms along the entire length of a UK county border?
By Steven on 17/02/2016

Completely useless!

Hi Paul, unfortunately this is not possible.
By Free Map Tools on 22/01/2016

Hi there Is there a way to restrict the population values returned to one country. For example, if I am searching for a population within 100 miles of a UK postcode I only want to see UK population
By Paul on 22/01/2016

Hi Susan, sorry this is not possible.
