Distance Calculator

You can use this distance calculator to find out the distance between two or more points anywhere on the earth. In other words, the distance between A and B. Click once on the map to place the first marker and then click again to position the second marker. The distance between the points will then be displayed. You can also build up a series of locations to find a total distance.

[Map Height : Small - Medium - Large]

An important feature of this distance calculator tool is that it is "as the crow flies", so traveling in real life will normally involve larger distances, but this may also help those who need to measure off-road distances.

How To Use

  1. Zoom and drag the map to find the location of marker 1
  2. Click to place marker 1.
  3. Zoom and drag the map to find the location of marker 2.
  4. Click to place marker 2.
  5. The distance will be calculated then displayed below the map in miles or kilometers. You can change between miles or km at any time
  6. Add as many points as required and the distance will build up.
  7. You can also drag and drop markers after they have been put on the map
  8. To share your route and distance calculation use the option [Generate Link For This Route]. You can then copy the link generated and send this via Twitter or Facebook.


All distances are estimations so Daft Logic does not accept any responsibility that may arise when the value reported is incorrect.

You can move the markers after they have been positioned so you can modify you route on the fly and see how the distance will be affected.


  • Click [Clear Last] to undo the last marker placed
  • Click [Zoom To Fit] to zoom the map around all markers
  • Click [Clear Map] to erase all markers and start again
  • Use the Quick Find text box to quickly relocate the map
  • You can choose between miles and kilometers (km) for the Total Distance readout
  • Click [Show Elevation] to get a chart showing the elevation of your route

How it Works

Clearly you, the user inputs two 'points' that are used to calculate the distance. Calculating the "As the Crow Flies" distance is a matter of using Great Circle formula. Then the main problem is converting the Google Map unit to miles and kilometers.

The map will also automatically save your route in your temporary internet cookies so that you can return and see the route as you last left it. If you ever need to start from scratch then use the [Clear Map] button.

Benchmark Tests

Mary Peters Track in Belfast

Map showing the Mary Peters Track in South Belfast. The reading shows 0.394km which is clearly a reasonable measurement for an athletics track.

Map between New York and Paris

Map showing the estimated distance between New York and Paris. All references that can be found suggest that this is an accurate measurement.

Seven Mile Straight in Antrim

Map showing the Seven Mile Straight in County Antrim, Northern Ireland. This shows a reading of 6.910 miles.

Map between Belfast and Dublin

Map showing the distance between Belfast and Dublin. As far as I can see this is an accurate estimate (if there is such a thing). This trip would be approximately 100 miles by road so the proverbial crow would have less distance to travel.

How can I use this tool in my website to claculate distance??

The change making us hold CTL while scrolling in/out kind of sucks. Please remove it.

Google Maps will report land (by car) miles.
By Daft Logic on 26th April 2017
Hi John, yes it is still alive!
By Daft Logic on 26th April 2017
Odd question, but let me ask. Using Google Maps going from point A to point B, it says it is 25 miles. My question.....is this considered Land Miles or Aerial Miles. If it is 25 land miles, I need to get to how many aerial miles by multiply 25 by .868 which is 19 aerial miles. So, is Google Maps Land of Aerial miles?
On 25th April 2017
Is this blog still alive?. Have question, but will hold till I see its still working.
By John on 25th April 2017
Excelente herramienta de trabajo y de consulta... thanks very much.
By Jose Uriel Sanchez on 20th April 2017
There used to be buttons attached to the zoom function that allowed for shifting the map a fixed distance in any direction. Any hope to bring that back?
By Asdrubal on 13th April 2017
It's not possible to switch to feet on the elevation output.
By Daft Logic on 5th April 2017
Any way to change the elevations from metric to feet?

Great job on this project!

This distance calculator differs from google maps greatly and is annoying
On 15th March 2017
fantastic tool. God bless u guys for giving it for free usage. I am not a programmer but a logical guy. I will be happy to help if I can be of any use.
By Rajat Gupta on 26th February 2017
You can use the Google Maps Area Calculator Tool.
By Daft Logic on 24th February 2017
Can i work out the area on this ?
On 24th February 2017
Martin, you can now upload GPX files as found on www.walkhighlands.co.uk
By Daft Logic on 23rd February 2017
Very very useful application. Thank you so much and good luck.
By Faryabi, Kerman on 23rd February 2017
There are many other distance calculator sites, and many other versions of me. Yet every single time I choose daftlogic's project? This isn't fate, this is true love. KEEP IT UP!

I like this
On 4th February 2017
Dear Sir, I thank you for your prompt action!
By Mr. Alkis, Athens Greece on 30th January 2017
Mr. Alkis, thanks for the feedback. It now shows that lat/lng just as before as well as the distance.
By Daft Logic on 27th January 2017
Hi, I like the new feature where hovering over a marker shows the distance, but I really miss the display of LAT LONG for the point which we had up until 5.14 .. Can't we have both?
By Mr. Alkis, Athens Greece on 26th January 2017
Hi, you can measure areas here : Google Maps Area Calculator Tool.
By Daft Logic on 23rd January 2017
I see that you are considering further ideas.
What about calculate surfaces ? ( I mean the surface contained within a closed perimeter.)
Then the application would be STELLAR!

By Claudio from TRIEST on 19th January 2017
Mr. Dave - A change has been implemented so that the marker will display the distance up to that leg on the route when you hover over it.
By Daft Logic on 10th January 2017
This is a wonderful and very useful application (or how to call it?).
Mille merci!
