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.

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.

Note

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.

Options

  • 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.

Hello, I am doing a project and I need the uncertainty (relative or absolute) on my mesures. Could you provide it to me ? Or give me an idea of how to find it ?
By Yaya on 29th November 2016
this is a disgrace and it need some updating so we can find our school
On 20th November 2016
Hi Norm, please get in contact to discuss this.
By Daft Logic on 2nd November 2016
Any update on the curvature of earth addition to elevation plot? Thanks
By Norm at Mount Wilson Observato on 2nd November 2016
This is just Awesome...seriously good thinking batman
By Francis on 20th October 2016
Hi Ichan,
There is a full screen option on the Advanced Google Maps Distance Calculator. Just below the map.
By Daft Logic on 16th October 2016
Is there (or will there ever be) a full screen option? Otherwise really nice and usefull. Much better than the similar thing in Google Earth
By Ichan on 15th October 2016
This is a very useful tool. My only very minor niggle is that whilst the intro text says "find out the distance between two or more points anywhere on the earth", this isn't quite true. Only because a lat/long location in the ocean cannot be searched for and selected via text input ("Not Found" is the feedback). I dare say a later drag-n-drop would allow the marker to be moved but I can't be certain it is exactly where I want it to be!
By Phil W-S on 14th October 2016
An invaluable tool. Too bad Google took it out. 2D & measurement with easy to use interface. 5/5 Thank you!
On 27th September 2016
Thanks Richard
By Daft Logic on 26th September 2016
What a tremendous program!
I now know how much electric fence I need
But a nerdy comment, in your Note should it be affected (verb) not effected? But looking this up does show some discussion
By Richard Rowe on 26th September 2016
Hi Vince, Not sure about this one. Can you try a different browser and see if there is a difference?
By Daft Logic on 22nd September 2016
When going to street view and using full screen as soon as I click full screen mode it cuts screen in half and shows only half of a full screen. just started having this issue today and use this daily. Any suggestions
By Vince on 22nd September 2016
Thanks a lot! I can calculate all my routes for running..
By H on 18th September 2016
Thank you, thank you!!! I can calculate my running routes down to all turns and small streets! Love your site!
By Jack on 18th September 2016
REZA, do you mean to spin the map itself?
By Daft Logic on 7th September 2016
really what a good services.
is it possible to rotate the picture ?

D.C. thats a fair point. The arrow should be darker now.
By Daft Logic on 4th September 2016
Thx, yes. The drop down arrow to change distance units on my screen is so light gray I can hardly see it. Maybe it's my browser, Safari? If not, you may want to darken the arrow somehow.
By D.C. on 4th September 2016
Simes, what does the text box below the map report? Does it have any value?
By Daft Logic on 1st September 2016
I can make it draw a line but it is not displaying a distance. :-(
By Simes on 1st September 2016
Thanks Dadampriest
By Daft Logic on 31st August 2016
You have a typo. Your text reads "An important feature of this distance calculator tool is that is as the crow flies". It should read; "An important feature of this distance calculator tool is that it is as the crow flies". You need to add an "it" to the sentence.
By Dadampriest on 31st August 2016
Perfetto.
On 25th August 2016
D.C there is a drop down beside the distance output to change the units. This includes distance in feet. Is this would you mean?
By Daft Logic on 25th August 2016
I could swear the distance used to be shown in feet, now it is in miles or kilometers. Any way to show it in feet for convenience and precision?
By D.C. on 23rd August 2016
Thanks Matt
By Daft Logic on 22nd August 2016
Great for planning out and measuring running routes. Thanks for the good work!
By Matt Crawford on 22nd August 2016
very good map
On 17th August 2016
Great help for a fancier like me, I can easily know the exact air distance from the release point to our loft that our pigeons will fly. Thank you
