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.

Comments For This Page

I noticed the same thing as below and some of the Russian roads have propaganda inserted where the street name would go.
On 17th June 2024
Just curious. I've been using Daft Logic weekly, if not more often, for several years. Yesterday, it suddenly overlay roads from elsewhere in the world, probably somewhere in Russia, based on the road names (POCCNR, e.g.). This morning, it further overlaid road names that appear to be British (Rudgate, York). These were visible, criss-crossing the local roads in the Johnson Creek, Wisconsin, vicinity when one zoomed in part-way. Very strange. ???

Very nice, great tool for multiple tasks. Thanks.

Daft Logic maps went from being my "all time favourite map tool" to the "most mediocre of the mediocre"
This is where we part company. Bye

I love this app and please keep it going. It makes plotting out training running distances on old train paths a breeze! much love.
By scrappy runner on 27th January 2024
I've been using this webpage since I found it last 5 yrs ago and it helps me get an accurate distance vs the fare I am paying since most of the public utility vehicle drivers are charging us people excessively. I hope this page wont die
By Mich on 19th November 2023
cannot get location !!!!
On 4th October 2023
Every time I try to do the distance calculator and switch from OSM to satellite all i get is a message in the center that says loading and it doesn't make any difference what browser I use, got any ideas whats wrong?
By Tommy on 1st June 2023
This is awesome!! Maybe add an option to change the color of the markers?
On 20th October 2022
Nice job! Yes, it is now working for loops, but it has a strange way to calculate distances. As I see in the map, it is as if it calculates distances in straight patterns, like flying between points. No road trips? :)
At least is it using Haversine calculus or Geodesic ones for these distances?
By Emiliano Llano Díaz on 26th April 2022
Emiliano, it should be working now.

By Emiliano Llano Díaz on 25th April 2022
What has happened to this app?
The "remove last marker" button and "clear map" etc have disappeared!!??
PLEASE! Fix these issues bc I enjoy using usually. The clarity of the satellite photos is lacking as well, making me wonder how old the images are. No need to slog thru what you *hope* is the right location, when clear sat views do exist!
By Chuey B on 10th March 2022
8,317 miles seem like an erroneous reading. Any test we do is <4000 miles
By Daft Logic on 24th February 2022
This shows to me that the distance between Madrid Spain and Asheville North Carolina is 8, 317miles, whereas Google Maps tells me that as the crow flies it is only 4,154 miles%uD83E%uDD37%uD83C%uDFFB%u200D%u2642%uFE0F
On 23rd February 2022
Love it. Use it often. BUT would be REALLY helpful if results/controls were directly below the map so wouldn't require paging back and forth.

On 2nd November 2021
Can this be in English. I look at foreign countries ie thailand and it is not in english

On 25th August 2021
a return to the glorious past. in the past it was easy to zoom around the world to any point without markers inserted at every spot. what ever happened to street views where available? I wish we could go back to the original user friendly version. I appreciate and commend your past efforts
By denzil on 31st July 2021
Steve, what happens when you convert to km? What does the output display say?
By Daft Logic on 19th July 2021
Hello I can't find out distance from specific markers when I convert to kilometers
By Steve Chong on 15th July 2021
Hi Ian, please get in contact and we can help out.
By Daft Logic on 14th June 2021
Saved route coordinates IS now fixed and working - including my bookmarked routes. Thank you very much!
By MC on 4th June 2021
Is there a way of drawing a circle on a map with the centre at, say, my home?
Because of Covid, we are limited to travelling max 5km from home.
I would like to be able to create, then printout a map with a 5km radius from my house, so that I can work out legal bicycle rides to try to keep fit.
By Ian Michael Baker on 28th May 2021
MC, thanks for reporting these two issues. They should now be fixed.
By Daft Logic on 26th May 2021
Since map-change update - Uploading Route co-ordinates does not appear to be working. Also I have some bookmarks of routes, with coordinates saved, if I follow the bookmark, I am simply presented with the whole world map, it does not zoom to the pinned route. I also tried re-creating (part of) a route, with about 5 or 6 pins, then generating a link... it did generate a "tinyurl" link, but that link, when followed, also does not revert to the route I just created... again the whole world map.

Still love the site though, will be awesome if you can fix this bug.

By MC on 21st May 2021
Probably no one else on this entire planet has measured and calculated more points and distances on the good old previous daft logic tool version than me. Now I recommend using Google Maps Distance Calculator for the purposes which were earlier feasible thanks to the good old previous daft logic tool version, even though the Google Maps Distance Calculator is unfortunately far from the previous easiness of the good old daft logic tool version. I would love to stay faithful to daft logic, however it unfortunately isn't possible and it's time to say goodbye !!!!
I have used your site for many years and have always loved it! the new updates are a step backward. My farm is now obscured with cloud cover and the resolution is far from what it once was. I will be looking for a new site to use now. My zip code is 46392.
By DavidD on 23rd February 2021
Hi Robert, unfortunately not. The old map interface came at a significant cost to us that was not feasible to maintain going forward. It is understood the loss of high resolution is a disappointment.
By Daft Logic on 16th February 2021
Hi Denzil, we are glad to hear you have been using this free tool for many years. We have had to move to a new mapping interface for costs reasons and to allow us to continue to provide this tool for free. It seems you are describing 3 features:

I cannot place markers at start/end points - not sure that was possible before?

lat/long - not sure what this means?

distance - not sure what this means?
