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

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?

By Daft Logic on 16th February 2021
I have used this site for many years and am disappointed with recent changes. I cannot place markers at start/end points, lat/long and distance. is it possible to revert to the previous more useful program?
By denzil on 15th February 2021
In the old map many urban areas switched from satellite to aerial photography on very close-in zooms. That feature seems to be gone now. Was the main reason I used this site vs Google Earth, etc...

Any chance of it coming back?

By Robert on 14th February 2021
Like the new look, but miss being able to search for elevations.
On 6th February 2021
Cleared cookies and browser history now markers are permitted. Strange.
By Paul D on 6th February 2021
Hi, Using Linux Mint 19.1 32 bit with Firefox 79. No script blockers or add blockers active.
Cannot place markers or any points on the map.
New map looks nice.
By Paul Dearing on 6th February 2021
Gillertron, more updates:
1) Autopan issue is now fixed
2) "The segment in-between two markers" is back
By Daft Logic on 5th February 2021
Firefox56, can you try a full page reload. Alternatively clear temporary internet files and try again. if it still doesn't work, can you confirm your platform and browser? Thanks
By Daft Logic on 5th February 2021
Gillertron, thanks for the feedback. To address your comments:

1) The precision of output has been reduced from 2 DP's to 1. Displaying more than 2 DP's was somewhat misleading. It gave the impression that the accuracy was higher than it was. Outputting 1 DP better reflects the accuracy of the estimated distance output. Anymore is misleading as there are other factors that introduce a margin of error. For example this tool has no consideration for elevation variation over the route.
2) Agreed. This a bug. A fix has been applied
By Daft Logic on 5th February 2021
Hal (9K), we are taken aback by your foul language. For that reason you will not be getting a response.
By Daft Logic on 5th February 2021
Ever since you implemented Leaflet maps, I cannot set or see any markers anymore, and consequently can't measure anything.
By Firefox56 on 5th February 2021
Additional things I noticed not working w/ recent update...
1. You have to toggle auto pan on/off again to get it to work the first time.
2. You can no longer click the segment in-between two markers to create a new marker
By Gillertron on 4th February 2021
6.0 1st February 2021 Implemented Leaflet Maps < Recent update broke map functionality.

On Chrome incognito / safari web browser it works alright... I few things I noticed:
1. Distance (for miles) only tracks to the 1oth of the decimal -- 0.1, 0.2, etc... no longer 0.25, 26, etc...
2. Clicking on an already placed marker doesn't worked, AND it breaks the tool. Once you click on the already placed marker you can no longer place additional marker.

Please fix, or revert to previous version. This tool is super, super awesome - hate to see it broken!
By Gillertron on 4th February 2021
Whats happened? Wen I click to select the start of the distance I want to measure it doesnt place a marker. I can no longer measure distance?
On 3rd February 2021
How do I get the map prior to 2/1/2021??? This was a BAD idea!
On 2nd February 2021
Questions and observations:
1. What happened to the little circle between waypoints, that allowed the addition of another waypoint between the two?
2. I recall the ability to click on a waypoint and having the option of deleting it. It's possible I'm thinking of a different site or app, but I don't think so. Whatever happened to that?
3. So far, I've had to reload this page 3x because it stopped responding. Altho, it seems to be working okay now.
4. You ****** with it and now it's ****** up. Thanks. Looks like I'll be searching for another site to use.
By Hal (9K) on 2nd February 2021
