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.


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.

Would love to allow ads for your site. You should earn for your efforts. Sadly, sticking an ad between the map and the distance counter, renders this map useless to me. move the ad to above the map or below the distance readout and we are gold.

Super great tool for calculating a running distance.

What is the distance between -9 and 5 on a number line? *

I am grateful that this distance calculator exists. I enjoy mapping out new routes for my exercise routine. Thank you for creating it and for the upkeep!
By Zoe Morosini on 4th August 2020
Very easy and useful tool, thanks.
By godfrey b. on 25th July 2020
Use to love this tool until you added all the commercial bisiness locations. Now it is almost impossible to make this work anymore using markers with out clicking on a business, then when you try to close the business pop up it lays another toggle marker where you don%u2019t need one. News flash for you, NO ONE uses this app to search for a place to eat lunch or buy flowers. They use it to measure distances mainly for outdoor pursuits!

I've been using this tool to gauge point-to-point links for Wi-Fi gear for the last decade. Has always been spot-on for hundreds of links and thousands of satisfied customers. If you're ever in the Coachella Valley and need gigabit Wi-Fi, let me know and I would be glad to hook you up!

This tool is infallible for Real Estate brokers and all the people involved in plotting land.
Your greatness doesn´t stop at the awesomeness of the tool but in the spirit that made it available for the layman, like me.
Thank you so much!

I use this awesome website for tracking the path of ocean swells traveling from a storm to the coast. Would you consider making a similar app for offline use? If not, can you recommend an app that has similar functionality as your website? Thanks.

Thank you for this great free tool, I've used it every time I map out a new kayak or canoe route.

Plenty of people complaining about something that they haven't paid a dime for, you need to check that entitlement. Pretty easy to find any given location without a search if you have half a brain and know basic geography

Hi Denzil, there are quite a lot of users using this free resource as normal. It seems the issue you have is specific to your setup in some way. Can you try a different web browser or a different machine to see if it works there?
By Daft Logic on 12th March 2019
it sure is a shame to see such an excellent site go down so fast for whatever reason. there must be a lot of disappointed users out there that feel the same way as I do.
By denzil on 12th March 2019
whatever happened to this site which I have used for many years. now all I get is a blank screen when I call up the map. it is so sad to have the functionality of this site.
By denzil on 10th March 2019
I clicked the 'load the map" button but I still get a blank map area. I am not sure what to do to correct this situation
By denzil on 17th February 2019
denzil, you need to click the [Load The Map] button] to start using it. Can you confirm you click the button first?
By Daft Logic on 10th February 2019
I have used this site for years without any problems. However, of late the map does not show up on the screen so the whole program has become redundant, as far as I am concerned. Is there anyway you could resolve this for me. Thanks and I look forward for a solution.

Still does everything I need, great site. F11 and Ctrl sorts the small window issue
By Kip on 19th September 2018
Hello! Do you take requests? I would love it if you would set it to remember the auto-pan setting.

I'd like to go a step further, and suggest that auto-pan should default to off??!! Personally I find that a) it is disorienting to have the map move on me, and b) once place a marker, it's basically a guarantee that that location is the one location on earth that you are not going to want to be in the middle of your view anymore!
On 2nd September 2018
I use this for getting distances for new holes on disc golf courses we take care of. It's surprisingly accurate. Thanks!
On 22nd August 2018
Fantastic site for plotting runs/distances for routes.

Always use it, and the lack of address searching hasn't stopped this being one of most helpful free tools out there!
