Google Maps Area Calculator Tool

Use the Google Maps Area Calculator Tool to define an area and find out the measurement of the enclosed area. You are also able to save your areas for use later on. Click on the map to start drawing an area.

[Map Height : Small - Medium - Large - Full Screen]

Output : Current Area

0 m² | 0 km² | 0 acres | 0 hectares | 0 feet² | 0 square miles | 0 square nautical miles

Add a location manually (also accepts [latitude,longitude])


How to Use

  • Click multiple times around the map to define an area
  • The calculated area will then be displayed below the map

Other Options

  • Click [Delete Last Point] to remove the last point clicked
  • Click [Clear All Points] to remove all areas drawn
  • Click [Generate KML] to generate a KML file representing the last area drawn. Once you click this option, after a short delay, a hyperlink "Download KML File Here" will appear. From this link, you can download your KML file
  • Click [Create New Area] to start drawing anew area whilst keeping any existing areas on-screen
  • You can adjust the map size by clicking Small, Medium, Large or Full Screen
  • Click [Export Lat/Lng] to export a list of latitude and longitude coordinates to a text box below the map. You can then copy and paste these to an external system.

Hi, acres is one of the units output.
By Daft Logic on 18/07/2016
I want to know how many acres is a given area.

Pieter, there are icons to delete or rename the saved area just beside the list of saved areas on this page. Do these work for you?

Hi I want to to delete saved area and change the names of saved areas ? Pieter

Suggestion: include the possibility of measuring orientation angles
On 06/07/2016
Sampath, I'm not 100% sure what you mean. Can you explain in more detail please? There is a distance calculator for measuring distances.
By Daft Logic on 27/06/2016
HI , Can u add marker pen so as to do complex calculations and display length of each side ?
By Sampath on 25/06/2016
Helen, unfortunately it is not possible to do this.
By Daft Logic on 25/06/2016
Hi. how do I select an area in its entirety and then drag it around? I've outlined and saved an area and now I'd like to drag that outline over to another part of the map.
By Helen on 25/06/2016
Can saved areas show up in their own colours? It looks like all the areas I create are all the same colour, I'd like to see them differentiated!

Hi, does [delete saved area ] not work? Which browser are you using?
By Daft Logic on 20/06/2016
want to delete saved area
On 16/06/2016
Joachim, when this happens you can switch back to top-down view by clicking the icon that looks like four tiles. It is most often found on the bottom right corner of the map. Clicking on this will switch it back. I hope this helps.
By Daft Logic on 08/06/2016
Hi, love the idea, but there is one big problem for my use case: When I zoom in to neighbourhood scale in Oslo, Norwa (I want to measure a single property), the satellite map view suddenly changes to an isometric 3d view, whihc is completely useless for measuring land areas. I'm sure this is a "feature" added by google after your solution was made, but maps.google.com does not display this behaviour, so I'm confident they also have is some way of disabling it.
By Joachim Lous on 03/06/2016
I would like to see section lines on the map, would make it easier to find places with no address

This is great! It saves me lots of time from measuring lawns for estimates and jobs.

Hi, it uses the format 48.85837,2.294481 (The Eiffel Tower)
By Daft Logic on 15/05/2016
Love this tool. What is the format to enter a point manually using lat/lon? For example, I typed in 23.67e and it put a point somewhere in South America.

Q: How do you delete map file?
Can you confirm what you mean by map file please?
By Daft Logic on 09/05/2016
Innes, are you using a MAC or PC? In Chrome can you try clearing your temporary internet files then try it again? Regarding the pins being too close to draw a precise shape, does it help if you zoom in on the map to do it?
By Daft Logic on 09/05/2016
I just get "0 square metres" in Chrome. It works in Edge though, but you can't click near to existing points so it's not possible to draw detailed polygons.

Thanks for this, very helpful!

Before the update you could full screen and customize the margins, and print the map that you wanted to a full sheet of 11x8.5 paperwith out any ads or other junk showing...Now it does not work that way! I created an account like I was told by DRAFT LOGIC and it still does not work! I have messed around with this for hours and have not been able to print on a full sheet of paper like i use to!!! Toogle the borders of your property on the map, customize your print page...fail!!! put it back the way it was before upgrade.
On 29/04/2016
gabriel g, this can now be done if you create an account, save the areas then visit the user account page.
By Daft Logic on 29/04/2016
Hi, can you try printing the map without switching to full screen?
By Daft Lgoic on 27/04/2016
Since the last print update when I map out my selected area and enlarge map to full screen, it will not print what is selected...shows only the bottom half of the page???

Hi Greg,
1) The Zoom buttons should still appear at the bottom right of the map. This hasn't changed
2) Streetview will appear (or not) depending on there being Streetview imagery available
3) Print functionality has been changed recently. Content that is not to be printed is removed from the print, however it is recommend the map hight is set to small (above the map) to get the content to fit on a landscape sheet. I have tested this on Safari and Chrome on MAC OS and can get the print (map measurements) to fit on a landscape sheet.
