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.

Always, always a helping hand. Being using it for almost 3 years now.

Before the update....all photos were in the winter, with no leaves. Now I get see anything because of the trees in the photos.

Good job all. Very useful

Hi, can you see the "Output : Current Area"?
By Daft Logic on 30/01/2016
When I define area, only give me the perimeter and not the hectares. How do

Hi, when you click Generate KML do you see the option [Download KML File Here] appear just below?
By Daft Logic on 28/01/2016
Great website, but download kml does not work with Firefox
On 28/01/2016
Craig, thanks for the comments. We have just added some keyboard shortcuts, see the Keyboard Shortcuts heading for more information. There have been a few changes to try and improve the page layout and usability. For printing, I suggest doing it via Full Screen mode.
By Daft Logic on 28/01/2016
Fantastic program, I have been trying to find this type of program for our farming acreage for years, thank you. Are there any "hot keys" or function commands I can use while in full screen mode? Specifically to toggle on and off, to start a new area and see the acreage in area. Also it seems the map screen is either a tiny window or full screen (I have used the med, and large) is there a way to stretch the the window or put the acreage and commands to the side and locked so I don't have to scroll all around. Finally, how do I shrink the "area" which the program thinks I am viewing. When I print the information, it comes up with 3 pages of map but I only need one of them. I realize I can tell it to print only 1 of 3 or 4 pages from the print command in chrome. I have not found any print command on the page its self..

Hi, it is not possible to upload a KML file.
By Daft Logic on 21/01/2016
how do you upload your own kml file and compute areas in it?
On 21/01/2016
Hi, It should be possible to do what you say. If a new function to upload/import a KML to this page was added would this help? Please send a sample KML file from your GPS and we will look in to this. A contact email can be found here.
By Daft Logic on 20/01/2016
I am attempting to use the Area Calculator with my Raven Cruizer 2 GPS. I can create a KML file with the GPS. and save it to a jump drive. Is there a way to transfer the file, or combine it with a KML file created here? I really like this set up and use it regularly to measure agriculture areas. Thanks for making this tool available.

Hi M, thanks for the feedback. Just to check ... can you see the and - to zoom in and out at the bottom right of the map? I have added the color scheme suggestion to the Further Uses and Ideas list.
By Daft Logic on 11/01/2016
Thank you so much for this website. Have used it daily for over a year. As far as the update with the interface, can you please add the zoom in and out features for the area calculator. Also, in the future, would it be possible to allow different color schemes for additional output areas rather than just one. If that is possible, toggling between multiple areas would be fantastic. Thank you!
By M on 10/01/2016
Hi Brandon, thanks for getting in contact. Please try the text box below the map beside "Add a location manually". This should add a marker at the loction.
By Daft Logic on 07/01/2016
I'm on Google Chrome, and ever since the update with the new interface, an address marker does not appear on the building when the location comes up. Previously, when I typed in the address, the pin would fall right on the building. Now it's gone?

May i have code for this .. please Thank you,

Hi PK, thanks for the feedback and the detailed descriptions. The bug with Total Area should now be resolved. The height of the map should now size depending on the screen size viewing it. The end result is a large desktop screen should now have a taller map, yet mobile/tablet screens will not be as tall.
By Daft Logic on 31/12/2015
When you first access the page and enter multiple areas it will display the total area measurement. But if you make a mistake and "clear all points" followed by the re-entering of your multiple areas, it no longer displays the total area measurements. The only way to get around this is to refresh the page and start over. Also, on my desktop the viewing window for the map is so narrow top to bottom, more so than the old look. It would be nice if this was longer or adjustable.
By PK on 30/12/2015
Hi Jim, Thanks for the feedback. The total area should be displayed below the map once the 2nd area has been drawn. Please see this screenshot ... http://postimg.org/image/ka542uyj7/ Let us know if it doesn't appear for you...
By Daft Logic on 26/12/2015
Hello, This is an awesome tool!!! What happened to the total acres when calculating multiple areas? I can no longer find it. That's is a very important feature v/r Jim
On 25/12/2015
Thanks for the feedback. The purpose of the change is to ensure the page displays correctly on mobile and tablet devices. We will endeavour to address any issues that are deemed to be a step backwards. Can you confirm what the error is when to try to log in? Does it not recognise the username/password?
By Daft Logic on 24/12/2015
What was wrong with the old Daft Logic.? This one is too complicated and I can't even log in to use it. You guys at Google ruined a real good tool!
On 23/12/2015
Great tool. Prefer the old display though. I liked being able to measure and check the area without having to scroll down the page. It would be nice to have the outputs next to the map
On 23/12/2015
Amazing Job. Tool is great, but what has to be really commended is the simple intuitive controls to fix the area.
By TM on 23/12/2015
Hi Moe, when this happens you can revert back to the plain 2d view by clicking on the icon with four squares found at the bottom left of the map.
By Daft Logic on 21/12/2015
It appears that the image has now become more 3D than it was before, its now more of an angled overhead view instead of a 90 degree satellite image. Can this be toggled?
