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.

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!!! put it back the way it was before upgrade.

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.

G'day, I have an apple mac and have been using this for a number of years for quoting in my acreage mowing business, but in the last 4 months, the updates make it unusable in the way I could before, in the following ways: To zoom in and out you have to slide your finger up and down the mouse like a trackpad, as there is no longer the and - icons on the bottom right. The street view disappears occasionally. Now the newest and biggest problem is that I can't print from a screen like I could before and the area is onlt a quarter of what I could print before and its impossible to line up. This was a great product but the recent updates have stuffed it for desktop users. Can we please get it back to the old way. Its great that its free, but if it was at least back in its old state then I would gladly pay a reasonable amount Regards Greg
By Greg Gorton on 14/04/2016
Hi, this is hard to define. All I can suggest is taking measurements on areas you have a physical measurement for and comparing.
By Daft Logic on 13/04/2016
Fantastic tool dear daftlogic. I've got an important question. How much is the accuracy of area calculator?
By Mr on 13/04/2016
Hi, sorry this is not possible right now. We will look in to this as a new feature.
By Daft Logic on 13/04/2016
This website is great! Is there a way to add labels to points?

Really cool. I'm using this to create recommendations on Marine Protected Area sizes in the Philippines. We also used it for our Dive against Debris. This tool helps marine conservation :)

Hi Franklin, this page is used to measure areas

This is exceptional. I can define paddocks and be more accurate on the feeding of the cows

Hi J, there is no set frequency. They are updated on an ad-hoc basis by Google.
By Daft Logic on 29/02/2016
Hi, How often will the maps update? We have been trying to get the area of a property for a few months that was under construction. Thanks!!
By J on 29/02/2016
Kyzer, thanks for the suggestions. We have implemented an option [Show latitude longitude grid]. The other 2 suggestions will go on the Further Uses and Ideas list as they need a bit more time to develop and test.
By Daft Logic on 24/02/2016
Hey! Feature Requests:
• The ability to hold down [shift] key to make 90° or 45° angles.
• The ability to select an area as an entirety and drag it around, copy/clone/duplicate it.
• The ability to toggle on an opaque overlay grid.
Great work! Thanks!
By Kyzer on 23/02/2016
Hi Ed, The best assumption is it doesn't know that there is a multi-floor building, just the land it occupies. So if you measure the outline for a building you will be getting a reading for the footprint of the building (1 floor).
