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.

Login to Save and Load Maps

Future Uses and Ideas

  • Allow multiple areas to be added to a project, saved then loaded afterwards
  • Allow upload a KML file and calculate any areas of polygons inside
  • Allow export of lengths of perimeter sides
  • Allow different color schemes for additional output areas rather than just one
  • The ability to select an area as an entirety and drag it around, copy/clone/duplicate it
  • Option to subtract sub area from main area

This website is absolutely disgusting, is a disgrace to software itself, websites like this make Bill Gates cry. I hope you find it hard to sleep at night, because i did, stressing because i was unable to figure out the area of my schools campus due to this website.

I hope you fix this website and make sure average people like me are not left upset because this website doesn't work.

Hi dashx, please get in contact directly to discuss this further.

Hey devs, Thanks for this great tool! Does it have an API which I could use to integrate it to my website?
By dashx on 9th November 2016
great tool thanks.

The program is great for what I need to do except that, as another commenter pointed out, the calculated areas don't appear to be highly accurate. Using latitudes and longitudes with 10 decimal places, I plotted a 5-sided area, which the program said was 23.58 acres. As I wanted to subdivide that area in half, I made a western parcel with, according to the program, exactly half the original reported area, 11.79 acres. But the remainder, the eastern parcel, was said to be 11.88 acres. Possibly, rather than being the fault of the program, it could be that more than 10 decimal places of latitude and longitude are needed for the precision I was seeking.

Any way to get parcel delineations?

Abhay, it has not been designed to be used in this way. It is not supported. If you wish to discuss a custom implementation, please get in contact.
By Daft Logic on 4th October 2016
Can we integrate the area calculator tool in our website (programmatically using CodeIgniter)? If Yes then can you please let me know how can we achieve it and whether there is any reference link.

"Is it possible to create polygons inside area? I can't find that option."

I meant, after I have made an area, is it possible in this area draw out, for example, buildings, ponds? I want to measure accurate area of the agricultural field, but ponds and buildings are not countable in the area of agricultural field and they interfere the measurings.

Hi, if you are looking to measure distance, please use the Google Maps Distance Calculator. The output on this page is the perimeter and for 2 points, its twice the distance between them.
By Daft Logic on 22nd September 2016
Length of 2 points seems off right now. Was working last month

I enter a 10 x 10 degree square: 30,30; 30,40; 20,40; 20,30; (1,115,082.82 km^2) and another one just above it: 30,30; 30,40; 40,40; 40,30 (1,007,850.07 km^2). Adding the two areas gives: 2,122,932.89 km^2

However, if I combine the two to make a single "rectangle", with the same boundaries: 40,30; 40,40; 20,40; 20,30; I get an area of 2,106,683.4 km^2

Now, the really odd part: if I add in the 2 "middle points": 40,30; 40,40; 30,40; 20,40; 20,30; 30,30; I get 2,122,932.89 km^2 !!!

Hi %u0100ris, I'm not too sure what you mean. Can you explain in more detail please?
By Daft Logic on 8th September 2016
Hi there!

Is it possible to create polygons inside area? I can't find that option.

By Āris on 8th September 2016
so awesome i love this tool
By Jason on 7th September 2016
If you click the [Toggle Markers] button it should hide the markers for you.
By Daft Logic on 31st August 2016
Is there a way to remove the markers and just show the area measured?

Hi Harold, if you have previously created and account and saved an area you need to log back in to see all your saved areas.
By Daft Logic on 8th August 2016
On 06/08/2016, It seems you are using the area of the perimeter to measure distances. For an area with two points, the perimeter on this page is twice the distance between them. Please use the Distance Calculator to measure distances.
