[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])

  • Click [Clear All Points] to remove all areas drawn

  • 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 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.

How do I open a saved site?

I want to know how many acres is a given area.

Hi I want to to delete saved area and change the names of saved areas ?
On 7th July 2016
Suggestion: include the possibility of measuring orientation angles
On 6th July 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 27th June 2016
HI , Can u add marker pen so as to do complex calculations and display length of each side ?
By Sampath on 25th June 2016
Helen, unfortunately it is not possible to do this.
By Daft Logic on 25th June 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 25th June 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 20th June 2016
want to delete saved area
On 16th June 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 8th June 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 does not display this behaviour, so I'm confident they also have is some way of disabling it.

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 15th May 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.
