Hi Thomas, thanks for the comments. For #1, we will consider this.For #2, this can be switched off if you click on Satellite at the top right of the map then untick where it says 45 [degrees]

Hello, Great tool! This is the best Google area calculator tool currently available. Two suggestions: Can you add a marker showing the location of the property after I enter the address in the search bar and the property has been located? Not knowing this makes it very difficult for me to find a property especially if I am not familiar with the city. Also, is there any way for you to make this work with the latest google maps? This is because when I zoom in to take an area measurement, it actually goes into a axiometric aerial bird eye view, which makes it harder to to measure roof tops. Thanks!

Hi John, are you using this tool to measure areas or distances? There have been no updates to the method of measuring areas or perimeter of the area in the last year.
By Daft Logic on 15/04/2015
I have been using your tool for year however with the update the tool is way off. Something that 50 feet is now showing 95 feet. Please fix asap
By John on 15/04/2015
Would be nice if you could input a roof pitch

Hi TLC/Jimmy B, yes, it doesn't drop a pin. It isn't designed. No big reason, but it could be argued it could get mixed up with the pins that define the area boundary.
By Daft Logic on 15/04/2015
I'm still wondering why it won't drop a pin to indicate the exact address location.

I really appreciate this tool...thank you

Jim S, the Distance Calculator can be used to measure this.
By Daft Logic on 11/04/2015
Please show the distance - in the measurement I select - between the points as i plot them. Prefer you show the distance on the map between the points but ok if you show below the map as distance between point 1 and 2 is 180ft. Between point 2 and 3 is 84 ft. Etc.

The 2015 Google imagery was showing up but now the imagery looks to have reverted to an earlier date in some areas.
By Shane on 01/04/2015
this is got to be the most handy tool ive seen if you farm. easy to know area for spray or seeding. the other is for fencing knowing how much fence it will take to do a field. great tool !!!

On 24/03/2015, the best option is to switch to full screen then take a screenshot.
By Daft Logic on 26/03/2015
Thank you very much for putting this out. Super user friendly and an awesome resource!
By Tyler on 26/03/2015
Very nice, useful tool. Would love to be able to export area info to Office or Google docs. Am I missing that?

By ramesh on 23/03/2015
I was looking for this kind of tool for a long time. It is excellent, and if the marking on the map is done correctly, the area calculated is very accurate. I am very happy and thanks to Google.
By Amiri Kivambe on 23/03/2015
TLC/JimmyB here - Why will it not drop a pin on the actual address, like Google Maps does?
On 23/03/2015
Would be amazing for work if it displayed addresses somehow.
