Area Calculator Tool

Use the Area Calculator Map to draw an area on a map 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

[Map Height : Small - Medium - Large ]

Find Location

Current Measured Area

0 m² | 0 km² | 0 acres | 0 hectares | 0 feet² | 0 square miles | 0 square nautical miles

How to Use

  • You can add multiple areas by starting a new area after one is completed
  • Click [Delete All Areas] 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

Comments For This Page

Yes you can enter more polygons without pressing a "add more areas" button, but if you try to ammend any node of a a map, it thinks its a new map and enters a new node even though it moves the node that you are editing. then you have a sticky node that you cannot delete which follows you with a dotted blue line. If you try to delete last node, it does strange things and renders your last area obsured out of shape and you then cannot edit it, and you have to re-start again.

go back to the way it was, this is terrible!!!!!!
On 19th April 2024
Once you delete all areas you cannot draw any longer, you have to press F5 refresh and start again, also there is no way to do 2 or more areas any more, can we please have the previous version again, even though the distances are great, but funcionality sucks
By Naeem on 18th April 2024
Just give us 2 versions... (the last stable one and this one) the other worked perfectly on mobiles, this one does not, and if you select satelliet, and wish to change back, you caannot, the colours dont work any more etc. etc etc.

The move to Leaflets API was a massive mistake as next to all functionality across desktop/mobile usage is gone.
By Roon on 17th April 2024
Why on earth (pun intended) would you launch a COMPLETELY NON FUNCTIONAL version?? The previous version was so easy and so helpful. This is useless. The person(s) responsible need to find a new line of work. Xb
On 17th April 2024
Please bring back the old version. If it's not broke don't fix it.
By Craig Kimbrough on 14th April 2024
Apart from all the other comments, with which I agree, the place names are now all in local languages. This makes it impossible to navigate the whole world unless you're familiar with all the languages and alphabet forms of the whole world, so this excludes about 99.99999% of the world population.

The area plotting process is no longer practical for measuring complex or precise shapes and the ability to zoom in or out or make fine adjustments during the plotting procedue no longer exists.
Street view has gone
The zoom in zoom out facility moves only in giant leaps of scale and this together with all the other issues has transformed the Daftlogic area map from the very best map I ever used to the very worst.

Did we time travel back to 2004? This is awful - developers should be ashamed, used to be a great product. Probably Bidenomics
By Sam Jenness on 12th April 2024
the lat/lg waypoint that shows when you hover above the flag is no long there. Neither can you input waypoints anymore.
I'll check back in half a year
On 12th April 2024
this is terrible what happened?
On 12th April 2024
R.I.P Daft Logic
On 12th April 2024
It is terrible , bring back the old version

On 9th April 2024
I need this back to how it was. it made bidding jobs wonderful please fix !!!!!!!
On 9th April 2024
What on earth has happened to this?
By Tom on 8th April 2024
Wow, i have loved Daftlogic map area tool for seemingly forever now. I came today to plot a parcel and absolutely HATE V7.x
Its no longer useable in its current form, like basically ALL the 30 comments it lets me see please revert back to V6.
out of the current 1775 comments i imagine MANY are in dislike of this current version.
By Very Sad Canadian. on 6th April 2024
Never had a reason to look elsewhere before the recent update. Isn't the point of an update to make improvements? It's less user friendly, less intuitive, fewer features and less accurate than before? I have no words.
On 4th April 2024
We have been using daft logic area map for years now. Whatever change has been made the map is unusable, the ability to pin out an area is gone. Unfortunately I%u2019ve had to start using a different app for area finding%u2026 soon once I become familiar with the new app I%u2019ll no longer need to visit Daftlogic. After reading the comments I feel I am not alone.
Respectfully submitted
On 4th April 2024
There is a clitch that after deleting the area twice. It does not click new area and you have to refresh.
Could you find the bug?
Also, thanks for the bottom to delete the last point.
On 4th April 2024
Where the hell is satellite view? Totally unusable without it.
On 3rd April 2024
New version is unusable. Off to find a new program to fit my needs.
On 31st March 2024
please change it back, it's completely useless now
By JKD on 28th March 2024
new version is so useless ..
please revert it back.
By somnath on 25th March 2024
Hi Guys.
I have used this for years but with the latest update I cant seem to do anything I use to.
So I am now going to find another website that will.
But thank you for the use of what use to be an awesome GPS mapping programme
On 25th March 2024
This is terrible
On 25th March 2024
Once an area is deleted, you have to reload the page (which resets all areas and zooms out to world view) to start a new measurement? That doesn't make much sense.
On 25th March 2024
I've been using this app since 2016. This new version is completely unusable. I can't get perimeters listed wit the area output & there's no total quantities for when multiple selections are made.
By Unhappy Long Time User on 25th March 2024
I realise & appreciate that the previuos excellent user friendly version was free of charge (and thank you for that) but this 'new' version is simply unusable. None of us can make it work, even our programmer. We will happily pay a fee for the previous version if that helps, but please bring it back - now!
By Paddock Services on 25th March 2024
Please revert back to the previous version as soon as possible. Have used this excellent facility for years as we do a lot of work for private clients with land holdings of various sizes. Now, at the start of the new season cannot begin to make use of this new version which does not deliver a simple and practical way of finding and then measuring areas
