How can I benefit from having accurate dimensions?

Having accurate dimensions can help your metal building supplier to both confirm that your building is suitable for space, but also create 3D CAD drawings to show you what your property will look like.

This can be very helpful when you are going through the approval phase of your purchase, so you can confirm that you are happy with the plans.

Plus, having this information means that when you are purchasing land, you can make sure it is the right size.

How do I work out how many acres I have?

You can work out your lot size regarding acres by merely multiplying the length of your lot by the width.

This will give you the square ft of your lot.

Then, you divide this number by 43,560 to work out the full acreage of your property.

For instance, if your lot were 130,680 sqft, you would divide it by 43,560, and in the result, you would be left with a lot dimension of three acres.

How to Calculate Acres

The easiest way to calculate the number of acres in your land is to use the calculator above. If you know the length and width, simply enter them. The calculator will provide the number of acres, as well as the area in other units.

It will also give you perimeter. If you already know the acres but want the area in other units, use our acreage unit conversion tool.

To calculate acres by hand, multiply your length and width (in feet) to get square feet. Try our length conversion tools, if needed. Then divide by 43,560 to determine the size of the land in acres.

Example: Your city house lot is 33′ wide by 102′ long. How many acres do you have?

33′ × 102′ = 3,366 sq ft 3,366 sq ft ÷ 43,560 = 0.077 acres

You can quickly find the square footage of an area using our square footage calculator.

Unfortunately, property is not always divided into perfect squares, and finding the acreage of irregular shapes can be a little more challenging.

The trick to finding the size of these irregular plots in acres is to break down the land into smaller geometric shapes first. Find the size of those smaller spaces separately, and then add them together.

Another great way to find the area of irregular shapes is to use the interactive map above to determine the actual size in acres.

Information

The area calculator tool allows you to find out the area that is enclosed inside a closed polyline overlaid on a map.

Measure an area on Google Maps using a third-party tool

If you need to measure areas on Google Maps often, then I will recommend you to use a third-party tool instead. Google Maps built-in area calculator is rather limited in features. For example, it’s limited to showing measurement in square footage and square meters only, what if you need to measure in acres on Google Maps? This is where a third-party tool will help you.

Although there are many area calculator tools for Google Maps, but I’ll recommend DaftLogic Area Calculator for the ease of use and it is completely free.

Open up DaftLogic Google Maps Area Calculator and at the top provide the required location using multiple methods, including text search, ZIP code, UK Postcode, GPS coordinates, and current location.

Now left-click on a corner of the land to drop a p

Now left-click on a corner of the land to drop a pin and continue dropping pins to create a boundary. The map will automatically fill the area with color to make it easier to distinguish the area selected. The line and fill color, both can be changed if needed.

Once an outline of the land is drawn, DaftLogic wi

Once an outline of the land is drawn, DaftLogic will show its size at the bottom in square feet, square meter, acres, hectares, square miles, and square kilometer.

Using the tool is similar to Google Maps’ built-in

Using the tool is similar to Google Maps’ built-in tool. You left-click to place a point and right-click to remove one. Each point is draggable to adjust as needed, and you can toggle markers on/off for better visibility.

You can also use the “Create New Area” option at the bottom to measure multiple areas on the map at the same time.

Overall, DaftLogic gives much more control over me

Overall, DaftLogic gives much more control over measuring areas on Google Maps and it offers measurement in the most needed measuring units as well.

Warnings

  • Land is often sold XX acres, (+ or -), leaving the purchaser with less land than advertised.

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 areas rather than just one (+2)
  • 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
  • Saved Areas : Allow them to be loaded or unloaded independently
  • Allow area fill and perimeter color to be changed after the area has been added

How accurate is the acreage estimation? I use this daily to get a rough idea of fencing and pasture acreage

Hi Neo, that can be done on this page : Distance Calculator.

By Daft Logic on 15th June 2022

Super useful, It would be nice to have the distances between points.

By Neo on 14th June 2022

Add a option to print the selected Area along with details as PDF

Briliant tool!

On 28th February 2022

Great tool thank you! Very useful to draw areas around cities to see how big and/or dense they really are. Only feature I would request is the ability to move a selected area around. It’d be useful to able draw an area around one city and move or duplicate that selection on top of another city so I can compare their shape and size in a quick and visual way.

Thank you, this tool aided a law engineer in Mexico, to save an area of 18.54 acres of city forest

A very helpful tool

Is there an API for this calculator that we can use?

By Ray on 20th July 2021

great tool thank you

Thanks for Such nice Software. I love your work

By Shahzaib Rasool on 22nd June 2021

Hi, no, the code is not open source.

By Daft Logic on 14th June 2021

is this code opensource? Can we get this tool’s code? please provide code and more references. Thanks

On 14th June 2021

Thank you.

Hi I am in need for a tool that i can draw on and given a log, lat i want it to return if the location is inside my drawing or not. Can i use this tool to do it? or any other suggestion?

By Mithu on 25th April 2021

update please

On 20th April 2021

would love the option to change area colors when adding a new area for example area 1 outline and fill color be different then area 2 fill color and outline

By Toro Blacktop & Concrete on 18th April 2021

Johnnie, thanks for the feedback. There is no straightforward way to do this. The only option is to reset back to an empty map then load the one or more required areas. We will add this in to the Future Uses and Ideas list.

By Daft Logic on 25th March 2021

What a fabulous tool! I use it all the time. Thank you! Is there a way to turn on multiple saved areas at a time without the areas merging into one?

By Johnnie on 23rd March 2021

Amazing tool! Thanks!

By Lucas Eugenio on 22nd February 2021

I understand the purpose and the need for ads for your site, but is there a way to move the ad between the map and the data for the measured area? I need to be able to take snips showing both the map and the data together, but the ad is the only thing that can be seen.

By Shawn on 19th January 2021

GJ, if you wish to measure length, please try Google Maps Distance Calculator.

By Daft Logic on 20th December 2020

Can you indicate the length of each line/side of an area? Great tool you built there, man!

By GJ on 20th December 2020

Very useful tool for me. A little suggestion if the outline of each area can use a different color, so that adjacent areas can be seen clearly if they overlap.

By Akai on 30th November 2020

I was asked to calculate volume of a particular airspace of particular area, and instead of dealing with irregular polygon, this website saved me plenty of time, Excellent!!
