Area calculator: Find the area of any simple shape on a google map

Zoom in, or enter the address of your target start point. Then click on your start point on the map, followed by all the subsequent points along the outside edge of the shape you want to calculate the area of. As you add points the area will be updated below and converted into several measurements. This tool is useful for finding the approximate acreage or a tract of land, the square footage of a roof, or any other instance where you need a good estimate of the area of something.

Measure the area of a plot of land

The easiest way to measure the area of a plot of land is to start by entering an address that is associated with the plot of land you need the area of. In rural areas where an address may not be available, you can enter the cross street or even the GPS coordinate of a point on the land. For GPS coordinates be sure to enter the latitude followed a comma then the longitude ex. (41.87811, -87.629798). In any case this will place a marker that you can use as a reference point to draw the area on the map. Once you are finished drawing the area calculator will display the area of the shape above the map.

How to use the google maps area calculator tool to measure a roof

Special precautions must be taken when measuring the area of a roof. The images that appear on google maps are often at a slight angle, which combined with the angle of a roof can cause errors. For this reason it is best to outline the roof at points which are all at the same elevation. On a simple house for instance you would only click on the corners of the roof and not on any points along the peak as that would cause an error. After measuring the area of the footprint you can estimate the actual roof area based on the angle of the roof. Similarly if you using the area calculator tool to measure a roof with multiple levels, you should do the individual section separately.
