How to measure my lot size?

Enter your address, outline your lawn on a Google map, and voilà! See your lot size on a screen! You can draw multiple areas for one address; backyard, front, or side yard; it will summarize the square footage and show results for each lawn.

How to Manually Find Your Property’s Square Footage 

If you’d like to measure your yard the old fashioned way, follow these steps:

  1. Walk the length of your lawn, figuring that one pace equals about 3 feet. Do the same with the width of the lawn.
  2. Then multiply the length by the width to arrive at the total. Make sure you subtract the square footage of your home and driveway when calculating the total square footage of your lawn.
  3. If your lawn has an irregular shape, try dividing it up into a number of square areas. Calculate the square footage for each area, then add the figures together to reach your total lawn size


Determining the Size of Area

Step 1: Inspect the Area

The first piece of information you need to know is the shape and dimensions of your lawn, particularly the width and length. You will want to measure and multiply the area length times the width in feet until the square footage is 1,000 sq. ft. and mark off this area with the help of a marking tool like washable paint or objects to distinguish the treatment areas border line. 

Step 2: Convert Measurements

If your yard is rectangular or square, measure the length and width then multiply together (length X width = square footage). For example, if your yard has a length of 10 feet and width of 8 feet, you would multiply 10 by 8 to get 80 square feet.

Be aware for triangle shaped lawns, you will measure the length and width, multiply together, then divide by two ( length X width / 2 = square footage).

If your lawn is a not a perfect rectangle, break the lawn into different sections to measure more easily, then add measurements together to get the area’s total square footage.

For treatment areas with flowerbeds and other obstructions in the yard you will measure the square footage of the object and subtract from your yards total square footage.

Example, you have a property that is 12,000 sq. ft. and in the middle you have a landscape bed with a length of 3 feet and width of 2 feet. You will multiply 3 by 2 to get 6 feet, then subtract from your yard total.

  • 3 ft. X 2 ft. = 6 sq. ft. 
  • 12,000 sq. ft. – 6 sq. ft. = 11,994 sq. ft. 

Therefore, you will treat an area with 11,994 sq. ft. 

Irregular Shapes

Geometric shapes are common in home lawns, but more often, lawns are irregularly shaped. Many of today’s landscape designers use principles of flow and balance to break up straight lines. This gives the lawn a more natural and aesthetically pleasing appearance. In some ways, irregularly shaped areas are easier to measure than geometric shapes. There are two easy to understand methods for determining the area of irregular shapes. The offset method is most often used to measure lawns of irregular shapes. Another is the average radius method.

Convert among square inch, square foot, square yard and square meter

You could, for example, perform all of your measurements in inches or centimeters, calculate area in square inches or square centimeters then convert your final answer to the unit you need such as square feet or square meters.

To convert among square feet, yards and meters use the following conversion factors.  For other units use our calculator for area conversions.

  • Square Feet to Square Inches
    • multiply ft2 by 144 to get in2
  • Square Feet to Square Yards
    • multiply ft2 by 0.11111 to get yd2
  • Square Feet to Square Meters
    • multiply ft2 by 0.092903 to get m2
  • Square Yards to Square Feet
    • multiply yd2 by 9 to get ft2
  • Square Yards to Square Meters
    • multiply yd2 by 0.836127 to get m2
  • Square Meters to Square Inches
    • multiply m2 by 1,550 to get in2
  • Square Meters to Square Feet
    • multiply m2 by 10.7639 to get ft2
  • Square Meters to Square Yards
    • multiply m2 by 1.19599 to get yd2


The area of a rectangle is found by multiplying the length (l) by the width (w).

Area = (l)(w)

Example 1:

Calculate the area of a rectangular lawn with a length of 50 ft and a width of 25 ft.

Area = (l)(w)

Area = (50 ft)(25 ft)

Area = 1,250 ft²

    I never would have thought to use Google Maps to measure my lawn!! This is SUCH a helpful tip! Now I don’t have to go out and buy one of those measuring wheels!! Thank you so much!!!


How It Works

Use buttons on the top right to start or stop drawing, to open your list of addresses, or to get a quote. When you click on the area you draw, the small infobox will show its size in a square foot. You will also see the size in the right side panel by each address you save. Remove the address by clicking on the "trash" icon. If you have saved addresses, use the "book"-alike-icon to open the list and click on each address to see areas (lawns) you drew previously. Edit the lawn area by clicking on it. You can rename it by using a blue round "pencil"-icon in the infobox.
