How To Measure Your Lawn To Calculate How Much Turf You Need

Why You Need to Measure Your Lawn’s Square Footage

Every bag of lawn product that you get at the store, whether it be fertilizer or grass seed, will state the approximate square footage it will cover. You should aim to get just enough product to cover your square footage, which will benefit you because:

  • You won’t overspend for additional product you won’t need
  • If you use a product past its recommended use, you could damage your lawn – buying just enough product will ensure this doesn’t happen
  • You won’t have to run to the store to buy more if you didn’t buy enough the first time
  • If you buy too much product, you avoid having to store it until the next season

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. 

How to measure your irregularly shaped lawn

So, your garden is a bit of a tricky shape. It can be difficult to find the exact area of an irregularly shaped garden but it can also be done! As a guide we recommend you firstly divide your irregularly shaped lawn into sections of regular shapes, for example, circle, square and triangle. These will be more manageable sections which are easier to measure. See the below image for an example of how to measure an irregularly shaped lawn by using the circle and rectangle formulas.

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

Save Your Information

Save and edit your addresses: keep emails, phone numbers, names, and notes. Whether you are a homeowner or a contractor, it’s super useful to have your area measurements at hand.

How to measure your circle lawn

It’s back to school for this one, folks. For circular shaped lawns we have an easy formula to follow to get the area of your lawn – you might remember it from your maths class days – it’s called Pi! (π). You can calculate Pi by finding either the radius or diameter or your circular lawn. For a quick classroom recap, the diameter is the width of the circle, and the radius is half the width of the circle.


Another great measuring option

  1. On your computer, open Google Earth.
  2. Search for a place, or select a location on the globe.
  3. On the left, click Measure Click the map to set measurement points.. Google Earth will switch to a top-down view.
  4. Click the map to set measurement points.
  5. To remove a point, on the right, click Undo To complete your line measurement, double-click on.
  6. To complete your line measurement, double-click on your last point, or click Done .

On the right, you’ll see the length. Tally up the total square footage and bingo you have your lawn area size, now you can get a price quote instantly for either installation or just the sod and soil materials.
