Lawn Size Calculator
Use this free lawn measuring app to accurately measure your yard size online.
My lawn size calculator uses satellite imagery from Google Maps to measure your lawn.
Sarah's Lawn Square Footage Calculator
Use the free mapping tool below to map your yard and measure your lawn size. Search your address and then use the “Draw” button to map the outline of your yard.
I recommend mapping individual sections of your lawn (front yard, back yard, side yard, etc.) so that when you apply fertilizer, herbicide, or grass seed you know exactly how much to spread in each lawn zone. The lawn measurement tool will add up these totals for you so you know how much product you need to order to cover all of the areas of your yard.
And if you have a pool, shed, garage, or garden that sits in your yard and which you want to exclude, simply outline it separately, then subtract that square footage value from your total lawn square footage by clicking the “-” button.
When you’re finished, click “Save My Map” and I’ll email you a private link to the lawn drawing you created. This way you can bookmark your link and come back any time to remind yourself of the square footage of each area of your yard.
Ok, Let’s Save Your Custom Lawn Map!
Just tell me where to send the map you drew of your lawn. You’ll instantly get an email with a private link to the custom lawn drawing you just created.
GENERATING
Now That You Know Your Lawn Size
Once you’ve measured your lawn size online, you will be able to save time and money buying lawn care products to feed and care for your turfgrass.
There’s nothing worse than wasting money by purchasing more herbicide than you need (only to have it go bad), or to be a few bags short of the amount of fertilizer your grass requires.
Let’s be honest – we’ve all made that second run to the store at least once!
But even if you know the size of your lawn, and how much product to order, you still have to know how to apply it properly to get even coverage and great results.
Here is my top tip for beginners. It’s an easy way to keep things simple and get perfect results every time:
Plan Your Route, Half Your Material
One of the biggest mistakes people make when using a broadcast or drop spreader is to put all of the material needed to seed, fertilize, or treat their lawn in the hopper.
Do so and you risk running out of product before you finish walking your lawn (meaning you over-applied everywhere and part of your lawn got nothing).
It’s a big problem – here’s how to avoid it:
- Once you calculate your lawn size and understand how much material you need to spread in that area, split your fertilizer or seed in half. Add half to the hopper, and start by putting a header strip around the perimeter of your lawn area (pictured below in BLUE)
- Next, finish spreading the first half of your fertilizer by traveling back and forth across your lawn (North / South) inside your header strip.
- Finally, load up the other half and walk in the opposite direction (East / West) across your entire lawn.
This allows you to get complete, even coverage across your entire yard while applying the perfect amount of fertilizer, grass seed, soil amendment, or herbicide product.
And if you are applying liquid fertilizer or herbicide across your lawn, you can take a similar approach to ensure even coverage and to make certain you aren’t wasting any of your material on the street, sidewalk, or walkways around the perimeter of your yard.
Finally, if you’re struggling to know what to buy, you may find my favorite product lists a helpful starting place that can save you some time sifting through the thousands of reviews online.
