Search your address, trace the lawn on the satellite view and get its measured area in square metres. Nothing you trace is stored or sent to LawnSuite.
The map couldn't load. This free tool has a daily limit on satellite map loads and it's been reached for today. Please try again tomorrow, or measure your zones directly inside LawnSuite.
Your block size is on the rates notice or the real estate listing. Your lawn size isn't, and they're not the same number. A 600 m² block might carry a house, a driveway, a shed and garden beds that leave 220 m² of actual turf. Product rates and seasonal plans are worked out per square metre of lawn, not per square metre of land you own.
A tape measure works for a plain rectangle. Most home lawns aren't rectangles. They wrap around garden beds, narrow past a side path, or open into an L-shape behind the house. Tracing the actual outline on a satellite photo gets the real number without the maths of breaking an odd shape into rectangles and triangles by hand.
Say a block is roughly 20 m deep by 12 m wide, 240 m² all up. The house footprint, driveway and two garden beds take up about 95 m² of that. Trace just the lawn on the satellite image and it comes out at 145 m², the number that actually matters for a fertiliser or herbicide rate, not the 240 m² on the block plan.
If the lawn has a front and back section, trace each separately. The tool adds them into one running total, so a 90 m² front lawn and a 55 m² back lawn show as two rows and a combined 145 m² total, ready to copy into a rate calculation.
Each point you place is a latitude and longitude from the satellite map. The tool projects those points onto a flat plane centred on your trace (accounting for the fact that a degree of longitude covers less ground the further you are from the equator), then applies the shoelace formula, a standard method for finding the area of any simple polygon from its corner coordinates. This calculates the area of the outline you traced. Real-world accuracy depends on the imagery and how closely your points follow the lawn edge.
An area that's too small understates how much product or water a job needs, leaving the treatment or watering run short of the label rate across the missed ground. An area that's too large overstates it, pushing more product or water onto the lawn than the label calls for. Both come from the same root cause: a guessed or roughly-taped area instead of a measured one.
No. Block size includes the house, driveway, shed and garden beds. This tool measures only the area you trace, so trace the lawn itself for a number that matches what a product label or seasonal plan needs.
No. It's free, with no sign-up and no login.
No. The map and the area calculation run entirely in your browser. Nothing you search or trace is stored, logged or sent to LawnSuite.
The map opens zoomed out to the whole country, where a few pixels of on-screen tracing cover a wildly unrealistic area. Search your address (or zoom in manually) and tracing switches on once the map is close enough that a click represents a sensible distance on the ground.
Yes. Trace as many separate areas as you need. Each one is listed with its own size, and they're added into a running total.
The area maths uses the coordinates you trace. The main real-world limit is how precisely you trace the edge by eye, and how current or clear the satellite imagery is for your address, the same limits that apply to reading any aerial photo.
Copy the total before leaving, then create a Free account. During lawn setup, choose Type it and enter your area in m². LawnSuite saves that zone area for later calculations. The outline you traced here does not transfer to your account.
