A tape measure works fine if your lawn is a perfect rectangle. The problem: almost no lawn is. You have curved beds, a kidney-shaped patio, an L-shaped strip down the side of the house, maybe a peninsula of grass cutting between the driveway and the front walk. A tape measure of an irregular lawn is typically ±5–10% off. That's the difference between buying one bag of fertilizer too few or three bags too many.
A satellite lawn measuring tool sees the whole shape from overhead and calculates the area of any polygon — odd shapes, multiple sections, holes for flower beds — in seconds. It also handles sloped lawns better, because the geometry is calculated, not paced. That's exactly how our free measure my lawn tool works.

Type your address. Satellite imagery loads automatically and zooms to your property.
Outline the lawn. Click points around the edge of your grass. Snap to the parcel boundary if you have one.
Subtract non-grass areas. Click around buildings, driveways, flower beds, pools, patios. The tool cuts each one out of the lawn.
Get your number. Final lawn square footage appears instantly. Optionally generate a personalized care calendar with exact product quantities for your size.

Start Measuring — FreeFertilizer bags list coverage in square feet. If you guess your lawn size, you guess wrong — and either burn your grass with too much nitrogen or starve it with too little. See how much fertilizer you actually need for the math.
Seeding rates depend on grass type and whether you're overseeding or starting from scratch. Without a measurement, you're flying blind.
Most lawn products sell coverage by area. Once you know your number, our pre-emergent timing guide tells you exactly when to apply.
After measuring, MeasureLawn builds you a free month-by-month plan tailored to your grass type, climate zone, and lawn size — with the exact product quantities (no "1 bag should do it" nonsense).
Mowable grass area is more useful than your whole lot size when comparing a walk-behind, lawn tractor, zero-turn or robot. Start with a rough size, then consider terrain and how you prefer to mow.

How accurate is an online lawn measuring tool?
MeasureLawn measures the shape you trace on current satellite imagery. It's a close estimate: close enough to buy seed and fertilizer by the bag, and accuracy depends on the imagery and how carefully you trace. A tape measure on an irregular lawn is harder to get right, because you have to break the yard into rectangles.
Is the lawn measuring tool really free?
Yes. No sign-up, no app, no trial, no paywall. We make money through optional Amazon affiliate links inside the lawn care plan you can generate after measuring.
Do I need to download an app?
No. The tool runs in any modern browser on phone, tablet, or desktop.
Can I subtract my driveway, beds, and pool?
Yes. After drawing your overall property outline, the tool walks you through carving out non-grass areas — buildings, driveways, sidewalks, patios, decking, flower beds, pools, and anything else paved or planted.
How long does measuring take?
Under 2 minutes for most lawns.
Will I be asked for my email?
No. Measuring works without an account. An optional account lets you save and reopen plans, but is never required to use the tool.
