How to Measure Your Lawn

Knowing your lawn's exact square footage is essential for applying the right amount of fertiliser, seed, and weed control. Too much wastes money and can damage your grass. Too little won't work. Here's how to get it right.

The Easy Way: Use Our Free Lawn Calculator

Instead of walking around with a tape measure, use our free lawn area calculator to trace your lawn on satellite imagery from your computer or phone. Measure Lawn uses Google Maps satellite imagery so you can see your actual property from above and draw precisely around your grass areas.

Step 1: Find Your Property

Type your address into the search bar. The map zooms to your property with satellite imagery showing your house, lawn, driveway, and landscaping from above.

Step 2: Trace Your Lawn Boundary

Click the Draw tool and trace around the edge of your entire property. Include all grass areas. The tool calculates the total enclosed area automatically as you draw.

Step 3: Exclude Non-Grass Areas

Mark your house, driveway, flower beds, patio, and any other areas that aren't grass. These get subtracted from the total, giving you the exact square footage of your lawn only.

Step 4: Get Your Measurement

Your lawn size in square feet appears instantly. This number is used to calculate exactly how much fertiliser, seed, pre-emergent, and other products you need — no more guessing.

Why Accurate Measurement Matters

  • Fertiliser: Too much burns your lawn. Too little has no effect. Exact square footage means exact quantities.
  • Seed: Overseeding rates are calculated per 1,000 sq ft. Wrong measurements mean patchy results.
  • Pre-emergent: Coverage gaps let weeds through. You need even coverage across every square foot.
  • Cost savings: Buying the right number of bags instead of guessing saves money every season.
