How to measure yard or lawn square footage from satellite imagery

Set the area unit to Square Feet (ft²), trace the lawn's corners on the Satellite map with Measure > Measure Area, read Area. A lawn with sides of 65.7 ft and 56.5 ft comes out at 3,708.7 ft², much faster than dragging a wheel around the grass.

Why you need the square footage

Seed, sod, fertilizer, weed control, mulch, lawn-care quotes — all priced by the area covered. A tape does fine on a plain rectangle. An L-shaped backyard with beds cut into it and a curve along the patio is a different story, and that's where tracing on imagery wins.

How to measure lawn square footage with LandMeasure

  1. Open Settings > Units and set Area to Square Feet (ft²) and Distance to Feet (ft).
  2. On the Map tab, tap the map button at the top right and choose Satellite.
  3. Zoom in as far as the imagery allows, so the lawn fills the screen.
  4. Tap Measure > Measure Area and tap each corner of the lawn edge in order. On curved beds, add a tap every few feet along the curve.
  5. Drag any handle that sits off the edge. Long-press a side to insert a corner you missed.
  6. Read Area, then tap the green checkmark to save it in the project.

Why you should not walk a small yard

Walk Mode runs on phone GPS, which is off by a few meters no matter what you do. That's nothing on a big field; on a small plot it eats the whole result. At ±4 m reported, the panel's GPS margin for this same lawn is ± 1,602.9 ft² — nearly half of the 3,708.7 ft² it measured.

Tapping corners on zoomed-in imagery sidesteps that GPS error entirely. Your accuracy then rides on how sharp the imagery is and how careful your tap was, neither of which the app can see — so ignore the GPS margin line on a tapped lawn, it isn't describing what actually limits you.

Front yard, backyard and the house in between

  • No subtract tool, no holes cut in a shape — trace around the house, beds and driveway rather than the whole lot.
  • One measurement per project on the free tier. Front yard and backyard want two separate projects, or LandMeasure Pro to keep both together under Total Area.
  • Shade trees swallow the lawn edge on imagery. Tap where the edge would logically sit, or just grab a tape for that one stretch.

Questions and answers

How do I measure my yard square footage without a tape?
Trace it on satellite imagery with the area unit set to square feet. Zoom in close and tap every corner in order — that's the whole method.
Can I see the result in square meters too?
Switch Area in Settings > Units and the saved lawn redraws in the new unit — 3,708.7 ft² becomes 344.5 m², same shape, no re-measuring.
Does it subtract the house or flower beds?
It doesn't. Trace only the grass, or measure the house and beds separately and subtract them by hand.
