How to measure lawn square footage online

Trace irregular or separated lawn sections, leave out non-lawn surfaces, and check unclear edges before using the total.

By Measure The Lawn Updated August 13, 2026

Use lawn area, not lot size.

Search the address and trace each grass section on the satellite map. Leave out the house, driveway, patio, pool, and planting beds, then use the combined square footage.

Measure your lawn

Choose what belongs in the measurement

A lot size includes more than lawn. For seed, sod, treatments, or mowing, measure only the area that receives the product or service.

Trace every grass section for a whole-lawn job. For a patch repair, trace only the area receiving seed or sod. The useful boundary is the work—not the property line.

The outlined lawn is smaller than the lot because buildings, hard surfaces, and beds are excluded.

Trace curves, separate sections, and exclusions

Use Rectangle for a simple box-shaped section. Use Freeform when the edge curves, changes direction, or wraps around another surface. Place points where the boundary meaningfully turns.

Measure front, side, and back lawns separately when a driveway or building divides them. The map combines included measurements. Cut out a pool, patio, bed, or structure that sits inside a larger measurement.

Use enough points to follow the visible boundary without tracing every small bend.

Check unclear imagery before using the total

Review the measurement at close zoom. Satellite imagery can be old, hidden by trees or shadows, or assembled from images captured on different dates.

For an expensive order or a property that has changed, confirm the uncertain section with a tape, measuring wheel, supplier visit, or another onsite check.

  • Confirm the address and property before drawing.
  • Keep every point off roofs, driveways, beds, pools, and neighboring lawns.
  • Include every front, side, and back section that belongs in the job.
  • Recheck edges hidden by trees or shadows with a known dimension or onsite measurement.

Confirm important boundaries onsite.

The map supports material and service planning. Confirm legal boundaries and current site conditions through the appropriate onsite source when they affect the work.
