Include only treated turf
Trace front, side, and back lawns separately instead of measuring the entire lot or drawing across the house.
How to measure lawn square footage
Measure lawn square footage without treating the yard like one rectangle.
Most lawns wrap around beds, pavement, trees, and buildings. A useful measurement separates those sections, excludes surfaces that will not receive material, and preserves the total in units you can use for pricing.

Handle curves and narrow strips
Place additional points where the boundary changes direction and fewer points along straight edges.
Use the result immediately
Send the combined area into the sod, grass seed, topsoil, or fertilizer calculator without retyping it.
Connected workflow
Measure a lawn online in four steps
- 01
Find the property
Search the street address, switch to satellite imagery, and zoom until lawn edges and excluded surfaces are distinguishable.
- 02
Outline the first section
Click around one continuous grass area, following the visible outer edge while leaving out beds, pavement, structures, and pools.
- 03
Add the remaining sections
Finish each separate lawn independently. Measure side strips, islands, and backyard sections as additional shapes so the map can combine them.
- 04
Review and apply the area
Adjust misplaced points, compare square feet and square yards, then open the material calculator that matches the planned work.
What to know
Manual formula or satellite outline?
For a rectangle, multiply length by width. For a triangle, multiply base by height and divide by two. A 60-by-40-foot rectangle is 2,400 square feet; subtracting a 20-by-20-foot patio leaves 2,000 square feet of lawn.
A satellite outline is faster for curved or separated lawns, but it remains a planning estimate. Trees, shadows, roof overhangs, slopes, image alignment, and unclear borders can affect the result, so verify important dimensions before ordering or applying material.
Common questions
Questions contractors ask
Can I measure my lawn online for free?
Yes. YardMeasure lets you search an address, outline multiple visible lawn sections, and view their combined square footage without creating an account.
Should I subtract garden beds and the driveway?
Yes when those surfaces will not receive the planned material or treatment. Outline lawn sections separately rather than including excluded areas and trying to estimate them later.
Is lawn square footage the same as lot size?
No. Lot size includes the full parcel, while lawn square footage should include only the grass or proposed turf area relevant to the project.
