Lawn Size Calculator

Convert measurements in feet to mowable square feet, acres, and square yards. Useful for preparing estimates and planning routine mowing jobs.

Measure your lawn

For L-shaped yards, enter each rectangle separately. Subtract patios, buildings, planting beds, and other non-mowable areas. For irregular shapes, the result is an approximation.

How to estimate lawn area in square feet

Measure the length and width of each rectangular section in feet. Multiply the two measurements to get square feet, add any second section, and subtract non-mowable space such as a driveway, building, or flower beds.

Formula: (length × width) + (second length × second width) − exclusions. One acre equals exactly 43,560 square feet; one square yard equals 9 square feet.

50 ft × 60 ft3,000 sq ft

When the estimate may be inaccurate

Hills, irregular lot lines, curved planting beds, inaccessible corners, and areas covered by landscaping will affect the actual mowable area. For important bids, take on-site measurements or verify your dimensions using a suitable mapping service.
