How to Calculate Acreage
Calculating acreage is straightforward for rectangular lots: multiply the length by the width to get the total area in square feet, then divide by 43,560 (the number of square feet in one acre). For example, a lot that measures 200 feet by 300 feet is 60,000 square feet, or about 1.38 acres.
If you don't know your property's dimensions, King County and other local assessor websites provide online parcel viewers where you can look up your lot's exact size. Your property deed or title report will also list the acreage. For oddly shaped lots, irregular boundaries, or properties with easements, a professional land survey is recommended for the most accurate measurement.
Once you know your acreage, use our cost estimator to get an estimate for clearing your property. Whether you have a small residential lot or a multi-acre parcel, knowing the exact size helps us provide an accurate quote for your land clearing project.
