Acreage Calculator

Multiply length × width in feet to get square footage, then divide by 43,560 (sq ft per acre). For a rectangular 200 ft × 300 ft lot: 200 × 300 = 60,000 sq ft ÷ 43,560 = 1.38 acres. For irregular shapes, break into rectangles, calculate each, sum, and divide by 43,560. For circular areas: Area = π × r², then divide by 43,560.

One acre equals exactly 43,560 square feet. Common comparisons: 1 acre ≈ 208.7 ft × 208.7 ft (square), 1 acre ≈ 90% of a football field (without end zones), 1 acre ≈ 4,840 square yards, 1 acre ≈ 0.4047 hectares. An acre was originally defined as the area a team of oxen could plow in one day.

Google Maps: Right-click on start point, select Measure distance, click points around property boundary, finish at start point. The perimeter shows total distance. Google Earth Pro (free): Draw polygon around property, right-click and check Properties > Measurements for area in acres. Mobile apps: GPS Fields Area Measure, Geo Area Calculator. Always verify with professional survey for legal boundaries.

A standard American football field (including end zones) is about 1.32 acres. Field dimensions: 360 ft × 160 ft = 57,600 sq ft ÷ 43,560 = 1.32 acres. Without end zones: 300 ft × 160 ft = 48,000 sq ft ÷ 43,560 = 1.10 acres. Soccer fields vary from 1.5-2.5 acres depending on regulation size. Baseball fields need 2-5 acres for the full diamond.

A half-acre is 21,780 sq ft (43,560 ÷ 2). Typical dimensions: 100 ft × 217.8 ft, or 150 ft × 145.2 ft, or a square roughly 147.6 ft × 147.6 ft. Quarter-acre: 10,890 sq ft (about 104 ft × 104 ft square). One-acre square: roughly 208.7 ft each side. Suburban lots typically range from 1/4 to 1/2 acre.
