Lawn Square Foot
Calculator — Yard Area Tool

Measure yard length and width in feet, multiply together, then subtract the house, driveway, and garden bed areas. A 100x60 ft yard minus a 1,500 sq ft house footprint and 400 sq ft driveway = 4,100 sq ft of lawn.

Most grass seed needs 2-4 lbs per 1,000 sq ft for new lawns and 1-2 lbs per 1,000 sq ft for overseeding. A 5,000 sq ft lawn needs 10-20 lbs of seed for a new installation.

Most fertilizers cover 5,000-15,000 sq ft per bag. Check the bag label for coverage area and divide your lawn square footage by that number to determine how many bags to buy.

The average American lawn is about 5,000-10,000 square feet. Small urban yards may be 1,000-3,000 sq ft, while suburban lots often have 8,000-15,000 sq ft of grass.

Calculate lawn area in square feet and order 5% extra sod for waste. Sod is sold in rolls (typically 9 sq ft each) or pallets (450 sq ft). A 5,000 sq ft lawn needs about 556 rolls or 11.7 pallets.

Divide square feet by 43,560 to get acres. A 10,000 sq ft lawn is 0.23 acres. A quarter-acre lot (10,890 sq ft) is a common suburban yard size.
