Calculate lawn square footage, acres, sod rolls, grass seed, fertilizer, lime, topsoil, mowing time, irrigation water, and estimated lawn project cost.
Rectangular lawn mode:
The calculator multiplies lawn length by lawn width to estimate square footage, perimeter, sod, seed, fertilizer, water, and cost.
Multiple areas mode:
The calculator multiplies one lawn area by the number of same-size lawn sections.
Known area mode:
The calculator starts from your known lawn area and estimates sod rolls, seed, fertilizer, lime, topsoil, water, and mowing time.
Circular lawn mode:
The calculator uses diameter to estimate circular lawn area, perimeter, sod, seed, and water needs.
A lawn area calculator helps estimate square footage for sod, grass seed, fertilizer, lime, topsoil, irrigation, mowing, lawn repair, and landscaping projects.
It can help calculate lawn square feet, acres, square yards, square meters, sod rolls, grass seed, fertilizer, lime, topsoil volume, water gallons, mowing time, and project cost.
Your result shows gross lawn area, excluded area, net lawn area, area with waste, acres, square yards, square meters, sod rolls, grass seed, fertilizer, lime, topsoil volume, water needed, mowing time, and estimated cost.
Multiply lawn length by lawn width. For example, a 60 foot by 40 foot lawn has 2,400 square feet.
Divide the lawn area with waste by the coverage of one sod roll or piece. Add extra for cuts, curves, edges, and waste.
Divide lawn square footage by 1,000, then multiply by the seeding rate listed on the seed bag.
One inch of water over one square foot is about 0.623 gallons. Multiply lawn square footage by 0.623 for a 1 inch watering estimate.
No. It is an estimate. Actual lawn needs vary by shape, slopes, excluded areas, soil condition, sod size, seed type, fertilizer rate, irrigation efficiency, mower overlap, and waste.
