How the yard area calculator works

Rectangular yard mode:
The calculator multiplies yard length by yard width to estimate square footage, acres, perimeter, fence length, materials, and cost.

Multiple areas mode:
The calculator multiplies one yard section by the number of same-size yard areas.

Known area mode:
The calculator starts from your known yard area and estimates usable area, lawn area, garden area, sod, seed, mulch, topsoil, and water.

Circular yard mode:
The calculator uses diameter to estimate circular yard area and boundary length.

Why use a yard area calculator?

Frequently asked questions

How do I calculate yard square footage?

Multiply yard length by yard width. For example, an 80 foot by 50 foot yard has 4,000 square feet before subtracting excluded areas.

What should I subtract from yard area?

Subtract house footprint, driveway, patio, deck, shed, sidewalks, garden beds, pools, and other areas that should not be counted as usable yard or lawn.

How do I estimate sod for a yard?

Use the lawn area with waste, then divide by the coverage of one sod roll or piece. Add extra for curves, cuts, edges, and damaged pieces.

How do I estimate fence length for a yard?

Use the yard perimeter, choose how many sides need fencing, and subtract gate openings or access openings.

Is this yard calculator exact?

No. It is an estimate. Actual yard area can vary by irregular shapes, slopes, property lines, buildings, patios, beds, sidewalks, fences, and measured exclusions.
