/// Lawn area and roll count

Sod Calculator

Use the sod calculator to multiply lawn length by width, apply the cutting allowance you choose, divide by supplier coverage per roll or slab, and round up to whole units. Measure irregular lawn sections separately. Sod dimensions, pallet quantities, seams, grade, irrigation, soil preparation, delivery limits, installation timing, and retained repair pieces need separate checks.

/// Formula & field notes

How this sod estimate works

FormulaSod units = lawn area × (1 + waste %) ÷ supplier coverage per roll or slab, rounded up.

Worked example

A 50 ft × 20 ft lawn is 1,000 ft²; with 5% waste and 10 ft² rolls, the order quantity is 105 rolls.

/// Common questions

Sod calculator FAQ

What should I verify before ordering sod?

Confirm field dimensions and supplier roll or slab coverage and lawn shape against the exact product or supplier information. ProjectQty shows the assumptions so you can replace planning defaults before ordering whole rolls or slabs.

How does waste affect the sod estimate?

Waste is applied after the base geometry is calculated and before discrete packages or pieces are rounded up. Use a higher allowance for complex layouts, cuts, pattern matching, breakage, or uncertain field dimensions.

Is this sod result a professional design?

No. It is a quantity-planning result. Species, climate, soil preparation, irrigation, delivery timing, and installation practices require local supplier guidance.
