How many sod rolls or slabs cover my measured lawn?
| Planning input | Calculation role | Landscape check |
|---|---|---|
| Lawn dimensions | Create measured installation area | Separate irregular sections |
| Supplier unit coverage | Converts area into sod pieces | Use the actual roll or slab |
| Cutting allowance | Adds pieces before whole-unit rounding | Reflect edges and layout |
Lawn-area conversion preserves the same physical surface through the exact 0.3048-meter international foot.

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.

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.
