Inputs
- Lawn length: Finished lawn length Default: 30.

How this calculator works
This calculator turns lawn area, supplier roll coverage and a visible cutting allowance into a whole-roll sod order.
- Measure the finished lawn area and split irregular areas into rectangles where practical.
- Enter the coverage printed by the local sod supplier for one roll or pallet unit.
- Apply a visible allowance for cuts around curves, beds and hardscape before ordering whole rolls.
Worked example: Example: a 30 ft × 20 ft lawn is 600 ft². With 10% waste and 10 ft² rolls, the calculation rounds up to 66 rolls.
Assumptions and limitations
- Roll coverage must match the selected supplier product.
- Waste is applied before whole-roll rounding.
- Irregular lawn areas should be divided into simple measured sections before totaling.
Common questions
- Are all sod rolls the same size?
- No. Supplier coverage varies, so replace the default with the stated coverage for the product you will purchase.
- Does this include soil preparation?
- No. Grading, topsoil, irrigation, drainage and installation requirements need separate review.
