Garden calculator
Sod Calculator
Calculate sod pieces and full pallets from your lawn area and the coverage your supplier actually sells.
Planning estimate, not a contractor quote. Review the assumptions and replace presets with local prices when available.
Method
How this calculator works
Measure the area that will receive new sod, excluding beds, paths, and buildings. A pallet is not a universal area: enter the coverage of one roll or piece and the number supplied per pallet. The result separates the pieces needed from the whole-pallet order, which is useful when a supplier offers partial pallets.
Adjusted area = length × width × (1 + allowance ÷ 100). Pieces = ceil(adjusted area ÷ piece coverage). Pallets = ceil(pieces ÷ pieces per pallet).
Worked example
A realistic starting point
A 20 × 10 ft lawn with 10% allowance needs 220 ft². At 10 ft² per piece it needs 22 pieces. A 50-piece pallet provides 500 ft², so a one-pallet order contains substantially more than this small lawn requires.
What changes the answer
Factors worth checking
Verify the pallet
Confirm actual pieces and coverage with the sod farm. A retail pallet description can differ between farms or grass products.
Cuts and shape
Curved beds and narrow strips produce different cutting losses from a simple rectangle. Treat the allowance as a planning choice rather than a guaranteed percentage.
Compare supply terms
The price output uses full pallets. Ask whether individual pieces are available and include delivery, preparation, installation, and watering arrangements in your complete budget.
Common questions
Sod FAQ
How much area does a pallet cover?
Multiply the entered piece coverage by pieces per pallet. The calculator does not assume all pallets have the same coverage.
Can I use rolls instead of slabs?
Yes. Enter the coverage of one physical roll as piece coverage and the actual rolls per pallet.
Why does purchased coverage exceed my lawn?
Both cuts and pallet rounding increase the purchase. Compare partial-pallet availability before buying excessive surplus.
