Sod calculator
A 1,000 sq ft lawn with 10% waste needs 1,100 sq ft of turf: 110 rolls of 10 sq ft, which is 3 pallets at 50 rolls each. Rolls and pallets are both rounded up so the last strip is covered. Free in your browser.

Ordering sod without a clear material count is how projects run short on the last strip or overbuy whole pallets that never leave the driveway. This sod calculator takes the measured lawn area, the coverage of one commercial roll, and a waste allowance for cuts and curves, then returns the number of rolls you need and how many pallets that becomes at a stated rolls-per-pallet packing.
What the calculator multiplies and why waste matters
Live turf is sold by the roll or the pallet, not by the exact square foot of your sketch. You measure or estimate the plantable area in square feet or square meters, then state how much ground one roll covers when laid flat — a common North American roll is about two by five feet for ten square feet, while metric suppliers publish their own coverage on the product tag.
Raw area divided by roll coverage under-orders almost every real yard: edges against sidewalks, curved beds, tree rings, and imperfect roll joints force cut-outs that cannot be reused as full rectangles. A waste allowance — often five to fifteen percent — scales the measured area upward before the roll count is rounded up, so the last short edge still has material.
This capability multiplies area by one plus waste percent over one hundred, divides by roll coverage, and applies a ceiling so partial rolls become whole rolls you can actually purchase.
Inputs, units, and the pallet conversion
The unit field is a label only: the service does not convert between square feet and square meters, so keep area and roll coverage consistent. Use leftover as a sanity check that you are not over-ordering by multiple full pallets when a smaller waste percent would still cover seams. Landscape crews can stick to default waste and packing, while procurement teams can pin supplier-specific roll coverage and pallet counts for repeatable purchase orders across many lots.
What you can do with it
Homeowner lawn renovation orders
Convert a measured backyard area and the roll size on the product label into a roll count with waste so a weekend install does not run short on the final edge.
Landscaper multi-lot estimates
Batch the same waste and pallet packing across many properties to generate consistent material lists for purchase orders and crew tickets.
Garden-center counter quotes
Let staff enter customer square footage and local roll coverage to quote rolls or whole pallets without a fragile spreadsheet.
FAQ
How does the sod calculator count rolls?
It multiplies lawn area by one plus the waste percent over one hundred, divides by the coverage of one roll, and rounds up to the next whole roll so you never order a fractional roll.
What if my area is zero or negative?
Area must be a positive number greater than zero; empty or non-numeric values are also rejected without charge.
Does unit convert square feet to square meters?
No. The unit field is only a label (sqft or sqm).
How much waste should I add when ordering sod?
Usually between 5 and 15%, and the calculator uses 10% unless you set another value. Edges against sidewalks, curved beds, tree rings and imperfect joints force cut-outs that cannot be reused as full rolls.
How do I work out sod for an irregular lawn?
Work out the area of the shape separately first, then enter that single figure. The calculator focuses on turning a known area into rolls and pallets, so run it again if the crew measures a different area after removing the old turf.

For developers — API access
Everything on this page is available programmatically. This section is for teams who want to wire it into their own systems; everyone else can just use the tool above.
API endpoint
Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

Technical notes
The math is deterministic and identical in the free browser tool and the paid API, so quotes, purchase orders, and job tickets share one figure instead of three conflicting spreadsheet formulas.
Inputs, units, and the pallet conversion
Send a positive area, a positive roll_coverage in the same unit system, an optional waste_percent defaulting to ten, an optional rolls_per_pallet defaulting to fifty, and an optional unit label of sqft or sqm. Non-positive area is rejected with invalid_input and is not charged. The response echoes the effective area after waste, the integer roll count, the pallet count as the ceiling of rolls divided by rolls per pallet, the total coverage those rolls represent, and leftover coverage above the effective need.
How to run it free, by API, and in a materials pipeline
Pair the roll and pallet counts with your supplier unit price to produce a line item, then re-run when the client changes bed shapes or when the yard crew measures a different area after removing old turf. For irregular polygons, compute area with a separate geometry step first, then pass the resulting number here; this capability intentionally focuses on the material packing problem rather than survey-grade area measurement. Use the in-browser tool for a single backyard estimate before you leave for the garden center, or call the same JSON contract from an estimating app, CRM, or batch job that prices dozens of lawn renovations. The published API price is $0.002 per successful item; failed validation does not consume prepaid balance.
Technical questions
How are pallets calculated?
Pallets equal the ceiling of rolls divided by rolls_per_pallet (default fifty). Set rolls_per_pallet to match your supplier’s packing so the pallet count matches what you can order.
Is this free, and what does the API cost?
The in-browser tool is free and runs locally. API usage is prepaid KIT balance at $0.002 per successful request. Invalid input fails without charge.
