Sod Calculator
Measure the lawn the way it actually is: add a row for every rectangle and every circle, then add a second list for the patio, the drive, the pond or a planting bed, and those come off the total. Set the waste allowance you want and type what one roll covers, from your own supplier's quote, because that figure is the reason two sod calculators give two different answers for one lawn and it is a field here rather than a number chosen for you. The answer comes back as four separate figures you can check a quote against: the lawn area, the area once your waste allowance is added, the rolls rounded up, and, once you give the rolls per pallet, the pallets, shown as full pallets plus the loose rolls on top and again as whole pallets for a farm that sells pallets only. Add a price per roll or per pallet and it totals the order. Feet, yards or metres, and every figure the count used is printed underneath it. Use separate non-overlapping parts and exclusions inside them: this page does not detect overlapping rows or trace a map. Circle quantities are approximate; a whole-roll range marks an uncertain boundary. The complete selectable calculation retains exact values, circle bounds and supplied prices.
What this count assumed
- Roll coverage is exactly the supplied 10 square ft; no supplier size is assumed.
- Your 10 percent allowance is applied to the combined net area before rounding rolls up.
- Rectangles are exact rational arithmetic. Circle contributions retain a symbolic coefficient of π through additions and exclusions; decimal quantities use certified 100-place bounds. A count range marks a bound crossing a whole-roll boundary.
- Row areas must describe separate non-overlapping lawn parts and exclusions inside them. This arithmetic does not locate overlaps, trace maps, assess suitability or plan cuts.
- No price supplied.
- Prices use the supplied currency and exclude tax, delivery, installation, minimum orders and supplier availability. This is quantity and price arithmetic, not a quote.
The fields open on a worked example: a 40 ft by 25 ft lawn, rolls that cover 10 sq ft and 45 rolls to a pallet. Those are the example's numbers, not your supplier's. Take the coverage and the pallet size off your own quote and type them over, because they vary from farm to farm: clear the coverage and this page asks you for it rather than filling one in.
Complete selectable calculation
Unit changes preserve dimensions and roll coverage as exact decimals or fractions. ≈ marks approximate circle quantities; … marks an abbreviated large preview. The complete calculation retains all digits and circle bounds. Measure separate non-overlapping parts and exclusions inside them; this page does not detect overlaps or trace maps.
Common questions
- How much does a pallet of sod cover?
- Multiply the coverage per roll by the rolls per pallet supplied on your quote. For example, 45 rolls at 10 square feet each cover 450 square feet; those are example inputs, not a standard package. Enter both figures here to count your lawn as full pallets plus loose rolls and as whole pallets only. Clear rolls per pallet to leave pallet counts out. Clear roll coverage and the page asks for it, rather than inventing a supplier's roll size.
- How much waste should I allow?
- The allowance is your supplied percentage, not a cutting recommendation. The field accepts 0 to 100 percent. A 1,000 square foot lawn at 10 percent becomes 1,100 square feet before the one final upward roll rounding, giving 110 rolls at 10 square feet each. Zero allowance counts the bare area rounded up. The tool cannot measure offcuts, damage or the layout of rolls; choose the allowance for your measured job and supplier.
- How do I measure an irregular lawn?
- Represent separate non-overlapping rectangular and circular parts with rows, then subtract non-overlapping exclusions inside those parts. A 40 by 15 foot rectangle plus a 40 by 10 foot rectangle totals 1,000 square feet. A circle row uses its full measured diameter. It does not represent a semicircle, trace a boundary, locate overlaps or measure a map. A 60 by 30 foot rectangle minus a 12 by 10 foot patio leaves 1,680 square feet. Exclusions that remove all or more of the lawn are refused. Circle contributions retain symbolic pi and bounded approximations through additions and subtraction.
- Should I order by the roll or by the pallet?
- Use the order basis on your supplier's quote. The tool shows whole rolls, full pallets plus the loose-roll remainder and whole pallets only. At 45 rolls per pallet, 110 rolls is 2 full pallets and 20 loose rolls, or 3 whole pallets. With both prices supplied, cost uses full pallets at the pallet price and loose rolls at the roll price. With only a pallet price it buys whole pallets; with only a roll price it prices all rolls. This is supplied price arithmetic, excluding delivery, tax, installation, minimum orders and availability.
- How many rolls of sod do I need for 1,000 square feet?
- With rolls that cover 10 square feet each and a 10 percent waste allowance, 1,000 square feet is 1,100 square feet ordered, which is 110 rolls. At 5 percent waste it is 105 rolls, and with no allowance at all 100. Change the coverage and the count moves with it: the same lawn measured in metres, at 1.5 square metres a roll, is 69 rolls, because 1,000 square feet is 92.9 square metres, 10 percent takes it to 102.2, and that over 1.5 rounds up. Rolls are always rounded up, because a supplier does not sell a tenth of one, and an area that lands exactly on a roll boundary is not pushed up an extra roll.
- Does it work in metres?
- Yes. Feet, yards and metres are supported, with roll coverage in square feet, square yards or square metres respectively. Changing units converts dimensions and coverage without rounding the physical question. An exact terminating decimal or complete fraction is retained in each converted field. The stage also prints the net lawn in square feet or square metres. Circle decimal quantities use certified 100-place pi bounds; a range of rolls or pallets means the bounds cross a whole-count boundary. Complete values and the working are in the selectable calculation.
- What does this calculator not cover?
- It counts material for an area and stops there. It does not tell you how to prepare the ground, how much topsoil or grading a site needs, what to do about drainage or irrigation, which grass to lay or when to lay it. It cannot see the site either: how an awkward shape cuts, how much a delivery is short, and what your supplier's actual roll measures are all outside it, which is why the coverage is a field and the waste is an allowance you set. For the soil under the lawn, the soil calculator works out a volume, and the area calculator handles shapes this page does not.
- Is anything uploaded, and does it cost anything?
- The arithmetic runs in your browser and the core calculation needs no account. Valid deliberate changes save only edited fields and safely matched rows into the latest usable browser draft. Opening defaults, restored work or a worked example does not rewrite saved data. Invalid drafts stay on screen while the previous save is kept; malformed or newer records remain until you explicitly forget them. Forget saved draft removes that local record; Back to the example changes the current fields. Input dimensions, prices and calculation text are not sent in measurement events. The page can measure a completed changed calculation or current successful copy through the site's privacy-aware measurement controls.
Exact arithmetic for rectangles and supplied coverage, with rolls and pallets rounded up. Circles retain symbolic pi and certified bounds; a count range marks an uncertain boundary. It cannot know your supplier's roll size or how a shape cuts: use your quote and the allowance you chose. Prices exclude delivery, tax and installation.
