Sod Calculator
Measure your lawn, add a waste allowance and find out how much sod to order: square feet, pieces, pallets and total cost.
🌱 What is a Sod Calculator?
Sod, also called turf, is grass grown at a farm and harvested with a thin layer of soil and root still attached, so it can be laid straight onto prepared ground to make an instant lawn. A sod calculator turns the measurements of the area you want to cover into the quantity you actually have to order: the net lawn area, the area once a waste allowance is added, the number of individual pieces or rolls, the number of whole pallets and the resulting cost. This calculator handles rectangular, circular and triangular areas, so an irregular lawn can be split into sections and totalled up.
The reason this matters is that sod is not sold by the exact square foot. It is cut into fixed-size pieces, stacked onto pallets with a fixed coverage, and delivered by the pallet. Ordering 600 square feet of lawn does not mean buying 600 square feet of sod: you buy whole pieces, from whole pallets, with enough spare to cover the offcuts you create trimming around beds, paths and trees. Running short is the expensive failure mode, because a second delivery of half a pallet can cost as much in freight as the sod itself, and the pieces you already laid will have started drying at the seams by the time it arrives.
The most common measuring mistake is fitting one big rectangle around a lawn that is not rectangular. A lawn with a curved bed along one side is not the rectangle that encloses it, and treating it as one either wastes money or, if you eyeball a reduction, leaves you short. The right approach is to break the shape into rectangles, circles and triangles, measure each one, run each through the calculator and add the areas. The second common mistake is skipping the waste allowance altogether: every curve and every corner turns a full piece into an offcut that usually cannot be reused, which is why 5 to 15 percent extra is standard practice rather than padding.
Beyond the order quantity, this page shows the two things that most often change a decision. The chart plots pallets needed against lawn area, and because pallets are sold whole it is a staircase, so you can see immediately whether you are just over a step and could drop a whole pallet by trimming the area or the waste allowance slightly. The table lists what you would order and pay at waste allowances from 0 to 20 percent, which makes the real cost of that safety margin explicit. If you are weighing sod against starting from seed, the Grass Seed Calculator covers the other side of that decision.

💡 Example Calculations
Example 1 — Standard Rectangular Back Lawn
30 ft × 20 ft lawn, 10% waste, 10 sq ft rolls, 450 sq ft pallets at 0.45 per sq ft
Example 2 — Circular Lawn Around a Feature Tree
24 ft diameter circle, 10% waste, 10 sq ft rolls, 450 sq ft pallets at 0.45 per sq ft
Example 3 — Triangular Corner Section
36 ft base, 22 ft height, 15% waste for the awkward corners, 0.50 per sq ft
Example 4 — Long Front Strip, Simple Shape
45 ft × 18 ft strip with a straight edge, so only a 5% waste allowance
❓ Frequently Asked Questions
🔗 Related Calculators
How much sod do I need for my lawn?
Measure the lawn area in square feet, then add a waste allowance for cuts and curves. A 30 by 20 foot lawn is 600 square feet, and with a 10 percent allowance you would order 660 square feet, which is 66 pieces at 10 square feet each, or 2 pallets at 450 square feet.
How do I calculate square footage for sod?
For a rectangle multiply length by width. For a circle use pi divided by 4 times the diameter squared. For a triangle use half the base times the perpendicular height. Break an irregular lawn into these shapes, calculate each and add the results.
How many square feet are in a pallet of sod?
Most pallets cover 400 to 500 square feet, with 450 square feet being a common figure. Some suppliers sell 600 square foot pallets. Always confirm the coverage with your supplier and enter their number, because pallets are sold whole and the rounding matters.
How big is one piece of sod?
A standard North American slab is about 16 by 24 inches, which is 2.67 square feet. Rolls are commonly 2 feet by 5 feet, which is 10 square feet, and big rolls used on large sites can cover far more. Enter your supplier's coverage per piece.
How much waste should I add when ordering sod?
Five to 10 percent for a simple rectangle, 10 to 15 percent for lawns with curves, garden beds, trees or awkward corners. The waste covers offcuts that cannot be reused, damaged edges on the pallet and the pieces you trim to fit along a boundary.
How do I convert square feet of sod to square yards?
Divide by 9, since a square yard is 3 feet by 3 feet. A 600 square foot lawn is 66.67 square yards. To convert to square metres, multiply square feet by 0.0929, so 600 square feet is 55.74 square metres.
How much does sod cost per square foot?
Typical supply-only pricing runs about 0.30 to 0.80 per square foot for common turf varieties, with premium and specialty grasses higher. Installation labour, soil preparation and delivery are usually charged separately, so this figure covers the sod itself.
How much does a pallet of sod weigh?
Between roughly 1,500 and 3,000 pounds, or 700 to 1,400 kg. The variation is almost entirely water in the soil layer, so a pallet cut after rain is far heavier than the same pallet cut in dry weather. Plan access and handling for the heavy end of the range.
Is it cheaper to sod or to seed a lawn?
Seed is much cheaper per square foot, often by a factor of five to ten, but it takes weeks to establish and needs constant watering and weed control during that time. Sod costs more up front and gives an instant, usable, erosion-resistant lawn the same day.
How long does it take for sod to root?
Shallow rooting usually starts within 10 to 14 days in good conditions, and the lawn is normally knitted well enough for light use in three to four weeks. Full establishment takes a full growing season. Keep it consistently moist for the first two weeks.
What units does this calculator use?
Lawn dimensions are entered in feet and coverage figures in square feet. Results are shown in square feet, square yards and square metres at once, so you can order from a supplier working in any of the three.
