Sod Calculator

Sodding a lawn? Plug in your shape, dimensions, and choice of rolls, slabs, or pallets — we'll tell you exactly how many to order, add a built-in waste factor for cuts and trim, and estimate your total cost when you punch in the price per unit.

Sod Sizing & Coverage

Rolls (also called "big rolls" or "carpet rolls") typically cover 10 sq ft (2 ft × 5 ft) and are popular for large residential jobs because they go down fast and there are fewer seams. Slabs are the small individual pieces — 16″ × 24″, about 2.67 sq ft each — easier to handle solo but more seams to settle. Pallets contain enough slabs (or rolls) to cover roughly 450 sq ft, the typical bulk-buying unit for landscapers.

Tips for an Even Lawn

• Prep the soil: remove debris, till 4–6 inches deep, level, and lightly water before laying.
• Stagger your seams: like a brick pattern. Avoid long continuous joints — they show every time the grass dries out.
• Roll after laying: a water-filled lawn roller pushes sod into firm contact with the soil and helps roots take.
• Water deeply for the first 2 weeks: twice a day until roots set, then taper to normal.

How This Calculator Works

The calculator turns your lawn area into the exact unit sod is sold in. It measures area first — length × width for a rectangle, π × radius² for a circle (entered as diameter), or ½ × base × height for a triangle. Then it adds your waste factor for cuts around beds, walks, and curves, because sod is perishable and you cannot run back for one more piece a day later.

That padded square footage is divided by the coverage of your chosen unit and rounded up: individual rolls cover about 10 sq ft each, hand slabs about 2.667 sq ft (a 16×24-inch piece), and a full pallet covers about 450 sq ft. Cost is units times your price per unit. Sizing in the real selling unit avoids the classic mistake of ordering “500 square feet” and getting a pallet that only covers 450.

A Worked Example

A 50 ft by 40 ft backyard, ordered by the pallet, with 8% waste. Area: 50 × 40 = 2,000 sq ft. Add 8% waste = 2,160 sq ft. Divide by 450 sq ft per pallet = 4.8, rounded up to 5 pallets. At a 2026 price near $185 per pallet of common Bermuda or fescue, that is $925 plus delivery. Install it the same day it is cut, water within the first half hour, and stagger the seams like brickwork.

Estimator's tip: Order sod to arrive the morning you can lay it, not the day before — on a hot pallet it starts yellowing within a day and the inside rolls cook. Prep and grade the soil completely first so the truck unloads onto a ready site. Stagger the seams like brickwork, butt the edges tight without overlapping, and roll and water within the first half hour to knit the roots down before they dry.

What Affects Your Sod Order

• Waste factor — curved beds, trees, and walkways push cut-and-toss waste up toward 10%.
• The selling unit you choose: rolls, slabs, or pallets each have different coverage.
• Grass variety, since pallet square footage can differ slightly by farm and cut size.
• Site shape and obstacles you have to trim around.
• Slope, where you may overlap or pin pieces and use a bit more.
• Delivery timing — sod is perishable, so order to install within a day, not to stockpile.

Frequently Asked Questions

How much sod do I need?

Measure your area in square feet, add 5 to 10% for cuts and waste, then divide by your unit's coverage: about 10 square feet per roll, 2.67 per slab, or 450 per pallet. Round up to whole units.

How many square feet does a pallet of sod cover?

A standard pallet covers about 450 square feet, though it can range from 400 to 500 depending on the farm and grass type. The calculator uses 450 and rounds your order up to whole pallets.

How soon should sod be installed?

Lay sod within 24 hours of delivery, ideally the same day it is harvested. It is a living product that heats and dries on the pallet, so order it to install immediately and water it right after laying.

Should I order sod in rolls or pallets?

Rolls and slabs suit small patch jobs and tight access; pallets are far more economical for full lawns. The calculator prices whichever unit you pick so you can compare coverage and cost.
