Sod Calculator
Sod is sold in rolls, by the square foot, and by the pallet, and the three do not always agree. This converts your measurement into all of them, plus the soil you need underneath.

Figure. Sod is sold in rolls of about 10 sq ft and delivered on pallets. Order for the pallet, not for the roll, once the job is large.

Why sod needs a waste allowance
Rolls are laid edge to edge but not perfectly. Curves, planting beds, and the trimmed ends at every wall all consume material that the plain area figure does not account for. A simple rectangle against straight edges needs about three percent. A lawn with a curved border, a tree island, or several corners needs eight to ten. This calculator defaults to eight, which is the figure that lands closest for a typical suburban yard. Ordering the exact area is the most common way to end up one roll short at four in the afternoon.
Rolls, pallets, and how they are actually sold
Most sod in North America is cut in rolls of about 10 square feet, though some suppliers cut 5 square feet or sell larger slabs. A pallet usually holds 450 to 500 square feet. That means a 1,000 square foot lawn is two and a bit pallets, and the supplier will usually break a pallet rather than sell you three. Ask whether the pallet figure is 450 or 500 before you calculate, because on a large lawn that difference is a whole pallet.
What has to happen before the sod arrives
Sod is a living product with a shelf life measured in hours, not days. It needs to be laid within roughly 24 to 48 hours of harvest, which means the ground has to be ready before you order. Preparation is: clear the old surface, till or turn the top four to six inches, grade away from the house so water runs off, roll or firm the soil so it does not settle unevenly, and apply starter fertiliser raked into the top inch. Soil preparation is where most failed lawns fail, not in the sod itself.
The first two weeks decide the outcome
New sod needs water immediately and then twice a day for the first week, enough that the soil under the rolls is wet, not just the surface. Lift a corner on day three to check; if the soil under the sod is dry, the roots will not knit. After the first week, reduce to once a day, then every other day. Do not mow until the sod resists a gentle tug, and when you do, take off no more than a third of the height.
Rolls, pallets and delivery math
A roll is about 10 sq ft, and a pallet holds 450 to 500 sq ft depending on the grower and grass type. Ordering in pallets is cheaper per square foot but leaves you with leftovers, while ordering rolls means paying per piece.
For anything under 1,000 sq ft, work out both and compare: one pallet with a delivery fee often beats 45 individual rolls you have to collect yourself.
Season and grass type
Cool-season grasses establish best in early autumn, warm-season grasses in late spring. Laying at the wrong end of the season means the roots never get time to establish before the first stress period, whether that is frost or drought.
Grass type also changes the roll weight and the price: bluegrass blends are heavier and thirstier, bermuda is lighter and faster to spread. Confirm what the grower is cutting, because the pallet price is tied to it.
Worked example: 30 x 20 ft lawn
| Lawn area | 30 x 20 = 600 sq ft |
| With 8% overlap waste | 648 sq ft |
| Rolls at 10 sq ft | 65 rolls |
| Pallets at 450 sq ft | 2 pallets |
| Topsoil to level | 2 cu yd |
| Starter fertilizer | 1 bag per 1,000 sq ft |
| Budget band | $227 low, $486 mid, $1,037 high |
Mistakes that cost real money
Buying sod before the ground is ready
Sod is a 24 to 48 hour product. If the soil is not levelled, amended and watered before it arrives, it sits in a stack and heats up. Sod laid on unprepared ground fails no matter how good the sod was.
Skipping the soil prep
Roughly 70% of a sod job is preparation: remove the old lawn, till 4 to 6 in, add organic matter, grade for drainage and firm it. Sod laid on compacted clay roots into a hard pan and dries out within weeks.
Under-ordering to save money
Rolls overlap slightly at the seams and edges get trimmed. Five to ten percent extra is normal. A lawn that runs 40 sq ft short looks like a patch of bare soil for a year, because you cannot buy six rolls without a delivery fee.
Not watering the first week
New sod needs to be soaked the day it goes down and kept damp for 10 to 14 days. One missed day in the first week can kill seams that were laid perfectly, and the damage only shows up a month later.
Laying in the wrong direction
Run rolls lengthwise, stagger the seams like brickwork, and butt them tight without overlapping. Parallel seams that line up across the lawn become visible lines that never fully disappear.
Frequently asked questions
How many square feet are on a pallet of sod?
Typically 450 to 500 square feet, depending on the grower and the roll size. Confirm the number with the supplier before ordering. On a lawn over 2,000 square feet the difference between 450 and 500 is more than a full pallet.
How long can sod sit before it is laid?
24 to 48 hours, and shorter in hot weather. Sod is a living plant with roots that begin to die once it is cut. If it cannot be laid the day it arrives, unroll it in the shade and water it, but do not stack it in a heap overnight.
Do I need topsoil under new sod?
If the existing soil is compacted, clay-heavy, or uneven, yes, about an inch raked in. Sod roots need contact with loose soil to knit. On already-worked loam, tilling and firming is usually enough without importing soil.
How often should I water new sod?
Twice a day for the first week, enough to soak the soil beneath the rolls. Then once a day for a week, then every other day. Watering lightly and often is the common error; the water has to reach the soil, not just wet the grass.
Can sod be laid over existing grass?
No. The old grass has to be removed or killed and the surface prepared. Sod laid over existing turf has no soil contact, the old grass rots underneath, and the new lawn fails within a month. This is not a shortcut that sometimes works.
