Landscaping & lawn
Sod Calculator
Calculate how much sod you need for a lawn or landscaping project. Estimate project area, extra allowance, sod rolls or pieces, pallets, purchased coverage, and optional material cost.
Sod calculation guide
How to calculate how much sod you need
Start with the total square footage of the lawn or landscaping area, subtract patios, planting beds, walkways, structures, or other areas that will not receive sod, then add any extra allowance you want for cuts, shaping, measurement differences, or other project-specific needs. HomeMeasureWorks can convert the resulting net sod area into individual rolls or pieces and, when supplier pallet information is entered, complete pallets.
Sod calculator formula
For a rectangular lawn, calculate the project area first:
If part of the measured area will not receive sod, subtract that excluded area first:
If you add an extra allowance:
Then divide the required area by the coverage of one sod roll or piece:
Because partial rolls or pieces may not be available, the calculator rounds the purchase quantity upward to the next whole unit.
Sod calculation example
Suppose a lawn measures 30 feet by 20 feet, 100 square feet of the measured area will not receive sod, you add a 5% allowance, and each sod roll or piece covers 10 square feet.
In this example, the project needs53 individual rolls or pieces. Buying those units provides 530 ft² of sod, leaving 5 ft² beyond the required 525 ft² because the purchase quantity is rounded upward.
How many rolls or pieces of sod do I need?
Enter the square-foot coverage provided by your sod supplier for one roll or piece. The calculator divides the required lawn area by that coverage and rounds upward when necessary.
How many pallets of sod do I need?
If your supplier sells complete pallets, enter the number of rolls or pieces on one pallet. The calculator first determines how many individual units are required, then rounds the pallet quantity upward.
For example, if you need 63 pieces and one pallet contains 50 pieces:
Those two pallets would contain 100 pieces. If each piece covers 10 ft², the pallet purchase would provide 1,000 ft² of sod even though the project requires only 630 ft².
Individual sod vs. full pallets
Individual rolls or pieces
The calculator rounds only to the next whole sod unit. This can produce less excess material when a supplier allows individual units to be purchased.
Full pallets
Pallet quantities are rounded to complete pallets. This can create substantially more purchased coverage than buying exactly the required number of individual units.
HomeMeasureWorks shows these purchase methods separately rather than assuming that a pallet can always be split.
How does the sod allowance work?
The optional allowance increases the measured lawn area before the calculator determines the number of sod units required.
There is no single allowance percentage that is correct for every sod installation. The appropriate amount can depend on lawn shape, cuts, measurement accuracy, layout, damaged pieces, supplier rules, and other project conditions.
How much coverage is on a sod pallet?
Pallet coverage depends on both the number of sod units on the pallet and the coverage of each unit.
Because sod suppliers may use different roll, slab, piece, or pallet formats, this calculator deliberately does not assume one standard pallet coverage.
Enter the supplier's actual unit coverage and units per pallet for the most relevant estimate.
How to estimate sod cost
Cost by roll or piece
The individual-unit estimate uses the rounded-up number of rolls or pieces.
Cost by pallet
The pallet estimate uses the rounded-up number of complete pallets.
The two costs are shown separately so you can compare the quantities entered for your supplier. Delivery, installation, soil preparation, taxes, deposits, minimum orders, equipment, and other charges are not automatically included.
How to measure an irregular lawn for sod
If your lawn is not a simple rectangle, break it into smaller measurable shapes, calculate each section, and add the areas together.
Once you know the combined square footage, chooseKnown area in the Sod Calculator.
Tips for a more accurate sod estimate
Recheck the dimensions and include every section that will receive sod.
Patios, buildings, planting beds, walkways, and other excluded areas can reduce the sod quantity required.
Enter the actual coverage of the sod product you plan to purchase.
Use the supplier's actual number of rolls or pieces per pallet rather than assuming a standard pallet size.
Some suppliers sell individual pieces, partial pallets, full pallets, or use minimum purchase quantities.
Sod is a living product, so follow the supplier's handling, storage, and installation guidance after delivery.
Sod calculator FAQ
How do I calculate how much sod I need?
Calculate the lawn area in square feet, apply any desired extra allowance, and divide the resulting area by the coverage of one sod roll or piece. Round upward when a whole-unit purchase is required.
How many square feet of sod do I need?
For a rectangular lawn, multiply length by width to find square footage. For irregular lawns, calculate the areas of smaller sections and combine them.
How many rolls of sod do I need?
Divide the required lawn area by the square-foot coverage of one sod roll or piece. The calculator rounds upward to a whole unit.
How many pallets of sod do I need?
Enter the number of rolls or pieces per pallet. The calculator divides the required whole-unit quantity by that pallet size and rounds upward to a complete pallet.
How many square feet are on a pallet of sod?
There is no universal pallet coverage. It depends on the number of sod units on the pallet and the coverage of each unit. Check the supplier's specifications for the sod you plan to purchase.
Should I add extra sod?
That depends on the project. Extra material may be useful for cuts, shaping, measurement differences, damaged pieces, or other project-specific conditions. The calculator lets you choose the allowance rather than imposing a fixed percentage.
Why does the calculator round sod up?
The calculator rounds individual units upward because a partial roll or piece may not be available. Pallets are also rounded upward when the estimate assumes complete pallets.
Can I subtract patios, walkways, or planting beds?
Yes. Enter the total measured project area, then use Excluded area for patios, planting beds, walkways, structures, or other spaces that will not receive sod. The calculator subtracts those areas before applying the sod allowance and calculating rolls, pieces, or pallets.
Can I enter the lawn's known square footage?
Yes. Select Known area and enter the total lawn area directly instead of entering length and width.
Can I compare sod piece cost with pallet cost?
Yes. Enter a price per roll or piece and a price per pallet. The calculator shows the two purchase estimates separately.
Is sod also called turf?
Terminology varies by region. Sod generally refers to established grass and soil sold for transplanting, while turf may be used more broadly to describe grass-covered ground or similar products.

Assumptions and limitations
This calculator estimates sod quantity from the measurements, allowance, product coverage, pallet information, and prices you enter. It does not determine whether a particular sod type is suitable for your climate, soil, sunlight, irrigation, or installation conditions.
Unit and pallet calculations assume the supplier information you enter is accurate. Pallet estimates assume complete pallets unless your supplier allows another purchasing method. Cost estimates exclude charges that are not included in the prices entered.
