Sod Calculator
Estimate how much sod you need for a new lawn, in square feet, pallets, or rolls, based on the area's length and width.
How this is calculated
Area is calculated from the shape you select — rectangle (length × width), circle (π × radius²), triangle (½ × base × height), circular ring (π × (outer radius² − inner radius²)) for a lawn ring around a driveway loop or bed, or trapezoid (average of the two parallel sides × width). We add your selected waste percentage to cover irregular edges, curves, and cutting around obstacles like trees and beds. Pallet coverage assumes approximately 450 square feet per pallet and large-roll coverage assumes approximately 10 square feet per roll, though exact coverage varies by sod farm and grass variety.
The material weights, waste allowances, and rounding rules behind every calculator are documented on our methodology page.
Example calculation
Sod needed for common lawn sizes
Most suburban front and back lawns fall between a few hundred and several thousand square feet. The table uses the calculator's assumptions: 5% waste, about 450 ft² per pallet, and about 10 ft² per large roll. Always confirm coverage with your sod farm, since pallets and rolls differ by grower.
| Lawn area | Square yards (with 5% waste) | Pallets | Large rolls |
|---|---|---|---|
| 500 ft² | 58 yd² | 2 | 53 |
| 1,000 ft² | 117 yd² | 3 | 105 |
| 2,500 ft² | 292 yd² | 6 | 263 |
| 5,000 ft² | 583 yd² | 12 | 525 |
| 10,000 ft² | 1,167 yd² | 24 | 1050 |
Pallets are always rounded up to a whole pallet, so you usually end up with some extra to use on edges and patches.
Choosing a grass type
The right grass depends on your climate zone, how much sun the lawn gets, and how much traffic and maintenance you want. Ask your sod supplier which varieties are grown locally. Locally grown sod is fresher and usually already suited to your conditions.
| Grass | Type | Best for | Watch out for |
|---|---|---|---|
| Kentucky bluegrass | Cool-season | Full sun, dense lawns, cold winters | Needs regular water in summer heat |
| Tall fescue | Cool-season | Mixed sun and light shade, drought tolerance | Clumps instead of spreading |
| Perennial ryegrass | Cool-season | Fast establishment, often blended | Less tolerant of extreme cold or heat |
| Bermuda | Warm-season | Full sun, heavy foot traffic, heat | Goes dormant and brown in winter; poor in shade |
| Zoysia | Warm-season | Dense turf, moderate shade | Slow to establish |
| St. Augustine | Warm-season | Shade tolerance, coastal areas | Needs frequent water and doesn't tolerate heavy traffic |
| Centipede | Warm-season | Low-maintenance lawns on acidic soil | Doesn't recover well from heavy wear |
Cool-season grasses grow best in the north and warm-season grasses in the south. A band of states in between, often called the transition zone, can grow either.
When to lay sod
- Cool-season grasses root best in early fall, when soil is warm and air is cool. Spring is the second-best window. Avoid midsummer heat.
- Warm-season grasses do best when laid in late spring through early summer, once soil temperatures stay warm. Laying them in late fall risks poor rooting before dormancy.
- Avoid frozen ground and drought periods, and don't lay sod if you can't water it consistently for the first two weeks.
- Schedule delivery for the morning you plan to lay it. Sod stacked on a pallet generates heat and can start to yellow within a day or two.
Preparing the soil and laying the sod
Good soil preparation does more than anything else to determine how fast sod roots. Kill or strip existing grass and weeds, then loosen the top 4 to 6 in of soil. Remove rocks and debris, and grade so the finished soil sits about 1 in below sidewalks and driveways. Sod is about an inch thick, and this keeps it flush with hard surfaces.
Spread a thin layer of starter fertilizer and rake smooth. Lightly moisten the soil right before you lay the sod, but don't leave it muddy.
Start along the longest straight edge, such as a driveway or walkway. Stagger the seams like bricks, push the edges tightly together without overlapping, and use a sharp knife to trim around beds and trees. Avoid stretching the pieces, and don't leave small slivers at the edges, since those dry out first. Roll the lawn lightly when you finish to press the roots against the soil.
Watering and first mowing
| Time after installing | What to do |
|---|---|
| Right away | Water thoroughly, until the soil underneath is wet to about 4 in |
| Days 1–14 | Keep the sod and soil moist, usually by watering once or twice daily, more in hot or windy weather |
| Weeks 2–3 | Reduce frequency but water more deeply. Gently tug a corner: if it resists, roots are taking hold |
| Around week 2–3 | Mow for the first time once the grass is tall enough, and never remove more than one-third of the blade height |
| After 4–6 weeks | Switch to a normal deep, infrequent watering schedule and apply regular fertilizer |
Keep foot traffic off for the first 2–3 weeks, and keep pets and mowers away until roots are anchored.
Sod versus seed
| Sod | Seed | |
|---|---|---|
| Upfront cost | Higher, often several times more per square foot | Low |
| Time to usable lawn | Weeks | Months, with careful watering |
| Weeds and erosion on slopes | Instantly covered | Bare soil is vulnerable until it fills in |
| Choice of grass types | Limited to what farms grow | Wide variety |
| Best timing | More flexible, apart from extreme heat or frost | Narrow windows in spring or fall |
Seed is a reasonable choice for large areas on a budget. Sod is worth the extra cost on slopes and high-visibility lawns.
