Sod Calculator
Home & DIYFreeNo sign-up
Sod is sold by area. Measure the lawn, add 5% to 10% for cutting around edges, then divide by the size of a roll or a pallet. A 20 ft × 10 ft lawn plus 5% needs 210 sq ft: 21 rolls of 10 sq ft, or about half a pallet.
For a triangle: base and height.
Often 400 to 500. Ask your supplier.
| Sod | |
| Lawn area | 200 sq ft |
| With 5% extra | 210 sq ft |
| Square yards | 23.33 sq yd |
| Pieces (10 sq ft each) | 21 |
| Pallets | 0.47 (order 1 or buy pieces) |
Show steps
- Area = 20 × 10 = 200 sq ft.
- Add 5% for cutting: 200 × 1.05 = 210 sq ft.
- Pieces = 210 ÷ 10 = 21, rounded up to 21.
- Pallets = 210 ÷ 450 = 0.47.
How to use the sod calculator
- Choose a shape and enter the lawn size in feet. Split an odd-shaped yard into rectangles, circles and triangles, work out each, and add them; or type the total area.
- Choose the piece size and the pallet size your supplier uses.
- Add extra for trimming, then press Calculate.
How much sod do I need?
Sod (sq ft) = lawn area × (1 + extra%). Divide by the piece size to get rolls or slabs and by the pallet size to get pallets.
| Lawn | Area | +5% | 10 sq ft rolls | 450 sq ft pallets |
|---|---|---|---|---|
| 20 × 10 ft | 200 sq ft | 210 | 21 | 0.47 |
| 30 × 20 ft | 600 sq ft | 630 | 63 | 1.40 |
| 50 × 40 ft | 2,000 sq ft | 2,100 | 210 | 4.67 |
Getting the ground ready
Sod roots best into loose, level soil. Remove old grass and weeds, loosen the top few inches, and spread about 4 to 6 inches of good topsoil if the ground is poor. Rake it level, roll it lightly, and keep the surface about an inch below paths and driveways so the sod sits flush.

Frequently asked questions
How many square feet of sod are on a pallet?
Usually 400 to 500 sq ft, but it depends on the farm and grass type. Check with your supplier before ordering.
How big is a roll of sod?
A common roll is 2 ft × 5 ft, which covers 10 sq ft. Slabs of 16 in × 24 in cover about 2.67 sq ft each.
How much extra sod should I buy?
Add about 5% for simple rectangles and 10% or more for curved edges, beds and lots of obstacles.
Do I need topsoil under sod?
Sod grows best on 4 to 6 inches of loose, good-quality soil. On hard or sandy ground, adding topsoil first helps the roots take hold.
