Inputs
ℹ️Total lawn area to be sodded or turfed.
Sod Source
ℹ️450 sq ft is a common general reference, but actual pallet coverage varies significantly by grass species and region — confirm with your supplier.

Sod Needed
11 pallets
400 sq ft — common warm-season / southern US
Lawn Area

371.6122 m²
Order Area
Lawn area: 4000 sq ft (371.6122 m²)
Order area (+5% cutting/edge waste): 4200 sq ft
390.1928 m²
Pallets
Pallet size: 400 sq ft
Pallets needed: 11
≈40 standard rolls per pallet (reference figure only).
Assumptions Used
Order area adds a 5% cutting/edge-fitting waste allowance on top of the bare lawn area — this covers scrap from trimming pieces to fit curves, corners, and obstacles, not settling (sod doesn't settle the way loose fill volume does). A heavily irregular or obstacle-dense lawn commonly needs more than this default; consider padding your entered area for those cases. Roll, pallet, and slab sizes are genuinely supplier- and grass-species-dependent (no single fixed industry standard exists for any of the three) — the presets offered are commonly cited reference figures, not guarantees; confirm exact sizes with your supplier before ordering. This calculator estimates material quantity only — it does not verify soil preparation, grading, or irrigation readiness.

St. Augustine sod quantity
St. Augustine grass is a popular warm-season lawn choice in the Gulf Coast and Southeast US, valued for its shade tolerance and thick, carpet-like coverage — it's typically sold on pallets covering somewhat less area than some cool-season species, since its wider blade and denser cut piece can run a bit heavier per pallet.
This page defaults to a 4,000 sq ft lawn with a 400 sq ft pallet, a commonly cited reference figure for warm-season sod — edit the inputs above to match your actual lawn size and your local supplier's confirmed pallet coverage.
Sod / Turf Calculator Formula: How Is It Determined?
Lawn area combines with a waste allowance into an order area, which then converts into a roll, pallet, or slab count.
Step 1 — Lawn Area
By Dimensions: Area = Length x Width
By Total Area: Area = entered value (converted to sq ft if entered in m²)
Either enter a rectangular lawn's length and width, or enter its total area directly — useful for an irregular lawn where length x width doesn't apply.
Step 2 — Order Area
Order Area = Lawn Area x (1 + 5% cutting/edge waste)
The 5% allowance covers scrap from trimming pieces to fit curves, corners, and obstacles — this is a cutting allowance, not a settling allowance, since sod doesn't settle the way loose fill volume does.
Step 3 — Roll / Pallet / Slab Count
Units Needed = ceil(Order Area / Unit Size)
Unit size is stored as a canonical sq ft figure internally, so US roll/pallet sizes (sq ft) and UK/AU slab/turf-roll sizes (m²) come from the same underlying calculation, or enter a custom unit size in either unit.
Worked Example
This example walks through your current inputs above, using the same steps as the Formula section.
Input Values Used
| Input | Value | Why it is used |
|---|---|---|
| Lawn Area | 4000 sq ft (371.6122 m²) | Sets order area |
| Sod Source | Pallets | Sets unit count divisor |
| Pallet Size | 400 sq ft — common warm-season / southern US — 400 sq ft | Sets the pallet-count divisor |
Step 1 & 2 — Area
| Calculation | Result |
|---|---|
| Lawn Area | 4000 sq ft (371.6122 m²) |
| Order Area = Lawn Area x (1 + 5%) | 4200 sq ft (390.1928 m²) |
Step 3 — Pallets
| Calculation | Result |
|---|---|
| Pallets = ceil(4200 / 400 sq ft per pallet) | 11 pallets |
Figures above are rounded for display; the roll/pallet/slab count is always calculated from full, unrounded values, so it can occasionally look off by one unit if you redo the division yourself using the rounded figures shown.
Therefore, a 4000 sq ft lawn needs approximately 11 pallets of sod.
