Sod Calculator

Sod is priced by area, so measure carefully. Enter your lawn size and allowance for cuts to see exactly how many slabs or rolls and pallets to order.

Calculate sod

Units
5% for simple shapes, 10% or more for curves and many beds.
Varies by supplier, commonly 400 to 500 sq ft (40 to 60 m²).
View formula
Sod to order = area × (1 + waste %) Pieces = sod area ÷ piece size (round up) Pallets = sod area ÷ pallet coverage

How to use the Sod Calculator

  1. Measure the lawn, split irregular areas into rectangles and add them up.
  2. Add 5 to 10% waste for edges, curves and cutting around beds.
  3. Choose your supplier’s piece size and pallet coverage.
  4. Press Calculate.

Sod formula

Sod = area × (1 + waste %) Pieces = sod ÷ piece area · Pallets = sod ÷ pallet coverage

Worked example

A 40 × 25 ft lawn (1,000 sq ft) with 5% waste, 16 × 24 in slabs and 450 sq ft pallets:

  1. Sod: 1,000 × 1.05 = 1,050 sq ft
  2. Slabs: 1,050 ÷ 2.67 = 394 pieces
  3. Pallets: 1,050 ÷ 450 = 2.33 → 3 pallets (or 2 pallets plus extra pieces if your supplier sells part-pallets)

Measuring irregular lawns

Break the lawn into rectangles, triangles (½ × base × height) and circles (π × r²), work out each area and add them up. Subtract beds, patios and paths that won’t be sodded, then use “Total area” mode.

Laying sod successfully

  • Prepare the soil first: remove old turf, loosen the top 4 to 6 in, level it and lightly firm it.
  • Lay sod the day it arrives, staggering joints like brickwork and butting edges tightly.
  • Water immediately and keep it moist for the first two weeks while roots knit into the soil.

FAQ

Sod Calculator: frequently asked questions

How many square feet are in a pallet of sod?

Commonly 400 to 500 sq ft, but it varies by grower and grass type. Always confirm with your supplier.

How big is a piece of sod?

Standard slabs are often 16 × 24 in (2.67 sq ft); rolls are often 2 × 5 ft (10 sq ft). In metric markets, 1 m² rolls are common.

How much extra sod should I order?

About 5% for simple rectangles and 10% or more for curved edges, slopes and lots of obstacles.

Is sod or seed cheaper?

Seed is far cheaper per square foot but takes weeks to establish; sod gives an instant lawn at a higher cost. Use the grass seed calculator to compare quantities.
