Sod & Turf Calculator

How much sod or turf you need for a new lawn: area of each part of the yard, extra for edges, and the slabs, rolls and pallets to order.

Sod (turf in the UK and Australia) is sold by area: in slabs or rolls by the piece, or by the pallet in the US. Measure each part of the lawn, add a little for curved edges and cuts, and divide by the size of a piece. A 40 × 25 ft lawn is 1,000 ft²; with 5% extra that's 1,050 ft², which is 394 slabs of 16 × 24 in or 105 rolls of 2 × 5 ft, and 3 pallets at 450 ft² each. In the UK and Australia turf is usually sold by the square metre: a 10 × 8 m lawn needs 84 m² with 5% extra. Enter your lawn areas, rectangles, circles or triangles, and the calculator gives the area, pieces and pallets to order.

How it was worked out
  1. Lawn: 40 ft × 25 ft = 1,000 ft²
  2. Plus 5% for edges and curves = 1,050 ft²
  3. 1,050 ft² ÷ 2.67 ft² per piece = 393.8, rounded up to 394 pieces
  4. 1,050 ft² ÷ 450 ft² per pallet = 3 pallets

Piece and pallet sizes vary by farm and grass type, so check with your supplier. Lay turf within a day of delivery, and prepare the ground first; the topsoil calculator works out what to spread underneath.

Common use cases

  • Order sod or turf for a new lawn
  • Patch or extend an existing lawn

How to use

  1. Choose your units.
  2. Enter each part of the lawn; use circles and triangles for curved and angled areas.
  3. Choose the piece size and keep or change the extra for edges.
  4. Enter what a pallet covers and a price if you have them, then read the results.

FAQ

How much sod is on a pallet?

Typically somewhere around 400 to 500 ft², but it varies by farm and grass type. Ask your supplier and enter their figure; the calculator starts at 450 ft².

How much extra sod should I order?

About 5% for simple shapes and up to 10% for lawns with lots of curves, beds and paths to cut around.

How do I prepare the ground for turf?

Clear weeds and old grass, loosen the soil and level it, and add topsoil if it's poor; 4 to 6 inches (100 to 150 mm) is common for a new lawn. Lay the turf within a day of delivery and water it well. The topsoil calculator works out the soil.
