How it is calculated

The tool adds a 5% allowance for cutting and waste, then divides by the coverage of one roll. Order area = lawn area × 1.05 and rolls = ceil(order area / 0.836), where area is in square metres and 0.836 m² is the coverage assumed for one roll. The roll count is always rounded up to a whole roll, because you cannot buy a fraction. The area must be zero or more. Complex lawns with curves, many corners or slopes may need more than 5%, and roll sizes differ between suppliers, so check the coverage printed on the product.

Worked example

A lawn of 120 m². With 5% extra: 120 × 1.05 = 126.00 m². Rolls = 126 / 0.836 = 150.7, which rounds up to 151 rolls. Because of the rounding up, a few square metres of spare turf remain for repairs.

Common mistakes

  • Entering the area in square feet or square yards instead of square metres.
  • Measuring only the bounding rectangle of a lawn with curved beds and overestimating, or ignoring odd corners and underestimating.
  • Assuming every supplier sells rolls of the same size; the 0.836 m² per roll is an assumption.
  • Adding extra waste on top of the 5% that is already included.

About this calculator

This calculator works out how much sod (turf) you need for a lawn: enter the area to cover, and it converts that into square footage plus the number of rolls or pallets to order, based on standard sod piece sizes.

Homeowners planting a new lawn and landscapers quoting installation jobs use it to avoid under-ordering (which means a delayed delivery) or over-ordering (which means wasted sod that dies before it can be laid). It saves the manual math of converting an odd-shaped yard into standard sod units.
