How this is worked out
Lawn area is length × width. Because a standard roll covers 1 m², the area plus any waste allowance rounds up to the number of rolls.
Worked example
- Lawn 8 m × 5 m
- No waste allowance
8 × 5 = 40 m², so 40 rolls
40 rolls
Assumptions and limits
- Assumes rolls covering 1 m² each, which is the common size but worth confirming with the supplier.
- Curved or irregular lawns waste turf on cuts, so a 5 per cent allowance is usual.
