Frequently asked questions
What formula does this calculator use?
Area covered = length × width; Turf needed = ceil(length × width × coats ÷ cov × (1+waste ÷ 100)). Variables: length = length in m, width = width in m, coats = coats or layers, waste = waste allowance in %. Fixed values: cov = 1.
What do I need to enter?
You need length (m), width (m), coats or layers, waste allowance (%). Results update as you type.
What is an example result?
With the default inputs (length = 5 m, width = 4 m, coats or layers = 1, waste allowance = %5), the results are: area covered 20.00 m²; turf needed 21 m² rolls.
What coverage does this assume?
It assumes one m² rolls covers 1 m² per coat. Always check the coverage printed on your product, because it varies by brand and surface.
