How the calculation works
Required coverage = net area × (1 + allowance ÷ 100). Divide by coverage per pack and round up to whole packs. For 47 m², 7% and 8.5 m² packs, the result is six packs covering 51 m².
Pack rounding and the allowance are separate. Confirm product, pattern, pack composition and border requirements before ordering. This tool calculates coverage, not construction suitability.
