Estimate flooring area, waste allowance and the number of packs required.
Multiply room length by width.
Extra material covers cuts, pattern matching and damaged pieces.
Divide required area by the coverage per pack and round up to a whole pack.
A common planning allowance is around 5–15%, but complex layouts can need more.
Flooring is normally sold in complete packs, so partial packs cannot usually be bought.
Split the room into simple rectangles, calculate each area and add them together.
