Estimate room area and the number of flooring packs to buy.
Formula and convention
Packs = ceiling(length x width x (1 + allowance / 100) / coverage per pack).A worked example
A 5 by 4 m room, 10% allowance, and 2.2 m² per pack requires ten packs.
Scope and precision
Treats the room as rectangular. Subdivide irregular rooms and check manufacturer guidance for diagonal layouts, transitions, and underlay.
