How to measure a room for flooring
A useful flooring estimate begins with the room’s real footprint, not the size printed on a plan or a quick length taken along one wall.
Measure the usable floor in sections
For a rectangle, measure length and width at the finished-floor line and multiply them. For an L-shaped space, split the room into two rectangles, calculate each area, then add them. Measure alcoves, wardrobes, and bays separately; decide whether each will be covered by the same material before adding it.
Room area
area = length × widthExample: a 4.2 m × 3.6 m room is 15.12 m². A 1.2 m × 0.8 m alcove adds 0.96 m², making 16.08 m² before any allowance.
Check the dimensions twice
Measure long walls in more than one place. An old room may be out of square, and a slight difference can turn into an extra pack once cuts and rounding are included. Record units beside every figure so millimetres are not accidentally treated as metres.
Turn area into packs
Use the coverage printed on the chosen flooring pack. Divide the allowance-adjusted area by that coverage and round up to whole packs. Check whether a transition, staircase, or separate room should be included as its own estimate.
