PRACTICAL GUIDE

How to measure a room for flooring

A rough measurement is enough to get a ballpark and start a conversation. Here's how to take one that's actually useful — and what a survey adds that a tape measure never will.

Flooring being measured and marked out in a room

The basic measurement

Length times width, in metres, at the widest points of the room. Break irregular rooms into rectangles, measure each and add them together. Round up rather than down — under-ordering mid-fit is far more disruptive than a small surplus.

Add a waste allowance

Cuts, scribes and setting-out mean the floor area is never the order quantity. Straight plank in a simple rectangular room needs the least; diagonal lays, herringbone and chevron need considerably more because of the angled offcuts. We calculate the exact allowance for your specific lay pattern when we quote.

  • Measure at the widest points, including bays and alcoves
  • Include the threshold area of each doorway
  • Note anything fixed: hearths, boxings, kitchen island bases
  • Photograph each doorway and any level change

What your tape can't tell us

Subfloor moisture content, flatness across the room, whether the deck moves, and how much clearance there is under the doors once the new build-up is in. Those four things drive the preparation cost, and they're the reason we survey before issuing a price.

Sending it to us

Room-by-room dimensions plus photos of each doorway is genuinely useful when you enquire — it lets us give you a sensible indication and book the right length of survey slot.

Frequently asked

Should I measure under the kitchen units?
Measure both ways and tell us. Whether the floor runs under the units or up to them is a decision worth making deliberately.
Do stairs get measured differently?
Yes — stairs are counted per tread and riser, not by area. Tell us the number of steps.
How accurate does it need to be?
For an indication, roughly. For an order, we measure on site — that's on us, not you.
Can you quote from a floor plan?
We can give an indication, but the plan says nothing about moisture or flatness, so the survey still happens before the price is fixed.

In short

Widest points, broken into rectangles, rounded up, with doorways and fixed obstructions noted. Good enough for an indication — the survey handles moisture, flatness and clearances before anything is ordered.
