Ordering stone is simpler than it looks: measure your area, add a wastage allowance, and order in square metres. Here is exactly how — and the mistakes to avoid.
1. Measure the area
Length × width in metres for each rectangular section, then add the sections together. For L-shaped rooms, split the room into rectangles. Measure into door thresholds and under kitchen units if the floor goes down first (it usually should).
2. Add wastage — don't skip this
Every job loses tiles to cuts at walls, doorways and pipework, plus the odd breakage. Allow 10% for a straight lay in a simple room, 15% for patterns (herringbone, offset), diagonal lays or rooms with lots of cuts. Running short is expensive: a later top-up order may come from a different batch with slightly different tone.
3. Let the calculator do it
Every stone product page on our site has a built-in calculator: enter your area, pick your wastage, and it converts to the exact order quantity — and tells you how many tiles that is for your chosen size. Try it on our Jaipur or Dijon ranges.
Batch matters
Natural stone varies between production batches. Ordering your full quantity in one go (including wastage) means every tile comes from the same batch — another reason to get the sums right first time. Note most of our stone has a minimum order, shown on each product page.
