The short answer
Measure each room's floor area, add an allowance for cutting wastage and breakage, and round up to whole slabs or tiles. Simple rectangular rooms need the least extra; many small rooms, curves, borders and matched veining need more. Order everything for one area from one lot, because topping up later rarely matches.
Key takeaways
- Measure each room, add a wastage allowance, and round up to whole slabs.
- Complex layouts and matched veining need more allowance than plain rectangular rooms.
- Order everything for one area from one lot, plus spare pieces for repairs.
Advice for you
Tell us who you are and we will show you what matters most in this guide.
I am building or renovating my home
Use the calculator for a first figure, then send us your floor plan. Ordering a little more now is far easier than trying to match a new lot later.
Book a visit to see full slabsI am an architect or interior designer
Where veins must flow or open like a book, mark the slab sequence on the layout. We confirm quantities from the drawing and tell you whether the lot has enough consecutive slabs.
Request samples for a clientI am a contractor or builder
Send room-by-room areas, steps, skirting and thresholds separately. A written quantity confirmed from the drawing avoids short supply mid-job.
Work out quantitiesI live outside Bengaluru
Running short is costlier when the store is far away. Have us confirm the quantity from your plan before dispatch, and keep a few spare pieces from the same lot.
Choose slabs on a video callHow do you work out the quantity, step by step?
- Measure each room: length times width. Add areas of steps, skirting and thresholds separately.
- Add a wastage allowance: less for large rectangular rooms, more for complex layouts and matched veining.
- Convert to slabs or tiles, rounding up.
- Order all of it from one lot, plus a few spare pieces for future repairs.
| Layout | Wastage |
|---|---|
| Large rectangular rooms | Lowest |
| Many small rooms and passages | Higher |
| Diagonal laying, borders and inlays | Higher |
| Book-matched or continuous veining | Highest |
The stone quantity calculator gives a first estimate. We confirm the quantity from your floor plan before you order. Bold-veined stones such as Calacatta and Arabescato need more allowance when you want veins to flow; plain stones such as Kota Blue, Tandur Yellow and Absolute Black need less.
