Результаты:
floor + skirting, incl. wastage —
How to order: the total is the stone you need (floor + skirting + wastage), priced by area. The tile/slab count covers that whole total. Skirting is taken as cut from the same stone; rooms are rarely perfectly square, so confirm on site.

What this calculator does
This tile and skirting calculator estimates everything you need to plan a stone or tile floor in one place: the floor area, the number of tiles or slabs to order, and the skirting length and area around the room. Results are shown in both square feet and square metres, with your wastage allowance included, so you can budget and order before you enquire.
How to use it
- Room size. Enter the length and width of the room, in feet/inches or metres/centimetres.
- Tile or slab size. Enter the size of one piece — it's usually printed on the box.
- Wastage. Add a little spare for cuts and breakage; 5–10% is normal.
- Skirting. Enter the skirting height, and the total width of any doorways to skip. Press Calculate.
How it works — the formulas
No hidden maths. These are the exact calculations the tool runs:
Why you may order more than your floor area
Two honest reasons the material to order is higher than the bare floor area. First, the wastage allowance — every job needs spare for cuts, breakage and future repairs. Second, tiles and slabs are sold as whole pieces and can't be split, so the last piece almost always covers more than you strictly need; that surplus isn't waste so much as spare you should keep for repairs.
With large slabs this gap can look big — a single 30 sq ft slab is hard to fit a small remainder into. For large pieces, treat the area figure (sq ft) as what you're paying for, and the piece count as a guide to how many whole pieces that comes to.
Who it's for
Architects and designers specifying a floor, contractors and fabricators pricing a job, importers planning a container, and homeowners working out a budget before they enquire. Anyone who needs a quick, honest material estimate without doing the maths by hand.
Frequently asked questions
How many tiles do I need for a 10 × 10 ft room?
It depends on the tile size. A 10 × 10 ft room is 100 sq ft, so with 1 × 1 ft tiles you'd need about 100 tiles before wastage. The calculator works this out for your exact tile size, rounds up to whole pieces, and adds your wastage allowance.
How much extra should I order for wastage?
5–10% is normal. Use the lower end for simple straight layouts and the higher end for diagonal or patterned layouts, which produce more offcuts. The calculator adds your chosen percentage and then rounds up to whole tiles or slabs.
Why is the material to order more than my floor area?
Because of wastage, the skirting material, and the fact that tiles and slabs come as whole pieces that can't be split — so the final piece covers a little more than the exact area. The surplus is worth keeping for future repairs.
How is skirting measured?
Skirting runs around the room's perimeter, so its length is twice the length plus twice the width, minus the width of any doorways it skips. Its area is that length multiplied by the skirting height. The calculator does this from your room size.
Can I use it for an irregularly shaped room?
Yes. Split the space into simple rectangles, run the calculator for each, and add the results together for your total.
Is skirting always the same material as the floor?
Often, but not always. Skirting is frequently cut from the same stone so the floor line reads as one material, but you can choose a different marble, colour or finish if you prefer. This calculator assumes the same material when totalling.
