Plan finishes with accurate marble quantity estimates. Compare tile and slab options across any room. Include waste, boxes, weight, and budget in minutes today.
| Room | Length | Width | Cutouts | Tile Size | Waste | Estimated Pieces |
|---|---|---|---|---|---|---|
| Lobby | 10.00 m | 6.00 m | 2.00 sqm | 600×600 mm | 8% | ~ 182 |
| Corridor | 18.00 m | 2.00 m | 0.50 sqm | 600×600 mm | 10% | ~ 111 |
| Washroom | 4.00 m | 3.00 m | 0.80 sqm | 300×300 mm | 12% | ~ 133 |
This calculator converts site measurements into purchase-ready quantities. Start with net floor area, subtracting voids such as lifts, stairs, or service shafts. For repeated rooms, multiply by the count. A 5.0 m × 4.0 m room equals 20.0 sqm before cutouts. The results also show square feet for supplier comparison and reporting.
Waste allowance protects you from breakage, trimming, and future repairs. Straight patterns often work with 5–8% waste, while diagonal layouts, borders, and heavy corner cutting can require 10–15%. When your design includes book-matching or strict veining alignment, keep extra stock. The calculator applies waste to total area first, then rounds pieces upward to avoid shortages.
Coverage is calculated from the selected piece size. A 600×600 mm tile covers 0.36 sqm, so 21.6 sqm with waste typically needs ceil(21.6 ÷ 0.36) = 60 pieces. Slabs can be entered the same way using their length and width. Packaging is handled separately: if a box holds 4 pieces, the tool rounds boxes up for safe ordering.
Weight estimation uses volume and density, helping with handling plans and vehicle capacity. Volume equals area-with-waste multiplied by thickness (in meters). For 18 mm marble over 21.6 sqm, volume is 0.3888 m³. With 2700 kg/m³ density, the estimated mass is about 1,050 kg. Always validate with supplier datasheets for your specific stone type.
You can price by area or by piece, depending on local practice. Area pricing supports quick budget checks, while per-piece pricing fits bespoke slabs or special finishes. Use the downloads to share procurement summaries with your team. For best results, confirm unit consistency (sqm vs sqft), include edging or skirting as separate line items, and update waste after final layout approval.
Use the system that matches your drawings and supplier quotes. The calculator converts and displays both sqm and sqft, but pricing follows the unit system you selected to keep totals consistent.
Marble is ordered in whole pieces and whole boxes. Rounding up ensures coverage after cutting losses and avoids delays caused by short orders, especially when a stone batch is later unavailable.
Enter the installed thickness of the marble piece. It affects volume and weight, not surface coverage. Common interior tiles are 12–20 mm, while heavy-duty applications may use thicker sections.
Measure those surfaces separately and run additional calculations, then combine totals in procurement. Different piece sizes or thicknesses often apply, so separating them improves accuracy and reduces waste.
No. 2700 kg/m³ is a practical default for many marbles, but stone composition varies. If your supplier provides a tested density, enter it to improve transport and lifting estimates.
Yes, but calculate each tile size as a separate run because coverage differs. Then sum the costs and weights. Mixed layouts usually need higher waste due to more cutting and alignment work.
