Multi‑Room Tile, Stone & Screed Calculator — What It Is and How to Use It
Plan flooring materials with confidence across multiple rooms or zones. This guide explains what the calculator does, why it matters, and the exact steps to use it correctly.
What this calculator does
The calculator estimates, for each area you add and for the whole project:
Tiles & Boxes
- Tile count based on room size and tile size
- Automatic wastage by laying pattern (Straight, Diagonal, Offset)
- Boxes required using your tiles‑per‑box
Materials
- Grout requirement (kg/m² × area)
- Adhesive requirement (kg/m² × area)
- Screed volume from thickness (mm)
Why it helps: avoids under‑ordering (delays) and over‑ordering (waste), speeds up procurement, and produces a clean report you can print or export.
How to use the calculator (step‑by‑step)
- Add your first area. Each “Area” is one room or zone. Give it a clear label (e.g., Living Room or Bedroom‑1).
- Enter room dimensions. Fill Length and Width in metres. Enter Tile Length and Tile Width in millimetres.
- Pick the laying pattern. Choose Straight, Diagonal, or Offset. The wastage field updates automatically—adjust if your site conditions demand it.
- Set package & consumption values. Enter Tiles per Box, Grout (kg/m²), Adhesive (kg/m²), and Screed Thickness (mm).
- Add more areas if needed. Use + Add Area for every room or zone with different dimensions or tile specs.
- Click

Inputs you provide
- Length, Width (m): room dimensions.
- Tile Length, Tile Width (mm): nominal tile size (e.g., 600×600).
- Pattern & Wastage %: method of laying and expected off‑cuts.
- Tiles per Box: from supplier packaging.
- Grout (kg/m²) & Adhesive (kg/m²): product datasheet values.
- Screed Thickness (mm): average thickness planned.
What the calculator outputs
- Tiles & Boxes per area and project totals
- Grout and adhesive quantities (kg)
- Screed volume (m³)
- Printable Multi‑Room Tile Report with all areas listed
Pro tips for accurate results
- Confirm actual tile size; nominal sizes can vary by a few millimetres.
- Increase wastage slightly for diagonal layouts, tight corridors, or many cutouts.
- Use measured on‑site dimensions (clear of skirtings) for best accuracy.
- For mixed tile sizes or materials, create separate areas rather than averaging.
- Verify screed thickness with levels—thicker spots can add significant volume.
Standards alignment
This tool is aligned with IS 1200 Part 11 (measurement for flooring/wall tiling), IS 15477 (adhesives for ceramic tiles), and IS 2571 (in‑situ cement concrete flooring). These references guide typical wastage ranges, measurement norms, and consumption baselines used in the calculator’s methodology.
FAQs
Can I override the wastage percentage?
Yes. The calculator suggests a value based on pattern, but you can edit the field to suit your site conditions or supplier advice.
Does it save my work?
Yes. Your entries are saved in your browser automatically. You can also export/import JSON to move data between devices.
How do I share results with my team?
Use CSV for spreadsheets, JSON for re‑loading into the calculator, Copy for a quick text summary, or Print for a clean PDF.
