1. Overview — What the Calculator Covers
This calculator estimates the number of tiles, boxes, adhesive, and grout needed for a rectangular or square room. It accounts for:
- Room dimensions (length and width)
- Tile size (including custom sizes)
- Wastage percentage (cuts, breakage, spares)
- Layout pattern (straight, diagonal, herringbone)
- Grout joint width
2. Inputs You Need
To use the calculator effectively, gather these measurements:
- Room Length & Width (in meters or feet)
- Tile Dimensions (length and width in mm or inches)
- Wastage Percentage (typically 10% for straight lay, 15% for diagonal, 20% for complex patterns)
- Grout Joint Width (usually 2-5mm)
- Tiles per Box (varies by manufacturer and tile size)
3. Core Formulas & Unit Notes
Room Area: Length (m) × Width (m) = Area (m²)
Tile Area: (Tile Length (mm) ÷ 1000) × (Tile Width (mm) ÷ 1000) = Tile Area (m²)
Number of Tiles: (Room Area ÷ Tile Area) × (1 + Wastage%) = Total Tiles
Number of Boxes: Total Tiles ÷ Tiles per Box (round up to whole boxes)
4. Common Tile Sizes & Box Packaging
Here are typical tile sizes and their coverage:
| Tile Size (mm) | Tiles per m² | Typical Tiles per Box | Coverage per Box (m²) |
|---|---|---|---|
| 300 × 300 | 11.11 | 10–12 | 0.9–1.08 |
| 600 × 600 | 2.78 | 4–6 | 1.44–2.16 |
| 800 × 800 | 1.56 | 3–4 | 1.92–2.56 |
5. Layout Patterns and Their Waste Factors
Different layouts generate different amounts of waste:
- Straight Lay: 5–10% wastage
- Diagonal: 10–15% wastage
- Herringbone/Complex: 15–20% wastage
6. Step-by-Step Calculation (with Example)
Example: A room measuring 4m × 5m using 600×600mm tiles with 10% wastage.
- Room Area = 4m × 5m = 20 m²
- Tile Area = (600/1000) × (600/1000) = 0.6 × 0.6 = 0.36 m²
- Base Tiles = 20 ÷ 0.36 = 55.56 → round to 56 tiles
- With 10% wastage = 56 × 1.10 = 61.6 → round to 62 tiles
- If 4 tiles per box: 62 ÷ 4 = 15.5 → round to 16 boxes
7. Grout & Adhesive Quantities
Adhesive: Typically 4–6 kg per m² depending on tile size and bed thickness.
Grout: For 2mm joints, approx. 0.5–1 kg per 10 m².
8. Tips to Reduce Waste & Simplify Installation
- Plan the layout to minimize cuts at visible areas
- Use larger tiles for fewer grout lines and less cutting
- Buy all tiles from the same batch to avoid color variations
- Keep extra tiles (5–10%) for future repairs
9. Frequently Asked Questions (FAQ)
How many 600x600 tiles in 1 square meter?
Approximately 2.78 tiles per m² (1 ÷ (0.6 × 0.6) = 2.777...).
How much extra tile should I buy for wastage?
For straight lay: 10%, diagonal: 15%, complex patterns: 20%.
Can I use this calculator for bathroom walls?
Yes, but remember to subtract areas for windows, doors, and fixtures.
What if my room isn't a perfect rectangle?
Break the room into rectangular sections, calculate each, then sum.
