Enter your area and tile size to work out exactly how many tiles — and boxes — you need, with the grout joint and a wastage allowance factored in.
Pick a standard size or enter your own. The nominal tile dimensions in millimetres.
▼Spacing between tiles.
Cuts & breakage.
Check the pack — it varies by tile size. Used to work out how many boxes to buy.
Tile counts include the grout joint in each tile's footprint plus your wastage allowance. Add extra for diagonal layouts, complex rooms or patterned work, and always keep a few spare tiles from the same batch for future repairs. Confirm the pieces-per-box figure on the actual packaging.
This calculator turns a room size into tiles and boxes: area ÷ tile footprint (including the grout joint), wastage applied, rounded up to whole boxes. All common Indian sizes are preset, from 100 mm mosaic to 1200 × 2400 mm slabs.
Once you know the tile count, the two numbers everyone forgets are adhesive and grout — the sibling calculators below estimate both from the same room, which no tile-brand calculator does.
Enter the floor or wall area (or length × width) in sq.ft or m².
Pick the tile size from the presets, or enter a custom size.
Set wastage — 5% straight lay, 10% with cuts, 15% for diagonal or pattern layouts.
Enter tiles per box (printed on the box label; commonly 4 for 600 × 600 mm).
Read off tiles and boxes to order.
| Tile size | Tiles per m² | Tiles per 100 sq.ft |
|---|---|---|
| 300 × 300 mm (1 × 1 ft) | ≈ 11.1 | ≈ 103 |
| 300 × 600 mm (1 × 2 ft) | ≈ 5.6 | ≈ 52 |
| 400 × 400 mm | ≈ 6.3 | ≈ 58 |
| 600 × 600 mm (2 × 2 ft) | ≈ 2.8 | ≈ 26 |
| 600 × 1200 mm (2 × 4 ft) | ≈ 1.4 | ≈ 13 |
| 800 × 800 mm | ≈ 1.6 | ≈ 15 |
Simple area division, before joints and wastage — the calculator includes your joint width for the exact count.
| Layout | Wastage | Why |
|---|---|---|
| Straight lay, large plain room | 5% | Few cuts, most offcuts reusable |
| Rooms with cuts, borders, columns | 10% | More cuts, fewer reusable offcuts |
| Diagonal / herringbone / pattern | 15% | Every edge tile is cut at an angle |
Always order the full quantity in one lot — tile shade varies between production batches, and a top-up box from a different batch rarely matches.
Straight lay — the baseline. Cuts only at two walls; most offcuts reusable on the opposite side. 5% covers it.
Diagonal — every perimeter tile is an angled cut and the triangles rarely reuse. Budget 12–15%.
Herringbone / basket weave — cuts at every field edge plus pattern part-pieces. 15%, more in small rooms where the perimeter dominates.
Large format in small rooms — a 1200 mm tile in a 7 ft bathroom is mostly cuts; wastage can pass 20% and the offcuts are unusable. Sometimes the smaller tile is the cheaper floor.
One batch, one order — batch number and calibration are printed on the box; make the retailer pull all boxes from the same batch.
Keep 2–3 tiles aside after laying, labelled — the future repair that matches is worth more than the shelf space.
Count skirting as tiles — running feet ÷ tile length, with one tile yielding 3–4 strips.
Check boxes on delivery for corner chips before signing — transit damage found later comes out of your wastage margin.
120 sq.ft = 11.15 m² → with 10% wastage ≈ 12.3 m².
12.3 ÷ 0.36 m² per tile ≈ 34.1 → 35 tiles.
35 ÷ 4 per box = 8.75 → whole boxes.
5% for a straight lay in a simple room, 10% when there are cuts around fittings and doorways, 15% for diagonal or pattern layouts and very large formats. Under-ordering is worse than over-ordering — a later batch may not match in shade.
Commonly 4 tiles (1.44 m²) per box in the Indian market, but it varies by brand and thickness — check the box label and enter the real number in the calculator.
Yes — skirting is cut from full tiles, so count the running feet of skirting, divide by your tile length for pieces, and typically one tile yields 3–4 skirting strips. Add those tiles on top.
Tile shade and calibration vary slightly between production batches. Ordering everything at once (with proper wastage) keeps the whole floor from one batch — mixed batches show as visible shade patches.
