12 m² takes about 65.7 tiles laid edge to edge; with 10% for cuts and breakage buy 73 tiles, which is 10 boxes of 8. The joints need about 2.6 kg of grout.

गणना कैसे होती है S
  1. क्षेत्रफल

    A=4×3=12 m2A = 4 \times 3 = 12\ \text{m}^2
  2. Area one tile covers, including its joint

    (600+3)(300+3) mm2=0.182709 m2(600 + 3)(300 + 3)\ \text{mm}^2 = 0.182709\ \text{m}^2
  3. Tiles with waste

    120.182709×(1+0.1)=72.246031⇒73\frac{12}{0.182709} \times (1 + 0.1) = 72.246031 \Rightarrow 73

    Rounded up to whole tiles.

  4. Boxes

    ⌈738⌉=10\left\lceil \frac{73}{8} \right\rceil = 10

    Rounded up to whole boxes.

  5. Grout (Mapei consumption formula)

    600+300600×300×9×3×12=1.62 L×1.6=2.592 kg\frac{600 + 300}{600 \times 300} \times 9 \times 3 \times 12 = 1.62\ \text{L} \times 1.6 = 2.592\ \text{kg}

    Lengths in mm give litres of joint per m². 1.6 kg/L is Mapei's factor for cementitious grout; the estimate has no waste added.

Flooring and tile calculator के बारे में

The tile count is the area divided by the area one tile covers with its grout joint, (tile length + joint) × (tile width + joint). A waste allowance for cuts and breakage is added, then the count is rounded up to whole tiles and whole boxes. Grout volume per m² is (A + B) ÷ (A × B) × tile thickness × joint width, with A and B the tile sides and all four in millimetres.

The default 4 × 3 m floor in 600 × 300 mm tiles with 3 mm joints takes 65.7 tiles laid edge to edge. With 10% waste that is 73 tiles, or 10 boxes of 8, plus 1.62 L of grout (2.6 kg).

The waste presets are this calculator's rules of thumb: 10% for a straight lay, 15% for diagonal and 20% for herringbone, which cut more tiles at the edges. The drawing shows a straight lay.

सवाल

How many tiles do I need per square metre?

Divide 1 m² by the area of one tile plus its joint. A 600 × 300 mm tile with a 3 mm joint covers 0.603 × 0.303 = 0.1827 m², so 1 m² takes 5.47 tiles; 300 × 300 mm tiles take 10.89. Multiply by the whole area before rounding up: rounding 5.47 up to 6 per m² would overbuy by about 10%.

How many tiles do I need for 100 square feet?

About 98 twelve-inch tiles before waste. A 12 × 12 in tile with a ⅛ in joint covers 12.125 × 12.125 in, or 1.021 ft², so 100 ft² takes 97.95 tiles. Adding 10% for cuts and breakage gives 107.7, rounded up to 108 tiles.

How much extra tile should I buy for waste?

This calculator's presets add 10% for a straight lay, 15% for a diagonal lay and 20% for herringbone, because angled layouts cut more tiles along every wall. On the default 12 m² floor those give 73, 76 and 79 tiles of 600 × 300 mm.

How much grout do I need?

Multiply (A + B) ÷ (A × B) by tile thickness and joint width, all in mm, to get litres of joint per m². For 600 × 300 mm tiles 9 mm thick with 3 mm joints that is 900 ÷ 180,000 × 9 × 3 = 0.135 L per m², or 1.62 L for 12 m². The calculator converts at 1.6 kg per litre; check the grout bag's own coverage table.

Do grout joints change the number of tiles needed?

Yes, they lower it slightly, because each tile plus its joint covers more floor. A 600 × 300 mm tile covers 0.18 m² on its own and 0.1827 m² with a 3 mm joint, so 12 m² needs 65.7 tiles instead of 66.7 before waste. For 50 × 50 mm mosaic with 3 mm joints, each tile's footprint grows by 12.4%.

“Flooring and tile calculator” कितना सटीक है?

सटीकता आपके इनपुट और विधि की मान्यताओं पर निर्भर करती है। दशमलव गणना 50 सार्थक अंकों का उपयोग करती है, लेकिन अनुमान, संख्यात्मक विधियाँ और स्रोत डेटा कम सटीक हो सकते हैं। दिखाए गए मानों को पूर्णांकित करने से ये सीमाएँ दूर नहीं होतीं। स्वतंत्र स्रोतों के हल किए गए उदाहरणों से जाँच: 3। उदाहरण के लिए, “4 × 3 m floor, 600 × 300 mm tiles, 3 mm joints, 10% waste” की जाँच Python decimal: 12 ÷ (0.603 × 0.303) = 65.68 × 1.1 = 72.25 → 73; grout (900/180000) × 9 × 3 × 12 = 1.62 L × 1.6 kg/L (Mapei formula); 10 boxes × 40 = 400 से की गई है।
