Floor Tile Calculator: Estimate Cost, Cement & Wastage

Measure room length × width to get total area. Divide by the area of one tile. Add 10% for wastage (15% for diagonal layouts). Example: 15ft × 12ft room = 180 sq ft. With 2×2ft tiles (4 sq ft each): 180/4 = 45 tiles + 10% = 50 tiles.

Add 10% for straight layouts in regular rooms. Add 15% for diagonal (45°) patterns. Add 20% for complex patterns like herringbone. Add 5–10% extra for bathrooms due to cutting around fixtures. Always buy slightly more than calculated.

There are exactly 11.11 300x300mm tiles in one square metre. For 600×600mm tiles, it is 2.78 tiles. For 400×400mm tiles, it is 6.25 tiles.

Common tile sizes in India: 300×300mm for bathrooms, 600×600mm for living rooms and bedrooms, 800×800mm for large spaces, 300×600mm for walls. Vitrified tiles (600×600mm) are the most popular for Indian homes.

Tile cement and adhesive consumption depends on tile size. For 600×600mm tiles on a smooth concrete floor, use approximately 3–4 kg of adhesive per sq metre. For traditional mortar bed, use a 1:4 cement-sand mix, requiring about 11 kg cement per square metre.

Vitrified tiles are fully fired with very low water absorption (< 0.5%) and high durability — best for high-traffic areas. Ceramic tiles are less dense, suitable for walls and low-traffic floors. Porcelain is a type of vitrified tile with the highest hardness, ideal for outdoor and commercial use.

Measure the room area normally (length × width). Then subtract the door threshold areas: standard door width is 0.9m × 0.1m = 0.09 m² per door. For practical purposes, door areas are often included in calculations as they result in very small differences.

Indian marble costs ₹60–₹150 per sq ft for material. Installation charges add ₹30–₹60 per sq ft. Total cost including cutting, polishing, and installation ranges from ₹100 to ₹1000+ per sq ft. You can use our floor tile calculator to estimate the total cost for marble slabs.

For traditional mortar bed (dry or wet): use a 1:4 cement-sand mix at 40mm thickness. Per sq metre: approximately 11 kg cement and 44 kg sand. For thin-set adhesive: approximately 3–5 kg of polymer tile adhesive per sq metre at 6–10mm thickness.

Yes. The flooring calculator works for all hard flooring materials — tiles, marble, granite, quartzite, and vinyl tiles. Enter the area and tile size.

Measure each tread (horizontal surface) and each riser (vertical surface) separately. Tread: width × depth. Riser: width × height. Multiply by number of steps. Add 15% wastage for cuts. Stair nosing (front edge) requires additional cut tiles or bullnose tiles.

Grout consumption depends on tile size and joint width. For 600×600mm tiles with 3mm joints, use approximately 0.5–0.7 kg of grout per sq metre. For 300×300mm tiles with 2mm joints, use approximately 1–1.5 kg/m². Use a grout calculator for precise estimates.

Calculate total area in m² (including wastage). Divide by 1.5 (box coverage). Round up to the next whole number. Example: 25 sq m room + 10% wastage = 27.5 m² ÷ 1.5 = 18.3 → purchase 19 boxes.

Diagonal (45°) tiling makes a room look wider and is a design choice, but requires 15% more tiles due to cutting. Straight (90°) layout is more economical. For small rooms or bathrooms, diagonal placement can create an illusion of more space.

Vitrified tiles are the most popular — durable, low-maintenance, and scratch-resistant. Marble is premium but requires polishing. Granite is hardest and most durable. Wooden/vinyl flooring is gaining popularity for bedrooms. Cement tiles are trending for heritage and rustic looks.

Divide the L-shape into two rectangles. Calculate area of each rectangle separately. Add the two areas. Apply wastage percentage. Example: 10×8 ft = 80 sq ft + 5×6 ft = 30 sq ft = 110 sq ft total, then add 10% wastage = 121 sq ft of tiles.

High-quality vitrified tiles last 20–30+ years with proper maintenance and no polishing needed. Marble can last 50–100+ years but requires periodic polishing (every 3–5 years) and is prone to staining and etching from acids. Both are excellent choices for Indian climate conditions.

Divide the room into regular rectangles, triangles, or semicircles. Calculate each area separately and sum them. For triangles: 0.5 × base × height. For semicircles: 0.5 × π × r². Always add extra wastage (15–20%) for irregular rooms due to more cuts required.

For vitrified tiles: 1.5–3mm joint width. For ceramic tiles: 3–5mm. For stone/marble: 1.5–3mm. Wider joints are more forgiving for uneven tiles. Narrow joints look modern and minimalist. Use matching grout colour for seamless appearance or contrasting grout as a design feature.

For a 1000 sq ft house, deduct walls and pillars (approx 10%), leaving 900 sq ft. Add 10% for tile wastage using our tile wastage calculator, yielding 990 sq ft. For 2x2 ft (600x600mm) tiles, you will need exactly 248 tiles.
