About this calculator
Ordering the wrong number of floor tiles means a second trip to the dealer or boxes sitting in the garage for years. Measure the room once, add a sensible wastage buffer, and you know exactly how many tiles and boxes to buy before the mason arrives.
This tile calculator takes room length and width in metres, your tile size in centimetres (most Indian vitrified tiles are 60×60 cm or 80×80 cm), a wastage percentage, tiles per box from the carton label, and an optional price per box. It returns tile count with wastage, whole boxes to order, and estimated material cost.
The math is straightforward: floor area divided by one tile's area, multiplied by (1 + wastage). Boxes round up because stores sell full cartons. For diagonal or herringbone layouts, push wastage to 15%. Deduct fixed furniture footprints manually if the tile runs under kitchen units. Pair with the [[square-footage]] calculator for odd-shaped rooms, the [[area]] calculator for L-shaped floors, and the [[paint]] calculator when you are finishing walls in the same space.
Common uses
- Planning vitrified or ceramic floor tiles for a bedroom or hall renovation
- Estimating box count before visiting a tile dealer in India
- Budgeting material cost for bathroom or kitchen flooring
- Checking whether leftover tiles from a prior job cover a new room
- Quoting tile supply for a small contractor job
Frequently asked questions
How much tile wastage should I add?
Use 10% for straight layouts on rectangular rooms. Go to 15% for diagonal patterns, small rooms with many cuts, or fragile natural stone. Large 80×80 cm tiles on open floors can sometimes work with 8%.
How do I calculate tiles for a 10×12 ft room?
Convert feet to metres (10 ft ≈ 3.05 m, 12 ft ≈ 3.66 m). Multiply for area ≈ 11.2 m². Divide by your tile area. A 60 cm tile covers 0.36 m², so you need about 31 tiles before wastage.
Should I buy extra boxes for future repairs?
Keep one full box after installation if storage allows. Batch and shade vary between production runs. A few spare tiles beat hunting for a discontinued colour five years later.
Does this include wall tiles?
The same formula works for wall area. Enter wall length as
What if my tiles are rectangular?
Divide room area by the area of one tile (length × width in metres). This tool assumes square tiles; for 30×60 cm planks, compute one tile as 0.30 × 0.60 = 0.18 m² and enter that area mentally or use the [[area]] tool first.
