Quick answer
Tiles needed = room area × (1 + wastage) ÷ area of one tile. A 12 × 10 ft room is 120 sq ft. With 600 × 600 mm (2 × 2 ft) tiles of 3.88 sq ft each and 10% wastage, you need 35 tiles, or 9 boxes of 4. Use 10% wastage for straight laying and 15% for diagonal patterns or rooms with many corners.
How to use this calculator
- Measure the room's length and width in feet, wall to wall.
- Pick the tile size and enter how many tiles come in one box.
- Choose wastage for cuts and breakage, then buy all boxes from one batch.

These are typical figures for Indian homes. Check the product spec sheet, and ask an electrician or installer before you buy or fit anything.
