How to use it
- 01Enter the room length and width in meters.
- 02Provide the tile length and width in centimeters.
- 03Add tiles per box and a waste percentage so the result matches how material is actually purchased.
Result guide
- Floor area is the total surface being tiled before layout waste.
- Raw tile count is the perfect mathematical quantity without cutting loss.
- Box count rounds the final requirement up to full packs so procurement is easier.
About this calculator
Tile jobs need both piece count and packaging count because installers buy full boxes, not just a raw tile quantity. This page bridges that gap cleanly.
Waste matters even more with patterned or diagonal layouts, so a fast tile calculator is useful well before final material ordering.
Frequently asked questions
Why do I need a waste allowance for tiles?
Because edge cuts, breakage, pattern alignment, and future spare pieces all increase the quantity beyond the pure floor area calculation.
Does this work for wall tiles too?
Yes. The tile-count math is the same as long as you enter the total surface dimensions you plan to cover.
Why is box count rounded up?
Tiles are commonly sold in full boxes, so the practical buying quantity needs to round upward.
