Tile Calculator
Use this tile calculator to estimate tile quantities based on floor or wall area, tile size, and waste allowance.
What This Calculator Does
This calculator works out how many tiles you need by comparing the total area to the area of each tile, then adding waste allowance. It is useful for floors, splashbacks, bathrooms, and walls.
How to Use
- Enter the area length and width.
- Enter your tile dimensions.
- Add a waste allowance.
- Click calculate.
Example
If a floor area is 18 square metres and you are using 600 x 600 tiles with 10% waste, the calculator estimates how many tiles you need.
Why This Calculation Matters
Tile quantities can swing quickly when tile size changes. A fast estimate helps with ordering, quoting, and keeping waste within reason.
Common Mistakes
- Using nominal tile size instead of actual size.
- Forgetting cuts and breakage.
- Ignoring layout patterns that increase waste.
- Ordering too tightly with no spare tiles.
FAQs
Why add waste allowance?
Because cuts, breakages, and pattern matching all increase the number of tiles needed.
Can I use this for wall tiles?
Yes. It works for walls or floors as long as you enter the correct area.
What waste allowance is normal?
A common starting point is around 10%, but the job layout can change that.
