Method

How the calculation works

PlanCalq divides the project area by the face area of one tile to estimate the minimum tile count, then rounds up to a whole tile.

Waste is added to cover cuts, breakage and layout losses. The final tile count is then converted into full boxes so the result reflects what you actually need to purchase.

Calculation summaryProject area ÷ tile area = tiles requiredRequired tiles + waste allowance = recommended tilesRecommended tiles ÷ tiles per box = boxes to buy (rounded up)
Common questions

Tile Calculator FAQs

Is 10% tile waste enough?

Ten percent is a common planning allowance for straightforward layouts. Complex patterns, diagonal cuts, fragile materials or many corners may justify a higher allowance.

Why are boxes rounded up?

Retail tile is normally sold in complete boxes. The calculator therefore rounds to the next full box even if the exact tile count is slightly lower.

Can I use this for wall tile?

Yes, as long as the length and width you enter represent the wall area you want to cover.
