FAQs
How much wastage should I allow?
Allow 10% for straight layouts in simple rooms and 15% for diagonal patterns or rooms with lots of cuts around fixtures.
Do I need spare tiles afterwards?
Yes — keep a few spare tiles from the same batch for future repairs, as dye lots vary between batches.
Does this include grout gaps?
Grout gaps are small enough to ignore for estimating; the wastage allowance comfortably covers them.
Can I use it for wall tiles?
Yes. Enter the wall length and height as the room length and width and the maths is identical.
Is my data sent anywhere?
No. The calculation runs entirely in your browser and never transmits or saves your entries.
