Frequently asked questions
How much extra should I buy?
About 10 % for normal layouts, up to 15 % for diagonal or complex patterns. Keep a few spare tiles for later repairs.
Does the calculation include grout joints?
No. Joints slightly reduce the number of tiles needed, which is covered by the waste reserve.
Can I use it for laminate and vinyl?
Yes. Enter plank length and width, or simply the m² per pack from the packaging.
