Frequently asked questions
How many tiles for a 12 m² room in 60 × 60?
12 m² with a 10% allowance is 13.2 m², i.e. 37 tiles of 0.36 m². Always plan one extra box for cuts and breakages.
What allowance for each laying pattern?
5% is enough for a straight lay in a simple room, 10% covers typical cuts, 15% is needed for a diagonal lay or a room with many angles.
Should I include skirting and thresholds?
No: this covers the floor area only. Skirting boards, thresholds and step nosings are counted in linear metres and added separately.
