Frequently Asked Questions
Measure the length and width of the room in feet. Multiply them to get the area. Add a waste factor (usually 5-10%) to account for cutting and mistakes.
The waste factor is an extra percentage of material added to cover errors, cuts, and pattern matching. Typically 5-10% for standard rooms, but may be higher for irregular shapes or diagonal installations.
Check the product packaging or manufacturer specifications. It is usually listed as square feet per box, plank, or tile.
