How this estimate works
The calculator applies: ceil(length x width x (1 + waste/100) / coverage). Keep measurements in one unit system and round up when suppliers sell whole units.
Limitations
Staggered seams, diagonal layouts, damaged boards, and future repairs affect the order.

How much waste should I use? Follow the flooring maker first; straight layouts often use less than diagonal ones.
