How The Calculation Works
Formulas, material coverage assumptions, waste buffers, and rounding standards.
Carpet cannot be tiled; it is manufactured in fixed 12ft or 15ft wide continuous rolls.
If a room is 13ft wide and carpet is 12ft wide, two parallel cuts are required, creating a seam and cut remnant.
Total square footage is converted into standard Square Yards (1 sq yd = 9 sq ft) for pricing.
