Rolls to buy
Whole quantities are rounded up.
How it's calculated
Effective roll area = (roll width − side overlap) × roll length. Rolls = area with waste ÷ effective coverage, rounded up.
Calculations use consistent units for your selected measurements. The waste allowance is applied once to the measured requirement. Whole purchase quantities are rounded up.
What this estimate includes
This is not a cutting plan. Room dimensions, pile direction, seams and pattern repeats can increase actual carpet requirements.
Quantity and arithmetic estimates only. Use project specifications for installation and design requirements.
