How Carpet Estimating Works
Carpet is commonly supplied from a fixed-width roll. This calculator checks both room orientations and chooses the lower-material layout before applying an additional waste allowance.
Important Limitation
Seams, pattern matching, stairs, closets, doorways, and installer layout can change the final quantity. Use this result as a planning estimate and confirm the cut plan with the supplier or installer.
Calculation Standards
This tool uses documented formulas and high-precision internal values. Displayed results may be rounded for readability. Review the assumptions and verify important decisions with a qualified professional.
