Frequently Asked Questions
Is 10% waste enough for flooring?
Ten percent is a common planning number for straightforward rooms, but complex layouts, stairs, patterns, and diagonal installs may need 15% or more.
Should I buy extra flooring for repairs?
Usually yes. Extra material can help with future repairs when a product color, texture, or dye lot is no longer available.
Does waste include damaged subfloor or underlayment?
No. This calculator estimates finish flooring material only. Underlayment, trim, adhesives, and subfloor repairs should be estimated separately.
