Geometry
Many small rooms or angled layouts can create more cuts than a large rectangle.
Pattern
Herringbone, diagonal and other patterns can increase material usage.
Product format
Roll goods, planks, tiles and modular carpet create different waste patterns.
Attic stock
Future repair stock should be planned separately from installation waste because exact colors and collections may later be unavailable.
Commercial flooring decisions depend on the actual substrate, moisture conditions, traffic, cleaning regime, accessibility requirements, fire/building rules, manufacturer instructions and local code. This site is for planning and comparison, not installation instructions.
