The hardest hardwood flooring species are ranked by their Janka hardness rating, which measures dent resistance and impact durability. Among common residential hardwood options, Cumaru ranks extremely high at approximately 3540, followed by Brazilian Cherry (Jatoba) at approximately 2350. Acacia typically ranges between 1700 and 2200 depending on species variation, while Oak measures between 1290 and 1360. Harder wood species generally offer better resistance to denting from furniture and foot traffic, making them suitable for high-use residential spaces.

Hardwood hardness is measured using the Janka hardness test, which calculates the force required to embed a steel ball into the wood surface.
Factors influencing hardness include:
Denser woods typically result in higher Janka ratings. Explore the refined grain and versatile finish options of white oak flooring, a top choice for modern and traditional interiors.
Each species is selected for performance, milling precision, and grading consistency.
