About Janka Database Tool
The Janka hardness test measures the force needed to embed a 11.28mm steel ball to half its diameter into wood - a direct measure of a wood's resistance to denting and wear. It is the universal benchmark for choosing flooring and furniture timber. This tool gives the Janka rating for 60 species in both US (lbf) and metric (Newtons) units, with a side-by-side comparison and suitability guidance.

Frequently Asked Questions
What Janka rating do I need for flooring?
For residential floors, 1000+ lbf is comfortable (oak is ~1290). For busy households with pets or commercial use, aim for 1400+ (hard maple ~1450, teak ~1070-2330 depending on type). Very high Janka woods like Ipe (3680) are extremely dent-resistant but harder to work and install.
Is a harder wood always better?
No. Higher Janka means more dent and wear resistance, but very hard woods are harder to cut, machine, nail and sand, and can be more brittle. For furniture and joinery, a medium-hard wood is often the best balance of durability and workability. Match hardness to the actual use, not just maximise it.
Why give both lbf and Newtons?
The US and Indian trade typically quote Janka in pounds-force (lbf), while European specifications and the EN 1534 standard use Newtons. Importers and exporters need both. This tool shows each species in both units so you can communicate hardness clearly with any partner worldwide.
