Janka 2,990 lbfThe species sets most of what you will live with on a wood floor: its colour and how that colour changes with light, how readily it dents, how much it moves with the seasons, and how it takes oil, lacquer or a colour treatment. Each profile below brings together published data for one timber, with a key-facts table and links to every source used.
Use the region filter to narrow the list, or the A–Z index to find a species by its common or scientific name. Trade names vary from country to country, so each profile lists the other names a timber is sold under.
We start with the species most widely sold as flooring and add more over time. Each profile shows the date it was last checked against its sources. Spotted something that needs correcting? Let us know through the contact page.
