Lumber vs timber vs wood: What’s the difference?
The answer? The distinctions between lumber, timber and wood largely depend on where you are in the world.

In the UK, New Zealand and Australia, timber refers to sawn wood as well as processed wood products used for purposes such as home construction, cladding, decking and furniture making. It’s available in a range of softwoods and hardwood species, each with their own aesthetic and technical properties. The word timber is also commonly used to describe timber-frame construction — the use of wooden beams and posts to create buildings.



To confuse things, timber usually has a different connotation across the pond. This is often a source of confusion; in the USA and Canada, the word timber refers to unprocessed wood, such as unharvested or recently-felled trees still with their bark.

The word ‘lumber’, on the other hand, is used to describe processed wood products used for furniture making, home construction and the like. So, essentially, lumber in the USA means timber in the UK.



Wood, on the other hand, is used to describe the fibrous substance that makes up a tree; the very thing that supports it when it’s in the ground, allowing growth and stability. Wood is easily understood as the structure that makes up a tree. Also, people often use the word wood loosely to refer to both lumber and timber; or even more generally to refer to things like ‘wood flooring’, ‘wood cladding’.
