Board width, species and finish are three separate decisions in a timber floor
People choose a wood floor by colour and then live with the consequences of three specifications they never considered.

The points below about timber floors are ordered by how much difference they make, not by how often they get repeated.
What matters most
- Hardness varies enormously between species and predicts denting, not scratching.
- Wide boards move more with humidity than narrow ones.
- Oil can be spot-repaired; lacquer generally cannot.
Species sets hardness and movement
Hardness scales rank timber by resistance to indentation, and the range between a soft pine and a dense tropical hardwood is several times over. A soft floor dents under chair legs and dropped pans, which some people read as character and others as damage, and knowing which you are is the decision. Species also differ in how much they swell and shrink with humidity, which determines how much the gaps between boards open in a dry winter.
Hardness does not predict scratch resistance, which is mostly a property of the finish rather than the wood.
Board width is a stability decision
A wide board expands and contracts more across its width in absolute terms than a narrow one, so seasonal gaps are larger and cupping is more likely. This is why wide boards are almost always engineered rather than solid: the plywood core restrains the movement. Narrow strip flooring is more tolerant of a damp environment and of underfloor heating, at the cost of a busier appearance.
Wide boards make a small room read as calmer and larger because there are fewer lines, which is a real visual gain worth the constraint.
Solid, engineered and laminate are different products
Solid timber is one piece throughout and can be sanded many times, but moves most and dislikes underfloor heating. Engineered board is a real timber wear layer on a stable core, can be sanded as many times as the wear layer thickness allows, and suits underfloor heating.
Laminate is a printed image under a wear layer with no timber surface at all, cannot be sanded, and is a different category despite being sold alongside. The number that matters on an engineered board is the wear layer in millimetres, and it is often buried in the specification.
Finish determines how it lives
A hardwax oil penetrates the timber, leaves a low sheen, and can be cleaned and re-oiled locally without refinishing the whole floor. A lacquer sits on top as a film, resists spills better, and when it wears through it does so in patches that cannot be blended.
Oil needs periodic maintenance, typically an annual refresh in traffic areas, and looks steadily better if it gets it. A household that will not maintain a floor is better served by a lacquer, and a household that will is better served by oil.
What actually damages a wood floor
Grit carried in on shoes is the main abrasive, which is why a long doormat protects a floor more than any finish choice. Water standing at a joint — a dishwasher leak, a repeatedly wet patch by a door — causes swelling that is not reversible.
Furniture feet without felt pads cause most of the visible scratching in ordinary rooms. Direct sunlight fades and changes the colour of most timbers unevenly, so a rug left in place for two years leaves a permanent mark.
Taste is not the argument here; how a room performs is.
Underfoot and overhead
A timber floor over a joisted structure transmits impact noise to the room below far more than carpet does, which matters in flats and often features in lease conditions. Acoustic underlay reduces this substantially and is frequently a requirement in apartment buildings, so check your lease before specifying.
Floating floors sound hollower underfoot than glued or nailed ones, which is audible and rarely mentioned in showrooms. A timber floor also reflects sound within the room, so a hard-floored living room usually needs a rug to sound comfortable.
Everything above, in order of what to do first
- Species sets hardness and movement. Hardness scales rank timber by resistance to indentation, and the range between a soft pine and a dense tropical hardwood is several times over.
- Board width is a stability decision. A wide board expands and contracts more across its width in absolute terms than a narrow one, so seasonal gaps are larger and cupping is more likely.
- Solid, engineered and laminate are different products. Solid timber is one piece throughout and can be sanded many times, but moves most and dislikes underfloor heating.
- Finish determines how it lives. A hardwax oil penetrates the timber, leaves a low sheen, and can be cleaned and re-oiled locally without refinishing the whole floor.

The takeaway
Pick the finish for the maintenance you will actually do, and check the wear layer before the colour.
A room that is used will always beat a room that is finished.
Questions readers ask
Is engineered flooring worse than solid?
Not worse, different. It is more stable, better over underfloor heating, and available in wider boards. Its limit is the wear layer, which caps how many times it can be sanded.
How many times can a floor be sanded?
A solid board can typically take several sandings over its life. An engineered board with a two millimetre wear layer might take one; a six millimetre layer, three or more.
