What is beech wood?

Broadleaf wood · referenceBeech wood
One of the most widely used hardwoods in Europe: strong, fine-grained and so bendable after steaming that a whole furniture style grew out of it.

Beech at a glance
Pale yellow to reddish brown, with a straight grain and a smooth, fine texture. Few or no knots, which gives it a strikingly uniform appearance.
Beech is heavy and dense — at 720 kg/m³ as heavy as oak — and you notice that in everything: it hardly wears, it holds screws and it gives a clean, even surface. That is exactly why you find it in stairs, worktops, kitchen utensils and toys.
And then there is the one property that makes beech unique: after steaming it can be bent without breaking. That property underlies the classic bentwood café chair, and almost every curved piece of furniture you know.

To be fair: beech moves a lot with changes in moisture and does not belong outdoors. This is an indoor wood, full stop.
Up to 40 metres and three centuries old
The European beech (Fagus sylvatica) grows 30 to 40 metres tall, with a straight, cylindrical trunk that can reach a metre and a half in diameter — hence the wide, knot-free boards. Beeches easily reach three hundred years; some reach four hundred.

The mother of the forest
Beech is widespread in Europe and grows mainly in temperate regions, on moist, well-drained soils.
30 to 40 metres tall
With a straight, cylindrical trunk that can reach a metre and a half in diameter — hence the wide, knot-free boards.
Three centuries old
Beeches easily reach three hundred years; some specimens reach four hundred.
The American relative
Besides the European beech there is the American beech (Fagus grandifolia), with comparable properties.
The word "beech" goes back to the Old English bōc, which also means "book" — early books were made from thin slices of beech wood. And beechnuts are edible; they used to be fed to pigs, which gave the meat a prized flavour.
Technical properties
| Property | Value | What that means |
|---|---|---|
| Density | ±720 kg/m³ (12% moisture) | Heavy and dense — as heavy as oak |
| Bending strength | 110 N/mm² | Very high; hardly deflects under load |
| Radial shrinkage | 0.3–0.5% | Limited in one direction… |
| Tangential shrinkage | 1.3–1.7% | …but three to four times as much in the other — hence the movement |
| Durability class | Class 5 | Not durable: less than five years outdoors, untreated |
| Distinctive | Steam-bendable | Can be bent after steaming without breaking |
A board that shrinks three times as much in one direction as in the other starts to warp as soon as the humidity changes. Keep it between 40 and 60% indoors and don't put beech right next to a radiator — then it behaves.
What beech is used for
Everywhere indoors where hardness, a fine surface and a neutral colour come together.
Furniture
Chairs, tables and cabinets — and thanks to steam bending, anything with a curve.
Floors and stairs
Its hardness and uniform appearance make beech a classic choice for heavily trodden surfaces.
Kitchen utensils
Chopping boards, spoons and spatulas: dense, odourless and free of resins that give off flavour.
Toys
Splinter-free, strong and safe — the reason wooden toys are so often made of beech.
Worktops
A thick beech worktop is almost indestructible, and you can always sand it again.
Why beech doesn't belong outdoors
This is not a detail but the most important limitation of this species.
Beech is in durability class 5, the lowest on the European EN 350 scale. Untreated and outdoors it is attacked by fungi and insects within a few years — even faster than spruce. And its strong movement with changes in moisture doubles the problem: the wood warps, cracks and lets water in.
If you are looking for a wood with comparable hardness that can go outdoors, look at robinia — which reaches class 1 to 2 — or at teak.
We don't work with beech. Our furniture is made of pressure-treated spruce, Douglas fir, teak and other hardwood. Beech is in our register because you come across it everywhere indoors and it deserves a good explanation.
Frequently asked questions about beech wood
Can beech go outdoors?
Why is beech used for bentwood furniture?
Because after steaming it bends exceptionally well without breaking. That property underlies the classic bentwood café chair — and almost every curved wooden piece of furniture.
How heavy is beech wood?
About 720 kg/m³ at 12% moisture content — as heavy as oak and considerably heavier than softwood. You won't lift a beech worktop on your own.
Why does beech move so much?
It reacts strongly to changing humidity: tangential shrinkage is three to four times the radial. Keep indoor humidity stable between 40 and 60%.
Is beech a hardwood?
Yes, botanically: it comes from a broadleaved tree. But hardwood says nothing about durability — beech is the textbook example of a hardwood that has no business outdoors. See hardwood or softwood.
Beech in perspective
Beech is a reference species in our register — wood we don't work with, but do know.
