Wood Density: Weight of 1 m³ of Timber and Density Table

A board is a sawn timber product manufactured by longitudinally cutting logs. When calculating the weight of wooden structures, wood density is the primary value used because it determines the weight of one cubic meter of material.

Wood Density Table

Although many users search for “specific weight of wood boards”, the values below are wood density (kg/m³) at different moisture contents.

Weight Calculation

m = ρ × V

where m is mass, ρ is wood density (kg/m³), and V is volume (m³).

Wood Density

Wood density depends mainly on the species and moisture content. The higher the moisture content, the greater the weight of one cubic meter.

Conclusion

Depending on the species and moisture content, wood density typically ranges from 380 to 1330 kg/m³. Use the values in the table for engineering and construction calculations.

Frequently Asked Questions

Can the density of wood board be used for precise calculations?

The density and weight values for wood board in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.

Why can the actual weight of wood board differ from the table?

The actual weight of wood board depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.

How do you calculate the mass of wood board from density?

For an approximate calculation, use the formula: mass = density × volume. If the density of wood board is given in kg/m³ and the volume is in m³, the result will be in kilograms.
