Use this workshop calculation to turn measured dimensions and the selected construction convention into a cut, spacing, fit, or material-planning value.

Mass Kilograms (kg)

Required number input.

Volume Cubic Meters (m³)

Required number input.

Bulk density of wood at a specified moisture state from mass and volume measured at that same state. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Density Kg Per M3 (kg/m³)

The resulting density kg per m3 returned as a number.

• Nominal dimensions, kerf, moisture movement, hardware clearances, wall squareness, and manufacturer instructions can change the required shop dimension. Measure the actual assembly and test critical joints on scrap before cutting finished material.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Complement the calculated dimension with a physical story stick, dry fit, or full-size layout. Follow the hardware, coating, adhesive, or machine manufacturer's limits where they differ from a rule of thumb.

• Holz Darrdichte

  Oven-dry wood density from oven-dry mass and oven-dry volume; both measurements must be made after drying.

• Holz Gewicht Bei Feuchte

  Wood mass at a target dry-basis moisture content from its oven-dry mass.

• Holz Quellung

  Expected across-grain wood swelling over a rising dry-basis moisture content, using a species- and direction-specific measured movement coefficient.
