Guide de densité et poids du bois

Density table (approx., at 12% MC)

Weight of a board

Weight (kg) = length × width × thickness (m) × density

A 2 × 0.2 × 0.05 m oak board (720 kg/m³):

Weight = 2 × 0.2 × 0.05 × 720 = 14.4 kg

Why density matters

• Strength and weight usually track density — denser wood is stiffer.
• Shipping cost scales with weight.
• Denser woods need bigger pilot holes and sharper blades.

Practical tips

• Density changes with moisture: a board at 20% MC weighs more than at 8%.
• The table is approximate — regional and growth-rate variation is normal.
