Density table (approx., at 12% MC)
| Species | Density (kg/m³) | Feel |
|---|---|---|
| Balsa | 160 | Very light |
| Pine | 520 | Light |
| Plywood | 620 | Light–medium |
| Walnut | 640 | Medium |
| Beech | 690 | Medium–hard |
| Maple | 710 | Hard |
| Oak | 720 | Hard |
| MDF | 760 | Heavy panel |
| Melamine | 780 | Heavy panel |
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.
