Wood Species Weight Chart (Dried)
When you need to know how heavy a stack of lumber is — for shipping, for a glue-up, or to check a floor load — species matters more than size.
| Species | lb per cubic foot (dried) | lb per board foot | Hardness |
|---|---|---|---|
| Teak | 52 | 4.33 | Very hard |
| Oak (white) | 48 | 4.00 | Hard |
| Mahogany | 35 | 2.92 | Medium |
| Birch | 43 | 3.58 | Hard |
| Maple (hard) | 42 | 3.50 | Hard |
| Cherry | 42 | 3.50 | Firm |
| Walnut | 41 | 3.42 | Medium |
| Ash | 47 | 3.92 | Hard |
| Douglas fir | 34 | 2.83 | Medium |
| Southern pine | 42 | 3.50 | Softwood, knotty |
| SPF (spruce-pine-fir) | 30 | 2.50 | Softwood |
| Cedar (western red) | 25 | 2.08 | Soft, rot resistant |
| Pine (SPF, framing) | 32 | 2.67 | Soft |
| Poplar | 29 | 2.42 | Very soft |
Green versus dry
Green lumber weighs considerably more. A green 4/4 board can be 30–50% heavier than the same board at 6–8% moisture content. Weight figures for shipping should be based on dried stock; for estimating wet weight add roughly half.
Worked example
20 board feet of kiln-dried white oak weighs 20 × 4.00 = 80 lb. If it arrives green, expect roughly 120 lb, and note that the glue-up will shrink slightly after drying — allow for movement in a panel glue-up.
