Chestnut Wood Guide 2026
Castanea dentata
American Chestnut was once the most important hardwood in eastern North America before the devastating chestnut blight of the early 1900s. Today, Chestnut lumber is available primarily as reclaimed material salvaged from old barns, cabins, and fences. Its warm brown color, distinctive wormy character, and historical significance make it one of the most sought-after reclaimed woods for flooring, paneling, and rustic furniture.

How lumber sizes are described
- Rough (4/4, 8/4…)
- Hardwood thickness in quarters of an inch as sawn, before surfacing. 4/4 = 1" rough.
- Surfaced (S2S/S4S)
- Thickness after planing. 4/4 typically finishes at 13/16" or 3/4".
- Nominal vs. actual
- Construction lumber is sold by nominal size; a 2x6 measures about 1-1/2" x 5-1/2".
- Random width / length
- Most hardwood is sold as it comes from the log — widths and lengths vary within a range rather than being fixed.
Color & Grain
Color: Light to medium brown heartwood that darkens with age; wormy pieces show distinctive insect track patterns
Grain: Straight grain with a coarse texture; frequently shows worm holes and character marks in reclaimed stock
