What is the moisture content of wood?

The moisture content of wood is a critical factor that influences its physical properties, including strength, weight, and durability. In general, the moisture content of seasoned wood, which has been properly dried, typically ranges from about 15% to 20%. A moisture content around 19% indicates wood that is in a suitable condition for many construction and manufacturing applications, striking a balance between workability and stability.

When wood is dried to this level, it has successfully removed a significant amount of moisture without making it too dry, which could lead to cracking or splitting. This value is often referenced in standards and guidelines for woodworking and construction, making it a common point of understanding for those working with wood in various capacities.

Higher moisture contents, like those represented in the other options, may suggest that the wood is still somewhat "green" or has not been dried adequately, which could affect its quality and usability in structural contexts. Therefore, 19% is recognized as the optimal moisture content that aligns well with both the practical needs and industry standards for dry wood.
