Western Red Cedar Lumber Weight Chart
Western Red Cedar (WRC) is known for its strength, durability, and lightweight, making it a popular choice for various construction and woodworking projects. The weight of WRC lumber can vary depending on its size, moisture content, and whether it’s in its nominal or actual dimensions.
General Weight Information
- At 12% moisture content, WRC weighs approximately 21–23 PCF or 1.75–1.92 BF.
- When green (higher moisture content), WRC weighs approximately 30–32 PCF or 2.5–2.67 BF.
Per Cubic Foot (PCF) Board Foot (BF)
The chart lists weights per 1-foot (12") length. The values are based on lumber with an approximate 12% moisture content.

Understanding Nominal vs. Actual Sizes
Nominal lumber sizes are the dimensions by which lumber is generally referred to in the industry. However, the actual dimensions are smaller due to milling and finishing processes. For instance, a nominal 4"x4" WRC timber will actually measure closer to 3.5"x3.5". The same principle applies to all other nominal dimensions. Understanding the difference between nominal and actual sizes is important for planning and calculating accurate material needs.
Factors Affecting Weight
- Moisture Content: The weights above are based on lumber at approximately 12% moisture content. Higher moisture content (green lumber) will result in heavier pieces.
- Grade and Treatment: Different grades and any treatments applied to the wood can slightly influence the overall weight.
Western Red Cedar is favored not just for its light weight but also for its resistance to decay, dimensional stability, and ease of handling. Whether for a residential project or a larger-scale application, knowing the weights for both nominal and actual dimensions ensures accurate material estimation and transportation planning.
