Cedar is generally harder than pine wood. This distinction is based on the wood's Janka hardness rating, which measures the resistance of wood to indentation. According to the Janka hardness scale, cedar wood typically ranges from 600 to 900 on the scale, while pine wood falls between 300 and 500. This indicates that cedar is harder and more durable than pine, making it suitable for applications requiring greater structural integrity and resistance to wear and tear.

The hardness of cedar can be attributed to its denser grain structure and higher oil content. These characteristics contribute to cedar's natural resistance to moisture, insects, and decay, making it a popular choice for outdoor furniture, decks, and siding. Pine, on the other hand, has a more open grain and lower oil content, which makes it softer and more susceptible to damage from moisture and insects. This softer nature of pine also makes it easier to work with, as it can be cut, nailed, and sanded more easily than cedar.

Data from the Janka hardness scale further supports this analysis. For instance, Western red cedar, a common type of cedar used in construction, has a Janka hardness rating of around 600, while southern pine, a common type of pine, has a rating of approximately 500. This difference in hardness is significant enough to impact the performance and longevity of products made from these woods. For example, a deck constructed with cedar will generally last longer and require less maintenance than one made with pine due to cedar's greater resistance to environmental factors.

In summary, cedar is harder than pine wood, primarily due to its denser grain structure and higher oil content. This inherent hardness makes cedar more durable and suitable for applications where resistance to wear, moisture, and insects is crucial.
