Cedar is generally considered better for making cabinets compared to poplar. While both woods have their advantages, cedar offers superior durability, resistance to moisture, and aesthetic appeal, making it a more suitable choice for cabinet construction.

Cedar is a dense and durable wood that naturally resists moisture and decay, which is crucial for cabinets that are exposed to humidity and temperature fluctuations. This natural resistance to moisture makes cedar an excellent choice for kitchen and bathroom cabinets, where moisture control is essential. According to the Wood Species Council, cedar has a Janka hardness rating of 870, which is higher than poplar's rating of 470. This higher hardness means cedar is less prone to dents and scratches, contributing to its longevity as a cabinet material.

Additionally, cedar has a distinct aromatic scent that can be beneficial in areas like kitchens, as it can help mask odors. Its rich, warm color and grain pattern also add visual appeal to cabinets, enhancing the overall aesthetic of a space. Poplar, on the other hand, is a softer wood that is more susceptible to dents, scratches, and warping over time. While poplar is more budget-friendly and can be painted or stained to achieve a desired look, it may not hold up as well in high-moisture environments or over the long term.

In summary, cedar is the better choice for making cabinets due to its superior durability, resistance to moisture, and aesthetic qualities. Its higher hardness rating and natural resistance to decay make it a more reliable and long-lasting option for cabinet construction.
