Choosing Between Softwood vs. Hardwood
In general, wood is classified into softwood and hardwood. Softwood lumber comes from conifer trees such as pine, cedar, spruce, and fir. It can easily be dented with only a fingernail. Also, it absorbs and loses moisture easier than hardwood. Thus, it requires extra care to keep its stability. Compared to hardwood, softwood is cheaper is conifer trees tend to grow faster than hardwood trees.
Meanwhile, hardwood lumber comes from deciduous trees with broad leaves. Walnut, oak, maple, and mahogany are the most common sources of hardwood lumber. Hardwood is harder than softwood and it is not easily dented.
In the world of lumber, wood sellers may refer to wood as green. Green wood means that the wood has just been cut. Often, this wood has high moisture content. And while it works perfectly well on some projects, it doesn’t for most projects. Because of this, you might want to avoid it as it easily warps and splits. Instead, try to browse through options for Hardwood cut stock as the cuts have been allowed to dry for a while, making them more durable than green wood.
Surface versus Unsurfaced

Although the majority of people love surfaced lumber, others choose unsurfaced. The choice depends on your preference and the task at hand.
Lumber grades are more about quality and look. They are also stamped on the lumber, along with moisture ratings. Often, the grades in the form of A, B, C, and D, with A being the highest grade. The A grade has the least number of knots or imperfections while D has the least quality with the greatest number of imperfections. Talk to the dealer to know the best grade for your project.
