When it comes to buying lumber for your next project, it's important to understand the difference between nominal and actual sizes. Nominal size refers to the size of the board when it was first rough sawn, while actual size refers to the board's true dimensions after it has been processed and planed. Understanding this difference can save you a lot of frustration and ensure that your project comes out looking the way you want it to. In this blog, we will provide you with a dimensional lumber cheat sheet specifically for 1-inch-thick boards.
It's important to note that not all lumber follows this pattern. For example, pressure-treated lumber tends to have a greater difference between its nominal and actual sizes. Additionally, some hardwood lumber may be sold in its rough-sawn dimensions, so be sure to double-check with the supplier if you are unsure.
The standard dimensions of lumber, like a 2 x 4 or 4 x 4, refer to the width and thickness of the wood. But what about the length of the lumber? If you see an additional dimension included, such as 2 x 4 x 120, that third number indicates the length of the wood.
Understanding the difference between nominal and actual sizes can help you make informed decisions when selecting lumber for your next project. It can also prevent costly mistakes and ensure that your project comes out looking the way you intended. Remember this dimensional lumber cheat sheet when shopping for 1-inch thick boards, and you'll be able to confidently choose the right size for your needs.
