Guide to Buying Hardwood Lumber: Understanding Measurement, Kiln Drying, and Lumber Types

Choosing the right hardwood lumber is essential for successful woodworking. Understanding how lumber is measured, dried, and prepared helps ensure your project turns out just right.

1. Lumber Measurement: What Does 4/4 Mean?
Hardwood is typically measured in quarters of an inch—called “quarters.” For example, 4/4 means 1", 5/4 is 1.25", and so on. Knowing this helps you select the right thickness for your project.

2. Kiln Drying: Why It Matters
Freshly cut wood has high moisture content, which can cause warping or cracking. Kiln drying removes excess moisture in a controlled environment, making the wood more stable and ready to use.

3. Rough Cut vs. S2S Lumber vs S4S Lumber
Rough Cut lumber is unfinished and retains its natural edges and texture. It gives you flexibility in shaping and sizing but requires more prep work.

S2S (surfaced on two sides) lumber is planed smooth on the top and bottom faces, while the edges remain rough. This makes it easier to work with than rough cut while still giving you the freedom to square and size your own edges. This is what we typically sell.

S4S (surfaced on four sides) lumber is planed smooth and has two straight edges. It is ready to use, ideal for those with limited tools and time.

In Short:
Understanding quarters, kiln drying, and the difference between rough, S2S, and S4S lumber will help you make confident buying decisions and set your woodworking projects up for success.
