You’ve got the plan. You’ve got the tools. You’re ready to build.
Then you walk into the lumber section…and freeze.
Suddenly you’re staring at stack of boards with numbers, acronyms, and price tags that make no sense. What’s the difference between 1x4 and 2x6? Why are some boards so rough? What even is a board foot.
If this sounds familiar, you’re not alone. The good news? Buying wood doesn’t have to feel like learning a new language.
Let’s break it down and take the mystery out of the lumber aisle.
Step 1: Know the Two Main Categories:
These are the two types of wood you’ll see most often:
Hardwoods
Come from slow-growing trees (oak, walnut, maple)
Stronger and more durable
Often used for furniture and decor
More expensive
2. Softwoods
Come from fast-growing trees (pine, fir, cedar)
Easier to cut, drill, and sand
Great for beginners and budget builds
Sold in most big box stores
Step 2: Decode Lumber Sizes
If you see wood marked as 1x4, 2x6, etc. it’s referring to nominal dimensions (not the actual size)
For example
1x4 = actually 3/4” x 3 1/2”
2x4 = actually 1 1/2” x 3 1/2”
Why? Because lumber is cut rough, then planed down, and the label sticks with the “rough” size. Yep - it’s confusing, but you get used to it.
Step 3: Look for “S4S” for Smooth Cuts
When wood is marked S4S, that means it’s “surfaced on four sides” - aka it’s been smoothed and squared and is ready to use.
Perfect for beginners!
Other terms to look for:
Kiln Dried (KD) - more stable, less warping
Pressure Treated - For outdoor use only (can be toxic indoors)
Common Board - Often pine; affordable and beginner friendly
Step 4: Ask for Help - and Don’t Apologize for It
If you’re unsure about what you need, it’s absolutely okay to ask someone at the store. You don’t have to prove anything.
Here’s a tip:
“Hi! I’m working on a small shelf. I need wood that’s easy to cut and paint. Can you point me in the right direction?”
You’ll usually get great help - and maybe even a few extra tips!
Step 5: Buy Extra (Mistakes Happen!)
Always buy at least 10-15% extra for mistakes, knots, or changes in your project. There’s no shame in needing a second chance cut.
Third Shift Takeaway:
You don’t need to memorize every type of wood or master grain direction overnight. Start simple. Stay curious. And remind yourself: you belong in that lumber aisle.
