Wood wall art is one of my favorite types of decor. I love that you can get so creative with your designs while adding in some warmth to your spaces through the wood. Not only does it make a space feel more complete, it’s not too difficult to make!
This set of geometric wood wall art is actually a duplicate of the exact same design. One is just hung upside down! I love that this pattern’s clean lines give it a modern feel.
Alright, let’s start DIYing!

What You’ll Need
How to Make Geometric Wood Wall Art
STEP 1: SAND
Before cutting anything down, go ahead and sand your boards. It’s much easier to knock out the sanding now before everything gets cut down into small pieces. We sanded everything with 120, 180, and 220 grit sandpaper.
STEP 2: CUT PIECES
Start by cutting your plywood pieces down to 15×19. This will allow your final wall art to be 16×20″.
Next cut the majority of your pieces roughly down to size. You don’t have to measure exactly here, but err on the side of being too long. We’ll cut off the overhang at the end. Here’s how we cut ours (the quantities reflect what’s needed for 2 art pieces):
- Straight on both ends: 4 @ 20″, 8 @ 5″
- One side angled at 22.5-degrees: 8 @ 13″, 2 @ 9″, 2 @ 7″, 4 @ 5″
- One side angled at 45-degrees: 2 @ 19″, 8 @ 5″, 6 @ 9″
There are 8 pieces per art piece that do need to be accurately measured. They are all cut at 90-degrees on one side and 45-degrees on the other. The measurements provided are measuring the LONG side in inches.
- 1.5, 3, 4.5, 6
- 1 13/16, 3 5/16, 4 13/16, 6 5/16
The first set of measurements are the pieces highlighted in red, while the second set are for the pieces highlighted in orange.
STEP 3: STAIN
Before staining, I applied pre-stain to each of my boards to help ensure a more even finish. Pine boards are notorious for being splotchy, so I like to add in this extra step for more consistent coloring.

STEP 4: GLUE
Before you start gluing, I’d recommend laying out your pieces into sections so that you can quickly move through the pattern without fumbling when trying to find your next piece.
I would also recommend starting with the piece that is highlighted in yellow. It should be placed 6″ from the edge of your plywood. From there, you can decide what order to apply your boards in.
Apply an even bead of glue to one board at a time and place it where you want it to be. Apply slight pressure to the board for a 15-30 seconds before adding the next piece. Think of it like a Command Strip. You have to press it down for a bit before moving on.
You can also add a piece of painter’s tape to help keep it in place or you can pop a nail or two into each piece. If you add nails, just remember that you’ll probably want to go back and fill in all the nail holes at the end.
As you place each piece, be careful to not adjust any of the pieces you previously glued down. You can use any of your 1/2 x 3/4″ boards as a spacer.
Once your glue has dried for approximately 15 minutes, grab a screw and a clean cloth and wipe off any glue that seeped out. Poking a screw through the cloth allows you to get into tight corners that you wouldn’t normally be able to get into.
Let your glue dry for 24 hours before moving onto the next step.
STEP 5: CUT OFF EXCESS
Add a piece of painter’s tape to the front of your wood art to help prevent the wood from splintering as you cut through it.
We used our Kreg Accu-Cut to get a clean, straight line all the way across. You want to cut your wall art so that the decorative pieces are exactly in line with your plywood edge.
STEP 6: ADD FRAME
Cut your frame pieces down to size and attach them using glue and 1/2″ brad nails.
If you would like to fill your nail holes, you can use Early American wood putty for a great color match and no-sanding required.
STEP 7: SEAL
We opted to seal ours with spray Polycrylic because it dries crystal-clear and doesn’t alter the color of your wood.
There you have it! Now you have yourself some DIY geometric wall art. The great thing about this wall art is that it has limited possibilities. You can get creative with the pattern and still use the same technique to make your design a reality!
