DIY Dining Table Build

Build a DIY Outdoor Dining Cedar Table

If you’ve looked at outdoor dining tables recently, you already know they can cost $5,000+. I wanted something oversized, clean, and built for hosting, so I decided to build one myself.

This design is simple but intentional. It’s a large-format table made from cedar that’s meant to live outside, handle the elements, and still look good doing it. The proportions are based on my space, but you can easily adjust the size to fit your setup.

This is one of those builds that doesn’t just look good, it completely upgrades how you use your backyard.

The recommended length is around 10 ft, but feel free to scale it depending on your space.

Materials

• 2 x 6 x 10 Cedar Board (Qty. 11)
• 2 x 6 x 8 Cedar Board (Qty. 1)
• 6 x 6 x 10 Cedar Board (Qty. 1)

• Clamps
• Wood Chisel Set
• Stain Pad + Extension Pole
• Exterior Wood Stain (I used Cabot – Acorn)
• Wood Glue
• Wood Screws
• Sandpaper (80, 120, 150, 220 grit)

Power Tools

• Cordless Drill
• Miter Saw
• Circular Saw
• Palm Sander
• Oscillating Tool

Step 1: Build the Tabletop

Start by laying out your 2 x 6 Boards side by side.

Arrange them in an alternating grain pattern (smile/frown) to help prevent warping over time.

What matters here:

Keep your edges tight and consistent
Plan your grain so it looks intentional
Trim edges if needed for a clean final width

Final tabletop length should land around 120 inches.

Tip: Cut boards together when possible so everything lines up perfectly.

Step 2: Sand and Prep

Before assembling anything, take the time to prep your wood properly.

Sand with 80 grit, move to 120, then finish with 220 for a smooth surface.

What to focus on:

Lightly round over edges for a finished look
Fill any cracks or knots if needed
Wipe all dust off before moving forward

This step is what separates a rough DIY from something that feels polished.

Step 3: Build the Frame

Flip the tabletop over and build your support frame underneath.

The frame should run slightly inset from the edges and land around 109 inches long.

Focus on:

Keeping everything square
Using wood glue + screws for strength
Locking everything in tight so there’s no movement

This is what gives the table long-term durability.

Step 4: Cut and Notch the Legs

Cut your 6×6 Boards into four legs at 30 inches each.

Then mark where each leg will sit on the tabletop corners.

Using a multi-tool and wood chisel, notch out each section so the legs sit clean and flush.

What matters here:

Work slowly and keep edges sharp
Test fit as you go
Keep everything symmetrical

Tip: You may need to start your cut on one side and flip the piece to finish.

Step 5: Install the Legs

Dry fit each leg first to make sure everything lines up.

Once it’s tight, secure them using screws and wood glue.

Focus on:

Keeping legs perfectly flush to the tabletop
Making sure everything sits level
Locking the structure together solidly

This is where the table really starts to feel complete.

Step 6: Stain and Finish

Now for the part that changes everything.

Apply your exterior stain using a stain pad and extension pole for even coverage.

What to focus on:

Use long, even strokes
Avoid pooling or streaking
Let each coat dry fully

Apply 2–3 coats for durability.

This is what protects your table from sun, rain, and everyday wear.

Step 7: Apply Clear Coat

Finish it off with an exterior-rated clear coat.

Lightly sand between coats if needed and apply evenly across the entire surface.

This step helps:

Lock in the color
Add another layer of protection
Extend the life of the table

Step 8: Set It Up and Use It

Move your table into place and start using it.

Add chairs, style it out, and actually enjoy it.

The Final Look

What you end up with is a centerpiece for your backyard. It’s built for hosting, built to last, and honestly just hits different knowing you made it yourself.
