Design and preparation of the outdoor wooden bench

Before you begin, it's important to define the bench's dimensions. For this project, we'll build a standard bench measuring 120 cm long, 48 cm wide, and 50 cm high with a 60 cm backrest, similar to the one pictured. The wooden bench in the picture only has four legs.
If you're considering making it longer, I personally suggest reinforcing the lower part of the seat with crossbars to give greater strength to the central part and prevent the seat from sagging over time.
Outdoor Wooden Bench Plans and Components
I include a detailed diagram of the following parts:
- Seat: 4 boards thickness 40 mm x width 120 mm, length 120 cm.
- Back: 2 or 3 boards of thickness 40 mm x width 120 mm, length 120 cm.
- Dimensions: thickness 40 mm x width 120 mm, length 150 cm.
- Pressure-treated green pine wood. It appears greenish at first, but fades after a few weeks.
- Sharp, brushed edges with beveled edges. Long-lasting durability. Weather-resistant.

Building a Wooden Bench Step by Step
1. Cut the wood
If you don't choose to purchase pre-cut lumber as suggested above, use a circular saw to cut the boards to the measurements indicated. Make sure the cuts are precise to ensure a solid assembly.
2. Sand all parts
Sand wood surfaces to remove splinters and achieve a smooth finish. Start with medium-grit sandpaper and finish with fine-grit sandpaper.
3. Assemble the legs
- Join two side boards to each leg with dowels and wood glue.
- Use a set square to make sure the angles are right.
4. Fix the side reinforcements
Dowel the reinforcing bars to the legs, creating a stable frame. This will provide additional support for the bench.
5. Place the seat
- Center the seat board over the frame and secure with dowels from the bottom.
- If you prefer a cleaner finish, use hidden screws or special hardware.
6. Protection and finishing
- Apply a coat of wood protector or varnish to prolong the life of the bench.
- If you want to personalize it, paint it with bright colors or use an antiquing technique.
