12 foot Picnic Table Plans

This step by step diy project is about 12 foot picnic picnic table plans plans. I have designed this 12 foot long picnic table so you can enjoy a nice meal in the backyard with the loved ones. This large picnic table features three rows of legs, so it provides plenty of support. Moreover, the picnic table is enough for a large family. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.

When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.

Building-the-legs

The first step of the outdoor project is to build the legs for the 12′ picnic table. As you can easily see in the diagram, you need to make 30 degree cuts to both ends of the 2×6 legs. Smooth the edges with sandpaper.

Tabletop-supports

Next, you need to build the tabletop supports from 2×4 lumber. Make 45 degree cuts to both ends of the supports, following the diagram. Moreover, drill pocket holes into the 2×4 supports, so you can lock it to the tabletop slats.

Building the tabletop

Lay the 2×6 tabletop slats (12′ long) on a level surface. Place 1/4″ plywood pieces between the slats so you can create even gaps. Fit the supports to the slats and then place them equally spaced. Insert 2 1/2″ screws to secure the supports into place tightly.

Decorative cuts

Use a jigsaw to make round decorative cuts to the corners of the tabletop.

Fitting the legs

Fit the 2×6 legs to the picnic table, as shown in the diagram. Clamp the legs to the supports and then drill pilot holes through both components. Insert 3 1/2″ carriage bolts and tighten the components into place. Use two bolts for each joint for a professional result. Using the carriage bolts will also make disassembling the picnic table easy, if you want to move it to another location.

Seat-supports

Build the seat supports from 2×6 lumber. Make 45 degree cuts to both ends of the supports, as shown in the plans. These decorative cuts will add character to the picnic table.

Fitting the seat supports

Align the seat supports to the legs and then clamp them into place tightly. Drill two pilot holes through the braces and through the legs, for each joint. Insert 3 1/2″ carriage bolts to lock the components together tightly. Use a spirit level to plumb the seat supports horizontally.

Seat supports

As you can easily notice in the diagram, you have to install 4 seat supports to the legs of the picnic table.

Seat stretchers

Fit the 2×6 seat stretchers to the picnic table, as shown in the diagram. Drill pocket holes at both ends of the beams and insert 2 1/2″ screws into the supports.

Fitting the seat slats

Fit the 2×6 beams to the sides of the picnic table. Leave about 4″ overhangs on both sides of the seat slats. Drill pilot holes and insert 2 1/2″ screws to lock the slats into place tightly.

Building-the-diagonal-braces

Build the braces for the table from 2×4 lumber. Make 10.3 degrees cut to both ends of the braces. Smooth the edges with sandpaper.

Fitting the diagonal braces

Fit the diagonal braces to the 12 foot picnic table. Center the braces to the supports and drill pocket holes at both ends of the diagonal braces. Insert 2 1/2″ screws to secure the diagonal braces into place tightly.

Last but not least, you need to take care of the finishing touches. Fill the holes with wood putty and let them harden for a few hours. Smooth the surface with 120-220 grit sandpaper and round the exposed edges with a router. Apply a few coats of paint or stain to protect the lumber from the elements and to enhance the look of the 12 foot picnic table.

This picnic table is the ideal project for any garden, as it is easy to build and it the materials don’t cost a fortune. Moreover, if you have a drill, a saw and a sander, you will get the job done in one weekend. As compared to a 6′ or 8′ long picnic table, this 12′ long picnic table is much sturdier, as it features middle legs.
