Large 16' Picnic Table Plans | HowToSpecialist - How to Build, Step by Step DIY Plans

This step by step woodworking project is about 16′ picnic table plans. I have designed this extra large picnic table, so you can really gather with the family and friends. You always have the alternative of building a couple of 8′ or 10′ long picnic tables, but this project is unique and it will stand out. You can build this picnic table in one weekend. See my other DIY projects HERE.

We recommend you to invest in the best materials you could afford. Therefore, you should buy weather-resistant lumber, such as pine or cedar. Always take accurate measurements before adjusting the size of the components at the proper size. Drill pilot holes trough the components before inserting the wood screws, to prevent the wood from splitting. See all my Premium Plans HERE.

How to build a picnic table

Building the legs

Start the woodworking project by framing the legs for the 16 foot picnic table. Make 30 degree cuts to both ends of the legs, as shown in the diagram. Smooth the edges with sandpaper for a professional result.

Building the sides

Use 2×4 lumber for the top support and 2×6 lumber for the seat supports. As you can easily notice in the diagram, you need to make decorative cuts to both ends of the beams. Clamp the supports to the legs, after aligning them together tightly. Drill pilot holes through the supports and through the legs. Then lock them together by inserting 3 1/2″ carriage bolts. Use two carriage bolts for each joint.

Pocket holes

Drill pocket holes through the tabletop supports. Drill two pocket holes for each slat.

Fitting the tabletop slats

Lay the 2×6 tabletop slats on a level surface and then fit pieces of 1/4″ plywood between them, to create even gaps. Align the edges flush and make sure you insert 2 1/2″ screws through the supports. Plumb the legs with a spirit level and make sure the corners are square.

Fitting the seat supports

Fit 2×6 stretchers to the sides of the picnic table. Cut the stretchers at the right dimensions and then drill pocket holes at both ends of the beams. Fit the stretchers into place and then insert 2 1/2″ screws to lock them into place tightly.

Fitting the seat slats

Fit the 2×6 slats to the seats of the picnic table. Align the edges and make sure you fit a piece of 1/4″ plywood between the slats. Leave 4″ overhangs on both sides of the seats. Drill pilot holes through the slats and insert 2 1/2″ screws into the frame.

Building the diagonal braces

In order to make the picnic table really rigid, I recommend you to fit diagonal braces. Make 7.6 degree cuts to both ends of the 2×4 braces.

Fitting the diagonal braces

Center the braces into place and then lock them into place with 2 1/2″ screws. Align everything with attention and drill pilot holes to prevent the wood from splitting.

16 foot Picnic Table

This is a very long picnic table, so you should really think about whether you’re better off building two 8′ picnic tables. This bench is roomy and really sturdy, but it will get quite heavy and hard to move from one location to another.

This 16 foot picnic table is super easy to build and it will add value to your garden. This table with benches would go perfectly near a bbq. Fill the holes with wood putty and smooth the surface with 120-220 grit sandpaper. Apply a few coats of paint or stain to enhance the look of the picnic table.If you like my project, don’t forget to SHARE it on Facebook and Pinterest.
