Square Picnic Table Features

  • Seating on four sides, for a cozier experience
  • Easy to build design 
  • Comfortably seats four adults, could seat as many as 8
  • Smaller footprint may be more suitable for some spaces
  • Fun, modern design 

Sitting around a table, instead of in a line at a table, is usually more desirable.  But most round style picnic tables - whether it's an octagon or a hexagon or a four sided picnic table - become complicated and hard to build.  In this plan, we tried our hardest to create a project that is quick and easy to build, but still gives you a quality project that you will love for many years.

General Instructions

Pre-staining or painting before cutting is recommended.  Use an exterior appropriate finish.

Instructions

Step 1

Screw the 2x6 leg piece to the 2x4 leg piece with four screws, outside edge is flush.  Best face of both boards should be faced inward.

Build four identical.

Step 2

Attach the 2x4 leg side to the shorter, 2x4 apron (36-1/2" long) with two screws per end.  This is important, as it may affect the overall tabletop size. Double check to make sure the overall leg width is 47-1/2" from outside of leg to outside of leg after attaching.

Slightly angling the screws will create more strength in the joint.

Step 3

Repeat with the longer (37-1/2") from the two 2x6 sides of the legs.

Double check that the tabletop dimensions are 47-1/2" x 47-1/2" at the widest part of the legs.

Step 4

Build four of the seat supports by attaching the longer 2x4 to the shorter 2x4s.  

Step 5

TIP: Cut two blocks 13" and use as a spacer to help set the seat supports in the right height.

Attach the seat supports to each of the legs.

Make sure the shorter seat support piece (22") is attached to the 2x6 part of the leg, and the longer (23") seat support piece is attach to the 2x4 side.

Step 6

Cut the 2x4s at a 45 degree angle.  

Set in place and attach first at the top to the underside of the seat support.  Then attach to the legs on the inside with multiple screws.

Step 7

Adjust the table frame for square.

Attach the tabletop boards to the frame with screws.

On the end boards, add extra screws into the aprons and tops of the legs, the end boards are structural.

Step 8

Add the seat boards to the seat supports.

Step 9

Optional seat bracing idea

Finish Used
I used water based penetrating stain in Chocolate from Behr.

Hello Ana White,

How would one go about adjusting the height between the table top and the seat top? By increasing the length of the 45 degree angle seat supports? I want the table to also serve as an outdoor desk the height of the table measuring 29 inches and the height of benches, 20.5 inches. What would the general principle be? Basic geometry I know but it has been a long time...

Many thanks and best regards.

Nice summer project. It turned out great! Easy build. I also added a hole in the center for my patio umbrella. I would recommend using the longer screws.

Nice looking but unsteady. Maybe design issue (2021 build)

I am having issues with the Step 3 method of securing legs. Despite setting screws at an angle. the weight of kids/adult on seats has caused the joint screws to pull out at all four points. The table top is barely secured. I’m concerned wood screw method will continue to fail due to force on seats/legs. What’s your recommend fix?
( Longer screws…?)
I built this table with 2 adirondack chair for our porch.

Frequently Asked Questions

Wood Questions

What kind of wood should I use?
Most of our plans use standard construction lumber like pine or fir. It's affordable, easy to work with, and easy to find. It's also rapidly renewing and biodegradable, so a great eco friendly choice!

Can I use hardwoods instead?
Yes—just keep in mind they're heavier, cost more, and can be tougher on tools and harder to join together and finish. I recommend not tackling a hardwood project until after you have built several softwood projects.

What if my boards are warped?
Choose the straightest boards at the store. You can often work around slight warps by cutting them into shorter pieces.

What wood should I use for outdoor furniture?
Use red-toned or pressure-treated 2x lumber for framing, and cedar or cedar fence pickets for the decking. Outdoor furniture should be built like a deck—your local home center can help recommend the right wood for your climate.

Will my wood move or warp after I build?
Potentially, especially in humid climates. Let your wood acclimate indoors before building. Once acclimated and kept in a stable environment, movement should be minimal. Remember, most houses are built using framing lumber - it's all about keeping moisture down indoors.

Cutting Questions

Do I need a miter saw?
A miter saw is great, creating fast, safe, and precise cuts, even for beginners. But most plans can be built with a circular saw and a straight edge. If using a circular saw to cut, take time to practice, and get good at making cuts, before cutting your project boards.

How do I get clean cuts with a circular saw?
Clamp your board, measure twice, cut slow, and use a sharp blade. This takes practice, so spend some time making cuts. I go through becoming proficient at freehand cutting in my course, it is worth taking if you want to master this skill.

Will the store cut my wood?
Yes—most stores will do rough cuts to help you transport your materials home. But from store to store, the quality of cuts could greatly vary.

Joinery Questions

What screws should I use?
We recommend star-head self tapping screws for framing, most common sizes are 2-1/2", 1-3/4". Pre-drill if close to the edge or you find your wood is splitting.

Do I have to use pocket holes?
Pocket holes are the cheapest, easiest and fastest way to do some joints - like edge to edge or a hidden fastener joint. There are other methods, but these can be time consuming and expensive. We recommend using pocket holes as indicated in plans for best results.

How do I keep things square?
Use a speed square and measure diagonals after each step. Always clamp joints before screwing to keep them tight and flush.

Finishing Questions

Stain or paint before or after building?
A quick sand before and a full finish after gives the best results. Pre-finish if you're doing two-tone or detailed finishes.

What type of finish?
Use oil-based or water-based stain. For paint, cabinet-grade latex or enamel works great. High use surfaces on indoor projects should get a coat of polyurethane, I recommend a Helsman or Spar or other flexible poly that won't crack or peel with wood movement. For exterior projects, use a finish suitable for exterior fences.

How to get a smooth finish?
Start with a well sanded project. Sand between coats (220 grit), wipe clean, and apply light coats with a foam brush or roller.

Plan Questions

Can I change the size?
Many people do, and that's the great thing about building your own furniture! But do keep in mind going bigger might mean more supports are required, and often plans are optimized for minimal material waste.

Are these beginner-friendly?
Yes—plans are written with simple tools and clear steps in mind, with every effort to make plans as simple as possible.

Can I sell what I build?
Absolutely! Just don’t resell or repost the plans themselves.

General Questions

What tools do I really need?
A drill, circular saw, tape measure, square, and a few clamps will get you through most projects.

Do I need a workshop?
Nope! A driveway or small patio is plenty to get started, just make sure you have a level place to work. If you find you are building several projects a year, creating a small workbench is a great way to store tools and have a dedicated workspace.

What if I mess up?
Wood filler, sanding, or flipping boards goes a long way. Mistakes are part of the process!

What can I do to make my projects look more professional?
Start with straight boards, make accurate cuts, clamp all joints, and line up everything neatly. Sand thoroughly, use a neutral finish, and apply it in light coats for a clean look.

I've never built anything before. Where should I start?
Start with a few smaller softwood projects to get hands-on experience. Or if you're tackling a big project, buy a little extra lumber and practice your cuts and joints first. If possible, work with someone who has a bit of experience.

Care & Maintenance

How long will my furniture last?
With good joinery and regular care, your DIY furniture can last for decades. I have pieces in my own home that are over 20 years old and still going strong! One of the best parts about DIY furniture is that it’s easy to repaint, refinish, or repair—so your projects can grow and adapt with you.

How should I care for outdoor furniture?
Lightly pressure wash or hose it down once or twice a year. Tighten screws and reapply finish as needed to protect it—just like a deck or fence. A little upkeep goes a long way in extending the life of your furniture.

How about indoor furniture?
Regularly dust or wipe with a damp cloth. If it starts to look worn, a light sanding and touch-up paint or stain can refresh it in no time. DIY pieces are meant to be durable and fixable—so don’t be afraid to give them some love now and then.
