Everything you love about the classic picnic table, but in a cozier, updated design!

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.


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.

Finishing Instructions
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.
