Picnic Table With Detached Benches




Entertain thoughts of backyard barbecues and cookouts, having the neighbors over and eating outside with the family? A solid picnic table can be a central part of all of those events, and it doesn't have to be expensive or intricate. This design costs around $100 to build and just 4-6 hours of your time.

Step 1: Table Dimensions and Design

This particular table is very sturdy and probably a bit overbuilt. The benches can easily acommodate four adults, and if one person sits on the end, it won't tip the bench (within reason).

For the purposes of this instructable, the directions given will work if you use a different size or length table due to the absence of exact dimensions. For the curious, here are the approximate cut lengths for each member as this table was built:

Top: (5) 2x6's
Legs: (4) 2x4 , ~38"
Leg cradle: (2) 2x4, ~29"
Center bracket: (1) 2x4, ~29"
Leg brace: (2) 2x4, ~38"

Two Benches
Top: (8) 2x4's
Legs: (12) 2x4, ~23"
Leg cradle: (6) 2x4, ~15"
Leg brace: (4) 2x4, ~13"
Leg brace support: (4) 2x4, ~15"

Table legs were inset 18"
Bench outer legs were inset 12"

- The benches are very wide and comfortable. A more standard bench would probably use only three 2x4's for the top. You could also use 2x6's if you wish.

- The table itself at 30" across may be narrow if you plan on having a lot of guests and food all at the table at once. You may want to consider using an additional 2x6 for a 36" width. As we typically have less than 8 total at the table, food is located at the table ends and the table settings are in the center.

Step 2: Gather Tools and Materials

Exact bill of materials depends on desired table dimensions.
This is based on 30"x30"x96" table and two 16"x20"x96" benches

(17) 2x4 #2 pine ~2.70 ea
(5) 2x6 #2 pine ~3.95 ea
(2) 1lb box 2.5" deck screws ~8.00 ea
(1) 1qt deck stain/sealant ~11.40
(2) 3pk foam brushes ~0.99 ea
(1) 14"x3.5"x1/2" 'scrap' hardwood board (for spacers)

The quality of the dimensional lumber is going to vary quite a bit even on the same pallete. Take your time and pick the best looking pieces, it will save you time and hassle later. Avoid curl, checks and rough edges. For this build, we had decent luck with the selection but eventually returned to replace two of the five 2x6's.

Sandpaper or Belt sander
Clamps (a few, up to 30" length)
Sawhorses, or a level piece of ground

Tool cost is not included in the estimate - if you don't have power tools of your own or to borrow, you'll be off on the time estimate. Alternatively, you can buy the tools you don't have, but you will be off on the cost estimate.

Step 3: Lay It All Out

Start by choosing your best 2x4's and lay them on the sawhorses face down. Position the sawhorses at the same place you would like to place the bench legs.

Cut any 1/4" plywood or board to use as spacer material - we're not going to leave the spacers in, so you can use the ones that are meant for the table top.

Next, add the spacers and clamp the whole bench top together at both ends.

Step 4: Create the Legs

Now it is time to make the legs for your benches.

On the bench surface, mark, square and clamp two sections of 2x4 to create a 'leg angle jig'. This is much easier than using math and calculating angles!

Place the first leg to be marked over the jig so that it crosses each jig 2x4 about a half an inch inside the bench top. Carefully mark the underside with a pencil in at least two places, and use a straight edge to complete the line. Err on the long side when you make your cut.

Refine the first leg until it fits neatly inside the jig, then clone it! In our case, we had 6 sets of legs, or 12 identical leg pieces.

Assemble the legs in the jig.

Step 5: Create the Leg Cradle

-Take a set of finished legs and stand it up on the bench
-Set a 2x4" next to it and mark it's length with a pencil
-Mark the locations of where the leg intercepts the 2x4" carefully
-Err on the side of removing more material when cutting the leg cradle

The finished piece will be about 1/2" shorter than the width of the bench, just like the legs.

Optionally, you can cut an angle off the outside edge.

Step 6: Attach Legs to Benches

Position the leg cradles on the benches - we places ours only 12" from the ends to make the bench less 'tippable' if one person sat alone on the end of the bench. Because this is a 96" piece, we opted to use a third set of legs in the middle of the bench.

Make sure to predrill the holes to avoid splitting the wood, especially where the lag cradle attaches to the leg.

Step 7: Lay Out the Table Top

This is exactly the same process as the benches, except we wanted to keep the spacers because it was a nice scrap of redwood we had. So we tacked the spacers into the sides of the boards using 1" brads.

Follow the same steps from the benches to assemble the legs and cradles.

Step 8: Add Leg Bracing

The bracing is done differently on the benches and the table.

On the benches, the outside legs have a single brace that runs a 45 degree angle, supported by an additional crosspiece that connects to all the pieces of the top bench.

On the table, we wanted to have a single meeting point for the braces, so a single support was places at the midpoint between the legs and the angles were individually marked and cut to get the best fit. In theory, it should be close to a 30/60 degree angle for the cuts, but it is best to mark and measure.

Step 9: Wrapping It Up

Once the table is assembled, you have the choice of how to finish the table. The #2 lumber can be rough in patches and it may or may not be worth it to you to spend a lot of time sanding or planing.

Another option is to use a round router bit around the edges of the table and benches to add to comfort.

Now you have your own sturdy solid picnic table! Enjoy.

One thing that might help in building the bench legs. The boards that you clamp in place should be thicker than the actual leg boards. That way when you set the second leg board on top of the first leg you have something to reference it to. Easiest way would be to just put a piece of plywood under the reference boards before you clamp them in place. Hope this makes sense and helps.

Awesome design I've got some marine hardwood (iroko I think). Can't wait to make my own!

I made one of these tables on a Saturday with some friends. I love how I could fudge the dimensions a little bit here and there. I built with another gentlemen who 6 foot 4+ man like me and we got done and were proud of it and thought it was a perfect then my lady came out and gave me a funny look cause we made it rather taller then we probably should but meh its great for me hahaha!! Thanks for putting this up, i was thrilled to get the plans and sense of direction to go with!

Thanks for the instructable!

A friend and I started this little project this weekend using your design as a starting point. I liked the idea of detached benches, and your "measure twice, cut the first time, measure again, then make the final cut" way of building things.

I had to tear up a frame from who knows what off a slab in my back yard, and to my surprise found several good treated 2x4's that were perfect for this. I had enough to make the two benches, but I'll have to find another weekend to go to the Depot and get lumber for the table.

The first bench took about 2hrs, but the second one was done in less than an hour.

I found it helped to make a template for the legs out of cardboard the night before... although, the last leg attached was a little short (measure twice, cut the first time...) it was easily fixed with a little shimmy.

I also opted to only use two sets of legs on ea. bench instead of three (my benches are 6' x 1') and they feel quite sturdy.

Now I have two sturdy benches for the price of 50-75 wood screws!

This is the only thing that's confusing me. Are these pieces cut to any specific specifications?

The way I have written this, it may be adapted to any table size. The key is the choice of table and bench width - once you have the top width determined, all sizing is based on that. For example, take a look at the picture in step 4. Two guide 2x4's are clamped about 18 inches apart (the legs will be 18" tall). By placing the 2x4 to be cut on top, you can trace out the exact cut angle using the guide 2x4's. So all you need to measure is the height, which is equal or less than the width you selected.

This is a great instructable.  When I made mine, it was very similar but my wood for the bench and table tops was not flat.  I ran it through a planer and evened out the thickness as well as reduced nearly all of the warping and twisting.  I also used bolts instead of screws for most of the joining, but only because I had them left over from a previous project.

Marine varnish is a good choice for a protective finish.

Great job!

Me and my dad are making this picnic table and bench the only thing we did different was subtract a 2x4 from each beach then added an extra 2x6 to the table .it looks great so far . However yesterday when we were almost finishing up we got stuck on how to get the angles for the table Braces can you please explain how you got them.My dad said he was going to get some raft roofing book but that sounds too complicated and all of the instructions you've given up to this point have been pretty simple so it cant be that hard .

The leg braces, as in step 8?

Do you have a power saw? If not, my method is probable too labor intensive to be practical.

We used a highly unscientific method, measure twice, cut the first time, measure again and then make the final cut (repeat as necessary. Since the legs were already attached to the table, we held the piece to-be-cut up to the legs and eyeballed it. It takes some finesse, but after a few you'll get the hang of it.

If you want to calculate it, it's also pretty easy to get a rough estimate. If the brace were there, it creates a triangle. Measure the sides of the triagle; the length of the board will be approximately equal to the hypotenusehttp://en.wikipedia.org/wiki/Hypotenuse , within the width of the board (cut it long!).

Good luck =)

Thanks for replying , we figured it out . Yes we have a power saw ,I couldn't imagine sawing 48 pieces manually that would've been hell lol I posted a picture of the final product thanks so much for posting the instructions .


I didn't make the whole table, as here in Sicily lumber is very expensive. I just made a 1.5ft bench for sitting. When I get back to the states I'll have to make another bench. Here lumber for the dimensions you had would cost me somewhere near 100 euro ($125 +/-). I also don't have all the fancy tools you have (yet!) so I had to improvise on a few things. Like the leg braces. I didn't have the lumber to make them so I used a crude method. But all in all it's not bad for my first attempt at something like this. Also, how would you recommend leveling out the legs if they aren't quite level? My bench is fairly stable, but it does wobbles if you move just right.

I'd look into shimming the legs, as opposed to re-cutting. Maybe you can add some pieces of rubber, like old bike tires, and tack them to the bottom of the legs?

Looks very tidy, and sturdy. Are you going to treat the timber in any way, it looks untreated? L

It is almost fully stained with a light cedar colored stain - I need to run to the store to get a little more, I did two coats on the top. That will be followed by a clear polyurethane coat as well.
