General Instructions

Work on a clean level surface. Check for square after each step. Get some help on this project, it will be difficult to work alone. Recommended to paint and stain your boards before building to ensure all edges are sealed, then touch up paint after finishing. Use necessary safety precautions and equipment. Predrill and countersink you screws or drill holes for bolts and tighten with a washer and nut. Remember, you can click photos for a larger view.

Step 1

How to Build an Adult Picnic Table

1. Tabletop. Measure 2″ and 29 1/4″ from the outsides of all the tabletop boards and make a mark. Cut your supports board ends at a 45 degree angle on the ends as shown above. Then attach the tabletop boards to the supports through the tops using 2 1/2″ screws and glue. Start on the outsides and work inward, keeping an even 1/2″ gap between the boards. Use the marks you made to guide you in placing the support boards in line with the tabletop boards.

Step 2

2. Legs. Okay, now it gets just a little tricky. Start by cutting your legs at 30 degree angles on both ends, so the ends are parallel. Then line up the legs with the inner edge of the boards between the middle and outside boards. Use 2 1/2″ screws and glue to fasten to the inside of the table support as shown above.

Step 3

3. Seat Supports. Take your square and measure at a 90 degree angle from the underside of the table up 12″ and make a mark on the legs. Cut your seat supports at 45 degree angles on the ends. Then from the long point, measure 11 1/2″ in from the outer point and make a mark. Line this mark up with the edge of the legs, keeping the top of the seat support (shown as the bottom because the table is upside down) level with the marks made on the legs. Fasten with 2 1/2″ screws and glue.

Step 4

4. Cross Supports. Last tricky step. First, take a square of the table by measuring from the outer points of the legs to the diagonal opposite leg. Do this for both diagonals. Push the opposite legs together on the longer diagonal until your diagonals match up in distance. Then cut your cross supports at 25 degrees off square on both ends, ends are parallel. Fasten in place using 2 1/2″ screws and glue, centered on the supports as shown above. For one of the cross supports, you will need to screw at an angle from the side of the cross support in the tabletop support.

Step 5

How to Build an Adult Picnic Table

5. Seats. Start on the outsides of the seats and screw down the outer seat boards using 2 1/2″ screws. The overhang on the ends is 2″. Then leave a 1/2″ gap and fasten the inside seat board.

Ana, I seriously think you

Ana, I seriously think you are a mind reader! I have been hopefully waiting for these plans & you made them happen girly! I love your blog. My hubby and I are really young parents just trying to make our new house a home and of course I have champagne taste on a cheap beer budget! but thanks to you I can actually decorate the way I want to and not have to resort to cheap big box furniture. Thank you, thank you, thank you! ;)

I would have made one when my children where little if the mini picnic tables had been around. I never saw them in wood, just classic plastic.

I love all the colors.

I am so glad I found this

I am so glad I found this site. And this might get old, but you really are an inspiration! My husband (who can't hang a picture) is not convinced yet that this is a worthy endeavor but I aim to prove him wrong.

Just got wood yesterday for the bigger kids picnic table. I bought nails that you would use for a composite deck cause I'm scared of rust. Were these the right choice?

Also, I'm such a beginner, I would love to see more tutorials like how to use a "square" and simple things like that or did I miss this somewhere? I bought the jigsaw/ sander too so I'm hoping I can use those for angle cuts??!!

After seeing so many other people's work, the chant in my head says, "I can do it" but I'm soooo scared. Guess just gotta jump in!!

Is everyone using oil based paint to paint these? My husband and I are having a disagreement on how to paint ours :)

Sweet!!! I planned on making the kid size, then you came out with the big kid size, and I thought, OHHH, let's build that one. But now, I am going with the full size that way the whole family can fit for a picnic!!! You are so wonderful!

We found a saw at a garage

We found a saw at a garage sale this morning...is it impossible to make these things without a nail gun. Just to use finishing nails and a hammer? I am really excited to do these projects but can't stomach buying more tools on a students budget...

I stumbled on this blog a few

I stumbled on this blog a few weeks ago and decided to build this as my first DIY project since my child surely would not criticize something so super cool? She loved it!! It was so easy (after I figured out how to use the saw that is). Anyway, I am raising money for my 2 day walk for breast cancer in late October and have decided to make some of these to sell for my team to raise funds...I mean who would not LOVE a pink picnic table for a cause? Thanks so much for making these available...making a bed next since my 4 year old saw the farmhouse bad and " can not live without it."

I'm thrilled to find these

I'm thrilled to find these plans for an adult-size table. Because we don't have a deck and our table will be on the grass, I prefer a traditional picnic table rather than a table and chairs. I was appalled to find that our home-improvement store did not carry plans for such a basic project. Pre-made ones I found were priced in the hundreds for what I estimate is about $50 worth of materials. This will be my first summer building project.

I just finished the full-size

I just finished the full-size picnic table today, and I absolutely love it. It looks so natural in our mountain setting. I blogged about the process here on my blog, The Handy Hausfrau.

A quick tip: measure and draw the 30 degree angles on the legs and the 25 degree angles on the center supports before you cut the boards. If you cut the pieces to 33" and 28.5" respectivly before you mark the angles, you won't have enough board to make two parallel cuts.

Thanks for the plans, Ana, and keep up the great work. I can't wait to build another one of your projects.

Ana, Thanks so much for


Thanks so much for these plans! My hubby and I just moved into a new home and the owner of the house had a picnic table and when we asked about it he said he was going to keep it. We didn't let that stop us! I had been "lurking" on your site for a while and had bookmarked many of the plans you have, so I printed out these and my hubby built us a great plum table. Oh, and we used Sara's tip re: measuring the angles before cutting. We've gotten lots of compliments and some even asked if he built this from a kit because it was so sturdy and great!

After finishing ours, he built a toddler one in pink and purple for our friend's daughter. Her table was supposed to go outside, but the little one loved it so much she asked to keep it inside because she didn't want it to get dirty.

Next up, the storage daybed, shelves and, my absolute fave, the farmhouse table from Restoration Hardware! Thanks again for all these great plans!

I want to extend this tables

I want to extend this tables length by about two feet. Has anyone done this? Will I need to add extra support (third leg in the middle)?


posted by sara (not verified) | on Mon, 2011-01-24 15:18


I CANNOT wait to get started on these! Can somebody tell me how many this plan seats comfortably? Maybe, I'll just make 2. We have a large family, and we are hoping to expand it still. ;o) I am new to the site and so excited about all these fun ideas for our home. Thanks Jay

How much overhang is okay?

I am making this table for our dining area. It will be a 10 ft table, so I plan to basically double the table, only using 10' long boards on the top and seats. For the middle supports, I plan to join the two supports together. I am also going to use all 2x6s instead of 2x4 for the support. I may use 2x12 for the top and seats, depending on the price. If I extend the overhang to be a foot from the end supports so there is plenty of leg room for sitting at the ends, will the table still be stable?

how many adults will this

how many adults will this picnic table sit comfortably? Thank you

12 inches down?

I'm so confused. I started this project and, like all my work, I have to shim something because I measure like a fool.
I totally get the 11.5" on either side of the seat supports, but if I am also trying to measure them down 12" that math doesn't work out. Which is more important? Help!

I'd like to include an umbrella hole in the middle of this picnic table. Any thoughts on how to best do this? If I include 4 board supports and thus separate the center supports by 2-3 inches, what angle will I have to cut the leg cross braces? Thoughts?
