Measure the space where you want to install your swing. This area will determine how long your porch swing will be. If the ceiling above your porch has joists, exposed beams, or any other structural elements with cracks running between them, you may want to make the bench a length that will allow you to center the anchors for hanging the swing between the cracks.
- Consider how deep the seat and how tall the back will be. Measure the seat and back of a similar chair that you feel comfortable in (e.g. a dining chair). The swing built over the course of these instructions is 20 in. (508 mm) deep in the seat and 18 in. (457 mm) tall in the backrest, which is comfortable for a fairly tall individual but may not be as comfortable for a person with shorter legs.

Choose the materials you will use for building your swing. This article describes building with treated southern yellow pine, but cedar, fir, cypress, juniper, or even birch will work equally well as long as the components are thick and strong enough to support the weight they will carry.
- 3
Gather all the tools, fasteners, and lumber you need for the project. Here is the list broken down by type; see Things You’ll Need for additional dimensions and sizes.
Tools: Circular saw, jigsaw, hammer, tape measure, square, and drill with bits
Fasteners: Wood screws, eye bolts
Lumber: Fifteen 1×4 in. (25.4×102 mm) boards as long as the width of your swing; one 2×6 in (51×152 mm) board that is 8 ft. (2.44 m) long.

Set a table up to work on. A pair of metal sawhorses with a sheet of plywood work great as a makeshift table, but any flat surface that provides a workspace at a comfortable working height will do.
Part 2 of 3: Measuring and Cutting
- 1
Measure and cut seven 2×4 in. (50×100 mm) boards the length you want the finished swing to be. The 2×4 used in this article is 5 ft. (152 cm) long. Cut these boards to length, being careful to make all cuts square (90 degrees).
- 2
Set blocks on the table to support the boards. Next, attach a stop for keeping them from sliding while you rip them to width. If you have a table saw, you can use this for ripping the slats instead.
- 3
Rip the cut boards into slats for the seat and back. The seat slats need to be 3/4 in. (19 mm) wide, while the back slats (which support less weight) only need to be 1/2 in. (12.7mm) wide. For a seat 20 inches (508 mm) deep, you will only need about seat 17 slats (to allow for gaps between slats); for a back 18 inches (457mm) tall, you will only need 15 back slats.
- If your seat or back will be a different size than the one in this example and you aren’t sure how many slats you’ll need, make several slats fewer than the total measurement of the space in inches. Aim on the low side for now; you can always rip more later.
- 4
Drill through each slat, 1 in. (25.4 mm) from both ends, with a 3/16 in. (4.76 mm) drill bit. Later, when you attach the slats to the frame with wood screws, these pre-drilled holes will keep the slats from splitting.
- You may also want to drill a hole in the dead center of each slat depending on whether or not you think your bench needs a center support. If you’re making a short bench and/or working with hardwood, a center support may not be necessary. If in doubt, however, include one. The bench in this tutorial has a center support.
- 5
Cut either four or six 2×6 in. (51x152mm) back and bottom supports. If your bench only needs outer supports, cut two back- and two bottom supports; if it also needs a center support, cut three of each. The length of the back pieces should equal the desired height of the bench; the length of the bottom pieces should equal the desired depth of the seat.
- 6
Draw and cut curves into the back and bottom supports (optional). The bench in this example will have gentle curves cut into the bench supports to make the bench more comfortable, not to mention aesthetically pleasing. The amount of curvature depends on your preference, but the seat and back can actually be straight if you prefer.
- Choose one back support piece, draw the curve freehand with a pencil, then go over it with a marker. Unless the back and bottom supports will be the same length, you will need to do this again with a bottom support piece.
- Cut the marked back support piece with a jigsaw. Leave the narrow end a bit long for trimming to fit the joints together. Next, either trace it onto the other back supports or use it as a jig. Repeat with the bottom support pieces.
- Choose one back support piece, draw the curve freehand with a pencil, then go over it with a marker. Unless the back and bottom supports will be the same length, you will need to do this again with a bottom support piece.
- 7
Cut a miter at the ends of the back and the seat board. This is so the back and seat boards join at the correct angle for the amount of slant (recline) you want your seat to have. You can start by cutting a 45-degree angle into one of the two pieces, then laying it on top of the opposite piece and twisting it until you get the amount of angle you want. When you’re satisfied, mark the angle onto the uncut piece by tracing along the edge of the top piece you just cut, then cut along the traced line. Trace the cut edge of the back support piece into all the other back supports and cut them to match, then do the same with the bottom supports.
- The two angles in all likelihood won’t be the same, but it shouldn’t matter since they are on the bottom rear of the swing, out of sight.
Part 3 of 3: Bringing the Swing Together
- 1
Attach the back supports to the bottom supports. Drill pilot holes for the screws that will join each pair of supports together, then fasten them with 31/2 in. (89 mm), #12 gold-plated wood screws. This is a critical connection: since the screws are the only support for this joint, they will have a good bit of pressure in them.
- Depending on the length of the joint, you might want to insert the two screws at opposing angles.
- 2
Set the completed support-piece pairs on your table and lay the innermost slat of wood you ripped earlier across them. Make sure you’ve spaced the supports evenly and oriented all the back supports in the same direction, then screw the central slat into place.
- Unless you don’t mind cutting into the overhang to accommodate the armrests, don’t situate your slates so that they overhang both side supports. The armrests will later attach to the side supports, meaning the overhang will just get in the way.
- 3
Attach the other slats. First, use a framing square to make sure the support pieces are square with the preliminary slat, then screw on the other slats.
- Place the square along both the preliminary slat and one of the support pieces and measure whether or not they are square. Repeat with the other support pieces as necessary. If necessary, rack the supports (by shifting them sideways) to make a more perfect 90 degree angle.
- Space additional slats across the seat, leaving a 1/4 to 3/8 in (6.35 – 9.5mm) space between them. (If necessary, rip more slats to get the spacing the way you like it.) You can tack these temporarily or go ahead and fasten them securely, but you may find it necessary to adjust them to get your spacing to work out uniformly. Attaching the top-most back slat and front-most seat slat first before filling in the others might make it easier to keep your frame square. Take care to use the thicker (3/4 in.) strips for the seat, and the 1/2 in. (13 mm) strips for the back.
- Place the square along both the preliminary slat and one of the support pieces and measure whether or not they are square. Repeat with the other support pieces as necessary. If necessary, rack the supports (by shifting them sideways) to make a more perfect 90 degree angle.
- 4
Make two armrest supports and armrests. Generally, the armrest should be about 8in (20cm) high and 18-20in (~.5 m) long.
- Make the armrest supports. Cut two wedge-shaped 2×4 in. (50×100 mm) boards about 13 inches (33 cm) long, tapered from 2 3/4 inches (7mm) on one end to 3/4 inch (19mm) on the other.
- Make the actual armrests. Cut two more boards 22in (56cm) long, tapered on one end from 1 1/2 inches (3.8cm) to full width in 10 inches (25.4cm) for each armrest itself.
- Attach the armrests. Locate the height you want the armrest on the back frame, then locate the position you want the support on the seat portion of the frame. Attach these with 3 in. (7.5 cm) #12 wood screws. Fasten through the top of the armrest down into the support board with two more wood screws.
- 5
Drill a hole through the armrest support and the seat frame for the eyebolt.The eyebolt will attach your swing chain to the swing. Then, drill through the back frame for another eyebolt for the back chain. Screw in the eyebolts, place washers over the backs (to keep the nuts from drawing into the wood frame), and tighten the nuts over the ends with a wrench.
- 6
Locate the position and height of your swing. Install eyebolts or eyescrews for the overhead connection, and measure the length you will need your chains to hang your swing. You may find you need to adjust the chains to get the swing tilted back the proper amount to be comfortable for you.
Tips
- Curve any edges that may need it to prevent children from bumping into them and injuring themselves.
- Use galvanized or coated fasteners to prevent corrosion. Galvanized fasteners are not recommended for cedar wood, however.
- Consider making the length of your planks 8 feet when you buy them. Typically, 8 foot lumber is least expensive, and scrap may be used for other projects.
- Sand any edges smooth to prevent splinters or other injuries which may occur from the wood.
- Finish with an exterior coating such as polyurethane or paint to make your swing look better and last longer.
A Testimonial by a porch swing builder
I used my set of porch swing plans to build my mom a beautiful porch swing she absolutely loves. She did not want to buy one already made because they are so expensive! She is right, I don’t blame her, the prices are absolutely outrageous.
My mom wanted a porch swing and she asked me to go look in stores with her. She did not know which model to buy with all the styles out there to choose from. She was thinking about a covered one but after thinking about it, she realised it was not necessary since it was going to be used under the porch.
The store had some nice ones made of metal with thick cushion on it. I remember that we had one of these when we were younger and the metal became all rusty. Besides we could not remove the cushion and soon they got real dirty and damp. So forget about the metal ones.
My mom saw a nice one made of Cedar wood that had cushion that you can remove and take inside. She really liked it but when she saw the price she said; never mind, I will wait. I looked at the price tag, it was almost $1200.00 dollars for that porch swing. I knew she liked it a lot but she did not expect to pay that much.
I noted the model and I found out that I could buy only the cushion if I wanted to. That gave me a good idea. I knew my mom really liked this swing so I went home and pulled out some porch swing plans from my woodwork program. I found the very same model almost immediately. I decided to build her one and offer it to her for mother’s day coming up soon.
I got the list of necessary material and went out to buy the wood. I choose Cedar because it is ideal for a porch swing, it is rot and bug resistant. I also got the necessary hardware and the total on my invoice was $176.00! I also bought the cushions separately for an other $100.00. This was so worth it I was happy to make it that way.
I just set it up in my garage and it took me about 6 hours of slow work to assemble it all together, in my spare time.
On mother’s day I bought the swing at her house while she was out with my sisters pretending I was gonna meet them later and did not say anything. When they got home, she was very surprised when she saw the swing. First she was mad because she taught we all bought it for her. This is way too much money for a gift, she said. But them I told her I made the swing myself and not to worry about it.
She was very happy and so am I because she will be able to enjoy it all summer long!
Using porch swing plans was such a money saver for this project, and I was able to give my mom a gift that I made myself, which made me very proud too. Go ahead and visit my page at http://www.woodworkingplansonline.blogspot.com to find the necessary plans to make porch swings and so much more!
