How to Install a Porch Swing
On this page
Knowing how to install a porch swing comes down to two things. First, screw the hardware into a solid joist or beam that runs across the swing’s hanging points, using eye bolts or swing hangers that carry more than the swing and its riders will ever weigh. Second, set the seat height by the maker’s instructions, which for a traditional swing is typically 17 to 19 inches above the floor. Below we cover how to check your porch, which hardware to buy, the steps in order, and what to do if there is nothing solid overhead.
A hanging swing puts moving, repeated load on a few points in the ceiling, so the joist matters far more than the swing. Most installs that go wrong fail at the ceiling, not at the chain. Take your time on the first half of this guide, and the second half is easy.
Can Your Porch Support a Swing?
Your porch can support a swing if the swing hangs from a load-bearing beam or ceiling joist. POLYWOOD’s hanging guide recommends a beam or joist with support at both ends, and suggests a 2x6 or 2x8, with thicker being better. The finished ceiling surface (beadboard, vinyl, aluminum or drywall) is only a cover and holds nothing.
Find the Joists
Yellow Brick Home calls locating the joists the most important step of the whole job. On a wood or beadboard ceiling, finish nails usually show where the joists sit. On thin vinyl or aluminum ceilings, a stud finder with a deep scan mode can help. Joists often run from the house toward the front of the porch, but Yellow Brick Home points out that this is never guaranteed, so confirm it before you buy a kit. Their test: drill one tiny exploratory hole with your smallest bit. If it misses wood, fill it with wood putty and dab on a little stain.
Check the Direction and the Spacing
The direction the joists run decides which hangers you can use, because the two top mounting points need to land on wood. Mark both spots with masking tape before you drill. POLYWOOD says the mounting hardware should sit 4 to 6 inches wider than the swing’s length, measured arm to arm, and that you should leave 3 to 4 feet in front and behind the swing and 12 to 14 inches on each side. Yellow Brick Home found the 2.5 to 3 feet of back clearance often quoted online was more than they needed and settled on about 20 inches. Use the maker’s numbers first, and only tighten them if the swing still clears the wall when you push it hard.
When to Call a Pro
Bring in a carpenter if you cannot find a joist, if the wood looks soft or rotted, if the porch roof is old or sagging, or if you are hanging a heavy daybed-style swing. POLYWOOD calls its daybed swing an advanced project and recommends professional installation. The same goes for any ceiling you cannot open up to see what is behind it.
Hardware You Need
For a traditional porch swing, you need four things: two top mounts (eye bolts, hooks or swing hangers), chain or rope, quick links or connectors, and the swing itself. POLYWOOD notes that exact hardware depends on your structure and suggests asking a carpenter or hardware professional. Whatever you pick, check its load rating against the swing and the people who will sit on it. POLYWOOD cites an average porch swing capacity of about 550 pounds, but says it varies with size, material and hardware, so read your own manual.
Eye Bolts, Hooks and Swing Hangers
Swing hangers come in horizontal and vertical styles. Yellow Brick Home used vertical hangers for their compact shape and fastened them with the included lag bolts, driving them with a socket adapter on an impact drill. Eye bolts that screw straight through a joist and are held by a nut and washer on the far side are another common route, if you can reach the top of the joist. Choose galvanized or stainless steel for a porch that sees weather. POLYWOOD recommends galvanized steel hardware for a stronger setup.
Chain, Rope and Connectors
Many swings ship with a chain kit. POLYWOOD’s traditional swings, for example, include a galvanized steel chain kit with four 5-foot chain sections, four eye bolts and six quick link connectors. Quick links close with a threaded sleeve, so make sure each one is fully closed before you sit down.
A Suspension Kit Instead of Loose Parts
Step by Step
The order below suits a standard four-point swing hung from two overhead mounts. Read your swing’s manual first. If it differs from the steps here, the manual wins.
Before You Start
Gather a stud finder, a pencil, masking tape, a tape measure, a power drill with a bit that matches the pilot hole in your hardware instructions, a socket wrench, a level, and a stepladder. Ask someone to help for the hanging step, because holding a swing level while you connect it is a two-person job. POLYWOOD’s daybed instructions call for 3/16-inch pilot holes with their lag bolts, but your hardware may need a different size, so follow the instructions that came with it.
Install the Hardware
- Measure. Measure the swing from arm to arm and add 4 to 6 inches, per POLYWOOD’s guidance, to find the spacing between your two top mounts.
- Mark. Find the joist, then mark both mounting points with masking tape. Use a level to keep the two marks square to the swing’s line.
- Drill. Drill pilot holes at each mark to the size your hardware calls for.
- Install. Fasten each hanger or eye bolt into the joist, tightening until it is firm and does not rotate.
Hang and Level the Swing
- Attach the chains. Following POLYWOOD’s traditional swing steps, thread a chain through the armrest hole, secure it with a quick link to the eye bolt below, and attach the other end to the eye bolt at the back of the armrest. Repeat on the other side. Then attach a remaining chain section to the center link of each chain so the two form an upside-down Y.
- Hang it. Measure the chain length for the height you want. With a helper holding the swing, connect the remaining quick links to the mounting hardware.
- Level it. Make sure the chains match in length on both sides. To adjust the pitch, POLYWOOD says to move the middle fasteners one or two links, keeping them identical on both sides.
- Test it. Confirm every connection is secure and every quick link is fully closed. Add weight gradually, push the swing and tug on the chains. If it wobbles, sits unevenly or shifts, stop and recheck.
How High Should a Porch Swing Be?
A traditional porch swing seat should hang about 17 to 19 inches above the floor, according to POLYWOOD. That is roughly the height of a dining chair, so your feet reach the floor and the swing can still move freely. POLYWOOD lists a different figure for daybed-style swings, which hang 10 to 12 inches off the floor, so check which type you own.
Adjusting for Your Family
The 17 to 19 inch range is a starting point. Yellow Brick Home hung their swing lower, at about 15 inches including the cushion, to suit shorter people in the family. POLYWOOD’s FAQ gives a wider range of 18 to 24 inches for taller users. Measure from the floor to the top of the seat with the cushion in place, and remember that chains and ropes can settle a little after the first few weeks of use.
Do Not Hang It From a Tree
POLYWOOD advises against using a tree for a porch swing. Bark can grow over chains, and rope or chain rubbing can wear the bark away, which weakens the wood and invites insects and fungi. A porch beam or a pergola with proper posts is the better choice. Our guide to the best patio swings covers options for a yard.
Chains vs Rope
Most swings can use either. The choice is mostly about look, noise and how much adjusting you want to do. POLYWOOD’s guide compares them as below.
Hanging a Porch Swing With Chains
Chain is durable, weather resistant and easy to level, because you can shorten one side by a link at a time. POLYWOOD notes it can be noisy and uncomfortable to handle if it is not properly coated. If you hang with chain, check each quick link or S hook is fully closed, and match the chain length left and right before you load the swing.
Hanging a Porch Swing With Rope
Rope gives a softer look and, per POLYWOOD, a bit more elasticity for a smoother swing. Synthetic rope is durable and weather resistant, while natural fiber needs regular care and is more prone to damage. Yellow Brick Home used tan nylon rope, tied through the eye bolts in the swing base, and added a heavy-duty zip tie to stop the rope from shifting front to back. Rope needs a rope-rated hanger, and you should inspect it for fraying a few times a year.
No Joists? Options
If you cannot find a joist where you want the swing, you have three realistic options: add a beam, hang from a different structure, or buy a swing with a stand. All three are better than screwing into ceiling board.
Add a Beam or Use Another Structure
A carpenter can bolt a new beam across existing rafters or posts and hang the swing from that. POLYWOOD mentions a patio pergola as another structure that can work, as long as the beams are load bearing and supported at both ends. If your pergola is a kit, check its manual for a hanging load rating, and see our hanging egg chairs guide for stand-based options that avoid ceiling mounting entirely.
Use a Swing With a Stand
POLYWOOD’s guide suggests that if you have no overhead support, a porch swing set with a stand is the answer. The frame carries the load, so nothing goes into your roof or ceiling, and you can move it later. The trade-off is floor space: a stand needs more room around it than a hanging swing.
