What You’ll Need
To build an A frame swing, you will need the following materials:
- 4 wood boards – Typically 2×4 or 2×6 lumber is used, in 8 ft lengths
- Wood screws – 3-4″ exterior screws, qty depends on size/number of boards
- Power drill and drill bits
- Saw – Circular saw, jig saw or hand saw
- Sandpaper – Optional, for smoothing cut edges
- Exterior wood stain/sealer – Optional
- Tape measure
- Carpenter’s square
- Swing set brackets and hardware
- Rope, cable or chain – For suspending the swing
- Swing seat or glider
Pressure treated lumber is ideal for outdoor A frame swings, as it will resist rotting and insect damage. Cedar and redwood are other good options. For added longevity, choose galvanized steel swing hangers and hardware.
A Frame Swing Dimensions
Standard dimensions for DIY A frame swings are:
- Height – 6 to 8 feet tall at peak
- Width – 4 to 5 feet wide at base
- Leg angle – Roughly 45 degrees
- Swing height – Adjustable, typically 12″ to 18″ below peak
The exact measurements can vary based on your space and preferences. Taller A frames allow for more swinging area, but require longer boards. Wider bases provide more stability.
How to Build the A Frame
Follow these steps for constructing a basic DIY A frame swing:
- Cut side boards – Cut two boards to the desired height, such as 6 or 8 feet long. These will form the legs.
- Cut crossboards – Cut two boards to the desired width, such as 4 feet long. These will connect the legs.
- Mark leg angles on side boards – Lay the side boards on the ground in parallel, overlapping the ends. Prop one end up at the desired angle, such as 45 degrees. Use a carpenter’s square to mark the angle cut across each board. Allow for a few extra inches to attach the crossboards.
- Cut leg angles – Use a circular saw or handsaw to cut along the angle lines marked on each side board. Smooth any rough edges with sandpaper.
- Assemble A frame – Lay the legs flat on the ground with angle cuts facing up and overlap the ends again. Center the crossboards across the ends, perpendicular to the legs. Attach using several 3-4″ wood screws driven through the crossboards into the legs. Flip over the A frame.
- Attach swing hangers – Position swing hanger brackets evenly spaced along the peak crossboard, aligned with where you want the swing to hang. Follow manufacturer instructions to securely bolt the hangers in place.
- Add swing rope/chain – Run your length of rope, cable or chain through the end holes in the swing hangers. Use clasps or knots to securely connect the ends.
- Hang swing seat – Connect the swing seat or glider to the center of the rope/chain using provided hooks, clamps or rings. Adjust length to get the desired swing height.
- Secure A frame -Anchor the legs with stakes or concrete in the ground to prevent tipping over.
- Apply finish – Paint or stain the A frame swing if desired. Allow proper drying time before use.
Always check that the A frame feels sturdy and swing hardware is tightened properly before use. Periodically inspect for wear or loose fasteners, retightening or replacing as needed.
A Frame Swing Variations
There are many ways to modify the basic A frame swing design:
- Size – Adjust height and width measurements to fit your space or activities. Go taller for more thrill or shorter for younger kids.
- Board size – Use larger 3-4″ thick boards for a chunkier look. Or use multiple 2x boards stacked together for each leg.
- Board quantity – Add side or diagonal bracing between the legs with 1-2 extra boards for a sturdier frame.
- Leg spreaders – Connect the bottoms of the A frame legs with an additional board to spread them farther apart for more stability.
- Swing hangers – Use heavy duty swing hangers rated for adults if older kids or adults will be users.
- Swing type – Replace a regular swing with a porch swing, glider swing, or multi-child swing for more options.
- Roof – Attach a triangular shade roof across the top for shade.
Tips for Building an A Frame Swing
Follow these tips to help your DIY A frame swing project go smoothly and safely:
- Select weather resistant lumber rated for outdoor use.
- Pre-drill holes for screws to prevent splitting boards.
- Use 3-4 screws per crossboard connection for maximum strength.
- Check corners for squareness as you assemble the A frame.
- Make sure swing hangers are installed in the center and spaced evenly.
- Add diagonal bracing between legs for extra stability.
- Anchor legs securely in concrete for permanent installs.
- Consider safety surfacing like mulch or mats under the swing area.
- Supervise children and limit the number of users at one time.
- Inspect hardware and wood periodically for deterioration.
