How to Build a Frame for a Swing


A properly built A-frame for a swing provides stability for any type of swing or hanging recreation equipment. Complete the project in just a few hours to provide a place for hanging a porch swing, a child's swing or other hanging toys. The simple motion of swinging is enjoyable and relaxing for both children and adults. Setting the end posts in concrete ensures a safe, stable swing.

Things You'll Need

  • 4 pieces of 4-by-4 pressure-treated lumber, 12-feet long
  • 1 piece of 4-by-4 pressure-treated lumber, 6-feet long
  • 1 piece of 4-by-6 pressure-treated lumber, 12-feet long
  • Tape measure
  • Pencil
  • Circular saw
  • Clamp
  • Exterior screws
  • Drill with screwdriver bit
  • Concrete mix
  • Shovel
  • 4-foot level
  • Place one 4-by-4 on a sturdy work surface.

  • Use a tape measure to mark a ¼-inch increment on the end of the 4-by-4.

  • Measure 6-inches from the end and make another mark.

  • Measure in 1¾-inches from the mark in Step 3 and make a mark.

  • Draw a line from the mark in the top of the 4-by-4 to the mark near the center of the post on an angle and another line to the center mark from the line on the side of the post.

  • Cut along the lines with a circular saw.

  • Use the cut board as a template to mark and cut the other three 4-by-4 posts.

  • Cut a 6-inch piece of the 4-by-6 beam to use as a spacer. Place two of the cut 4-by-4 posts together with the notches facing each other. Place the spacer in the notches and secure with a clamp so the 4-by-4 posts are on an angle with the tops tight to the spacer and the bottoms spaced farther apart.

  • Measure each 4-by-4 post 6 inches from the bottom of the beam on the inside and mark with a pencil. Lay another 4-by-4 post across the lines. Mark the post along the angled posts with a pencil to create a cut line. Repeat 18 inches further down on the posts.

  • Cut two of each size brace piece. Place each piece into position on each frame section and secure by inserting corrosion-resistant screws with a drill and screwdriver drill bit on an angle through the crosspieces and into the lateral legs.

  • Hold the frame sections vertically and place the 4-by-6 beam into the notches. Secure with exterior screws.

  • Position the frame in the desired location. Mark the locations of the posts with landscaping paint. Move the frame a few feet to the side of the desired location.

  • Dig holes that are 12 inches in diameter and 18-inches deep. Fill with concrete mixed according to package directions in each hole. Place the posts into the holes.

  • Use a 4-foot level to level the top and plumb the sides of the frame.

Tips & Warnings

  • Use a sander to round the corners of the 4-by-4 posts to prevent injuries.
