How to Build a Porch Bench

A porch bench adds just the right amount of comfort and charm. Whether for decoration or casual sitting, the style is up to you. Building a porch bench yourself is not as complicated as you think. With a little bit of know-how and work, you will be relaxing on something made with your own hands. Follow these instructions to build a wooden porch bench.

Tools and Materials

  • Miter Saw
  • Electric drill
  • Level
  • Pencil
  • 7 precut pressure treated 1x6 boards 5 feet in length
  • 2 precut pressure treated 1x6 boards 25 inches long
  • 2 precut pressure treated 2x4 boards 4 feet in length
  • 2 precut pressure treated 2x4 boards 30 inches long
  • 2 precut pressure treated 2x4 boards 24 inches long
  • 2 precut pressure treated 2x4 boards 5 feet in length
  • 1 box 2 ½ inch wood screws

Step 1 – Selecting Lumber

Since your front porch bench will be exposed to the elements, chose pressure treated lumber. Have the lumber precut. This will save you time and worry. Make sure the lumber is not warped and is free of knots.

Step 2 – The Seat Frame

Build a rectangle out of the 2 2x4 boards that are 24 inches long and the 2 2x4 boards that are 5 feet in length. Place the 24-inch boards inside the 5-foot long boards. Your frame should be square. To check this, take diagonal measurements. Those measurements should be the same. Make sure to sink the heads of the screws at each corner.

Step 3 – Attach the Legs

Measure 20 inches on each leg and make a mark. Attach the 2 boards that are 4 feet in length to opposite ends of the frame. Now you can attach the 2 boards that are 30 inches long to the other ends. Make sure the top of the frame is at the 20-inch mark. Lay your level on the frame to make sure it is level.

Step 4 – Making the Seat

Take 4 of the 1x6 boards that are 5 feet in length and screw them to the frame. Lay them side by side. The 4 boards will be 24-inches wide, which is the same dimension of the frame.

Step 5 – The Back

Measure 4 inches up on the long legs from the top of the seat and make a mark. Attach a 1x6 that is 5 feet long above that mark. From that board, measure up 3 inches, make a mark, and attach another 5 foot long 1x6. The last 5 foot long 1x6 goes on top of the 2 longest legs.

Step 6 – The Arms

Cut 45-degree angles on one end of the 25 inch 1x6 boards with the miter saw. Measure 30 inches up on the outside of the long legs and make a mark. The angled ends of the boards attach to the long legs. Screw the other ends to the short legs of the porch bench.

Extra Tip

Use wood filler to cover all screw heads, sand smooth and your wooden porch bench is complete.
