How to Build a Wooden Billboard

Wooden billboards are wooden signs used for advertising. They can be made in various sizes and be built out of various materials. Often homeowners and small business owners will build billboards for different types of sales. A small billboard can be constructed quickly using plywood and construction lumber. To secure the billboard will require digging a small hole and pouring concrete. A wooden billboard like this will be 6 feet high and 3 feet wide.

Tape measure
Level
Treated pine post, 4-by-4-by-96-inches
Treated plywood, 3/4-inch, 36-by-48-inches
Screw gun
6 wood screws, 3-inch
Post hole digger
Hammer
2 landscaping stakes, 20-inch
1 Cubic foot of concrete mix

Instructions

- 1
  Lay the post flat and set the plywood on top of it one of the 48-inch edges is flush with the end of the post. Position the plywood so the 36-inch edges are each 16 ¼ inches away from the sides of the post. Screw the plywood to the post using six screws.
- 2
  Dig a 12-inch-wide, 24-inch-deep hole where you would like to display your billboard. Use your post hole digger. This hole will make the top of your billboard 72 inches above the ground.
- 3
  Set the post with the plywood in the hole and position it so it is perpendicular to the ground using your level. Pound a landscaping stake on two sides of the post so the stakes are at right angles with each other. The stakes should be at a 45-degree angle to the ground and the tops of the stakes should be flush with the ground. They will hold the post in the perpendicular position as the cement cures.

  Pour your cement mix in the hole surrounding the post and let it cure according to instructions. Paint your message on the plywood or nail a sign to the plywood to complete your billboard.
