How Do You Build a Tennis Backboard?
To build a tennis backboard, build a support frame out of wooden beams. Then, attach sheets of plywood. Install metal fence brackets to the back of the support frame, and hang it on a fence.
Build the backboard
Use large sheets of plywood to build a backboard that measures 16 feet tall by 16 feet wide. Anchor the sheets together using screws and slim wood braces. Paint it a solid color. Add a straight white stripe at the net height, and set the board aside to dry.
Build backboard supports
Buy five 12-foot wooden beams that measure 4 inches square. Choose beams that are made from pressure-treated wood to prevent the backboard from warping. Lay the beams out at 4-foot intervals. Lay 2-inch-by-4-inch beams vertically across the boards to form a grid, placing one beam every 2 feet. Screw the pieces together.
Attach the backboard
Flip the backboard over so that it is laying on the support frame, making sure the painted side is facing up. Screw it into the 2-foot-by-4-foot beams.
Add metal brackets
Buy 16 metal fence brackets. Flip the backboard assembly over. Attach one bracket every 4 feet along the top edge of the support frame. Do the same in four vertical lines, attaching one after every 4 feet.
Hang the backboard
Use the metal brackets to secure the backboard assembly to a tall fence. Ensure that the side with the net line is closest to the ground.
