A basketball backboard can be built by cutting a rectangle from plywood, painting the aim point and trim and attaching it to an elevated surface or structure. People tend to anchor the backboard on the exterior of a house or other structure to provide the best stability.
Step 1: Gather materials
Begin with a piece of plywood at least 3 feet by 4 feet to serve as the backboard. A paintbrush and paint are also required. White and red paint are standard. As for tools, obtain a drill, four heavy-duty screws, and a table or hand saw.
Step 2: Cut the backboardDraw a rectangle with the proper backboard dimensions, 3 feet by 4 feet, on the plywood, and use the saw to cut it out. If the plywood is already 3 feet by 4 feet, this step can be skipped.
Step 3: Paint the backboardPaint the entire backboard white. It may take more than one coat to get good color saturation, as the plywood may absorb some of the paint. When this dries, paint a 12-inch by 12-inch red square outline centered at the bottom of the backboard. This is the aim point. With red, paint the trim of the backboard. Let the paint dry completely.
Step 4: Attach the backboardDrill four evenly spaced holes into each of the backboard's corners and into the wall where the backboard will go. Use the screws to secure the backboard to the surface.
