    Make a Back Yard Pergola

    Another option for adding more shade would be to use twice as many 2 x 2's (or more) on top instead of 2 x 4's. I have build wood pergolas with 1 1/2" space between the 2 x 2's (actual dimension of treated 2 x 2 is 1 1/2"). This provides a minimum of 50% shade if the sun is DIRECTLY overhead. At even a slight angle, the shadows "link" together to give total shade without reducing the ambient light. This also protects patio furniture from excessive UV damage from the sun. You can purchase the treated 2 x 2's from any lumber store as deck spindles for handrails. They have pre-cut spindles (36" to 42") but for a pergola, you would want to buy them in 10' or 12' lengths. For upstate NY, your design is perfect, especially with vines growing over the top. ...see more »Another option for adding more shade would be to use twice as many 2 x 2's (or more) on top instead of 2 x 4's.

    Take a look at the post I just made. I have used the 2 x 2 design in Vegas - works great. This picture is an aluminum pergola but you get the idea of shade you can have by using more 2 x 2's when building one is southern states.

    Lol. I agree. A Pergola is more about decoration and functionality.
