Step 1. Plan Your Space
Choose the location and get an idea for the amount of space you would like to use for your pergola.
Determine Rafter Length (Attached Pergola)
The length of rafters (also referred to as “Depth”), will be calculated by measuring the distance you would like to have from the wall to the outside of the posts (for attached), plus the overhang.
Determine Rafter Length (Freestanding Pergola)
For a freestanding pergola, the difference is that the Rafter is not attached to a wall, so there is overhang on both sides. The length of rafters (also referred to as “Depth”), will be calculated by measuring the distance you would like to have between the outside of the posts, plus the overhang.
Step 3: Determine Beam Length
The length of beams (also referred to as “Width”), will be calculated by measuring your desired outside post to post width plus the overhang. Using a tape measure, pull your second measurement between the points where you’d like the outside edges of each post to land. This is Measurement B. Then, add the overhang on each end to that measurement.
Step 5. Determine Post Height
Once you’ve decided on the size pergola you’re ordering, you’ll choose the height of your posts. We offer posts with standard lengths of 8 feet, 10 feet and 12 feet, and can customize post lengths upon request. When trying to decide the length of pergola posts needed for your wood pergola kit, there are a few things to consider.
