10x15 Refers to the Combined Inner Dimensions of the 2 Roof Openings
When we say a pergola's dimensions are 10x15, we are referring to the combined inside dimensions of the 2 roof openings (from inside-edge to inside-edge). All of the kits featured on this page are meant to have 2 roof openings that are both 10' wide and which combine to be a total of 15' deep. (Note: The combined depth of the 2 roof openings can be divided any way you'd like: both 7.5' deep or one 8' and one 7' deep or one 8.5' and one 6.5' deep or any other combination that adds up to 15 feet.)
The overall outside-edge to outside-edge dimensions of the pergola will be:
- 10' 7.3" wide x 16' 2.6" deep (if you choose a kit for 4x4 posts) OR
- 10' 11.3" wide x 16' 10.6" deep (if you choose a kit for 6x6 posts)
With all of this being said, you can easily change the overall size of your pergola by trimming the wood posts that you plan to use for the roof beams. For example, if you wanted the true outside-edge to outside-edge dimensions of a free-standing pergola to be exactly 10' x 15', you would need to:
- Purchase three 10-foot posts to be the beams running the 10-foot width, and then cut off 7.3 inches (for 4x4 wood posts) or 11.3 inches (for 6x6 wood posts) from each one; and
- Purchase two sets of two posts totaling 15 feet to be the beams running the 15-foot depth, and then cut off a total of 14.6 inches (for 4x4 wood posts) or 22.6 inches (for 6x6 wood posts) per set of two posts.
Reminder: Width & Depth Are Not Always Interchangeable
10' x 15' pergolas are different from 15' x 10' pergolas. The wall-mounted pergolas on this page will attach to your home on the 10' width side and come 15' out from the house wall. For free-standing pergolas with a slatted roof, the roof rafters will be mounted to the 15' beams and run the 10-foot width of the pergola (providing more shade when the afternoon/evening sunlight comes from the 10-foot width side). If your afternoon/evening sunlight will come from the 15-foot side, you'll want a 15x10 pergola instead.
