Pergola Layout
The layout of your pergola and support posts is important. You will need to consider post
locations and the slope of concrete patios and wood decks. Before digging, check for underground
utilities. The North America One Call Referral Service at 1.888.258.0808 connects you to a national
directory of utility companies.
The support posts are positioned 28" inside the tips of the top beams. To accommodate smaller
outdoor living areas the positioning of the posts may be moved inward, make sure the center of
the post is positioned in the center of the notched beams.
Finding the correct placement of your columns and the inside 4" x 4" wood support post is
extremely important. Take your time analyzing and measuring where each support post will be
placed. Make sure you are clear of all electric, water, phone lines, etc. prior to digging for piers if
you are not securing your pergola to a concrete patio floor.
Note: It is recommended that you verify local building codes, ordinances and neighborhood
covenants for height restrictions and other local requirements for these structures.
Layout of the Four 4" x 4" Support Post Locations
*Before digging, contact your local surveyor
to determine where you can dig safely.
Measure and mark the width and length of
the desired area to make sure your pergola
will fit and be square (see the dimension as
shown).
Use string lines to measure both diagonal
distances. They must be the same to ensure
a square installation.
