Step 2: Measure the Width (Projection)
Place your tape measure on the right side and against the house wall,
measure straight out to a point on your concrete or wood deck you would like the patio cover POST to be placed. Now,
repeat the same steps for the left side. Newport Patio Covers, Lattice Patio Covers and Lattice Patio Covers have
a 1 - 2 foot overhang past the the post and header beam. You should add the overhang to measurement of the post
and beam location. For instance if you measured from the house wall out and wanted the post to be 10' 0" from the
hosue wall and wanted a 2' 0" overhang. Then your patio cover projection would be 12' 0" by as long as you want it
to be.
(Traditional or Classic Patio Covers do not have overhangs, the patio cover and post placment end at the
same measurement)

Step 1: Measure the Height
Place your tape measure on the concrete slab or wood deck and measure to top of
your eave then add 12" (in). The maximum height for our patio covers is 12' 0" at the highest point.
General
Notes: Our Patio Covers are installed with a 1/2" slope for every 12" of width, for example a patio cover with a 10'0"
width (projection) will have a 5" drop for water drainage. Laguna Lattice Patio Covers do not have slope and are installed level.
Step 3: Length
Place your tape measure at the approximate location of where your patio cover will start.
Measure from one end to the other. You do not have to add for any overhang. Your patio cover will be made to the size
you want.
Step 4: How Many Posts?
The distance between posts depends on the distance the patio cover will span from
the eave to the front beam. We have listed some of the standard O.C. (On Center) dimensions based on the projection and
attaching to an existing concrete patio slab. The minimum requirement for a concrete slab is 4". In most cases all concrete
patios are installed with a minimum thickness of 4".
Standard O.C. (On Center) Post Spacing
What is the tributary?
The tributary distance is 1/2 of the clear span plus
the over hang. Foreinstance if the distance to the beam is 12' 0" and the overhang is 1' 0". the tributary would
be 7' 0"
Clear Span 12' 0" X .5 = 6' 0" + 1' 0" = 7' 0"
The distance between posts depends on the
distance the patio cover will span from the house to the beam. This dimension is called the "Clear Span". The
minimum requirement for a concrete slab is 4". In most cases all concrete patios are installed with a minimum thickness
of 4".
