Building Decks
What You Need and How Many: A Materials
Worksheet
Key Measurements
First, refer to your deck design and to the
adjacent illustration. Then record your deck’s
measurements below. You will use these
measurements to compile your materials list.
Deck Length (along the house): ......... ft.
Deck width (out from the house): ..... ft.
Deck height (distance from ground
to top of decking): ............................... ft.
You may need to use the worksheet on the
right to determine the following values
Joist span (distance from house to
center of beam): .................................. ft.
Joist spacing (distance between
joist centers): ....................................... ft.
Beam span (distance between
post centers): ...................................... ft.
Now. you will use these measurements to
compile your materials list.
Note: The following tables are based on a live load
of 60 pounds per square foot. If your building code
permits design with lighter loads, spans may be
longer. In this case, or if your deck will experience
heavier loads, consult an engineer or your lumber
dealer for design assistance.
In the equations below, round all fractions to
the next highest whole number.
Deck Boards
1. First, use the equation below to determine
how many lineal feet of decking lumber you
will need.
For 2x4 decking:
(deck width in inches ÷÷ 11")
X (3 x deck length) = lin. ft.
For 2x6 decking:
(deck width in inches ÷÷ 11")
X (2 x deck length) = lin. ft.

When you've prepared a sketch of your new
deck (refer to the illustration materials
worksheet on this page for measurements) we
will assume that the deck will be attached to
the house and that you will be using treated
hem/fir lumber. This worksheet is for a deck
with no railing or stairs. See "Advanced
Decking Techniques" for information about
these sometimes necessary items.
