Coverage Calculations
Siding and paneling are
usually sold either by the lineal
(running) foot or by the board
foot.
To simplify cost and coverage estimations, select the
appropriate factor from the
table at right according to how
the material is priced. The factors provided in the table can
be used to calculate the
amount of siding required either
in lineal feet or in board feet.
In either case, the square
footage of the area to be
covered is calculated first, then
multiplied by the appropriate
factor.

Procedure:
A) Calculate the square footage
in walls:
length x width = sq. ft.
B) Calculate, and then subtract,
the square footage of
openings. Now add 10% for
trim and waste.
C) Multiply the result by either
the factor for lineal feet or
the factor for board feet.

The exposed face width will vary depending on
size selected and on how the boards-and-battens
or boards-on-boards are applied. Minimum overlap is ¹₂". Determine the exposed face, then refer
to footnotes to calculate factor.
1 Lineal Foot Factor is derived by dividing 12" by the exposed face width.
2 Board Foot Factor is derived by dividing the nominal width by the exposed face width and is based on
nominal 1" stock, except log cabin. Log cabin is based on 2" thickness. For nominal 1¹₂" log cabin, multiply
by .75.
Note: Factors do not include any allowance for trim or waste and do not apply to diagonal installations. A
10% allowance (for trim and waste) should be added to the square footage required before the factors are
used. Refer to Procedure at left.
D) Multiply the total footage
required by price.

Grade Rule Paragraph
Numbers for
Reference & Specifying
1 Equivalent grades, under the same paragraph numbers in WWPA Rules, are available in Idaho White Pine. Refer to Western Lumber
Grading Rules.
2 Western Wood Products Association’s Western Lumber Grading Rules.
3 West Coast Lumber Inspection Bureau’s West Coast Lumber Standard Grading Rules.
4 National Lumber Grades Authority’s Standard Grading Rules for Canadian Lumber.
5 Some clear grades may be specified VG (vertical grain). Common practice is to ship orders as a combination of vertical and flat grain,
unless specified otherwise.
6 The widely used marketing term, “STK” usually describes a combination of Select Knotty and Quality Knotty, sometimes marketed with
approximately 15% of the order in Quality Knotty.
The grade names in bold face type are the most widely available grades. These are often specified as a grade combination
that includes some portion of material in the next higher grade; i.e. C&Btr Select, D&Btr Select, A&Btr Cedar, 2&Btr Common, 3&Btr
Common or Std&Btr (Standard & Better).
