2x14 actual size

Dry (19% moisture or less)

1-1/2 × 13-1/4 in

38.1 × 336.6 mm

From the standard, NIST PS 20-25

End view to scale: dashed is the nominal 2x14, filled is the dry dressed size.

Nominal, dry and green

Size	Thickness	Width
Nominal (the name)	2 in	14 in
Dry, minimum	1-1/2 in (38.1 mm)	13-1/4 in (336.6 mm)
Green, minimum	1-9/16 in (39.7 mm)	13-1/2 in (342.9 mm)

A 2x14 is dimension lumber (2 in to under 5 in nominal thickness) under the American Softwood Lumber Standard, NIST PS 20-25. The standard names lumber by its nominal size and sets the smallest it may be once it has been dressed (planed smooth). Lumber dried to 19% moisture content or less is held to the dry size; lumber surfaced green, above 19%, is left a little bigger because it shrinks as it dries.

Board feet in a 2x14

Thickness × width ÷ 12 gives the board feet in each foot of length. By the nominal size that is 2.333 bd ft per foot; by the dry dressed size it is 1.656. Ask your yard which one it prices on.

Length	Nominal bd ft	Actual (dry) bd ft
8 ft	18.67	13.25
10 ft	23.33	16.56
12 ft	28	19.88
16 ft	37.33	26.5

What a 2x14 weighs per foot

One foot of a dry 2x14, 1-1/2 × 13-1/4 in, at 12% moisture content: its volume × the Wood Handbook’s density, 62.43 lb/ft³ × the species’ specific gravity at 12% × 1.12. Multiply by the length for a whole board. Wetter wood weighs more; the wood weight calculator takes any moisture content.

Species	Specific gravity (12%)	Weight per foot
Douglas-fir (coast)	0.48	4.63 lb
Southern pine (loblolly)	0.51	4.92 lb
Western hemlock	0.45	4.34 lb
Eastern white pine	0.35	3.38 lb
White spruce	0.36	3.47 lb
