Densities for Common Residential Construction Materials

Articles > Densities for Common Residential Construction Materials
Material Density 
Aluminum 170 pcf
Copper 556 pcf
Steel 492 pcf
Concrete (normal weight with light reinforcement) 145–150 pcf
Masonry, grout 140 pcf
Masonry, brick 100–130 pcf
Masonry, concrete 85–135 pcf
Glass 160 pcf
Wood (approximately 10 percent moisture content)  

spruce-pine-fir (G = 0.42)

29 pcf

spruce-pine-fir, south (G = 0.36)

25 pcf

southern yellow pine (G = 0.55)

38 pcf

Douglas fir–larch (G = 0.5)

34 pcf

hem-fir (G = 0.43)

30 pcf

mixed oak (G = 0.68)

47 pcf
Water 62.4 pcf
Structural wood panels  


36 pcf

oriented strand board

36 pcf
Gypsum board 48 pcf


96 pcf


82 pcf
Sand, dry 90 pcf
Gravel, dry 105 pcf

Note: The equilibrium moisture content of lumber is usually not more than 10 percent in protected building construction. The specific gravity, G, is the decimal fraction of dry wood density relative to that of water. Therefore, at a 10 percent moisture content, the density of wood is 1.1(G)(62.4 lbs/ft3). The values given are representative of average densities and may easily vary by as much as 15 percent depending on lumber grade and other factors.
