Wood beam sizes

[JStructsteel]

Do beam sizes for dimensional lumber follow standard dimensional lumber?

i.e a 10x10 would be 9.25x9.25?

Anyone have a good chart for sizing?

Yes... 3-1/2, 5-1/4,5-1/2, 7-1/4, etc...


Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

based on the American Wood Council National Design Specification, a 10X10 timber would be 9 1/2" sqaure.
Table 1B

search "table 1b section properties of standard dressed sawn lumber"

I think it is 3-1/2 and 5-1/2 before it changes to quarters (7-1/4, 9-1/4 etc).

Posts may not be the same as 2x lumber.

Yup... my oversight.
