Where can I find tolerances and measurements of green and dry lumber?
The Western Wood Products lumber guide can be downloaded from their web site at www.wwpa.org. You can find sizes of dry and green (unseasoned) lumber on page 13 of the guide. There is also quite a bit of very good information in the guide. Keep in mind that this is only one species group (see the last page of the guide for species included under the “Western Woods” category). You will have to contact other wood marketing agencies or any grading rules if you require information for any other species not listed there.
