Does anyone have or know where to get a wood grading chart. (I guess that is what it’s called) I was looking at a catalog for wood and I need some clarifacation.


For example on this picture. What is C select, D Sel&Btr, C&Btr Rough?


And in this picture: Sel&Brt, No. 1 Com, No.2 Com?

Is there a chart out there that can “translate” this for me?

-- While teaching a class, a gentlemen once asked me: "When chip carving an intricate design, what do you do when you are almost finished and the wood breaks off?" I replied "Cover the kids ears."

First off, you should probably post this sort of questions as a forum topic. You’ll get more responses and that is really the proper place for it. No harm done, but in the future, try to post questions like this as a forum topics.

Second off,

No. 2 com = number 2 common. That means a lot of knots and wood that is not that high a quality. Fine for small things like cutting boards, or rustic projects where you want knots and cracks, etc.

No. 1 com = number 1 common. A little better than number 2 common. Still some knots, but more usable areas of wood. Still not tabletop quality boards, but you can do more with these than no 2 common.

Sel+Btr = Select and better. These are your furniture grade boards. Large areas of good looking wood that is knotless and otherwise goodlooking.

The grades are computed based on square footage of board without blemishes. That is a simple way of saying it, but that is basically how it works.

I don’t know about the gradings in the upper photo. Hopefully someone will chime in on that. Good luck.

Hey Chip,

Here is a link to a pdf about the NHLA lumber grading rules adopted by the US hardwood industry.
It has comparison pictures of common hardwoods which lets you get a feel for the different grades.

There are some good youtube videos on grading lumber too. Helps the lumber grading guide books like Steve linked make more sense.

I think you can move a blog to a forum post too, or at least you used to be able to.

Thanks guys.

Also, a big thanks SPalm, that is what I was looking for.

P.S. I will be more careful when I post next time. Make sure I choose the right place. :)
