Qustion on wood size??

I bought a pattern and the parts list for the wood states for example: 3/4 x 3/4 x 2 1/4 inch stock. I am not sure if I go into the store and get the wood that states 3/4 inch or would I get the one that states 1 inch that really measures 3/4 inch. I know its kind of a stupid question but for some reason it was boggleing my mind as to which size to really get. Thanks for any help!!

Quality lumber is measured in exact measurements such as the 3/4" listed. Construction lumber is measured in nominal measurements. Either will work for you because they are both 3/4" finished thickness. However, if you go buy a "1x3" construction type board the finished thickness will be 3/4" x 2 1/2" so you will have to rip it down for sure.

Yeah that can get confusing.

If the plans state 3/4" thick, and 2 1/2" wide that is the final thickness they intend you to use. So you would buy a 1x3 (which is really 3/4" x 2 1/2" usually). Or a buy 1x4 (which is 3/4" x 3 1/2" usually) and rip it down to the specified size.

Measurements used to mean something before downsizing. 2x4's were really 2x4! 3/4 was really 3/4". 4/4 was really 1". 5/4 was really 1 1/4". Now it seems those meanings are lost, and when you ask for something 4/4, you get a 3/4" thickness... ask for 5/4, you get something 1" thick, and if you want something that's 1 1/4" thick you need to ask for 6/4. Which is really stupid, IMO. (Unless the old timer I learned it from and everyone else at the local lumberyards had it backwards to begin with!)

Now I got 2 different answers and I am really confused. So when I go into the store am I looking for something marked 3/4 inch or something that measures 3/4 inch? Does it mean anything, on the list of wood I need, where after the wood size, it states "STOCK"? Does stock mean anything in particular??? Thanks guys!!

i don't think they are 2 different answers. We both said get a 1x3. it will measure 3/4" x 2 1/2". You said you needed something 2 1/4" wide. So you would need to take that 1x3 and rip it on a table saw so that it's 2 1/4" since a 1x3 is 2 1/2" wide. If the store does not sell 1x3 you would get a 1x4 and rip it on a table saw so that it's 2 1/4" wide. Make sense?

I would think that if your plans say "stock" it would mean that you can buy a product that exact size. (i'm guessing, since I can't see your plans.) Like if the plans called for 3/4" x 3 1/2" x 4', that would be a stock item, since stores sell 1x4's that measure exactly 3/4 x 3 1/2"... as opposed to a "custom" item - one that you need to cut in order to make it the specified size.

To ease your mind, take a small tape measure to the store with you and measure the lumber. My eyesight isn't the best to so I tend to look at the lumber [which I recognize by sight] instead of the sign that tells the size..... but I assume a 2x4 is listed as a 2x4 even though it's actually 1.5"x3.5"

Lumber is cut to the full size at the saw mill. After it's dried [wood shrinks a little when dry] and planed to make it smooth and insure it's all uniform in size - that's how the smaller size comes about.
