You need help with long division? Hard pass. Actual size: dimensions at time of manufacture. You want help picking out a rug or putting together a mean peanut and butter sandwich? I’m your gal (the secret is to add pretzels and banana slices. a nominal 8x8 timber has a minimum finished size of 7.25' x 7.25'), most timbers over 7' are finished with 1/2' removed. It is much easier to say Gimme a 1 x 4 than it is to say Gimme a. While NIST Publication PS20indicates that nominal 7' to 15' thick timbers should have 3/4' removed for a finished dimension (e.g. The standard finished size is 3/4 x 3-1/2. Now, mathematics is not my spiritual gifting. Softwood lumber that has a thickness over 5' is called timber. I refer to this chart when I’m sketching out plans for projects, and hopefully, it’ll help you too.

Historically, when boards were cut and milled to be used for lumber, they were cut at 2” by 4.” By the time they underwent the drying and planing process, they came out to be 1 ½ by 3 ½.” Today’s harvesting and milling processes have changed, but the lumber dimensions still come out to those old standard sizes we’ve all become accustomed to. Actual Dimensions of a 2×8 Board Advertised 2×8 board actually has a dimension of 1 ½ by 7 ¼. Isn’t calling a board a 2 x 4 when its actually not that size like calling a cauliflower-crusted, marinara and cheese-topped oven disaster a pizza? (Side note: we all know that’s not really a pizza and anyone who tries to invite me over for “pizza” and then proceeds to serve me that cauliflower-cheese-Frankenstein mess will never be a real friend of mine.) So why do they do it? ![]() If you’re a simple soul like me, you’re probably asking why the hell anyone would play such a mean prank on the world. Go ahead and laugh at me, but when I was first beginning to build things, I thought a 2 x 4 was actually 2” by 4.” If you’re new to building things, this may be news to you, but the nominal lumber dimensions (the name by which they’re sold and commonly called, ex- 2 x 4, 1 x 4, etc.) is not the same as the actual lumber dimensions. ![]() Nothing ruins a set of DIY plans more quickly than not accounting for the actual size of the boards you’re using.
