American measurements

What’s even more annoying is that a 2x4 (pronounced two-by-four) isn’t 2 by 4 inches. It’s 1.5 x 3.5 (sometimes even a 1/16 under).

It’s all because of some unfinished lumber bullshit, but it’s still not as confusing as pipe and hose fitting sizing at least.

37???!?!?

Chozo

pronounced two-by-four

Unless you're in the south, in which case it's pronounced "tuba-fur".

silly americans have units of time where there are 60 seconds in a minute, 24 hours in a day, 365 days in a year, and every four years there's an extra leap year! LOL backwards hicks

And I also forgot about the Mainers and their two-by-faws

Can you make it bigger? I don't want to have to get my reading glasses, they're in the other room

Sorry, I'm still having trouble reading it, can you make it a little bit bigger? Maybe also change the colors a bit, like inverted or something

It's because the actual cut is 2x4, and the wood shrinks. The typical shrinkage is known and accounted for. It is a treat when a house has an actual 2x though, i.e., it was cut divided by the shrinkage ratio, or cut dry.

The European mind cannot comprehend that as wood expands, dicks also expands

This makes total sense

You can't convince me that wood shrinks by 35% by crossection. No way.

That’s not from shrinkage (well the 1/16 might be, especially newer fast heated junk at the Homely Despot). It’s from when they mill the rough sawn 2x4 down to “finished size”. You can buy actual 2x4s, but they won’t have the nice planned surfaces or beveled edges.

I’m not wondering why it’s that sized, I’m annoyed why they insist on calling both rough saw and finished items 2x4s.

I had to go back and re-read the history of dimensional lumber. 2x4 was an actual 2x4 cut until recommendations by the Forest Products Laboratory (American Lumber Congress?) in 1919 to balance functional and economic requirements (1 5/8 x 3 5/8). It's neither the shrinkage nor just milling after drying (and if my last 20 trips to big box stores with lumber are any indication, they don't care about cupping or warpage).

Yup, that was wrong.
