Now I know, but I cheated.

There has never been such a thing as a true 2x4; the only time it's that size when it's still in the log. You lose saw kerf when sawing, and more when it's planed. The log scale rules are based on 1/4 inch kerf...

May be a regional/application thing.

When I buy 8/4 lumber, if it's not MORE than 2" I would send it back. Never happened yet, and I would bet I've bought a million feet of 2" material if not more in the last 30 years. Similarly, 6/4, 5/4 and 4/4 - in just the last 10 years I have bought in well over 2 million BF. Every single board has been OVER stated thickness - i.e. "4/4" = more than 1", generally 1-1/16" or so, etc.

Are you buying dressed construction studs?

If you really want to twist somebody around, ask them the length of a pre-cut stud.



Hint, 96" it ain't.

Can be... but for some reason 92 5/8in is stuck in my head. Your stack up of the floor and ceiling plates gets you to a little over 8ft for your wall height and then the ceiling and floors eat in to the true height so you end up with about a 8ft ceiling.

Without using Barney (Google) is it 84 or 81 inches?

The standard length of a "pre-cut" stud is 92 5/8"... if the exterior and other bearing walls are at 8' this will give about 3/4" clearance under trusses etc. for non load bearing interior partitions...

92 5/8 is what they sell around here. So with a bottom plate and a dual top plate with a piece of 5/8 sheetrock on the ceiling it is about right for 8 foot sheetrock walls with the sheetrock off of the sub floor. Especially important if the sub floor is concrete.

When building on concrete I prefer to put a strip of tar paper down as a moisture barrier. That's not germaine to the length of the stud, just an observation.

Chiggers bore into the skin.

Chiggers do not bore into the skin.

I've read both. I've looked at pictures that claim to explain the second. My ankles tell me the first. No one will convince me otherwise.

If standard framing material is being used...using a double top plate on walls framed with "pre-cut" studs (92 5/8")...Walls will not fit under an 8' ceiling...92 5/8" + 3" for top and bottom plates = 95 5/8"...It is not common to hang ceilings before interior partitions are framed/stood...

If double top plates are required typical pre-cut studs will require further cutting...Also...unless it is a designed bearing wall...any other interior walls are not supposed to be framed up tight under trusses etc...they should be about 1/2"- 3/4" below but close enough to so top plates can be fixed with a framing nail etc. to plumb them...

I’m going to guess it’s 96 minus 1.5x3 minus 1/2 for drywall and maybe a tad more for a gap at the bottom of the drywall. So 91 or a tad less. Btw the local lumber yard sells studs or actual length stuff. You might claim its to save a few cents but it’s not. Building a wall 8.5 isn’t acceptable. Cutting 8’ boards shorter is a lot of work of extra work.
