studs pre-cut to 92 5/8"...why?

johncollins's picture

Does anyone know why pre-cut studs are 92 5/8"?  You add two top plates and a sill and you get 97 1/8"  I can see an extra 1/2" or maybe even 1" so you don't have to cut down your sheetrock, but what about that mysterious 1/8"...?  Why not a round number like 92" or 92 1/2"?

It's because the company that first started pre-cutting studs couldn't close the tailgate on their 1943 delivery truck, so they cut all the studs so they would fit in the bed.

I was eating a snack when I read your response and by god if I didn't almost choke to death because I instantly started laughing. GOOD ONE!!!!!!

If at first you don't succeed, try using a hammer next time...everything needs some extra persuasion from time to time.  -ME

Glad I could entertain everyone.  It's not very often I get to be the first to reply.


Oh, and my reason is the correct one.

92 AND 5/8THS


this summer not only did prices go up a lot but quality went way donw hill, boy what we used to call #3 is now #2 or better


but we had trouble getting consistent precuts


92 5/8ths could be anywher from 92 to 93, dont know how many times we had to "adjsut something" because of one stud being 92 ands the one next to it being 93

I still spend the little difference for full 8's..just so I have the option of which knotty end(s) to cut off..seems precuts ALWAYS have a big azz knot when I have to toenail it..I hate that. When I am the cut man, I ALWAYS think about who has to nail it, and hardly ever give a guy say nailing gable studs a bad end. If I do I expect it to come back at me, cuz that's what I do if I get a crappy end..throw it back down and have em cut another. There is no excuse for a cut man to not make a nailers job a little easier..gotta measure and cut it anyway, why not give a clean end?

By now we all did the math   92- 5/8"+ 4.5"(3 plates) =97-1/8"


Now cap the ceiling with 1/2" rock and you are down to 96-5/8".


Now put down 5/8" partical board in carpet areas & plwood in vinal areas & that brings you back to 96".


Now most builders today only put down a single sub floor. I still use a double 5/8" system.


thats all I know.

you put plywood in your non carpet areas ? doesnt all the grains knotholes etc show through the vinyl

(post #59684, reply #16 of 24)

Not with AC, Latex seams & nail heads, sand & clean. or you can lauan over the plywood, then vinal.

(post #59684, reply #21 of 24)

wow, seems expensive to use ac plywood under vinyl. but i guess in high mositure areas it might be worth it

(post #59684, reply #22 of 24)

AC plywood isn't really considered good enough for use under vinyl because it often has voids in the inside layers that can telegraph through, in various ways, with time. 1/4" luan plywood is preferred because it has no voids.

I agree on the longer lengths. I worked in sawmills for a bunch of years and, from observation then and my experience as an end user now, shorter lengths are often the result of an attempt to get every inch out of a chunk of wood to meet market specs.


In fact, I seldom even buy 8's anymore, especially when buying units....16's usually yield a better piece overall.  The lengths are never consistent anyway, so jobsite trimming has become part of the building process if you want good fits.


BTW, it used to be that. when grading was performed by real humans, knots at the end of a board were sent back to a "hula" saw for retrim, but many of the small-log automated sawmills of today cutting young plantation wood, feature scan technology to determine grade and trim on commodity items, like common framing lumber....and I have yet to meet a scanner, or the Dweeb who programmed it who's ever had a gun nail blow up a knot at the end of a stud.

Dig it, early job for me was a pallet mill..I made 720 pallets a day, NOT Skids..got paid pc. rate BY THE NAIL..0011 cents per nail.. a 40x48 pallet has 84 nails..(if it is a standard with 4way notches)...thats .0924cents a pallet..66.50 a day..GLAD THEM DAYS ARE OVER..


when we ran out of stock for the nailing machine I would run a 'multiple end trimmer'   5 radial arm type saws that could be set at say, 48'' between blades, slap up 16' oak 2x4's on the chain feed and whoosh,,4 at 48''..lotta fun low pay great experiance..I know how to read a knot..most are bad news.

Great story!  (I love 'sweatshop' tales!).


I had a friend (who has since passed on), a Black guy who could spin a yarn and have everyone ROTF and in tears before even reaching any kind of a punchline.


He spent some time as a foreman in a Twinky factory where he oversaw about a dozen women whose job it was to pick the Twinkies off a moving belt and set them in fours in their little package.  There was a technique for doing this efficiently which involved grasping the Twinkies between one's spread fingers and setting them in the little paper tray all in one smooth motion.....all day long, 5 days a week, 52 weeks a year.


Once there was a Flu epidemic going around and my friend's crew was so shorthanded that, to meet production, he had to join the Twinkie crew on the belt.


Prior to this particular day, he had no appreciation for what these workers did;  his biggest concerns were attendance, length of breaks, timekeeping, safety meetings, etc.


But after ONE DAY on the Twinkie line, with cramping fingers and visual disorientation from staring at a moving belt for hours, he realized he had been supervising humans of much greater stamina, strength and skill than he....and soon after, took up a career of bus driving....

The "price up and quality down" may have something to do with the U.S gov't. tarriffs on Cdn. softwood lumber!!  And I thought we had a free trade agreement.

Now subtract 5/8" for ceiling rock and what do you have left for clearance at the bottom?<G>

(post #59684, reply #3 of 24)

Duh... now I get it.  Thanks

(post #59684, reply #4 of 24)

or add 3/4 strapping and 1/2 DW and there ya go (in Ont. and P.Q. you rarely see  5/8 on ceilings `cept for some firecode stuff)

(post #59684, reply #5 of 24)

I'm not sure,  but think it has something to do with the black diamonds on the tape measure...

(post #59684, reply #6 of 24)

Dem black diamonds?  Divide 96 by 5 and waddya get?  It was a first year arch. student pointed that out to my and a  friend. His name was Eddie, and ever since then,(12 years ago), we been calling them Eddie-marks. (or the units are simply`Èddies`)

(post #59684, reply #7 of 24)

In NC, they are all 93".  I think I like the 92 5/6 dimension better....

92 5/8?


Where is that?  Out here in CA (Orange County) we seem to be using 92.25" studs.  You must have volume ceilings <g>.


An exception was the chap that found the full 8' 2x4s and built all the door and window units for one of our homes from that stuff.  Be nice if they would paint the ends different colors.

We just discussed this in my Construction Technology Class.  I always assumed it went back to the underlayment and subfloor days ( I started in the 70's when 3/4" T & G was the standard. 92 5/8 plus 4 1/2 = 97 1/8, with a 5/8" ceiling and a 1/2" underlayment added at the end, you wound up with a true 8' ceiling.  It always sounded logical to me.
