Take an outlet or switch cover off and look between the drywall and the top of the box to see where the stud is (left or right). That will give you an idea where one is and then you can go from there. Remember that they’re 16” on center and they’re 1 1/2” wide, so you could only be missing the stud by a little bit.

They can be 24” OC, especially in older buildings.

WestWoodworks t1_j9di6v4 wrote

I’m currently renovating a house with 19.2 OC main floor joists, 16 OC main floor studs, 24 OC attic joists and roof rafters.

The attic joists also simply meet end to end in the center over a non-load-bearing 2x4 wall with a single top plate, and zero headers in the doorway openings in said wall.

Point load, and a great many other pretty essential things, basically don’t exist.

Shockingly, it’s one of the straightest, most level and plumb homes I’ve ever worked on… which likely has a lot to do with the fact that it’s all rough cut old growth Douglas Fir. Beautiful lumber, and still really straight.

But yeah… it’s a 1920s house built by the original occupant. The client is that guy’s granddaughter.

19.2 is a metric layout. Some tape measures have little black diamonds on this layout.

48,768 cm doesn't really scream metric to me. 50 cm would be 19.685".

This seems just weird and random? Might've just been what evenly decides one (or some) of the walls or something?

Dsiee t1_j9ekmei wrote

Metric doesn't use 50cm as a common spacing. It is all 300, 450, 600, 900, etc. basically using 1200 mm increments a base metric and then using factors of that.

It isn’t metric. It’s just the only way to divide eight feet into five even parts.

It was meant to simplify, but it failed. Which is why it didn’t really stick.

24" is non-load bearing interior walls. Some interior walls are load bearing depending on the span of your roof. 16" is load bearing.

24 can be load bearing too if you do stacked framing. In regions w low live loads it’s common and more than adequate.

Well "Cheap" framing doesn't sound quite as nice on a quote.

gravitologist t1_j9fkfsb wrote

Well, yes, there is less lumber and thus it’s less expensive. But it is arguably a superior construction method because there is less thermal bridging and so the insulation performs better.

I agree, I used much of the methodology in my recent build but it is still cheaper.

WestWoodworks t1_j9dzwz1 wrote

Eh… not always… not even usually, in my area. At least for interior walls.

Typically only walls perpendicular to the joists are load bearing (though there are rare exceptions).

Load bearing walls should all have proper point load (translating the actual load all the way down to the foundation in a direct path).

Though not always required depending on the region, double top plates are almost always used for load bearing walls, and not for partition (non loading bearing) walls. This is especially noteworthy if you are in a situation like I am right now with 19.2 OC main floor joists, 16 OC main floor studs, and 24 OC joists and rafters in the attic/roof. The double plate gives you a bit of latitude to work with for adequate point load.

For simplicity and consistency’s sake, I frame every wall at 16 OC in a typical stick built home. And that’s typically the case for most other builders in my area.

But, it’s also worth noting that some areas are fully ok with 24 OC 2x4 walls throughout. I definitely don’t recommend it. But you can get away with it in some places without a fuss.

Then, of course you get into engineered lumber, trusses, etc., and shit gets exciting. Suddenly, you have no interior load bearing walls, exterior load bearing walls are mostly header to accommodate an insulting number of floor to ceiling windows… all sorts of tomfoolery and poppycock.

But, anyway… when in doubt consult a structural engineer… don’t be that asshole that has to dig someone’s dead dog out of the rubble of the house you just destroyed by removing something you shouldn’t have. Engineers are often pompous douche bags (at least in my area), but they’ve saved my bacon a few times when things weren’t so cut and dry because of prior shoddy work that disguised major structural issues.

hicow t1_j9e6dd3 wrote

And some newer - it's more efficient to use 2x6s on 24" centers vs 2x4s on 16s, in terms of exposure for exterior walls.

But it's also worth knowing older houses took "on center" measurements as more of a suggestion. I insulated the crawlspace in my 120-year old house last year and the joist spacing was interesting, to say the least.

Mine is from 1850, interior walls are 18" on center, studs the wide way. Exterior are 14" o.c., everything is rough cut chestnut real 2x4, and sheds nails unless you drive dead straight; I think it's half petrified. Balloon frame.

Stud finder is useless, it's all plaster and lath, I'm still replacing knob and tube, slightly complicated by needing to work around the defunct pipes from the gas lighting the knob and tube replaced. I tore out some 1.5" drains that had an actual inside diameter of less than 1/2" due to decades of buildup.

And yet it still feels more solid than any modern house I've been in, the insurance company says replacement cost is 480k (sale price was 109k). 18" thick stone foundation.

Of course it's more solid, it's built with real building materials. Modern "16 inches on center" bullshit was drafted based on using the cheapest 1 3/4x2 7/8 softass yellow pine available on clearance from Lowes. Modern homes are a fucking travesty, I've worked on so many $750k McMansions and $300k shitbox condos that are going to be falling apart in 7 years it's depressing. My ex-wife and I had a mail order Sears house built in the 50s that was more astonishingly well built than literally any new house I've worked on in the past decade.

Dsiee t1_j9ekvjd wrote

Have you worked with the lightweight steel studs? They make a 2x4 look solid af. Steel light framing is awesome when it is well engineered but if it is done wrong it can twist and crumple into a heap.

shikuto t1_j9envmp wrote

I had half of a really long comment drafted up, but I decided to scrap it for something a bit more succinct.

My whole life - albeit only just shy of 28 years - has been around construction. My earliest memories involve working on buildings, either with my parents rehabbing homes, or with my father on job sites where he was a masonry foreman. Taught me how to fire someone when I was three, by having me do it myself. I then went to spend most of the last 10 years as a commercial electrician.

All that to say: yes, I have extensive experience working with steel framing members. I’m aware of many of their pitfalls, and I still think that for my application, they’re vastly superior. It would be all but impossible to find lumber straight and long enough to make studs for most of the rooms of the studio. And having to stitch multiple pieces together in order to get the height adds a ton of time and material costs.

Plus, I’m doing it all myself. Or, as much as I am willing to. Which pretty much means no concrete or Sheetrock finishing. I’ll do all the form work and trenching and rebar for the concrete, but I’m hiring professionals to pour and finish it. For one: concrete sucks. Secondly, that’s a job that I am certain they will do better than me. And the same goes for Sheetrock finishing - I’ll hang it the way it needs to be hung for a recording studio. From there, they’re taping, mudding, sanding, and painting. If the rockers don’t paint, I’ll contract that out as well.

Final pro: when I eventually go to make the structure mixed use, when I open the studio as a business, having steel framing will simplify the process. It isn’t flammable.

To assuage any concerns you may still have: one component of the process that I will not be handling (entirely) on my own is engineering and design. I’m drafting floor plans currently, and then I will hit the engineering tables and websites and forums until I have a solid plan for the structure. Then l’ll draw up a preliminary structural print and send it to some engineering buddies I’ve made over the years for criticism and recommendations. After a few revisions of this - for all of my drawings, not just the structural - I’ll be sending them over to different firms than my friends work at to get them reviewed and stamped.

Sorry for the still rather long response to what was in all likelihood a rhetorical question.

Tl;dr - Yeah, and I’ve taken the pros and cons into consideration, along with a healthy dose of planning for how I’m even going to plan it out.

I'm looking at a house right now (Philly suburbs) that was built in 1849. Everything is level and plumb, which I've never seen before in a house that old. Most fucked-up layout I've ever seen: you go up the stairs and right into the bathroom, and then you access the two bedrooms from the bathroom (the house originally didn't have a bathroom at all, of course). It's one thing to be banging on the bathroom door because you have to go, but another to be banging on the bathroom door because you have to go.

There really wasn’t any sort of cohesive code requirement of any sort until 1950. What we (at least in the US) refer to as the International Building Code wasn’t even established until 2000.

UBC was indeed initiated in 1927, but was only really used in the western United States. It was based in California, if memory serves.

The first national level building code was formed by BOCA (Building Office and Code Administration). The compiled code was first released in 1950, a full 35 years after the inception of the organization.

There are numerous state and regional codes that predate all of the aforementioned, of course.

But the first cohesive compilation of truly national code requirements was indeed in 1950.

WestWoodworks t1_j9e1mn6 wrote

You’d be hard pressed to find a brand new house built last year that’s actually square.

Most people would be shocked at just how rough the rough framing gets.

As a GC that likes to do the framing personally, I try to keep it as square as humanly possible… it isn’t fine woodworking. But I think it should be real close. 89° - 91° is typically not going to give you too much sass at finish time.

If nothing else, it keeps my subs from bitching too much.

On a similar note… I’m constantly surprised by how few framing crews I see that don’t use an eight foot level and a power plane to dial in the final framing. Some of these novice and journeymen guys don’t even know what I’m talking about when I bring it up.

It’s sad how we went from an industry largely made up of craftsmen to a bunch of meth heads pretending to be installers. Most guys will talk a big game about being a craftsman, but their idea of level and plumb has you searching for their meth pipe.

There are still a bunch of really solid guys out here getting the good work done. But it’s so hard to find them in the sea of shitbags.

And, in my experience, shitbags do shitty work. And it shows when you see just how far shit is off square, and considered “good work” these days. Scary, if you ask me.

My first house was built in 1841. None of the studs were the same spacing. In their defense, there wasn’t any 4x8 plywood or anything like that, so they just put the studs wherever they worked out with the wood that they had.

In my neck of the woods, we see a lot of 19.2 OC in homes from that era. But, depending on your region/state, there may have also just been no enforced building codes at the time… meaning it very well could be totally random.

I’ve seen “headers” over main entry doors made out of weird shaped scraps of beadboard of all stupid nonsense.

A lot of times they just used whatever bullshit they had within reach. Especially in depression era buildings.

My parents bought a lake house in Ohio a couple of decades ago. When we gutted the interior, we found that the entire house had been framed with 4' lengths of 2x4 with none of the "studs" at exactly right angles. Most fucked up thing I've ever seen (except maybe the bathrooms in Atlanta where the floor was just non-PT plywood laid directly on the ground) but somehow the builder had ended up with the walls perfectly level and plumb.

Mmm, previous owners. I've seen that move before. It's way easier than removing the plaster and fudging with misaligned studs, but they could've at least drilled some holes and located them. Some people just think wood is wood I guess. One of the first fixes in my house was to put a new light fixture in the kitchen and replace 3/4 of the kitchen ceiling because one of the previous owners thought it okay to mount a big metal light can to lath. And by "mount" I mean cut a hole and just rest it on the lath from above. Half the ceiling was sagging and threatening to cave as a result.

We have lath and plaster construction (house built in 1941), and we have used this stud finder with success. It does a static position calibration step to determine depth of the wall before you scan.

You cannot assume there is a stud 16" from a corner. If the wall length is not an exact multiple of 16" then necessarily there will be a corner where the stud is at some other distance. But if you take a small nail and try at every inch then you will find a stud somewhere along that length. Then you can measure 16" from that one and expect to find the next one. That is, unless there is a door or a large window along the way, in which case distances may have had to be adjusted there as well.

thoang77 t1_j9d523r wrote

Even if it is a true corner, the wall in question might also start behind the adjacent wall so the center of the first reachable stud will be about 12.75” from the corner (assuming 1/2 drywall)

ObligatoryOption t1_j9d5kfn wrote

Right. Someone else here mentioned it: locate a power outlet. The electrical box for them are nailed against a stud, which is either on the left or right side of the box, so you only need to try two positions with a nail to find a first stud. Then measure in 16" multiples to locate the rest.

ItsBaconOclock t1_j9dhtip wrote

That's not a guarantee either. Old work gang boxes can go anywhere, because they clamp onto the wall.

My last house was apparently built by a fun-loving rag-tag band of beer drinking, pot smoking misfit miscreants pulled off the streets and handed hammers to meet booming demand for new housing in the 70s. If your house was built by the same ilk, your studs might not be any consistent number "on center." I had some studs 8" apart and some 4ft apart. Hidden behind caulk and new layers of paint, you would find perforated lines between 1ft and 3ft long where I went in hammering in a brad nail every 1/2" until I found stud. My studs might be 24" apart at the top and 19" apart at the bottom or vise versa. Not a single thing was straight, plumb, or level. Inside the walls we found beer cans and roaches (not insects).

This this this.

Get some very thin nails. Take your best guess at where a stud is by hitting the wall with your hand or use an outlet as described in multiple other posts. Hit it hard if you need to. Tap a brad nail in. If you feel resistance once it penetrates the drywall or plaster, you hit a stud. If not, pull the nail and try again just a bit further left or right. If you are hanging a shelf cover the unnecessary holes with the shelf.

I almost went insane not finding the studs in my garage! As it turns out they layed what seems to be 1"×4"×8' boards horizontally over the studs, then drywall over those. So if you run a stud finder horizontally you'll never find them because there's an air gap between the stud and the drywall.

famous_shaymus t1_j9dbvc5 wrote

Find a patch of a couple feet wide in the general area that you’re wanting to find a stud. Use a finger knuckle to tap on the wall noting the tone that’s made. Move laterally in one direction, continuing to tap the wall. As you get closer to a stud, the tone should get shorter and slightly higher. As you move away from a stud, the tone gets deeper. This method will get yah relatively close to a stud. Then, in an area that’s less conspicuous, maybe near the floorboard, use a small finishing nail to tap into the wall. If it pops through easily, no stud; keep moving in one direction about an inch and a half laterally from the original hole. If you’ve gone maybe 6-8 inches in one direction and by the tone you can tell you’re going in the wrong direction, just pop back to the other side of your original hole and move in that direction.

My last house was built in the 60’s and had shiplap behind the drywall. You might have a similar situation. Maybe take a cover plate off an outlet/switch and see if you can see behind the drywall next to the junction box.

My house was built in 1964. The way I found my studs was to remove the baseboard trim and I was able to see the bottoms of the studs. I made a mark in the center of each one on the drywall that would be concealed by the baseboard trim when I replaced it.

This helped establish the spacing they used when they built the house.

Then I used a 4 foot level to follow them up to the location where I needed to drill a fastener, made a mark and worked from there.

Sometimes I had to cut a bit of drywall away at the bottom to reveal the stud. That's OK, because the baseboard concealed that when I replaced it.

This works if you have trim, if you can remove it easily and if you know how to re-attach it.

Your wall might not have studs. Seriously. I live in a high-rise condo (originally a rental building) built in the 1960s, and here’s what I found when I replaced the tap for my bathtub:

The “wet wall” was made of expanded metal lath and plaster. At roughly 1 foot intervals, there was a vertical piece of U channel formed from heavy sheet metal, roughly 3/4” wide with 3/8” legs. These channels were the closest thing to studs in that wall.

Metal studs are still studs, and can be used as support. They aren't quite as good at holding racking weight, but it's better to be near the upright rather than far from it.

They're super common in commercial construction.

These were not metal studs (note that I listed their dimensions). Metal studs that I’ve seen have roughly the same dimensions as a 2x4.

Oh, true, yeah.

That doesn't sound like a wall but more of a stand off. Like somebody didn't want to back it with plywood but had some random lengths of metal channel 3/4 in wide. That's some wierd "engineering".

that's all that was behind it? That's what is concerning. If I was faking a plywood based wet wall that's how I'd build it, 1 ft centers (In reality I'd use concrete board like a normal person, but not in this bizarro build), but if it's unsupported like you said, that's just crazy. It's a pretend wall.

I've long been of the opinion that builders just make shit up as they go along if you aren't there to police them every day for their bullshit. My sister had her last house constructed and had to have them tear out basically the entire stairwell because of just imbecilic pants on head stupid contstruction that they never would have caught if they hadn't gone through the building with a fine tooth comb almost every close of day.

It gets better. One of the washers between the strainer basket and the tailpiece for my kitchen (double) sink started to leak, literally a 50 cent part. Tailpieces were soldered into drain pipe rather than using slip joints, slight angle so fitting screwed onto strainer basin damaged the basin’s threads, had to replace strainer basin. Did you know that between the 1960s and the 1990s, there was a change in strainer basins - they now project roughly 1/2” less below the bottom of the sink? Had to replace both strainer basins and crossover pipe because a 50 cent washer was installed in a manner where it couldn’t be replaced.

All the lights and half the outlets are on one circuit. One of the outlets on that circuit is near floor level where the fridge was when I bought the place (from the cabinets, it looks like that space was intended for the fridge - fridges should be on their own circuit). I moved the fridge to what looked like where the ironing board was supposed to be set up (outlet on its own circuit). Previous owner had painted over many switches/outlets, so I was replacing them. Removed fuse from circuit for “old fridge” outlet, was detaching wires from the outlet. Detached one of the wires from the neutral side, there was a spark. The neutral return for another circuit went into one of the silver screws on this outlet and out of the other. Set up a pigtail - both wires and a short one go into a wire nut, short one goes to new outlet, so any future outlet replacement won’t leave a loose live wire.

Opened a few walls in my 1960s house to find interior door headers supported by the 1x pine doorjambs, just toenailed into the king studs, no jacks. My hall closet only opens halfway and my bedroom door won't close, so I'm guessing they're all like that. They're not load bearing walls, so who cares, right? /s

Replaced the wax ring in my basement bathroom. Flange is rotated 90° (so bolts feed through the holes, not the t-slots) and welded into the cast-iron drain. Holes are only accessible from underneath, through the floor.

The way I have found studs in my place is taping a piece of a fridge magnet onto some dental floss.

If nothing else works, drill a small, easily filled hole in the drywall near where you want to mount the shelf supports. Bend a wire hanger (remember those?) to a 90° angle and thread it through the hole.

When you rotate the hanger it will hit the stud and you should be able to tell where the stud is with enough precision to attach a shelf mount to it. Or maybe you'll get lucky with the 1st hole...

SwellJoe t1_j9easjg wrote

I bought a house last year, and in several rooms I could not find studs on any interior walls. Baffling. I'd find screws, but then when I'd drill I'd find no stud behind it. Weirdest thing.

Finally realized somewhere along the way drywall sheets were hung over the old lath and plaster walls, so the studs are far enough back to be undetectable with magnetism. The screws are just kind of random and only sink into the previous wall, not the studs. I've considered pulling off the drywall to see what's actually going on back there (I assume water damage, as many places in the house have water damage), but then I'd have a bunch of drywall to replace, in addition to everything else that needs doing.

If there is an outlet on that wall it should be attached to one side of a stud. It gives you a starting point.

Using the small hole that missed the stud, unbend a wire hanger and fish it in the hole sideways until you hit a stud. Mark the hanger and pull it out and measure that distance on the face of the wall. Repeat in opposite direction to find adjacent stud. Measure in between two to find the stud spacing down the wall. Some homes were built with balloon framing which is generally 24" spacing rather than the now typical 16".

I installed security systems for a summer, and we had to drill a finger-sized hole behind the panel to drop the wire down the stud space to pop out at an outlet for the plug. I was having the absolute worst time getting the pull, ended up with a palm-sized hole (still fine, it would be hidden by the panel) and couldn't make it. With the customer's blessing, my manager (who had come to find out what was taking me so long) cut a hole big enough to look inside the wall. The framer had decided to slant a stud from bottom left to top right of the "cell" for some idiot reason, and the angle was slight enough that we couldn't sense it by touch. Moral of the story, don't trust that the framer from a full sixty years ago did what they were supposed to do, or that nothing has been changed since then.

Very carefully pull off a piece of the baseboard. You can cut a 1/4” - 1/2” channel where the trim will cover it.

Once you find them, replace the baseboard using a little bit of Liquid Nails.

Just be careful if the top has been sealed up with caulking/paint. Use a sharp razor knife to very carefully slice that along the top edge.

Get a stronger stud finder. My walls are drywall then plaster. Almost 2” thick in spots. A regular stud finder does nothing for me, but I’ve got a higher end one that can find them.

Otherwise the old outlet box trick is a good way to start.

Measuring 16” from the corner isn’t a good way because the wall probably isn’t a perfect multiple of 16”. That corner could have been the end of the wall when they framed it. A 170” wall from the tail end is going to have studs at 10”, 26”, 42”, etc

Simply enough just use a strong magnet, it will be attracted to the nails in the studs and boom, you find your studs. From there you can do it a couple more times and use logical deduction to figure out how far apart the studs are. just because 16" or 12" is standard depending where you are or what wall type it is doesn't mean everyone followed every rule back then.

Use the magnet method. Drywall is nailed on to studs. If you use magents and locate a column of three evenly spaced nails that line up vertically, you can be pretty certain that there's a stud there, especially if there's another column to the left or the right about 16" apart.

Vegas_off_the_Strip t1_j9e1uxa wrote

often in the corners there is more than one support beam so the 16" does not start at the corner.

Also, it could have started from the opposite corner. Very commonly the last stud in a wall might only be 8 or 10 inches or whatever from the corner because they started at the opposite wall.

Also, sometimes there's a window or door or something that causes there to be a support beam in a place that throws off the 16" from the wall. So, you just need to find one in the middle of the wall. and then go 16" from there.

Also, older construction sometimes had studs at 24".

If you're going to use nails to find it, then I recommend getting a very thin nail and then trying to locate the stud with as little damage as possible. If the wall is white or off white you can use toothpast to fill in the small holes. However, getting a stud finder is the best way and they are cheap.

> Stud finder finds nothing

Stud finders, unless you spent some cash, are notoriously unreliable. Your experience is not surprising--unfortunate, but not surprising. Try a magnet to locate the drywall screws, buy a better fineder, or use another method.

> Measured out 16" from the corner and drilled a small hole, went straight through.

Even if your studs are 16" on center, that doesn't mean they are 16" from any point or feature. The wall may start anywhere inside or even beyond the corner, or the studs might have been laid out to make cutting in windows, doorways, or other features easy.

Once you have located a stud, you can usually find other studs this way, but this won't necessarily help you find your first stud.

Your studs might also be 24" on center, depending on the wall specs, or might even shift to make framing easier. The code is a minimum, not a rule.


  • Magnets are my go-to, you can even find magnet-based stud finders.

  • Most power receptacles and light switches will be installed against a stud, so look to either side (this is very NOT true for phone, cable, or other low-voltage outlets, or anything installed after construction was complete).

  • Finally, knocking along the wall will usually let you center in on a stud.

None of these is going to give you a "right there", but you can usually get a 4-6" target and narrow down from there. The nails are a good check.

You can knock on the wall and listen to the sound. The empty space between studs will have a lower pitch and the stud will have a shallow pitch. Imprecise to an untrained ear, but it will give you a hint.

You can also look at the wall itself. There are often visible signs of where the nails were hammered in to attach the drywall in the first place.
