Calculate Wall Frame Quantities

Calculate Wall Frame Quantities


G’day, welcome back to Buildsum and This time i want to go through the process of Calculating the materials for your wall frames So as you can, see here I’ve got a typical floor plan, with the dimensions provided and Really, what you, want to do is for every wall frame you actually Want to go through and calculate every wall frame individually i mean there are, some quick tricks that you could, do but Yeah, it’s a little bit more accurate if you do every wall frame individually so obviously that’s going to be a long Process it’s not just gonna take a couple of minutes it’s going to be quite detailed So what i want to, do i’m just going to go, through this example i’m only Going to concentrate on two wall frames so This, one here which has just got all studs there’s no openings or anything in it and This, wall here which obviously there’s a window opening in that wall so You know once i’ve done that you could then go through and calculate the rest of the wall frames and as you see there’s a little bit of work in it So I’ve got Wall 1 down here no studs sorry, no window and wall 2 has got a windows So the first thing, we need to work out is our plates top and bottom plate and simply they are just that however long, your wall is So, what I’ve, also done Before i started i’ve actually gone through and identified How, long i’m gonna, make, my, walls or where i’m going to join them and quite commonly, you’ll try and join on in an intersection Just an easy place to join them or if you can’t do it on intersection Like, down here i’ve just nominated a spot just away, from the window. In the other wall So i can just easily, but the two wall plates together Okay, so i’ve already i’ve worked out roughly, where i’m going to join my
Wall plate so the first thing the plates. Length of the wall and obviously one plate at the bottom of the wall one plate at the top of the wall so for Wall 1 It’s 3.410m long Obviously i’m just going to order two at 3.6 rpunding that up to the next orderable length and Wall 2 3.640 long I’m gonna order 2 at 3.9 okay, so That’s the wall plates so it’s pretty easy So the next one and even easier than that is the noggins and For the walls that I’ve got a window Because you don’t have noggins running through the middle of your window Then the timber that would have been used for your noggins drops down and becomes your window sill Okay, so as i said their noggin sills and door trimmers if you’ve got a Door in the wall that the material that we’re allowing, would just get lifted up to the top of the doorway So, that’s just easy, that’s simply the length of the wall Okay, our noggins are supposed to be in at every 1350 on 1.350 m up the wall so for walls up to 2.7m high One row of noggins is fine For anything, above 2.7 you’d have to add in two rows of noggins and so you’d have to allow that row of noggins twice But this wall we’ve only got 2.4 m ceilings so we only need one row of noggins Again, pretty similar to our plates We just put the length of the wall in now, some people would say, well why Not just allow our three lengths for their plates which in a lot of cases you could, do However in noggins don’t have to be the same size as your framing material, your studs, they can be narrower So in some cases just better to separate that out Alright, but it’s not that uncommon quite common to just allow our three plate lengths till there for your noggins as, well Alright, so there’s our horizontal members their plates in our noggins and our sill and door trimmers, now let’s have a look at our studs Okay, so for our studs the formula is the length of the wall divided by our stud spacing,(600 or 450 )plus one Because when we divide wall by stud spacing, we’re actually working at the spaces in between and Then if the wall has any intersections or any walls butting into it we need to allow another stud for each intersection because, we have double studs wherever the walls intersect so for wall 1 1.340 meters long divided by 600 our start spacing that gives you 5. something studs Now obviously you can’t have our point of a stud so we have to round that up to 6 studs Then, we add the one for the end and with Wall 1 there’s no Walls that butt into it anyway it actually butts into this wall so there’s no Intersection so we end up with 7 studs and that means We would order 7 studs at 2.4 all right we’ve got a 2.4m wall height our studs will be slightly shorter than that, okay That i’ve got another video on that and i’ll put a link in the description But for an orderable length you’d have to order 2.4 for wall 2 all right 3.640 m long divided by 600 again that gives you around 5. something studs So you’re, gonna Say 6 studs For that part of the equation plus our 1 that gives you 7 and then with Wall two you have this wall here it butts in there and This wall here it butts in there so, we have 2 intersections So our 7 plus 2 gives us 9 studs so 9 at 2.4 for our studs So they’re just our common studs the other studs, we have to worry, about or what are our Jamb studs and Again, I’ve doing the Jamb studs separately because Commonly they’re, not the same size as our standard Common studs they could be, if we’re using 35mm Common studs our jamb studs might be 45mm Thick And as a general rule, again, two per window for every window You’d put in 2, just allow to jamb studs If that window, was say wider than 2.4m i would probably, allow 4 Jamb Studs All right and the wider the opening gets the more Jamb studs you are going to have to allow By the time you get up to have until they are three and four then you’ve probably Have to do a little bit more research in the timber framing guide to see just how. Many Jamb studs you would actually need So as a general rule for any window Opening that’s sort of less than 2.4m just to lay out two Jamb Studs per window So obviously with wall one there’s no window. So there’s no jamb studs wall 2, one window so 2jamb studs and they’re going to be the same length even though they’re going
to sit under a lintel you know the chances of having a lintel that’s wide enough to get us down to the next orderable size is pretty slim All right, so we’re just all out two at. 2.4. for our Jamb studs and The last thing, we need to work out is our lintels So the lintel sits over the window, and you’re going to get given a window Opening or on your actual plan they might just might just give you Like a reference number which goes which you have to refer back to the Window Schedule to get your opening size Okay, so that’s the actual clear space That the windows, going to fit into now Obviously your lintels going to have to be a little bit wider than that because it’s got to sit on top of your Jamb studs Okay, so in this case i’m going to, assume that, my Jamb studs are 45mm wide So i’m going to take the length of the opening add 45 on either side for my supports that gives me 90mm and that will give me the length i need for my lintel so No, no window in Wall 1 so I don’t have to worry about that so wall 2 So my 2.8 my 2.008 For my opening Plus, 90mm gives me an effective opening Or lintel length of 2.098 mso technically for 2mm longer you could order a 2.1. I’d probably Personally rounded up an order a 2.4 Just to be on the safe so i just had that a little bit extra timber available if i needed it Ok, so there you, go that’s our major timber components that make up a wall frame that’s how we work out How Many of them,we need. Obviously that’s only two Walls you would have to go around and repeat that process for all the walls in your house and then you could total up your orders and get that order into the timber yard G’day, again i’m back just let.

  1. Nice video mate

  2. Would you really order all those different sizes? I would have thought it’s easier calculate total linear meters and order pack of 4.8 m. That way you can cut your studs to 2.4 with minimal waste, cut your plates and use any offcuts for noggings.

  3. Bro your channel is a godsend, I recently started a career as graduate engineer in a small firm, and have been daunted by how much my seniors use short hands. Haven’t had too detailed of a browse on your videos yet, but they seem to help a lot with understanding the construction aspect too that uni don’t teach! Keep up the good work mate!

  4. Great video. Thank you.
    As a question, should you include the cripple studs under and possibly over the window or are you referring to a sliding door style.

  5. Perfect mate!! Just about to do this!!

  6. If I wanna build a house, can you please tell me from where do I have to start? Can you do video for owner builders I love your channel

  7. Great, The most useful videos on construction I have found. Just the right amount of detail. Also, covers relevant requirements of the building code. I'm trying to find some videos on gable and shed dormer construction, I know you said previously you might get round to making something on this subject. I hope you manage to eventually. Thanks for making these vids public.

  8. Thank you!!! This was the most clearly explained framing video I've come across!!

  9. very clear and simple explains.much better than my tafe teacher . thanks
