How to Properly Plan Stairs | This Old House
/ thisoldhouse
Thank God for RUclipsrs that explain this in more detail.
The rise is 7.69 or 7 11/16 and the run is 9 1/2. The height is 69 1/4 so you would divide that number 69.25 by 9 which gives you the 7.69 rise or 7 11/16. The run is 9 1/2 so you times 9.5 x 8 because you always have one less run. The total run length is 76. Cut off whatever you are using for stair treads off the bottom of stringer. For instance if you are using a one inch thick stair tread cut one inch off bottom making the first rise 6 11/16 tall. The top rise will need to be held down 8 11/16. Lastly cut off the run of the top step for whatever you are using on the face of the rise treads. For example if you are using 3/4 plywood the top run on the stringer needs to be 9 1/2 minus 3/4 which gives you the top tread run of 8 3/4.
I've always wanted too see how Tom did steps, he's a true Craftsmen.
Sometimes I have dreams that I'm Tom Silva and there's no challenge that cannot be conquered. Then I wake up and I'm just me.
Tom S is the MacGyver of TOH and my hero. I do wish he had laid out the math a little more for us.
👍👍 for the c-clamping square to straight edge idea. I’m going to use that on my next set of stairs. Thanks
A master at work. That would take me probably about 100 tries to get done right as I've never done it before haha
Need to mention that most building codes have head height clearance rules for stairs, more likely a problem in interior.
Thank you for making this video! We just bought our first house and were wondering why we felt unsteady using the stairs; the measurements are wrong! So now, we know what the measurements are supposed to be, so we can plan for new stairs! Having the correct measurements and how to calculate them is a game changer!
I liked the idea with the framing square, but you never showed how to calculate the number of treads and risers one would need. I am finding when I see stairs with 9" treads (because of the lip of the finished tread above that), especially with older citizens, they are cautious where they plant their feet so they do not fall. I myself like 12" treads. Would you please show how to calculate stair treads with 12" treads and 7 1/2" Risers? Thank you.
I am building stairs soon in a tiny house that will go to a lofted area. I would like to have storage under the stairs. A mix of drawers and cabinets. Can I build them our of all plywood? Stringers too? How can I have a stringer on the outer portion of the stairs if most of it would need to be cut out for storage?
There's a lot more to it than just that
Wish they had this old house Vocational programs in Urban Community's kids will respect whatever they build with their own Hand's.
You forgot crowning the boards sir. And mention that 37degrees is the default unless split foyer or failed amount of room
Thanks, I like the tip on how to use the square to get even measurements all the way across.
To calculate the number of steps, take the total height which in this case is 69.25, and divide by a number of steps you think will be needed. If the result is over 8 inches the result is a bad number of steps. If the result is in between 7 and 8 inches, the result is a good number of steps. If the result is under 7 inches, the result is a bad number of steps. Total Total Riser height Steps Height 69.25 / 8 = 8 11/16 bad 69.25 / 9 = 7 11/16 good 69.25 / 10 = 6 15/16 bad
To calculate the step length, add the riser height to twice the step length.
The result should be between 26 and 27 inches.
Riser Tread Tread
Height Length Length Total
7 11/16 + 9 + 9 = 25 25/36 bad
7 11/16 + 9 1/2 + 9 1/2 = 26 25/36 good
7 11/16 + 10 + 10 = 27 25/36 bad
Thanks.

Your Welcome! 😎👍
Steps are some intimidating.
SH (step height) is 170 till 180 mm (6.7 inches to 7.0 inches)
But the step depth is the magic number 620 mm (24.4 inches) in a formula.
That is 2SH+1SD = 24.4"
Now take Height 6.7" times 2 = 13.4" + X = 24.4" so X is 24.4 - 13.4 = 11"
Test this (2x) SH = 6.7" + SD = 11" the total shall be 24.4"
All this gives you that is you choose the step height of 7" the depth shall be shorter.
You can do stairs that have longer depth. That is no problem. Just don't do them to short.

Actually, I worked the calculation until I got the same answers that Tommy provided in the video.
FYI: Most code specifications in America are still SAE, not metric measurements.
Good as always. Hello from Germany.
Thx for the video but there wasnt enough on the calc part. Have to know how to calculate rise and run to build atairs.
Great! But what are the required dimensions of the board before it's cut into stringers? (2x8? 2x10? 2x12?)
2x12
Well, he didn't explain the math between the rise and cuts...
yup dislike
I suspected from the start that the video wasn't going to be much of a deep dive, based on its (less than) 4 minute running time. I would really like to hear more about stairs!
Or calculate the tread thickness.
Most pros use the Construction Calculator. It’s a great resource and comes as a phone app now too.
There is no formula between the rise and tread, they are individually figured using the required horizontal length of the entire stair way and the required total height.
How did you figure the angle for the birds Mouth on the bottom?
You need to think about tread thickness, too. For example: If finished floors are 3/4" and tread material is thicker (say 1.25") and you don't lower the risers that 1/2" difference, your first step up will be 1/2" taller and top step up 1/2" shorter than all the steps in between. Riser layout would be the same, but you'd need to cut that 1/2" off the bottom.
You are right that you need to adjust for finished floor but your risers height is measured from finished floor. Your bottom step would be taller until the hardwood or whatever is installed.
@@mpybals8002
Always a good idea to start a story pole with ALL the pertinent information on it. This includes any possible landings, although this set didn't have any.
Tom did everything but tell us how he figured the rise and run.
Lol
the man only works in right angles
Measure 7.5 inches on the sides
Everything but how to do it lol
Wouldn’t you just divide to total height by 7.5” for the rise then multiply the resulting number by 10” for the tread?
Going by the marks of a framing square when laying out stringers, you're almost always guaranteed to be off at least a 1/16nth of an inch. Measuring the hypotenuse is the only accurate method for stringer layout. I rarely see anyone do that.
That's true. I once saw a carpenter use the square, and he gained about an eighth of an inch on each tread. Over sixteen treads, he was off two inches at the top.
@CORNER MARKET PLACE Ok :)
I do stairs just like that the difference is that they give us the whole material cut already so we always have to adjust the stringers a little. It would be nice if they fit perfectly like how it did for this stair master
Tom ran into a little problem on these stairs as a 9 1/2' tread is the minimum tread allowed. He probably has an issue with them sticking out in the hall but I'd make them closer to 10". 2r + t = 25 would give you 9 5/8".
What about picking the right lumber for the stringers? What grain direction works best? What grain direction works best for the treads?
You can ask for "stringer stock" at the lumber yard to receive suitable lumber.
What is the cut you made on the bottom of the stringer that locked in the floor? I never seen anyone explain that
That track saw is the secret weapon!
I love this old house Page! These Guys are the best of the best!
Og seems like a nice guy to work with 💪🏾
Has TOH ever reviewed Larry Haun's videos from the 1970's?
No, Larry Haun's videos were associated with Fine Homebuilding, a competitor.
How did you calculate the notch on the bottom stair?
I was looking for that as well
He forgot to subtract 1/4" to the bottom of the stringer that sits on the floor ,to accommodate for the thickness of the tread which is 1" thick .1" (Tread) - 3/4" (Floor) = 1/4" ,so by taking that 1/4" off the bottom it will lower the top tread 1/4" .Ex: Risers are suppose to be 7 1/2" high ,so by taking that 1/4" off the bottom your first rise at the bottom will be 7 1/4" high and the rise at the top (from the top of the floor to the top of the tread) will be 7 3/4" ,so when you install your hardwood floors or ceramic tiles with sub-floor (3/4") thick and your treads (1") thick all your risers will be equal from bottom to the top .You need to subtract what you intend to put on your floor to the thickness of the tread which is 1" thick .
Yep, I came to the comment section to see if anyone else noticed this.
Trying to design a switchback staircase- I want a rise of 6” and tread of 12.5” - is that allowed? And working with 10’ ceilings on main
What are the minimum requirements for headroom for people who are using the stares?
What is that he has attached to his power saw?
We have to have a 90 (Lshape) staircase going to basement. Two of the floor joists have to be removed to allow for head room. Do the headers that cap off the floor joists have to be supported by a wall under them, or can I keep it open?
I know it is late, but the joists holding the header should be doubled.
what about thickness of tread finish
In Washington State there should had been a safety rail around that mid level floor they working on.
im clueless, Tommy FTW!
what about connecting where can i find 45 degree hangers for stringers
hello I have space which is 98 inches height and 50 inches on the ground. How can those stairs be designed?
Plz can you make a video of your cordless drill
Happy New Year
Riverside California building code doesn’t allow the use of screws, they call for 16ds.
Never a thumbs down. But this topic should have more info.
How to cut stringers for unlevel landing I've hunted for your video an can not find it ,please put it on here
Good stuff per usual. Thanks.
Really l learning from you thanks
What about the pitch of each tread ???
When is the show on? It was on PBS at 7 pm Saturday’s in NY. Can’t find it anymore.
Believe it's strictly online now
In Arkansas it come on PBS Saturday's at 1:00
New episodes
I would think it would be the same everywhere in the US
Let’s see how the top went
Drill a hole where rise and run meets less apt to splitting
You didn't explain the cut that attaches to the board
Your a rock star !
Wow I will never do stairs another way. I like the circular saw with guide/fence/track attachment too
Nick DiFilippo it’s a Festool HKC saw
For almost $900 for that saw and track, I don't like it that much
Scottybravo1 time is money. Most good tools will pay for themselves if that’s the work you do
They are being paid to promote the guide. Any carpenter would be laughed at on the job if they used that guide. I can cut as good as a table saw on any cut, freehand, and so can any good carpenter.
@@thomaswayneward
You are correct about the festool track saw, but having spent over 40 years trying, I still haven't gotten to the level of skill you claim to possess. I haven't seen it in any others, either. What a good carpenter does is work around his deficiencies. I have several homemade track saws, simple masonite and 3/4"x3/4" hardwood saw guide in lengths of 8', 50", and 18" that take the skill of cutting a straight line out of the equation. For most things, I don't even take them out of the truck. But when I'm building cabinets or coffered ceilings, or stairs, they come in real handy for the price of $20.
Building Staircases can be a DIY puzzle box! Another quick and informative video ATOH! 🏠
Didnt show how to get angle on bottom to lay flush
What I do is: After the lay out with the square, LEAVE the pencil mark with the saw blade, this is the template. For the rest of the stringers, put the pencil mark DOWN on each new stringer, and REMOVE the pencil mark with the saw blade. Your stringers should all be the same... Good luck !
How much money would it cost to make a 7-step stone and concrete staircase in front of the house?
If you have to ask, you haven’t saved enough yet
I’m always one step ahead. Like a carpenter. Who builds stairs.
Twice the rise plus the run (2r+R) should be within an inch of 25”. 😉
I don't think he said how wide the stringer board has to be. Basic info...
What would the correct rise and run be on Led Zeppelin's Stairway To Heaven ?
4/4
@@kellyanderson995
I always thought it was NO QUARTER.
riser height = 7.5 in and tread = 10 to 10.5 in.
I just wish the template was better explained. I expected to see it on top or something. :(
I can build stairs after this 3 min video.
It must be nice having a $700 circular saw for a project…
My dad always used these two little brass clamp things when he did stairs idk what they're called
They’re called rafter buttons
Their called square nocks
My old man gave me his recently
This is 3 years old, but for anyone looking on Amazon, they're stair gauges.
Not only that …. measurement for foot or base .
Tim didn’t explain how to calculate the rise and run 🤨
He didn't cover how to figure the tread width. The total length, on a horizontal, of the stairs, always has a requirement. The tread must be adjusted accordingly.
Dude. Rise and run are one thing. Unit rise and unit run are another. Got to be specific man. Vary vary specific.
That's " very, very specific ".
Failed to tell people how you calculated the tread and riser size.
So much missing info.
*Break a hip ... grandma !*

You didn't explain the math..
the math is fifth grade stuff.
I do not like Tommy saying “That’s illegal” 😭
Nails are actually better than screws for 99% of wood framing-the most important thing you want in a fastener for a building unless you are sistering material is sheer strength. I feel like he’s sold out to be more attractive to the undereducated viewer.
This is why men like Essential Craftsman and Larry Haun just can’t be replaced. It bothers me that the kind of work that is typically to be very home-grown is becoming so commercialized.
Nails are plenty good for all carpentry. A single 16 sinker will hold about 400 lbs. so four in a stud is 1600 lbs.
👍👍
I didnt learn anything.
Wrong title on this video
All the years I've been watching this show, How come they never show these guys messing up a project?😄😂😂..
🤷🏽♀️I wanna see some mistakes made by these "master carpenters"..
😁☺️😖😂😅
no mistakes made here
You didn't show the most important things, the 5.5 inch first step, and where it ended up at the top, were you 7.5 inchs down from the top or flush with the top, all you really showed was your little jig.
Lacked detail
I wonder why the hell they don't use metric. It's 2024.
If your up in north Maine
Just use the circular saw to finish cut the stair stringers
That extra meat you cut into with the circular saw doesn’t really matter
🤣🤦🏻♂️😂
poor explanation and incomplete
Didn’t learn a thing
These videos are much too short
As in, "They give you a flyover of a project, but not the substance to complete a job."
They are not teachers, that's for damned sure. They often tell a DIY'er just enough to make them dangerous.
This video was pointless. It didn't show how to lay out stairs whatsoever.
After this 3 minute video with its lack of in-depth techniques and methodology, I'm just going to install an elevator !
Exactly. Left out as much as he included
😂what
This video is tv fluff, skipped the important stuff.
Thumbs down. Explained nothing.
Slight kudos for the board square setup. Otherwise how long a stringer do you need. What’s the run? No math.
Disappointing.
0:40 which idiot designed those stairs. They are good for if you want to fall down. Here the steps are too small
3:17, yet another disaster. the steps seem too high, difficult to carry things up.
Has no one in the US an idea how to design the ideal stair?
@DR PHIL Of course Amsterdam and the UK are bad examples. In other European countries that type of stairs would not get an approval. Guess the family of this old house is originally from England or Holland.
@DR PHIL Yupp
@CORNER MARKET PLACE the steps are too high, the stair is too steep and the entire foot doesnt fit on one stair step. I posted my initial comment 2 years ago.
