The International Residential Code, the International Building Code, and the Americans with Disabilities Act mandate that handrails must be no less than 34 inches high and no more than 38 inches high above the stair. A stair calculator can calculate parameters such as rise, total run, angle, stringer length, step height, tread depth, and the number of steps required for a given run of stairs. Handrails must not project into the stairway more than 4 ½ inches, meaning a stairway can’t be less than 31 ½ inches wide with one handrail and no less than 31 ½ inches wide with two handrails.
The standard size for a staircase in a residential home is typically between 9 and 12 feet long, but this can vary depending on the height of the ceiling. To accurately calculate the length of your staircase, measure the distance between each step or riser and do not exceed 7 3/4 inches. The IBC recommends that the minimum distance between two stair railings must always be under 30 inches to avoid accidents.
The standard height of a handrail is between 34 and 38 inches. The current ADA standards dictate that the top of handrail gripping surfaces should be 34 inches minimum and 38 inches maximum measured vertically above the stair. Ramp handrails should extend horizontally above the landing for 12 inches (305 mm) minimum beyond the top and bottom of ramp runs.
To determine the amount of handrail needed, count the number of steps on your stairway and multiply by 13″. Floor level balustrades must be at least 36″ high or 42″ high, depending on local codes, and stair guardrails must be between 34″ and 38 inches. Stairways must have handrails or stair railings on each side, and every stairway required to be more than 88 inches in width must have not less than one handrail.

How much handrail do I need?
It is imperative that handrails be installed at a height of between 30 and 38 inches above the leading edge of the stair tread. Furthermore, they must be continuous and graspable, extending a minimum of 12 inches beyond the top and bottom riser in a horizontal direction. It is also essential that they be installed along the entire stairway.
How many inches should a handrail come up to?
The height of handrails should not exceed 37 inches (94 cm) or 30 inches (76 cm) from the upper surface of the handrail to the tread surface, in alignment with the riser’s face at the forward edge of the tread. This is in response to a letter from Mr. Helmut Haydl regarding Occupational Safety and Health Administration (OSHA) standards for stair rail and handrail heights and corresponding building code requirements.
How high should interior railing be?
The ADA height requirements for handrails in the United States are 34 inches minimum and 38 inches maximum, measured vertically above walking surfaces, stair nosings, and ramp surfaces with a greater than a 1:20 slope. These standards aim to create a safe and enjoyable space for everyone. Handrail height is based on the ADA, IBC/ICC, OSHA, or local building jurisdictions. The ADA is not a building code but a standard for making facilities accessible to the public.
Knowledge of these requirements is crucial, whether a handrail is used alone or combined with existing railing systems. Inline Design provides advisory information and is not liable for non-compliance. Local building codes supersede national building codes.
How to calculate railing quantity?
To measure a staircase for a new stair railing system, follow these steps:
Measure the tread rise, count the number of rises, measure the tread run, measure the tread thickness, measure the nose projections, and calculate the stair angle.
Use a framing square and a ruler or straightedge to determine the exact height of each tread rise.
Use the Keuka Studios Stair Calculator to check the measurements of stairs with identical treads and risers.
Double-check your dimensions by entering the number in the field labeled (D) in the calculator.
By following these steps, you can ensure a proper fit for your new stair railing system. Keuka Studios offers a unique design process and can also provide cable or glass railing systems for existing stairs. By following these steps, you can ensure a proper fit for your staircase and create a unique and functional staircase.
What is code for space between railings?
The International Building Code (IBC) recommends that the minimum distance between two stair railings should be under 30 inches for stair users to have easy access to handrails. Measurements must be taken from the inside surfaces of each handrail, and the IBC does not require people to reach farther for accessibility. This also applies to intermediate handrails, and handrails must be installed on each side in commercial buildings, as per section 1014. 9 in Chapter 10 Means of Egress.
What is the distance between interior railing posts?
To ensure optimal performance, space structural posts no more than 4ft apart center-to-center, with intermediate posts spaced every 4ft between them. This ensures cables remain properly tensioned and deflect as little as possible. Proper tensioning is essential for creating a safe and sturdy system, and after installation, it is vital for a cable railing system to perform optimally for years to come. Following the deck cable railing code is also crucial for a safe and sturdy system.
How much space do you need between railing posts?
The International Building Code (IBC) recommends that manufactured deck railing posts should be spaced no more than 8 feet apart, as they can withstand up to 200 lbs of pressure from any direction at any single point on the railing panel or post. Balusters should be installed close enough so that the space between them is less than 4 inches to protect small children or pets from injuries. Local building codes may have more stringent regulations, so check with your local building department before starting the deck building process. To install safe and sturdy deck railings and railing posts, consult NADRA’s deck safety links or follow the installation guides provided by NADRA.
How high does a railing need to be on a wall?
In accordance with the recommendations set forth in the installation guides, the top surface of the handrail should be situated at an elevation of 34-38 inches above the floor or above the nosing line. This measurement can be taken from the nosings of the steps.
Do I need a handrail for 3 steps?
Building codes require a handrail when there are two or more “risers” in a stair, which is the vertical portion of a stair. A two-riser minimum would mean two steps. Building codes typically apply for new construction or major renovations, and if the work is not subject to inspection, no requirements are required. However, building codes are considered a “minimum standard for safety”, so even if the installation is not subject to inspection, it may be necessary to include a handrail that meets graspability requirements.
Is 42 inch railing too high?
OSHA standards dictate that guardrail height railings must be 42″ high in the general industry, while 42″ plus or minus 3″ is the proper response in the construction industry. The top railing must fall between 39″ and 45″ from the walking surface, regardless of whether it’s a manufactured or built railing. When working with wire rope, it’s crucial to consider sag, as wire rope cannot deflect below 39″ when 200 lbs of force is applied. Regardless of whether it’s a rooftop guardrail system, a temporary railing system, or a job-made railing, the height of the top rail must always be 42″ (plus or minus 3″ in construction).
How tall can steps be without a railing?
The number of steps requiring a handrail depends on the rise requirements, which are the height difference between the bottom of the stairs and their top edge. Most regulations require a rail and handrail for stairways with a total rise of at least three feet. The number of stair treads is not relevant, but the exact height is. Handrails must be provided to all stairways with a rise of at least three feet, and it is essential to consult local regulations for specific requirements.

Mike and Logan demonstrate how to install the Deck Man cable railing system on an interior stair well. This system can be used …
I’m kind of surprised that the horizontal cables are even allowed. They basically provide a ladder so a little kid can climb up and launch themselves over the top. Those rails aren’t to my taste but it’s your house so if you like them that’s what counts. Regardless, nice job on the installation. By the way, I’m old so my taste runs more toward the railing that you removed. 🙂
Yes, the new railing looks nice and modern, but if you have children or if any children come to your house, this is a danger to them. We all know the first thing a child is going to do is to climb railings like this. That’s why the safest railings are verticle. I think in Canada you cannot have a railing like this because it goes against code, for that very reason. It is code legal here in the US, and as long as it looks nice for some people that’s all that matters, and safety is secondary. There are modern railing systems that look just like this, but have vertical rails instead and thus are much safer. To be safe, I’d also put a hand rail on the wall going down the stairs, but I’m no designer, so what do I know. It might interfere with aesthetics.
For the most part, I do not like codes, but in this case, I have to agree that the new railing will not meet the code when and if you try to sell the house. I yelled at the screen “NOOO” when you cut the old railing out. It was a very beautiful wood railing and for that location. I, personally, think you have made a very tragic mistake. I think your work is very good but not in this particular case.
April, thank you for the detail, but the new railing is looks Too modern for the style of your home. Should have left it alone, there was nothing wrong with nice look of the existing railing. I wonder if the new railing even passes building code where in your town for this application since it no longer has vertical balusters.
Looks nice- but unless it is attended to by the owners to keep undesirables away it will be destroyed by various oafs standing, even bouncing, on the wires, just to prove they can effortlessly destroy something to make up for the fact that they couldn’t create something nice ( like that railing) even if their lives depended on it.
I can’t be sure, but I think the new railing is a little bit shorter than the old one. Wondering if that meets safety-code or not. If not, I guess a person could raise that baseboard up a bit by sandwiching it with another (thicker) board underneath the baseboard. (???) Or just use one very thick (beam-like) board. Just an idea. How tall are you, btw? It looks like the handrail is right at your hip. (???)
If I may be so bold, April, that yellow & black power tool you used is a DeWalt “Guaranteed Tough” battery powered RECIPROCATING SAW. 🙂 “Sawzall” is a trade name by Milwaukee and was offered before DeWalt. Old marketing mantra, “Better to be first than best!” Yes, I once worked for DeWalt Marketing. 🙂
Typically, I like your work. In this case, I absolutely do not. I know it’s not my house, however, I am saddened that people so easily destroy a beautiful, classic piece of work that probably took quite a bit of fabrication and time to build and install only to replace it with cheap looking mail order parts.
I’m starting to feel like we’re getting a lot of regurgitated content from you. This railing project really isn’t much different than your deck project. I’ve lost count of the number of dog beds, chicken coops and fence projects you’ve done. I know they get plenty of views but as a long time subscriber, I’m kinda getting bored.
