The height of the railing must be between 34 and 38 inches. It must be structurally capable of withstanding a concentrated load of 200 lbs. Or a uniform load of 50 lbs. /ft. Handrail dimensions will be limited due to graspability restrictions. More information on building code definitions for handrails may be found here.
The answer depends on how steep the stairs are. If they're not too steep, then a single standard rail on both sides is enough. But if they are steep, you might want to get two different types of handholds: one for more gradual changes in direction and another for when you need to grab on for dear life.
The conventional rule is that the handrail should be at least as tall as the stairway it's protecting. But because it is possible to overexert yourself when using the stairway, this guideline is only an approximation. A more accurate calculation takes into account the percentage of rise of the staircase. For example, if one were to climb 100 steps in an hour, one would need a handrail that is at least as high as the step stringers to avoid injury. As for what type of handhold to use, the same principles apply here as for any other part of the stairway: choose something that is large enough to be secure but not so big that it is awkward to hold.
In conclusion, a handrail should be at least as high as the stairway it protects.
Handrails must be no higher than 37 inches (94 cm) and no lower than 30 inches (76 cm) from the top surface of the handrail to the surface of the tread, in line with the face of the riser at the tread's forward edge. The distance between each post and its neighbor should be wide enough so that a person standing on the bottom stair will have room to put one foot through the opening between posts without hitting the side of the next-door neighbor's house.
The National Institute for Standards and Technology has recommended that all steps within homes not exceed 12 inches (30 cm) in height to prevent injury due to falls.
The United States Consumer Product Safety Commission estimates that fall injuries are the leading cause of death among children 14 years old and younger. In addition, it is estimated that 10% of people over 65 suffer from some type of dementia disease or memory problem. Because of this, safety experts recommend that any steps within the home be limited to no more than 6 inches (15 cm) to avoid accidents caused by confusion associated with different levels inside a home.
In conclusion, the highest step we recommend is 6 inches (15 cm), which is recommended for those who live in homes where everyone can walk without assistance. If you have any concerns about your own health or the health of your child, please consult with a physician before making any changes to your exercise regimen.
The stair handrail height should be no less than 34 inches and no more than 38 inches. This is calculated by starting at the leading edge of the stair nosing and running an imaginary vertical line up until it reaches the top of the railing. The distance from the bottom of the stair nosing to this line is called the "stair rail height."
The handrail should cover the full width of the stairway. If there are obstructions such as doors or windows that limit how wide the handrail can be, then it is recommended that you install handrails on only one side of the stairway.
The handrail should begin just past the beginning of the first riser and should end at the top of the last riser. For example, if your stairway has four risers, the handrail should span from riser one to riser four.
There are two main types of handrails: wooden and metal. Both provide support for people who may be using the stairs lightly or heavily. A handrail will also make the stairway look cleaner and allow you to add a touch of color without covering all the other details around the stairway.
Stairs are one of the most dangerous parts of any home.
Handrail is 30 inches long. Except for OSHA, all other codes and regulations require handrails to be installed between 34 and 38 inches above the ramp, walking surface, or nose. It suggests a maximum height of 28 inches and a minimum clearance of 9 inches between the child's rail and the adult rail.
These guidelines are recommended by several organizations that research wheelchair accessibility. The National Association for the Blind reports that access with handrails is available to about 70 percent of people who need them.
To determine how high you should install your handrails, first measure up from the floor to the top of the ramp at one end. Multiply that number by two if you will be installing rails on both sides of the ramp. Then add six inches to that number for a total height requirement of between 34 and 38 inches.
The American Disability Actuary estimates that 80 percent of people who need handrails have access to them. That means that two-thirds of people will not need rails that high. If you plan to install handrails on only one side of the ramp, then go with the higher recommendation. If you plan to install handrails on both sides, then go with the lower recommendation.
People who need handrails often complain that they are too high. But research shows that those handrails can be quite effective in preventing falls.
Handrails should be no less than 34 inches and no more than 38 inches above the steps or ramp. When dealing with alternating tread devices or ship ladders, take your measurements above the tread nosings. The railing should be 30 to 34 inches above the floor. If you need more distance, put a post in the center of each stair or ladder step.
The purpose of the handrail is to provide a safe support for persons using the ramp or staircase. It also provides a place for people to grab if they are having trouble maintaining their balance. The handrail should be high enough so that it does not interfere with normal use of the stairs or ramp. It should not be so low as to cause embarrassment to those who must use it. The rail should be strong enough to bear any load that might be placed on it by someone using the ramp or staircase.
When selecting a handrail, give some thought as to how you will attach it to the ramp or staircase. You may want to use cable or belt hooks, etc., or have a variety of lengths so you can fit your handrail to any particular step or landing. Avoid attaching the handrail to the ramp or staircase with nails or screws, since these items will need to be removed if you ever decide to paint or stain the surface beneath them.
