Width of stairs in a private house: optimal dimensions and recommendations

Today, quite a lot of people dream of living in their own beautiful and cozy two-story house. If you are engaged in the construction of a private multi-storey building, then you simply need stairs to move between the floors. However, what should be the width of the stairs, the size of the steps and the height of the fence? All this will be discussed later.

Varieties

There are no clear rules that should guide the construction of a structure, since each case is unique. Everything depends on the layout of the building, functionality and ease of use, as well as the purpose of the staircase itself, which you want to receive.

There is a certain classification of structures according to several criteria, on which the minimum width of the ladder depends. All of them are conventionally divided into:

• Workers;
• Inter-floor;
• Input;
• Passing.

In addition, the stairs can be located inside or outside the building, as well as have a straight or swivel shape. The edges of which design and shape to choose, depends solely on your preferences and layout.

Design features

Any staircase, regardless of shape, size and location, consists of several mandatory constructive elements:

1. The attack is a horizontal surface of a step, the shape and dimensions of which depend on the structural features of the ladder.
2. The riser is the vertical surface of the step, which is not mandatory and may not be present in some staircases.
3. Balusters - vertical racks, on which the railings are attached. They play a very important role, because they are responsible for safety.

Dimensions

If you decide to build a ladder on your own, it is very important to calculate the correct dimensions for it, as this affects convenience and safety when moving between floors. The width of the stairs depends on several factors, which will be discussed later.

Security

Any recovery must first of all be safe, so when calculating the height and width of the ladder, many factors must be taken into account, especially if you are children, the elderly and people with disabilities. In addition, the basic requirements dictated by the fire safety rules should be taken into account. This is very important, because in the event of a fire, all tenants at home must be able to safely leave it.

When erecting the fence, balusters should be located at a distance of no more than 15 centimeters from each other. This will be enough to prevent a person from falling from the second floor in case, for example, if he stumbles or slips. And if you have small children, then this gap should be even smaller, so that the child could not stick his head between the balusters and get stuck.

If you are interested in the question of what should be the width of the stairs to the second floor, it is recommended to familiarize yourself with the basic requirements and standards described in the construction documentation. In it you will find many tips and recommendations. If properly observed, you will not only have the optimal width of the staircase in the house on the second floor, but also a high level of security, as well as excellent functionality and ease of use.

The main requirements for the size of stairs in a private house

To date, there is a standard technical documentation, which lists the main requirements for the construction of stairs in a private house. Their observance, while not mandatory, but to have at least some idea is still necessary. Next, the general requirements will be presented.

Requirements for the width of the stairs

The minimum width of the staircase in a private house is 90 centimeters. It is not recommended to make narrower designs, since in case of emergency evacuation, cases of injury are likely. The same applies to the level of the slope of the ladder, which should not exceed an angle of 40 degrees. With a larger slope, the probability of a fall greatly increases.

Optimal step width

The width of the steps of the stairs should be exactly the same, so that in case of moving without light at night you could not stumble and fall. The optimal figure is from 21 to 35 centimeters, and the height should be in the range of 12 to 20 cm. Of great importance is the number of steps in one march. The more of them there are, the higher the probability of injury in the event of a fall. The optimum number of steps in one march, if the recommended width of the ladder step is observed, is twelve.

Requirements for sites and fences

To ensure that the structures are safe and comfortable, the dimensions of the staircases must correspond to the dimensions of its spans. Grounds should not prevent rapid evacuation from the second floor in the event of a fire. The height of the fence must be at least 90 centimeters, and the railing must be able to withstand a load of at least 100 kilograms.

Ease of use

The width of the stairs to the second floor affects not only the safety, but also the convenience of its operation, which is also very important. Therefore, before the construction of the construction, make calculations. What is the width of the stairs should be so that it is convenient to move between the floors?

The width of spans and platforms should be such that two people of medium build can move freely. If we talk about numbers, then for a private house there will be enough width of 130 centimeters. If the house is inhabited by a small number of people, the width of the stairs with limited free space in the house or features of the layout can be reduced to 90 centimeters, but in this case only one person can move around it. In addition, it will be impossible to carry furniture or other large items.

As for the angle of inclination, the most safe and ergonomic are the stairs with a slope of 30 to 40 degrees. For a comfortable moving between the main room and the attic, a ladder with a slope of up to 70 degrees is suitable. This will be enough to go up to the attic, and will save a free space.

When building a ladder it is recommended to make a platform, the width of which is equal to that of the spans. The length of spans is calculated based on several parameters, the main ones being the slope angle and the shape of the ladder. If you can not calculate all the dimensions yourself, then in this case it is better to look for ready-made staircase projects or seek help from a professional builder with the necessary knowledge and experience.

Step sizes are calculated based on your physiological characteristics and growth. The most convenient for moving on the stairs are the steps, in which the width and height are selected in such a way as to provide a convenient step at the usual walking speed. In the average adult, the step length is approximately 62 centimeters. Thus, based on the recommendations described above, with a width of steps of 30 centimeters, their height should be about 16 centimeters.

A few words about the fire escape

Probably, each of us saw on the TV, especially in foreign films, fire escape ladders, which are built from the outside of the room and are designed for emergency evacuation from the apartment or house in case of fire or any other life threatening situation. If you want to build such a structure in your home, you should take into account their specific features.

In terms of their design features, they are almost identical with classical staircases, but they are considerably narrower, so only one person can move around them. In addition, the dimensions of the fire ladders should be calculated exclusively with observance of all rules, recommendations and requirements of SNiP. However, before proceeding to design, you must first determine the type and shape of the ladder, as well as the method of its attachment to the facade of the building.

General tips and tricks

When building a ladder in a private house, it is of fundamental importance to calculate the correct dimensions for it. It is strictly forbidden to take any numbers from the head. When designing and drawing a drawing of a future ladder, it is necessary to consider the following factors:

• The area of the room;
• ceiling height;
• Features of the room;
• The type and shape of the staircase you want to build;
• Type of building and finishing materials;
• Number of residents, their age, physical abilities and physiological characteristics.

Only after you have taken into account all these parameters, it will be possible to start calculating the dimensions of all the elements of the ladder. Only having calculated everything carefully, you will receive a reliable, safe and convenient design. Do not experiment and try to invent something new, because even the slightest mistake made in the design and construction can be fraught with serious consequences. The most important thing - when building a staircase with your own hands, is to think about how, in the end result, all tenants would be safe and comfortable.
