A ladder is needed for various purposes in a household, such as reaching the roof of the house, repairing purposes, cleaning the top of the house, windows or gutters, etc.
Are you confused about which height of ladder will be perfect for your 2 story house? So, this post is for you. Here, we will explain to you which rule you should follow to know the ideal height of the ladder that will be needed for your house. Let us start.
What are the uses and types of ladders?
A ladder is an equipment that consists of a series of bards, or we can call them steps, between two distinct lengths of wood, metal or rope, which is used for climbing up or down to a height.
A perfect type and height of ladder is necessary to avoid accidents such as slips, etc. There are various types of ladders available in the market that are being used these days, such as fibreglass, wood and aluminium. They all have their significant properties and are used accordingly.
Fibreglass ladder is most popular these days for professional and personal use as it prevents shock and is rust-resistant, too, as it is non-conductive. It is also durable as compared to other types of ladders.
The next one is a wooden ladder, which is non-adjustable, economical and electrically non-conductive.
The last aluminium ladder is the strongest out of these, lightweight, durable, and corrosive resistant.
There is one more type that is the most convenient out of all is an adjustable ladder. It can be adjusted to any desirable height. It is also called an extension. It consists of two to three more sections of ladders that allow it to get adjusted accordingly.
Now that we are familiar with the concept of types of ladders let us move forward and learn how to calculate the exact height of the ladder that is required for a 2 story house.
How to calculate the length of the ladder required for a 2 story house?
To calculate the desired length, we have to apply four to one rule. Let us see what is this 4 to one rule
4 to 1 rule
This rule says that for every four feet of height of the building, you have to move the ladder one foot away from the wall. The angle made between the foot of the ladder on the ground should be more or less equal to 75 degrees. This will prevent the ladder from slipping.
The average height of a 2 story house is 24 feet, so we will need to place the ladder 6 feet away from the foot of the wall.
How tall of a ladder must be for a 2 story building?
To calculate the height, we need to do some calculations and use our childhood favourite Pythagoras theorem along with the 4 to 1 rule. According to this, the square of the sum of the square of the height and base of a right-angled triangle is equal to the court of the hypotenuse of that triangle.
Let us take the height of the 2 story house to be 24 feet, so according to the 4 to 1 rule, the ladder should be 6 feet away from the foot of the wall, which will be our base. So now we have height and base, and we have to calculate the hypotenuse. After applying Pythagoras’ theorem, we calculated that the length of the ladder should be 24.7 feet. This can be approximately 24 to 25 feet long, with an extension ladder of 28 feet tall.
A ladder is a tool that is used for access to a certain height and fulfils the purpose, and it can be made of fibreglass, aluminium or wood. All of these have different pros and cons. One more extension ladder is used these days that can be adjusted accordingly. To calculate the desired length of the ladder, we apply the 4 to 1 rule along with the Pythagoras theorem. For a 2 story house, you will need a ladder of approximately 24 feet with an extension ladder of 28 feet tall.
You should know how tall a ladder you need for your house, and how tall is a 2 story house. If you still have doubts, then you can comment on them we will try to sort them out as soon as possible.
