Calculating The Required height of Ladder for Any Work
Before calculating the required height of a ladder, you need to consider some factors. Since the extension ladders have some overlap, you need to consider i.e… The 20 feet ladder can only reach a maximum height of 18-19 since you also overlap between the base and the fly section.
Likewise, it would help to consider the angle at which the ladder will rest on the wall. It is impossible to rest the ladder upright as you always need to place it at an angle.
Another practical way is to stand a few rungs from the top of the ladder.
For example: if you want to know the maximum reach of around 35 feet and you have an extension ladder at your disposal, then the ladder height calculation needed is:
Maximum Reach Required-35 feet
Ladder to be used- Extension Ladder
So, let us have a look at the extension ladder height chart now:
Ladder Height | Maximum Reach | Height to Gutter or Top Support Point |
16 | 15 | 9 maximum |
20 | 19 | 9’ to 13’ |
24 | 23 | 13’ to 17’ |
28 | 27 | 17’ to 21’ |
32 | 31 | 21’ to 25’ |
36 | 34 | 25’ to 28’ |
40 | 37 | 28’ to 31’ |
For a maximum reach of 34-37 feet, you can use the ladder height required is 40 feet. Hence, to reach a height of 35 feet, you need a ladder height of 40 feet.
