3 min read
Asked by: Rosemary Munoz
The highest permitted standing level on a step ladder is two steps down from the top. A person standing higher may lose their balance and fall. A person’s maximum safe reaching height is approximately 4′ higher than the height of the ladder. For example, a typical person can safely reach an 8′ ceiling on a 4′ ladder*.

The equation will be sine 72 degrees must equal the ratio of the opposite side to the hypotenuse or in this case x divided by 12..

What does 12 ft reach on ladder mean?
Step ladder height = Estimated reach above the ground: 6-foot ladder = 10-foot reach. 8-foot ladder = 12-foot reach. 10-foot ladder = 14-foot reach. 12-foot ladder = 16-foot reach.
What does 10-foot reach on a ladder mean?
So if you know how high you want to reach, let’s say 10′, you would likely purchase a 6′ step ladder allowing you to safely stand almost 4′ above the ground. Select a Height: Step ladder size, approximate highest standing level and maximum reach.
What is the 3 point rule of ladder safety?
To use ladders safely, always maintain three points of contact. That means two hands and one foot or two feet and one hand on the ladder at all times. Moving quickly often results in only 2-point contact. You often have to make a conscious effort to maintain 3-point contact.
How long should a ladder be for a 2 story house?
28′
