Ladder angle
75.5degrees
Angle between ladder and ground.
Vertical reach
4.84m
Approximate vertical height reached.
Explanation
What this calculates
The ladder is treated as the hypotenuse of a right triangle.
Formula
Angle = arccos(base distance / ladder length)
Inputs are validated on screen and converted where unit options are available.
Worked Example
Example result
A 5 m ladder with the base 1.25 m from the wall gives an angle of about 75.5 degrees.

Calculator questions.
What angle should I aim for?
Many ladder checks use the 1-in-4 rule, which gives roughly 75 degrees.
Does this prove a ladder is safe?
No. Check ground, condition, securing, access, duration and whether safer equipment is required.
