Formula and methodology
Formula: angle=atan(height/base distance); ladder length=√(height²+base distance²).
This is right-triangle geometry for a ladder's position. Setup, securement, surface condition, extension above a landing, and occupational safety rules must be checked separately.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Wall contact height — minimum 1.0E-6; maximum 1000
- Base distance from wall — minimum 1.0E-6; maximum 1000
Worked example
| Input | Value |
|---|---|
| Wall contact height | 3.6 |
| Base distance from wall | 0.9 |
Angle≈75.964°; geometric length≈3.711 length units.
Assumptions and limits
- The wall, ground, and ladder are modeled as a flat right triangle.
- Height and base distance use one consistent length unit.
- The result is not a safe-use determination; follow current local ladder guidance.
