This tool calculates the ideal ladder height for your specific project based on the height you need to reach.

## How to use the Ladder Height Calculator

This ladder height calculator helps you determine the appropriate ladder length needed to safely reach a desired height when placed at a specific distance from the wall at a given angle.

### Steps to use the calculator:

- Enter the height you need to reach in meters.
- Enter the distance from the wall in meters.
- Enter the angle of the ladder in degrees.
- Click the “Calculate” button to get the required ladder length.

### How the calculation works:

The calculator uses the basic trigonometric formula: *height = length * sin(angle)*.

By rearranging the formula, the required ladder length can be calculated as: *length = height / sin(angle)*.

### Limitations:

- This calculator assumes a simple scenario where the ladder is perfectly straight and leaning against a vertical wall with no deformation or bending.
- The angle must be between 1 and 90 degrees, and the height and distance must be positive values.
- Always ensure that the ladder is placed securely and follow all safety guidelines when using a ladder.
