This tool helps you calculate the correct slope for ADA-compliant wheelchair ramps.

## ADA Ramp Slope Calculator

This calculator helps you determine the slope and length of a ramp based on given dimensions. By providing the rise, run, and total length of the ramp, you can check if the ramp meets the ADA (Americans with Disabilities Act) requirements.

### How to Use

- Enter the rise of the ramp in inches.
- Enter the run of the ramp in inches.
- Enter the total length of the ramp in feet.
- Click on the ‘Calculate’ button.
- View the result which will include the slope percentage, if it meets ADA requirements, and the required ramp length in feet.

### How the Calculator Works

The calculator uses the rise and run to determine the slope percentage of the ramp. According to ADA guidelines, the slope should not exceed 8.33% (which is a ratio of 1:12).

The required ramp length is calculated by using the total length provided by the user and adjusting it based on the rise and run provided.

### Limitations

- The calculator assumes straight run and rise without any landings or intermediate platforms.
- It does not account for local building codes that may have more stringent requirements.
- Measurements are assumed to be accurate; measurement errors can affect the results significantly.
