Use this tool to easily calculate the required length of a handicap ramp based on your specific height and slope needs.

## Handicap Ramp Calculator

This calculator helps you determine whether a given ramp meets the required angle for accessibility purposes. Input the ramp length in feet, the vertical rise in inches, and the maximum allowable angle in degrees to check if the ramp is safe.

### How to Use It:

- Enter the length of the ramp in feet into the “Ramp Length” field.
- Enter the vertical rise of the ramp in inches into the “Vertical Rise” field.
- Enter the maximum allowable angle for the ramp in degrees into the “Maximum Ramp Angle” field.
- Click the “Calculate” button.
- Read the result to see if the ramp is safe or too steep.

### How It Calculates:

The calculator uses trigonometry to determine the actual angle of the ramp. It converts the vertical rise from inches to feet and then calculates the angle using the arctangent function:

actualRampAngle = Math.degrees(Math.atan(riseInFeet / rampLength))

If the calculated angle is less than or equal to the maximum allowable angle, the ramp is considered safe. Otherwise, the ramp is too steep.

### Limitations:

- The calculator assumes that the ramp is straight and does not account for turns or landings.
- Ensure all measurements are accurate, as incorrect inputs will affect the result.
- The calculator does not consider other safety factors such as handrails or surface material.

## Use Cases for This Calculator

### Calculate Ramp Length

To calculate the length of a handicap ramp you need to input the vertical rise and desired slope. The calculator will determine the minimum length needed for the ramp for safe accessibility. This ensures compliance with ADA guidelines for wheelchair users.

### Determine Vertical Rise

By entering the height difference between the starting and ending points, you can quickly determine the vertical rise. This step is crucial to ensure the ramp provides a smooth transition for wheelchair users. The calculator automatically accounts for any height difference.

### Adjustable Slope Calculation

You can adjust the slope percentage to customize the ramp based on specific needs and regulations. The calculator will automatically update the ramp length based on the adjusted slope to maintain compliance with accessibility standards. This feature helps tailor the ramp to fit various settings.

### Calculate Landing Size

After determining the ramp length, the calculator can also provide the recommended landing size at the top and bottom of the ramp. This ensures there is enough space for wheelchair users to safely maneuver on and off the ramp. The landing size calculation accounts for safety and ease of use.

### Optimal Ramp Width Calculation

You can input the desired ramp width to calculate the total surface area required for the installation. The calculator considers the width alongside length calculations for a comprehensive assessment. This feature ensures that the ramp meets specific width requirements for accessibility.

### Evaluate Material Quantity

Based on the calculated dimensions, you can determine the amount of material needed for ramp construction. This helps in cost estimation and planning for the project. The calculator accounts for the dimensions to provide an accurate material quantity assessment.

### Instant Cost Estimation

Through inputting material cost per square foot, you can instantly estimate the total cost of constructing the ramp. This feature helps in budgeting and planning the project effectively. The calculator factors in material quantity and cost for a precise estimation.

### Visualize Ramp Design

The calculator can generate a visual representation of the ramp design based on the input dimensions. This visual aid offers a clearer understanding of the ramp layout and dimensions. It helps in visualizing the final ramp structure before implementation.

### Check ADA Compliance

Once all dimensions are input, the calculator can verify if the ramp design meets ADA standards. This ensures that the ramp is compliant with accessibility regulations for wheelchair users. The ADA compliance check feature helps in ensuring adherence to legal requirements.

### Save and Print Functionality

After completing the calculations, you can save or print the results for future reference or sharing. This feature allows you to keep a record of the ramp dimensions and calculations for project documentation. The save and print functionality enhances convenience and organization.
