Key Features
✔ Versatile slope selection with common presets (ADA, residential) and a full custom rise:run ratio input.
✔ Comprehensive calculations for required ramp run, actual sloped ramp length, slope angle in degrees, and grade percentage.
✔ Flexible unit options for vertical rise input (m, ft, in, cm) and selectable units for the horizontal run output.
✔ Real-time results that update instantly as you input the rise or change the slope ratio or units.
✔ Clear output display showing target ratios alongside precise calculated dimensions and slope characteristics.
✔ Instant result sharing via a convenient clipboard copy feature for all key ramp parameters and calculations.
How to Use It
- Select Slope Ratio: Choose your desired ramp slope. You can pick from a list of standard presets (like ADA 1:12 for unassisted access or 2:12 for residential assisted use). For a unique slope, select "Custom Ratio" and then enter your specific rise and run values for the ratio (e.g., 1 rise for every 10 run).
- Enter Vertical Rise: Input the total vertical height (Rise) that the ramp needs to achieve. Select your preferred unit of measurement (meters, feet, inches, or centimeters) for this rise.
- Choose Run Output Unit: Select the unit in which you'd like the calculated horizontal 'Run' of the ramp to be displayed. The 'Ramp Length' output will automatically use the same unit you selected for your 'Rise' input.
- Review Calculated Dimensions: The calculator will instantly provide the necessary horizontal 'Run', the actual sloped 'Ramp Length', the 'Slope Angle' in degrees, the 'Grade' as a percentage, and the 'Rise : Run Ratio' based on your inputs.
- Share or Reset: Use the 'Share Result' button to copy a detailed summary of all inputs and calculated outputs. Click 'Clear All' to reset fields to their default state or 'Reload' to start the calculator fresh.
