How do I ensure my ramp meets ADA compliance using this calculator?

The calculator includes preset slope options aligned with ADA standards, such as the maximum unassisted user slope of 1:12 and comfortable slope of 1:16. Selecting the appropriate preset or entering a custom ratio that meets or exceeds these guidelines will help ensure accessibility compliance.

Can I use this calculator for residential ramp projects?

Yes, the tool offers a specific preset for residential or user-assisted scenarios with a 2:12 slope ratio. This option is tailored for residential settings where the user may require assistance, providing a suitable slope for home installations.

What slope ratio should I choose for an unoccupied chair loading area?

For unoccupied chair loading and unloading, the calculator provides a 3:12 slope ratio preset. This steeper ratio is designed specifically for loading purposes where the chair is not occupied during the ascent or descent.

Does the calculator provide information on ramp length and angle?

Yes, once the rise and run are input, the calculator outputs the slope angle and elevation grade. It also determines the required ramp length based on the input measurements and selected slope ratio.
