What are the requirements for ramp landings and turn platforms?

Landings must be at least 60 inches by 60 inches (150 x 150 cm) at the top, bottom, every 30 inches (76 cm) of vertical rise, and at any change of direction.

ADA standard mandates a maximum slope of 1:12 (8.33% / 4.76°) for commercial spaces and recommends 1:16 or 1:20 for effortless independent push.

All engineering calculations, structural estimates, and electrical sizing metrics are provided for preliminary estimation only. Always ensure compliance with relevant statutory building codes and occupational safety standards, verified by a certified professional engineer before practical implementation.

Calculation Methodology

Ramp Run Length = Vertical Rise * Slope Ratio (e.g. Rise * 12 for 1:12). Landings = Max(0, Ceil(Rise / 75cm) - 1). Total Footprint = Ramp Run + (Landings * 1.5m).

Frequently Asked Questions

For every 1 inch (or 1 cm) of vertical elevation rise, you must provide at least 12 inches (or 12 cm) of horizontal ramp run (8.33% slope / ~4.76° angle).
