Ramp Calculation Formula:
From: | To: |
The ramp length calculation uses the Pythagorean theorem to determine the actual length of a ramp based on its vertical rise and horizontal run. This is essential for construction, accessibility planning, and various engineering applications.
The calculator uses the Pythagorean theorem:
Where:
Explanation: This formula calculates the hypotenuse of a right triangle, where the rise and run form the two perpendicular sides.
Details: Accurate ramp calculations are crucial for ADA compliance, construction safety, material estimation, and ensuring proper accessibility for wheelchair users and people with mobility challenges.
Tips: Enter the vertical rise and horizontal run in consistent units (meters, feet, etc.). Both values must be non-negative numbers. The calculator will compute the actual ramp length.
Q1: What units should I use?
A: You can use any consistent unit system (meters, feet, inches, etc.) as long as both measurements use the same units.
Q2: What is the maximum slope for an ADA compliant ramp?
A: ADA guidelines recommend a maximum slope of 1:12 (for every 1 unit of rise, 12 units of run).
Q3: Can I calculate slope ratio with this calculator?
A: While this calculator gives the length, slope ratio is calculated as rise:run. For example, a 1-foot rise with a 12-foot run gives a 1:12 slope ratio.
Q4: Does this work for curved ramps?
A: No, this calculation is specifically for straight ramps. Curved ramps require more complex calculations.
Q5: What if I only know the length and one other dimension?
A: You can rearrange the formula to solve for the missing dimension: rise = √(length² - run²) or run = √(length² - rise²).
