How long should a ramp be for a 20 inch rise?
I'm curious to know, when designing a ramp for accessibility purposes, how does one determine the appropriate length for a ramp that accommodates a 20 inch vertical rise? Is there a specific formula or standard guideline that's commonly followed to ensure safety and ease of use for individuals requiring assistance? Understanding this can help ensure that ramps are designed and built in compliance with relevant regulations and best practices.
