## Resource

ADA door clearance requires 32 inches minimum, but a 32-inch door won't get you there. Learn why 36-inch doors became the standard and what every ADA dimension is actually solving. In this episode, Emily spent an entire day in a wheelchair during college and came back with a completely different understanding of accessible design. She walks you through how people actually move through buildings, from doors to ramps to corridors, and explains the human problem behind every ADA requirement. You'll learn door clear width, the 5-pound opening force rule, why pull-side maneuvering clearance is larger, and how the Capitol Crawl changed everything. Beyond doors, this episode covers ADA ramp slopes and the 1:20 threshold that triggers handrail requirements, the guardrail vs handrail distinction that contractors get wrong constantly, the 60-inch turning diameter (not radius), protruding objects and cane detection, and reach ranges for operable controls. 📝 Key topics covered: ADA door clearance: 32-inch clear width and why 36-inch doors are standard Door opening force: the 5-pound rule for interior doors Guardrail vs handrail: 42 inches for falls, 34-38 inches for grip ADA ramp slope: the 1:12 rule and the 1:20 ramp trigger Protruding objects: the 27-80 inch cane detection danger zone Reach ranges: 15-48 inches for operable controls ⏱️ Chapters: (0:00) What Is ADA?
