How wide is a wheelchair accessible doorway?

Wheelchairs come in different shapes and sizes. According to the U.S. Americans with Disabilities Act, doorways require a minimum of 32” with a maximum of 48”, which would adjust most wheelchairs. (Hallways need 36”). The wheelchair should be able to roll freely and unobstructed through any pathway. Anything less may have to be argued with local inspectors. And the sidewalks should be 88 inches to accommodate two-way travel.
