What is the minimum width of a vestibule door?

The minimum width of a vestibule door being 36 inches is based on accessibility standards and building codes that emphasize safe and easy passage for all individuals, including those with disabilities. A 36-inch door provides sufficient clearance for wheelchair users and allows for easier movement of larger items, enhancing overall functionality in high-traffic areas such as entrances to public buildings.

Wider doorways also help in complying with regulations such as the Americans with Disabilities Act (ADA), which mandates specific dimensions to ensure accessibility. This width reduces the likelihood of bottlenecks during entry and exit, making the space safer and contributing to a more effective egress during emergencies.

While other widths may exist for various applications, the 36-inch standard is widely recognized and established to balance practicality with safety requirements.
