How to Measure for a New Door
To ensure your new door will fit properly, you must take accurate door measurements. Don't just measure the existing door. You need to measure the rough opening in the wall.
The rough opening is the unfinished gap in the frame where the door will be installed. As a rule, the rough opening should be two inches wider and about two inches taller than the door itself. This extra space provides enough room for the door frame and door jamb, allowing the door to swing open without issues. For example, a standard door that is 36 inches wide and 80 inches tall needs a rough opening of approximately 38 inches by 82 inches.
Accessibility and Building Codes
Building codes often dictate minimum door widths, especially for entry doors and any door required for egress. Furthermore, the Americans with Disabilities Act (ADA) sets standards for wheelchair access.
