Standard Door Frame Width

When adding or replacing a doorway, it is important to know some basic numbers and keep them in mind when framing up the new door. There are defined standards for the width of door frames that need to be kept in mind.

• Exterior Door Standards
• Interior Door Standards
• Universal Doorways
• Sizing Door Openings

While these framing standards may seem restrictive, if you enjoy being creative, don’t worry – there is definitely some wiggle room here. Know that there are two common standards for door sizes – one for home exterior doors, and one for interior doors.
PLEASE NOTE: While building codes are fairly standardized, in some areas, they may differ. Be sure to check with your area’s specific building code for door frames before beginning your project.
